7 days free · Then $6/month
Switch between versions with zero gap, volume-matched and time-synced. Press 1-2-3-4 and hear the difference immediately.
Leave feedback at exact moments. Click any note to jump straight to that version and timestamp — know exactly what it references.
Share a link with your band, client, or engineer. Everyone's notes in one place — no more scattered email chains and texts.
You bounce a new version. Open it in a separate window. Try to match the playhead position. Switch back and forth while the levels are different and the timing is off. By the time you've figured out how to compare them, you've lost the feeling you were chasing.
That's not a mixing problem. That's a workflow problem.
Manually A/B testing mixes in your DAW between different files
Can't volume-match and time-sync versions to hear the real difference
Notes scattered across Dropbox comments, emails, and group texts
Timestamps in notes — but which version were they even referring to?
Losing track of which version you preferred after five bounces
"Was it Mix_v3 or Mix_v4 that had the better low end?"
Upload up to 4 mix versions side by side. Use keys 1-2-3-4 to instantly solo each version. Add timestamped comments that collaborators can click to hear exactly what you mean. Finally know if the mix actually feels better.
Adjust timing and volume in seconds. Finally compare mixes at equal loudness — hear the actual difference, not just "louder sounds better."
Press 1, 2, 3, or 4 to instantly solo any version. Zero gap. The playhead stays synced. Hear exactly where one mix improves on another.
Leave a note at 1:32 on version B. Anyone can click it to jump right there. No more "around the second chorus, I think?"
Your collaborator leaves a note: "The kick is too loud here." They've tagged it to version B at 1:47. You click it. You're instantly listening to version B at 1:47. No hunting. No guessing.
You can even comment on older versions if there's something you miss from the earlier mixes. Not just the newest — any version, any moment.
All feedback in one place. All context preserved.
Drag up to 4 versions into Mixbinder. MP3, WAV, or AIFF. They load instantly and stay synced.
Match volumes and timing if needed. Then press 1-2-3-4 to switch between versions in real-time. Hear the actual difference.
Add timestamped feedback. Share a link with collaborators. All notes stay in one place until the mix is done.
"I used to bounce 10 versions and lose track of which one actually sounded best. Now I upload them all and just A/B until it's obvious."
"My clients used to send feedback like 'the bass is weird somewhere in the middle.' Now they click a timestamp and I know exactly what they mean."
"The volume matching alone is worth it. I finally know if my changes are improvements or just louder."
"Our band used to argue over mixes in a group chat. Now we all leave notes on the same page. Way less drama."
Everything you need to compare mixes with clarity.
