Choose Your MP3 Audio Quality
This converter provides several bitrate options. A 128 kbps setting creates a smaller audio file, while 192 kbps and 256 kbps provide higher bitrate options. The 320 kbps setting offers the highest selected bitrate. Actual audio quality also depends on the original video's audio track; choosing a higher bitrate cannot restore quality that was not present in the source.
