Time-Synced CommentsFeedback at the Exact Moment

“Around the second chorus” is a guessing game. A comment pinned at 2:41 isn't. Concerto ties every note to a timestamp on the waveform, on the version it's actually about.

How It Works

Comments That Know Where They Belong

Everything here ships in Concerto today, on the free plan.

Comments at Timestamps

Leave a comment at the moment you're hearing. Click the timestamp on any comment and the playhead jumps straight there.

Markers on the Waveform

Timestamped comments show up as markers on the timeline, so you can see where the conversation is happening at a glance.

Threaded Replies & Reactions

Clarify feedback in replies without cluttering the main thread, or acknowledge a note with an emoji reaction.

Voice Memos

Some feedback is easier to sing than type. Record audio right into a comment: a melody idea, a rhythm, a reference.

Comment Resolution

Mark feedback as resolved when it's handled. Resolved comments collapse to a single line so the open items stay visible.

Comments Become Todos

Turn any comment into a todo on the song's task list, and it resolves automatically when the todo is done.

The Difference in Practice

No made-up percentages, just the trade you're actually making:

  • Without“The vocal feels buried somewhere in the second verse”
    With ConcertoA comment pinned at 1:23, on the exact version being discussed
  • WithoutFeedback scattered across texts, emails, and voice memos
    With ConcertoEvery note in one thread, next to the audio it refers to
  • Without“Wait, which bounce are you listening to?”
    With ConcertoComments live on a specific version, so context never gets lost
  • WithoutOld notes that nobody remembers addressing
    With ConcertoResolved comments collapse; open ones stay in view until handled
