Timestamped audio feedback

Feedback that lands on the beat.

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.

Snare feels 2dB louder than last mix, can we back it off?

Pushed the vox up 1.5dB in the bridge and pulled reverb send. Better?

Why studios switch

Audio feedback, where it belongs.

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.

Timestamped comments on the waveform

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.

Stem-level review

Upload stems, clients can solo, mute, and comment on individual stems. Perfect for "let's just adjust the drums" conversations.

A/B version comparison

Play v3 and v4 back-to-back at the exact same timestamp. Difference audible; opinion informed.

Client-friendly review links

No client account, no download, no explanation. Send a link, they hear the mix in a browser, they click the waveform to leave notes.

Loudness reference built in

LUFS, true peak, dynamic range shown on the same view as the waveform. See the trend across versions.

Export the approval receipt

When a client approves, Amplify stores the version, timestamp, and (optionally) their signature. Great for release delivery.

Take a look inside

Two things that reshape the review cycle.

◆ 01 · Stems

Solo, mute, comment — on any stem.

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.

  • Unlimited stems per version
  • Import from ProTools, Logic, Ableton, Reaper, FL
  • Waveform per stem, individual pan/gain controls
  • Session bounce integration for iterative masters

◆ 02 · Sessions

Listen together. Remotely.

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.

  • Sync playback across up to 24 listeners
  • Live cursor showing where each listener is in the timeline
  • Room chat + voice notes for real-time discussion
  • Session recording auto-saved to the project

People at the mixing desk.

I've been mixing records for eighteen years. Amplify is the first tool that made client review a thing I actually look forward to rather than dread. Comments on the timeline changes everything.

Our podcast studio does 40+ episodes a month across 8 clients. Amplify's client-side review links save me maybe 6 hours per week of "which draft is which" over email. It's paid for itself in the first fortnight.

The live listening session got us to buy in. We're a small game audio team, our composer works remotely. We do all our music-to-picture reviews on Amplify sessions now, and the composer says it feels closer to being in the room than any other tool she's used.
