Planning to have a phone conversation that might be memorable? Want to record a sound that your N900 plays? Or maybe use your N900 as a dictaphone? Then you need a good audio recorder, and Recaller is a great choice.

Recaller is a nice little widget designed to help you with recording just about any audio, be it system sounds (including internet radio or sounds from games), phone calls or the external sounds. All you have to do is to configure the widget to use a desired recording mode, and tap on it to start a recording, which will conveniently be stored in the directory you specified (MyDocs folder by default).

Recaller can record in three audio formats, the AAC, FLAC and WAV, all of which are perfect for recording voice audio (if you want high quality, go for FLAC, AAC gives you a smaller file but eats more resources for compression. WAV is fast, but the file will be a bit bigger than the AAC one). If you want to automatically record all out/ingoing calls, Recaller can do that as well.

So, grab this great little recording widget from Extras with

sudo gainroot

apt-get install recaller

and forget about having a separate dictaphone app!

Note that recording calls might be illegal in your country. Recording copyrighted music from internet radio streams is also illegal.
