9.1. Quality
Choose the quality here (0 to 7). Default is 5, best quality is 7, smallest file size is 0.
This setting effects how much your sound sample will be compressed. Higher quality
settings result in larger MP3 files.
The quality setting is just a way of selecting an average bit rate, or number of bits per
second, for a recording. When this setting is lowered, recordings are compressed more
(meaning worse sound quality), and the average bitrate changes as follows.

sound quality.
