AAC has slightly better sound quality than MP3 of the same bit rate. We recommend 192 kbps for music and 128 kbps for voice.
It's usually best to keep the original. If the file is going to be included in a video editing project, choose 48 kHz.
5.1 channels or more are stereo.Mono combines the left and right sounds into one. For files containing only voice, such as lectures or phone recordings, mono is sufficient.
