Retrocord

Retrocord is a retroactive multitrack audio recorder. It works like a tape that's always recording from your selected input, so when you play something worth keeping, you can save the last few minutes to disk as WAV files — after the fact.

How it works

Choose your audio input and a buffer length. Retrocord records silently in the background. When you want to keep what you just played, tap a duration and slide to capture. Retrocord writes WAV files for the selected window to your device. That's it.

Multitrack support

Retrocord records every channel your audio input exposes, each as its own WAV file. Connect a class-compliant multichannel USB audio interface — such as the Focusrite Scarlett series or similar — and capture individual inputs as separate stems. Import them into your DAW to mix, edit, and arrange later.

Use cases

• Capturing jams and improvisations without arming a DAW
• Recording stems from multichannel audio interfaces
• Field recording, where the moment you want has already passed by the time you'd hit record
• Interviews and spoken word, where restarting a conversation to get a clean take isn't an option
• Practice sessions, rehearsals, and songwriting where good ideas surface unpredictably

Details

• Works with any class-compliant USB audio interface
• Also supports the built-in microphone on iPhone and iPad
• Stereo pairing toggle for interleaved L/R channels
• WAV output to the app's Recordings folder, accessible via the Files app
• No cloud, no account, no analytics — recordings live on your device

What Retrocord is not

Retrocord is not a DAW. It does not edit, mix, process, or export beyond WAV. It does not sync to the cloud or require an account. It writes files to your device, and you decide what happens next.
