Vocal tuning follows your key, and you can choose it
With Major or Minor chosen, notes are now tuned to the key your take reads as when that key is clear, and notes you sang in tune stay where they are. The tuning screen also has a Key choice; leave it on Detect to read the key from your take.

Mastering no longer turns a loud song down
When you ask for no particular loudness, the master is now at least as loud as the file you uploaded, within the range professional masters reach. Before, a loud upload could come back quieter than it went in.
ChangedStudio
Every service waits for your button, and every result can run again
Mastering no longer starts on its own as soon as a file arrives; like the other services, it waits for you to press its button. Options are shown as tiles you tap, and every finished result offers “Adjust and run again”.
ChangedStudio
The Library files every result under its song
Results whose original file you deleted now stay with their song instead of moving to a separate list at the bottom.
ChangedStudio, Legal
The free minutes are given once per email address
Deleting an account and signing up again with the same address no longer brings ten new free minutes. The privacy policy explains the small record we keep to know this.
NewStudio
Add a video, and get the video back with its sound processed
Video files can now be added in the Studio. Your browser takes out the sound and uploads only that, so the picture never reaches our servers, and “Save as video” puts the processed sound back into your original file.
NewStudio, API
Restoration can keep only the voice
The new “Keep only the voice” repair takes away music and every other sound behind a voice. “Background to keep” sets how much of the room stays.
NewStudio, API
Mix a vocal over a beat from two files
Mixing now reads the file names people use, such as “vocal”, “voice” and “beat”. With “These stems are unmixed” on, a raw vocal buried far under the beat is raised to the level finished records use. A reference track now moves a mix halfway towards it, as in mastering.
NewStudio, API
Vocal tuning can take a whole song
With “This is a whole song”, the voice is taken out of the music, tuned and put back, and the rest of the song is left as it was. A little of the original voice stays in the music and is not moved.
NewStudio
Download the preview of a result, or send it to another service
A result you have not bought now offers “Download the preview (MP3)”, as the pricing page says the free plan allows. Every finished result also has “Use in another service”, and restoration says when it found nothing that needed fixing.
ChangedStudio
“Reduce noise” starts unticked
Most recordings people restore are finished songs, where noise reduction can take away more than noise. It now waits until you tick it.
ChangedStudio, API, Legal
Results no longer carry an AI mark
Euphona works on your own recordings and creates no audio of its own, so results no longer carry a machine-readable AI mark or the line about it. Our AI transparency notice explains when that would change.
NewWebsite
Try mastering on the home page, and see your own numbers
The mastering demo now sits right under the home page's first screen. When it finishes, it shows your track's measured loudness before and after, and a switch plays the master at your original's loudness or at its full loudness.
ChangedWebsite, Studio
Every page opens in the dark theme
The site, the Studio and the sign-in pages now open dark. The light theme is still one tap away in the header.

Six guides: mastering in Logic Pro, FL Studio and Ableton Live, and more
Mastering in each of those three apps, mixing a vocal over a beat, using a reference track, and loudness on YouTube.
ImprovedStudio, API
“Remove hum” takes out mains hum and leaves bass notes alone
Hum removal could mistake a bass note for hum and take it out, and it missed buzz with strong overtones. It now removes only the steady hum of mains power and its overtones, and a recording without hum comes back unchanged.
NewWebsite
Two guides: making a song louder, and removing noise from a video
One explains where loudness comes from and how to raise it without clipping. The other covers cleaning up the sound of a video, from the recording to the export. Both are in every language this site speaks.
ChangedWebsite, Studio
Checkout asks for your country, not your street address
Paying no longer asks you to type a full street address. Checkout asks for your country, and for a postcode only where your card needs one.
ImprovedStudio, API
Mastering no longer pushes quiet passages further down
A stage that turned the quietest moments of a song further down is switched off: it did the opposite of what mastering engineers do. Quiet intros and breakdowns now keep their place in the song.
ChangedStudio, API
A reference track moves your master halfway towards it
Copying another song's tonal balance exactly also copied what belonged only to that song. Mastering now moves your track's balance halfway towards the reference you add.
ImprovedStudio, API
Splits into four, five or six parts come from a newer model
With six parts, piano and guitar now come out as parts of their own; before, most of the piano stayed in “Other”. Two-part vocal and instrumental splits are unchanged.
FixedStudio, API
“Reduce noise” measures the hiss properly and spares held notes
Noise reduction underestimated the hiss in a recording, so it removed little of it and could dull a long held note. It now measures the hiss across the whole file and treats steady music as music.

