Spotlight: Voisi Recorder is a pretty cool Android voice recording app that wants you to beta-test it
Moving on to functionality, Voisi Recorder features almost everything you'd expect. You can record phone calls and store voice notes. These can be sync'd with ongoing calendar events and recorded in just one click right from the notification bar. This way, you can easily start, stop, and browse through your recordings.
You can also leave text notes, listen, and share your recordings. For keeping things alive in times of danger, one can also backup their recordings and messages to their email account. Not everything recordable is to be recorded, though! For that, the user's able to choose what calls to record - be it all calls, unknown numbers, or just calls from your contacts.
In regards to sound quality, Voisi features a number of enhancements to make the most out of your device's microphones. There are echo, noise suppression, and silence detection algorithms on-board. And in addition to that, we have Bluetooth headset and speaker connectivity taken care of.
