• Stereo sound is converted to mono sound.
• The audio sampling rate is converted to 8 kHz.
• Audio is compressed.
As the steps above are relatively trivial and non-controllable except for the last step, we only consider audio coding in
this section. For audio-video files, you can select one of the two options in the "Audio format" field:
• Music, normal compression. For high quality audio containing music and/or some other more demanding material.
IMA ADPCM is used, resulting in 32 kbps.
• Speech, high compression. If the original file contains only speech or if a small file size is more important than the
sound quality. The AMR 10.2 kbps mode is used.
