Twotrack

Twotrack is a simple audio recorder that allows overdubbing and bouncing to a stereo master track. It’s ideal for musicians who want to record a rhythm track to play over, or can simply be used for higher quality recordings than the standard voice recorder.

Features:

  • recording in 16 bit 44.1kHz wav file format
  • single level undo
  • mp3 and wav file import
  • free version is fully functional – just has ads as well
  • records in the background as a service, so you can play to a metronome or loop, or check your mail

Setting latency adjustment

Latency is the delay between when you sing or record a sound, and when it is actually recorded by the app. Android has particularly poor latency (as high as in the hundreds of milliseconds which is crazy) so here’s a way to adjust the app settings to allow for this:

  • Firstly record some hand claps or other percussive sounds, then press the bounce button.
  • Without headphones plugged, and with the volume turned up reasonably high, press the record button again.
  • If (which is almost always the case) there is a latency problem, then your new recording will be slightly before or after the original.
  • Adjust the latency setting accordingly under the settings dialog.
  • Repeat the recording (step 2)
  • After a bit of trial and error you’ll find the recording sitting much closer to the original and that’s your best setting.

FAQs

Why isn’t there a metronome or click track?

I decided to keep the app as simple as possible, and it is possible to record while listening to a metronome as described here.

How can I convert my track to mp3 or another format?

The simplest solution is to download a media conversion app, and use that on the file titled project_name.wav in the project directory

Where are my recordings stored?

Two track stores its recordings on the external storage in a folder called “twotrack”. Inside that are individual project folders. Inside those folders are the following:

project_name.wav – the main stereo master track

overdub.wav – the last overdub

project_name.wav.bkp – the last backup version of the master track (for undo purposes)

overdub.wav.bkp – the last backup version of the overdubbed track (for undo purposes)
