How it works
Your track goes in, a stage-ready version comes out.
1. Drop in your track
Drag in whatever you bounced. MP3, WAV, M4A, FLAC and OGG all work, and it reads the tempo straight away.
2. Set the key
Move the song up or down in semitones to fit your singer. The tempo never changes.
3. Add the count-in
Click the waveform where the song lands on "one", then pick the sound and volume so it leads in cleanly.
4. Check it and export
Play it back, then export a file that's ready for the stage.

Frequently asked questions
What audio formats are supported?
CountIn supports MP3, WAV, M4A, FLAC, and OGG files, which covers the common formats for backing tracks. Files can be up to 100 MB.
How accurate is the BPM detection?
Our BPM detection analyzes up to 60 seconds of audio for high accuracy. You can always manually adjust the BPM if needed.
Do I need to create an account?
No account needed. Just upload a track and start working. After you buy, you get a unique access link by email.
What does "lifetime access" mean?
Pay once, export forever. No subscriptions. Your access link keeps working.
Is my audio private?
Yes. Preview processing happens locally in your browser. Server uploads are only for export and are deleted after processing.
Can I process multiple tracks?
Yes. Upload and process as many tracks as you need. Each export uses your lifetime access.
Is it called a count-in or a count-off?
Both mean the same thing: the count that sets the tempo before a song starts, like a drummer clicking 1-2-3-4 so the band comes in together. CountIn adds one to any backing track, ending right on beat one.
