Timestamped Comments

Timestamped comments let you leave precise feedback on a track group. A comment may carry an optional point timecode or a start/end timecode range alongside the required track-group anchor.

This guide covers how to create, manage, and organise timestamped comments in The Library.


When you add a comment while a bounce is loaded in the waveform player, include a timecode for the moment you are discussing. A comment may store a single timecode or a start and end range.

Comments are anchored to a track group and may also carry a track, bounce, file path, Dropbox file ID, or file-system identity. This lets feedback remain tied to the relevant work while still providing file-specific context.

The Library stores optional file identity details alongside the required track-group anchor. When a file-specific reference is available, use it to make the feedback clear; do not rely on a filename alone as an ownership or access check.


  1. Select a track group in the grid to open the activity panel
  2. Click the Comments widget to expand it
  3. Make sure a bounce is loaded in the waveform player — you’ll see the bounce name in the dropdown at the top of the widget
  4. Type your comment in the input field at the bottom
  5. Press Enter or click the send button to post

Add or confirm the timecode before posting so the note identifies the intended moment.

If you want to describe a section rather than one point, include both a start and end timecode when creating the comment.

Double-click a waveform position to create a single-point comment at that timecode.


File-specific anchors help identify comments that relate to a bounce. The track-group anchor remains available when a direct file association changes.

For the selected track group, the Comments tab in the activity panel can show a count badge:

  • Hot badge (🔥) — appears when five or more comments were created within the last 48 hours
  • Standard badge — shows the total comment count for the track group

Pinning requires a collaborator row with master_split > 0. Pinned comments render before unpinned comments.


You can update the content of your own comments at any time:

  1. Find your comment in the list
  2. Click the edit icon
  3. Modify the text and save

Updating a comment changes non-empty content only; it does not mutate its anchor or timecode fields.

To remove a comment you posted:

  1. Click the delete icon on your comment
  2. Confirm the deletion

Deleted comments cannot be recovered. If you’re working on a shared track and need to remove feedback without losing the discussion context, consider editing instead.


When you share a track group with collaborators, they can also add timestamped comments while they have current scoped access to the track group. This makes it easy to collect feedback from producers, mix engineers, or artists without switching tools.

Collaborators see the same bounce selector and comment panel. All comments are visible to everyone with access to the track group, regardless of who posted them.

Your comments remain linked to your account. If you leave a track group, your comments stay with the file but your name remains attached as the author.
