Recaller could also be called Rec-all er :-) If you have it, I see no need for the others anymore. You can really record "everything" with it:
- In Dictaphone mode, it captures the sounds of the microphone (and the system), same as (maemo)recorder.
- In System mode, it only captures audio produced by the device (no mic input). This is handy to record e.g. FM radio or Internet radio or even Video audio (CPU might be the limit :-)
- If auto-recording is enabled, it will record each call, automatically switching to mic/phone or bluetooth recording (depending if a BT handsfree device is connected)
- You can switch between different encoding formats such as WAV and AAC, depending on your needs (e.g. AAC makes smaller files, but uses more CPU/power).