A WhatsApp button now sits on every page of this site. Pressing it opens a chat with us in WhatsApp, and the privacy policy now describes what WhatsApp receives when you do.

Unused minute packs and long-form hours can be refunded within 14 days
A minute pack or a purchase of long-form hours that you have not used at all is now refundable: ask support within 14 days of buying it and we refund it in full, withdrawing its minutes or hours. Once any of it has been used, it is not refundable, except where the law gives you a right that cannot be excluded.

Annual plans now get their renewal reminder about 45 days ahead
The email we send before an annual plan renews, with the date and the amount, now arrives about 45 days before the renewal instead of about 30. Monthly plans still get theirs about seven days ahead.

One analytics answer for the website and the sign-up and sign-in pages
The website and the pages where you sign up or sign in used to ask about analytics separately. Now you are asked once, on whichever you reach first, and your answer applies to both, as does any later change to it.

A seller-details page for Japan
Japan's Act on Specified Commercial Transactions asks an online seller to state who it is, how to reach it, its prices, payment, delivery and cancellation terms. A new page states these for Euphona, and the Japanese site links it at the foot of every page.
ChangedLegal
The privacy policy says when the law can delay a deletion
The privacy policy now says that where the law requires us to keep data, for example for a legal claim, deleting it can be delayed until that obligation ends.
ChangedAPI, Legal
Files sent through the API now count against your workspace's storage
Files you upload with an API key, and the results of API jobs, now count against the same storage allowance as everything else in your workspace: the storage your plan includes, or 2 GB on the free plan. An upload or job that would not fit is refused before anything is stored or charged.
ChangedWebsite, Studio
Every plan keeps every version you make
The pricing page and the Studio's billing page said the free plan kept version history for 7 days and Creator for 90. Neither limit was ever applied: as the privacy policy says, your audio and results are kept until you delete them, on every plan. Both pages now say so, and your plan's storage allowance is the only limit.
FixedStudio
The Download button on a Studio result now delivers the file
Pressing Download on a finished result could leave you on the same page with nothing downloaded, because a setting of ours made your browser stop the download before it began. Downloads from the result screen now go through.
ChangedWebsite
The Proof page is withdrawn
The Proof page published restoration figures measured on September 22. The restoration engine has changed since and the figures were not measured again, so we took the page down rather than leave them standing.
ChangedStudio, API
Mastering's default keeps true peak at −1.0 dBTP
The default master now delivers at −10.6 LUFS with true peak at −1.0 dBTP, the ceiling Spotify recommends. It used to deliver at −9.7 LUFS with peaks up to −0.1 dBTP. The ceiling menu offers Automatic (−1.0) and Full scale (−0.1), and you can still set your own target.
FixedStudio, API
24-bit WAV files use the plain header Spotify asks for
Our 24-bit mono and stereo WAV files carried the extended WAV header, which Spotify's audio requirements say not to use. They now use the standard one, with the audio itself unchanged. If a platform refused a 24-bit WAV from us before, export it again.
FixedStudio
Uploads keep going when you open another Studio page
Opening another page in the Studio used to stop an upload in progress. Now it carries on, every other page shows how many files are still uploading, and closing or reloading the tab asks you to confirm first.
FixedStudio
Uploads wait out a dropped connection instead of failing
When the connection drops, an upload now shows “Reconnecting”, waits for the network to come back, and continues where it stopped. A busy moment on our side slows an upload down rather than ending it.
NewStudio
Choose the same file again to finish an interrupted upload
If a reload or a closed tab stopped an upload, choosing the same file again continues it from where it stopped instead of starting over. A file that already arrived is not sent twice, and an upload that never finished is cleared away after a day.
ImprovedStudio
Spatial audio says before you start if Atmos ADM is not in your plan
The spatial audio forms now show that Atmos ADM export is not included in your plan before you press Start, instead of refusing it afterwards.

The minutes line in the Library is easier to tap
The link showing how many minutes you have left was too small to tap reliably on a phone. It now meets the 44-pixel touch target the rest of the Studio uses.

