About the Audio Quality

Audio quality mainly depends on Bitrate (kbs) which is the number of samples per second times the number of bits per sample, audio channels (mono, stereo or multichannel), and the compression codecs.

The reason why compression methods are used is to save storage space on devices. The most common compression format is MP3, which is lossy but not very obvious for most people. MP3 files commonly have a bitrate of 128 kbs (maximum up to 320 kbs). By contrast, uncompressed audio as stored on an Audio CD could have a bitrate of 1,411 kbs. Other lossy audio formats include AC3, AAC, M4A, WMA, OGG, APE, MKA, and so on.
