From the first bounce to the approved mix,without losing a single note.
Upload every version, send the band a link and get their feedback at the exact second. Comments turn into a checklist, and every change is approved by listening to it.

Try it the way the band would.
It's the real page the band gets, with a COR song in two versions. Hit play, tap the waveform to leave a note at that second, switch between v1 and v2 without losing your spot and give your OK. Nothing is saved: reload and it starts again.
- Play without opening the song
- Tap the waveform: note at that second
- v1 / v2: same second, other mix
- “Happy with it” or “I preferred the old one”
- Press and hold: approve the record
A player built for mixes.
I built it from scratch for listening to mixes. The file you upload is the file that plays: we don't re-compress or convert it.
- Your file, untouched
- WAV, AIFF, FLAC, MP3 or M4A, never converted. What comes out of your DAW is what the band hears.
- A/B at the same second
- Switch from v1 to v2 with no gap and without losing your place.
- Level-matched
- Each version's loudness is matched, so you compare the mix and not which one is louder.
- What changed
- Marks the parts of the waveform where the new version sounds different.
During the beta you can only upload MP3.
From note to stamp.
Nothing stays buried in the group chat. Everything the band asks for ends up ticked off or approved.
Notes at the exact second
They open your link, type their name and tap the waveform where something's off. No accounts, no instructions, right from their phone.
Every note is a task
To do, to approve or closed, with its instrument and its timestamp. Merge the duplicates and tick them off in the studio.
Approved by ear
Upload the new version, mark what you changed and the band hears that section before and after. If it's a yes: stamp.
Mixkeeper Live. Your master, on their phone.
A plugin for the last insert on your master bus. The band hears whatever comes out of your DAW from a link and leaves notes at the exact bar. Like having them on the studio couch, minus anyone touching the faders.
In the workshopVST3 and AU first, Pro Tools after. Not downloadable yet.
1On the master bus
Last insert, after the limiter. What you hear is exactly what they hear.
2Sign in, pick the song
Sign in once with Mixkeeper, pick client, project and song (or a free session) and hold “Go live”.
3The band listens and comments
They open the link, no account. Every note lands at the bar in your DAW, with thumbs-up and replies. When you're done, the session is saved as the next version and the notes as tasks.
Two ways to listen
Session ~0.3 s · Almost in sync with you, to talk it through over Meet or Zoom.
Listen a few seconds · Buffered and gapless: keeps playing with the phone locked, over Bluetooth or in the car.
What's here. What's next.
We update this as things ship. Everything on the left works today.

Links to the exact second
Share “listen from 2:31” and the song opens right there.
Gapless, level-matched A/B
Switch from v1 to v2 at the same second, levels matched so you judge the mix, not the loudness.
Notes that are tasks
At a second, over a section or dictated. Each one lands in the checklist and the band signs it off by listening.
Approval by majority
You decide how many in the band must give the OK. If they don't get there, you close it.
What changed between versions
Marks the parts of the waveform where the new version sounds different.
Notes into your DAW
Export the notes as markers for Reaper or as MIDI for any DAW.
No accounts for the band
They open the link, hit play and comment. On their phone, light or dark, in three languages.
Your studio page
Bio, your best tracks, Spotify and a button to book a session.
You control the link
Downloads on or off, latest version only or all of them, and switch it off whenever you want. One link for the record or for a single song.
Agreed revisions
Unlimited, or the number you choose for each job. The band sees how many they've used, so there are no arguments at the end.
In the workshop6
Mixkeeper Live
In invite-only beta now. A VST3 and AU plugin on your master: the band hears the session live with your time, bar and tempo, and when you're done you drop the bounce on the plugin and it's the new version.
Any audio format
WAV, FLAC, AIFF or MP3, exactly as it leaves your DAW, never converted. Each version shows its format, in case you have the same one as WAV and MP3.
Email updates
“New version”, “the band approved”, “you've got new notes”. No more chasing people on WhatsApp.
Final delivery
WAV and MP3 masters, instrumentals, stems and the DDP built in the browser, all in one place. Downloads unlock once the band has paid, and heavy files are removed once they have them.
Proposals
A proposal that tells the story of the job: what you'll do, when, what's included and what it costs, from your templates and with any discount you want for each band. They open it as a link, and when they accept, the project sets itself up.
Pro Tools (AAX)
Live inside Pro Tools too.

FAQ
No. They open the link and type their name. If they like, they can sign in with Google so their comments show as verified.
Yes. Every project has its link and every track can have its own, which only opens that track and its notes.
You can delete versions you no longer need. Their comments move to the next version, so no note is lost.
WAV, AIFF, FLAC, MP3 and M4A, and it plays exactly what you upload: we don't convert or re-encode it. Each version shows its format in the player. Every plan takes every format, the free one too. During the beta you can only upload MP3 up to 50 MB.
Yes: the app, the band's links and this page are in English, Spanish and Valencian/Catalan.
5 GB in whatever format you like, with unlimited tracks, versions and projects, plus the whole notes, checklist and A/B system. To give you an idea, 5 GB is about 400 five-minute songs as MP3 or about 60 as WAV. It never expires. Right now we're in a closed beta and you need an invite to sign up.