This changelog
Every change you could notice, dated by the day it went live, with a feed you can follow in any feed reader.
NewWebsite
Two guides: LUFS vs true peak, and how to make an acapella
One explains why a master needs both numbers checked and which limits apply where. The other covers the rights first, then three ways to get a vocal on its own, how to deal with bleed, and how DJs match tempo, key and phrase.
FixedFree tools
The loudness meter now passes every EBU test case its page lists
Loudness range was sampled once a second instead of ten times, which put it up to about 4 LU off on music whose level changes often, and the loudest-moment readings could miss a short burst. Both are fixed, and 5.1 files are now weighted the way the standard says.
ImprovedFree tools
The meter shows peak-to-loudness ratio and what each service does
It now shows PLR and the loudest 400 ms beside the other readings. Its platform cards say which figures the service publishes, and for Spotify it works out how far a quiet track is lifted before its peaks stop it.
FixedWebsite
The loudness guides now match their sources
Apple publishes no loudness target for music, and its own guide says Sound Check can raise quiet tracks; YouTube publishes no figures at all. Our guides said otherwise in places. They now say what each service actually publishes.
FixedWebsite
The Dolby Atmos guide states Apple's loudness rule correctly
Our Atmos guide called −18 LUFS a target. Apple's rule is a limit: a master must not be louder than that. The guide now says so, adds Apple's −1 dBTP peak limit, and names the source.
ImprovedStudio, API
Clipping repair rebuilds the peaks a loud recording lost
When a recording is too loud, the tops of its waves are cut flat. This is called clipping. Restoration now rebuilds those peaks instead of smoothing over the gap, and on every recording in our test set the new repair measured better than the old one.
FixedStudio, API
Restoration no longer undoes its own repairs
The last step of a restoration could squash the peaks a repair had just rebuilt. When a restored file needs to be quieter, it is now turned down evenly, so the repair survives.
ImprovedStudio, API
“Reduce room” removes more echo and leaves clean audio alone
The optional room-reduction setting in restoration was rebuilt. On our test recordings it now removes more of the room's echo than before, and changes the parts that had no echo less.
FixedStudio, API
Spatial ADM masters now open in the standard's reference renderer
ADM is the file format used to deliver Dolby Atmos music. The EBU's reference renderer refused every ADM master we made; now 5.1, 7.1.4, 9.1.6 and object masters all render in it. If you exported an ADM master before this date, export it again.
FixedStudio, Free tools, API
Tuned vocals and separated stems stay below digital maximum
A tuned vocal or a separated stem could peak just above the highest level a digital file can hold, and distort when you brought it into your own project. Both are now turned down evenly when needed, as mastering and restoration already were.
NewStudio, API
Line up a doubled vocal with the lead take
In vocal tuning you can now add a lead take. The timing of your take is then moved, moment by moment, to follow the lead, in the same pass as the pitch correction.
NewStudio, API
Change a single note and run the tuning again
A finished tuning run now lists every note: when it starts, what was sung, and where it was moved. Pick a different note for any of them, or keep it as sung, and run the same take again with one button. It works on a phone, and the API accepts the same note changes.
ImprovedStudio, API
Vocal tuning lands closer to the note you meant
Singers often slide into a note, so its first moment is a poor guide to where it is going. Tuning now reads the whole note before choosing where to move it, and it measured closer to the intended note on every take in our test set.
ImprovedStudio, API
Slides, scoops and grace notes stay as you sang them
Very short movements between notes are no longer pulled onto their own semitone, which made a slide sound like a staircase. They keep their shape. A very short retune time still gives the hard-tuned effect if you want it.
ImprovedStudio, API
Tuned vocals keep their vibrato and their airy top end
Tuning dulled the highest frequencies a little and flattened some vibrato. Both now come through closer to the original take.
ImprovedWebsite
The sign-in page says it also creates accounts
“Start Free” led to a page titled only “Sign in”, which looked like a wrong turn to someone new. The page now reads “Sign in or create your account”.
FixedWebsite
Product pages now describe only what each service delivers
We checked every product page against what the Studio really returns and removed what it did not deliver. The mastering report is described as what it shows: loudness, peak level and loudness range, before and after. The stem separation page says it can return six parts, including guitar.
FixedStudio
Minute packs show the date they expire
The billing screen showed how long a minute pack lasts, but not the date it runs out. It now shows the date.
FixedAPI
Two API list filters now work as documented
Listing files by status could return a short page and report no more results. Listing jobs by creation date ignored the date filters. Both now behave as the reference says, and an empty request body gets a clear error.
FixedStudio
The “new sign-in” email gives advice that works
This email told you to reset your password, but Euphona has no passwords: you sign in with a code we email you. It now sends you to your account page to sign the other device out, and suggests securing your email inbox.
ChangedLegal
Five legal documents updated to match the service
The privacy policy, terms, AI transparency notice, accessibility statement and copyright policy now describe sign-in by emailed code and the five free tools that run in your browser. Every earlier version stays readable on the site.
NewStudio, API
Save a payment card without buying anything
You can now add a card in Settings without making a purchase. A live API key now needs a card on file; test keys still do not.
ImprovedStudio, Free tools, API
Vocal and instrumental splits always use our separation model
If the model cannot run, the job is now retried rather than finished another way. That includes the free vocal remover.
ChangedAPI
API: jobs no longer return a model_versions field
Job responses describe the targets you asked for and the file you got, not the machinery that made it. If your code read model_versions, it will now find the field absent.
ImprovedStudio, API
Vocal tuning explains its scale choices and reads your key
The default scale stays “Chromatic”, which moves each note to the nearest semitone; on real singers it matched the intended note more often than any key-based choice. The Studio now says this beside each option, and the report names the key of your take when it is confident.
ChangedStudio
“Mixing & Mastering” in the Studio is now called “Mixing”
It takes your stems and returns one balanced mix, ready for mastering. It never ran mastering, so the old name promised a step it did not do. Old links still work.
FixedStudio
Deleting your account now also ends your subscription and free-tool files
Deleting your account now cancels your subscription at once, so it does not renew. It also deletes the vocal remover results you moved into your account, which deletion used to leave behind.
NewWebsite
Nightly encrypted backups, with a restore test every week
Every database is backed up each night into an encrypted file, and every Sunday the newest backup is restored into a scratch database to check that it works. Both have run on schedule since September 18, and the security page now says so.
ChangedStudio
Sign in with an emailed code instead of a password
Enter your email address and we send you a code. The email also has a link that fills the code in for you. Google sign-in still works, and if the email cannot be sent the screen tells you at once.

