Tap a supported file and choose Convert to select the output format, bitrate, and sample rate. Auto is recommended for most files.
Bitrate
Auto / 16k / 32k / 64k / 128k / 160k / 192k / 256k / 320k
Sample rate
Auto / 44.1k / 48.0k / 32.0k / 24.0k / 16.0k
Increasing the bitrate cannot improve quality beyond the source. For 16k MP3 output, select a 24.0k or 16.0k sample rate.
