Sound and voice recorder for Android uses RAW microphone data to capture every sound and records in lossless format (PCM WAV). Records stereo audio - listen with headphones and feel surrounded by the sound.

• raw MIC data (captures all sound)
• also recording with screen OFF
• stereo MIC (if device has 2 MICs)
• select the Audio Source (UNPROCESSED / CAMCORDER / MIC / DEFAULT)
• sample rate 8kHz to 192kHz (older devices may not support all the sample rates)
• bits per sample selection 16-bit (high quality) / 8-bit (record files to use in some embedded systems)
• ajustable gain 0 to 60 dB or automatic (look-ahead AGC)
• AGC processing step selection 10ms to 500ms
• AGC measured amplitude averaging factor A_avg 0 = max. amplitude 1 = buffer average

• stereo / mono channel selection
• option to swap left / right channels
• left / right channel balance +/- 10 dB
• keep screen ON - option so that device does not enter sleep mode
• disable ringing and vibration while recording - option so that the recording does not get ruined by the phone ring or vibration
• in-app audio player (listen to the recordings)
• free NO ADS only limitation is recording stops after 10 min. per recording which is more than enough for recording one song.

You have to see the magic of automatic sound level / gain control (AGC) especially if you use to record meetings / lectures. It works as follows: it amplifies the quiet sounds to capture all but then if a loud sound happens it gets reduced volume to not damage your ears.