One click from the pricing page to payment
Choosing a plan now takes you straight to payment. If you need to sign up first, the plan you picked is remembered through sign-up. Minute packs have their own “Buy minutes” button.
FixedWebsite
The website recognizes when you are signed in
Signed-in visitors were shown sign-up prompts. The header now offers the Studio, and the pricing page offers a direct checkout instead.
NewAPI, Studio
Set your own monthly API spending limit
Settings now has a control for the most your API keys can spend in a month. Before, the limit was a fixed default you could not see or change. Work you start in the Studio is not affected.
FixedStudio
Studio error pages now have a main heading
Screens like a missing job or an expired invitation now start with a proper heading, which helps people who move around a page by headings with a screen reader.
ChangedWebsite
The pricing page now says what the terms say about refunds
A note under the minute packs said a pack you had spent nothing from was refundable. The questions on the same page, the terms and the Studio's billing screen all say a minute pack is not refundable once purchased, and the note now says so too.
ImprovedStudio
A simpler result screen
A finished result now opens with the before-and-after player, one sentence on what changed, and the download. Measurements and re-run settings are one tap away. The text you meet on arrival went from 443 words to 156.
ImprovedStudio
Library: search as you type, filter, and grid or list
Your tracks start higher on a phone's first screen. Search runs as you type, you can filter by service, and you can switch between a grid and a list. Status marks differ in shape as well as color.
FixedStudio
Buying in the Studio works again
Pressing Subscribe, buying minutes or buying a track could leave you on the same page with nothing happening. Purchases now go through, and a track purchase shows the right next step.
The Studio reopened after maintenance that began on September 8. The Studio changes below arrived with it.
NewStudio
The Studio opens on your Library, and every track has a page
Your tracks come first, with your remaining minutes in one line at the top. Open a track to see everything you have run on it, and start another service on the same file without uploading it again.

