Amplify is where audio work gets reviewed. Timestamped comments, stem-level notes, version comparison, client-friendly review links. Built by producers who spent too many hours reading "sounds a bit off at 1:42, maybe?" over email.
Every producer knows the flow: send a WAV, get an email back saying "the thing around 2:15 could be tighter". Amplify puts the comment on the pixel of the waveform where the thing actually is.
Clients click the waveform, leave a note. The note lives at the timestamp. Never read another "at about 1:42 or maybe 1:44" comment again.
Upload stems, clients can solo, mute, and comment on individual stems. Perfect for "let's just adjust the drums" conversations.
Play v3 and v4 back-to-back at the exact same timestamp. Difference audible; opinion informed.
No client account, no download, no explanation. Send a link, they hear the mix in a browser, they click the waveform to leave notes.
LUFS, true peak, dynamic range shown on the same view as the waveform. See the trend across versions.
When a client approves, Amplify stores the version, timestamp, and (optionally) their signature. Great for release delivery.
Upload individual stems from your DAW export. Amplify presents them stacked with the master. Clients (or your mix bus partner) can solo individual stems, mute others, and leave stem-specific comments. "The drums are too loud in the chorus" becomes a comment pinned to the drums stem at the chorus timestamp.
Start a session, invite anyone by link. Everyone listens at synchronised playback, sees each other's live comments, can pause the room, drop pins together. It's the closest thing to being in the same studio, and for remote sessions it's the closest anyone gets.
Free forever for two active projects. Full app, every feature. If it doesn't fit your studio, close the browser.
