MP4 files are saved using the Advanced Audio Codec (AAC-LC) for sound. The frequency is set to 44100 Hz, and the bitrate is 128 Kbps. You can specify a variety of bitrates for the sound to be encoded. The higher the value the better the quality of sound. Setting high bitrates produces larger files.