Compare a new version with the one before it
When you run a track again, you can switch between your upload, the new result and the previous version, all played at the same loudness. You can also search your library by track name.
ImprovedStudio
Results explained in plain words, with help one tap away
The result screen opens with a sentence saying how much louder your track became, and how that compares with the level streaming services play at. The account menu has “Help & guides” and a working Contact support link.
NewStudio, API
Uploads continue after a dropped connection
If your connection drops during an upload, it continues from where it stopped instead of starting again. This matters most on mobile data and with large files. The API offers the same through the open tus upload standard.
NewStudio
Invite people to your workspace
On the Professional and Max plans, the owner can invite people by email, give them a role and remove them, from a Members page in Settings. An invited person sees the workspace and their role before they accept.
NewStudio
Export a record of everything you made
Settings has an export listing your workspaces, what you made, its measurements and what it cost, with a download link for each file you can download. The delete-account section links to it, because deleting cannot be undone.

A job waiting for processing capacity says so
When no processing machine is free, the job shows “waiting for capacity” and nothing is charged while it waits. If capacity does not come back in time, the job stops with that reason, and nothing is charged.
FixedStudio, API
Cancelling a run takes effect at once, and is not charged
You can cancel a run that is waiting or working, and a cancelled run is not charged. A cancelled job no longer keeps its place in the queue.
FixedStudio
The library lists your songs, not every file we made
Finished files such as a master sit under the run that made them instead of appearing as separate tracks. Each run shows the loudness of what it delivered, so repeated runs of one song are easy to tell apart.
FixedStudio, API
Finished files show their real format
A file's details showed the format of your upload, not of the file we made, so a 24-bit master from a 16-bit upload was labelled 16-bit. The audio was always right; now the label is too.
ImprovedStudio
Results appear without reloading, and the first run is easier
A result appears as soon as the run finishes. A banner reminds you to confirm your email address and can send a new link, and on phones the upload area tells you to tap.
NewWebsite
A Proof page with measurements you can repeat
The Proof page shows how our processing measures on a public-domain recording, with the steps to repeat each measurement yourself, including the results that do not flatter us.
NewWebsite, Free tools
Waveforms on every before-and-after preview
The previews on the product pages and the vocal remover draw a waveform for each version, on the same scale, so a louder result looks taller. One position control moves them together and works from the keyboard.

Vocal remover: buy the download without signing up
You can pay once for the separated files without making an account, and a free account still keeps the result in your library. The free tool now takes tracks up to five minutes, down from fifteen; longer songs run in the Studio.
FixedWebsite
The homepage no longer jumps while it loads
On phones the page shifted upward when its font arrived, moving whatever you were about to tap. It now stays still: the layout-shift score on a mid-range phone went from 0.110 to 0.000.
ImprovedWebsite
Clearer pricing cards, and sign-in buttons on tablets
Each pricing card says who the plan is for and has its own button, and the free plan shows $0. On tablets and small laptops, “Start Free” and “Log in” sit in the header.
ImprovedFree tools
The key finder shows which keys mix well with yours
The BPM and key finder now leads with the song's key and explains the neighboring keys DJs mix between.
FixedFree tools
The vocal remover could refuse to split a file
Starting a split while the file was still being read made the tool ask you to try again, and then refuse the retry as a duplicate. Every upload now gets its split.

Pricing states the support reply time as a number
Paid plans now show the promise plainly: a first email reply within two business days.

The developer page says what a test API key really gives
It said test keys return watermarked output, which was never built. It now says what happens: you can try the whole flow, upload to download, without paying, and you get a preview; the full file needs a purchase.

Wide screens use their space, and the developer page shows a request
On large screens many pages left their right side empty. Those sections now hold something useful, such as a real API request and its response on the developer page.

Text across the site is easier to read
Long paragraphs use a darker text color, raising contrast from 5.39:1 to 14.2:1 in the light theme. Body text has a real italic, and step-by-step sections no longer squeeze words into very short lines.

A status page with live checks
The status page shows whether each part of Euphona is working. Planned work is labelled “Under maintenance” rather than “down”, and the page no longer reloads itself, which had sent screen-reader users back to the top.

Launch day: sign-in and the Studio did not work for about five hours
For about five hours after Euphona went live on September 5, you could not sign in or create an account, and the Studio and the vocal remover did not work. Parts of the service were failing to start, and our release checks did not notice. We fixed it the same evening, and every release now has to show that each part starts before it goes live.
