Say hello to our new overdubbing feature, now live in the Boombox mobile app.
This feature was requested by people who are looking for a simple way to ideate and record new ideas without having to fire up their DAW. Overdubbing was designed to give you a quick way to record a simple multi-track demo using only your phone and a pair of headphones.
Here’s how it works…
Select a foundation track, or record a new voice memo
First, you’ll need the foundation track. Upload or select any stem file (for instance, a looped drum sample), or use the voice memo feature to create a new recording.
Got your file ready? Good. Click into that audio file’s player page and you’ll notice a button at the bottom of your phone’s screen labeled “record overdub (beta)”.
Give that button a tap.

Record your overdub
Next, you’ll be brought to a screen containing your audio waveform, and a “start recording” button. Important: you’ll need a pair of headphones to be able to listen to your foundation track and record on top of it at the same time.
Feel free to tap a specific part of the waveform to start from, or just hit “start recording” and it will default to recording from the beginning of the track.

Save your overdub
Once you’ve recorded, the app will take you to a screen where you can review the mix. You have the option to start over, or continue by saving the new overdub. It will save a copy of the new stem, as well as a blended mix of the stem and your original foundation track. Feel free to rename these as you see fit!
From here, repeat the process on top of your new mix as many times as you like until you’re satisfied.

That’s it! We hope this gives you a new way to print your new ideas down as soon as they hit you.
That’s it for now, I’ll be in touch with more updates in the coming weeks. Wishing you the best of luck out there with your music and, as always, happy creating.
