Versions

Versions are individual audio file iterations within a track. Each time you upload a new mix or revision, it becomes a new version — automatically numbered and organized in chronological order.

Every version keeps your complete project history, so you can review feedback from each iteration and always jump back to previous mixes.

Creating versions

Every track starts with its first version (v1) when you upload the initial audio file. As you iterate, each new upload becomes v2, v3, and so on.

To upload a new version:

Open the track
Click "New version"
Drag and drop an audio file or click to browse (WAV or MP3)
Optionally add an upload note describing what changed
Click upload

Upload notes

Upload notes help collaborators understand what changed in this version. A quick note like "Fixed vocal level in chorus" or "Added drum reverb" saves time and keeps everyone aligned.

Upload notes appear next to the version and help you track your decision-making process across iterations.

Audio player

The audio player shows a waveform visualization of the version with playback controls and comment markers.

Playback controls

Play/Pause — click the play button or press spacebar
Seek — click anywhere on the waveform to jump to that time
Zoom — use zoom controls to see more detail in the waveform
Time display — shows current time and total duration

Only one version plays at a time across the entire track. If you start playing a different version, the current one stops automatically.

Keyboard shortcuts

Spacebar — play/pause
Click waveform — seek to time
Zoom controls — adjust waveform detail level

Listening and presence

Rebounce tracks who's listening to each version and shows real-time presence when multiple people are reviewing at the same time.

Listen tracking

When you listen to a version for 15 seconds or more, you're counted as a listener. Your avatar appears in the "Listened by" section at the bottom of the version.

Listen tracking only counts forward playback — seeking backward or jumping around won't count as listening time. This helps identify who has actually reviewed the version versus who just scrubbed through it.

Real-time presence

When you're actively listening to a version, your avatar appears as a floating presence indicator on the waveform. Other collaborators can see exactly where you are in the track in real-time.

This makes remote sessions feel more collaborative — you can see who's reviewing at the same time and follow along with their playback position.

Time-stamped feedback

Rebounce's feedback system lets you leave comments at specific points in the audio. Comments appear as markers on the waveform and can be replied to, resolved, or reacted to with emojis.

Leaving a comment

To leave a comment at a specific time:

Play the version or click the waveform to position the playhead
Click the waveform at the point where you want to comment
Type your feedback in the comment box
Press enter or click "Comment"

The comment appears as a marker on the waveform. Click any marker to read the full comment and replies.

Region comments

For feedback that applies to a longer section (like a verse or chorus), you can create a region comment:

Click and drag on the waveform to select a time range
Type your feedback
The comment appears with start and end times

Region comments help you give feedback on entire sections rather than single moments.

Comment threads

Comments support threaded replies. Click any comment to open the thread and add a reply. All collaborators can see and respond to comments in real-time.

Resolving comments

When you've addressed a piece of feedback in a new version, mark the comment as resolved:

Open the comment thread
Click "Resolve"
The comment is marked as resolved and collapses

Resolved comments are hidden by default but can be shown again if needed. This keeps the feedback view focused on what still needs attention.

Emoji reactions

React to comments with emojis to acknowledge feedback without adding a full reply. Click the emoji icon on any comment to add a reaction.

AI feedback summaries

When you upload a new version, Rebounce analyzes all unresolved feedback from the previous version and generates a summary of important points.

The AI summary appears as a task list at the top of the new version, highlighting feedback that should be addressed. This helps you:

Remember what you needed to fix
Ensure important feedback doesn't get lost
Stay focused on unresolved issues

Summaries are generated automatically in the background after you upload a new version. Click any item in the summary to jump to the original comment in the previous version.

Downloading versions

You can download any version in multiple formats with embedded metadata.

To download a version:

Open the version
Click the three-dot menu (⋯)
Select "Download audio"
Choose your format:
- Original — fastest, original format and quality
- WAV — uncompressed, best for importing to a DAW
- MP3 — compressed, good for sharing previews
- FLAC — lossless compression, archive quality

All downloads include track metadata:

Artist name
Track title
Version label
Year, BPM, key, ISRC (if set)
Lyrics (if set)
Artwork (if uploaded)

Metadata embedding happens automatically in the browser, so your downloaded files are ready for distribution or import without manual tagging.

Master designation

The master is the final, approved version of the track — ready for distribution or delivery. You can designate any version as the master.

To set a version as master:

Open the version you want to designate
Click the three-dot menu (⋯)
Select "Set as Master"
A crown icon appears on the version

Only one version can be the master at a time. Setting a new master removes the master badge from the previous one.

Master designation helps everyone on the team know which version is final and makes it easy to find the approved mix when you need to download or share it.

Deleting versions

Workspace admins and track owners can delete versions. This action is permanent and cannot be undone.

To delete a version:

Open the version
Click the three-dot menu (⋯)
Select "Delete version"
Confirm the deletion

Deleting a version removes:

The audio file
Waveform data
All comments on that version
Listen tracking data

Use deletion carefully. If you're unsure, keep old versions — they don't count against storage limits and can be helpful for reference.

Version access and permissions

Version access follows track permissions:

Workspace members — can upload new versions, delete versions, and comment
Track collaborators — can view, listen, and comment (cannot delete or upload)
Shared links — limited to viewing

Tips

Document changes in upload notes

A quick note describing what changed makes it easier for collaborators (and your future self) to understand the evolution of the track. Instead of "New version," write "Fixed vocal sibilance" or "Adjusted drum mix."

Use the AI summary before uploading

Before uploading a new version, check the AI summary from the previous version to ensure you've addressed all important feedback. This prevents missing critical notes and reduces back-and-forth iterations.

Mark the master when final

Once a version is approved and ready for distribution, set it as the master. This signals to everyone that the track is complete and makes it easy to find the final version later.

Review listen tracking

Check the "Listened by" section to see who has reviewed each version. If key collaborators haven't listened yet, you might want to follow up before assuming feedback is complete.

Keep old versions for reference

Don't delete old versions unless necessary. They serve as a project history and can be useful for A/B comparisons or recovering ideas from earlier iterations.

Resolve comments as you go

Mark comments as resolved when you've addressed them in a new version. This keeps the feedback view clean and helps collaborators see what still needs attention.
