Classy audio for classy people

Hertz is a simple audio recorder that doesn't compress your sounds into oblivion. Most "sound recorder" applications on the marketplace - and even the built-in Android Sound Recorder - save your audio into the 3GPP format. This makes anything other than simple voice recordings sound like they've been put through a meat grinder.

Hertz records your audio straight to the uncompressed WAV format, at a sampling rate of your choosing. No processing or compression. Just higher sample rates for higher-quality recordings. You can then grab it off the Android's SD card and do whatever you want to it.

You can get a free copy off the Android marketplace, or from here if you have installing from unknown sources switched on (not recommended).
