The Audio compression basically utilizes MPEG 1 standard which is a generic audio compression standard. Audio compression in MPEG unlike vocal coders have coders known as encoders that do not assume the nature of source which generates audio signals but coder itself designs by hearing ability of the consumer at the output Multimedia II.

one or two audio channels sample rate 32kHz, 44.1kHz or 48kHz. bit rates from 32kbps up to 448kbps Each layer has its merits. MPEG-2 audio(described in ISO/IEC 13818-3) has two extensions to MPEG-1, usually referred as MPEG-2/LSF and MPEG-2/Multichannel. MPEG-2/LSF has the following properties: one or two audio channels

1.1 MPEG/audio Features and Applications MPEG/audio is a generic audio compression standard. Unlike vocal-tract-model coders specially tuned for speech signals, the MPEG/audio coder gets its compression without making assumptions about the nature of the audio source. Instead, the coder exploits the perceptual limitations of the human auditory system.

MPEG-1 Layer 3 (or MP3) is a 1- or 2-channel perceptual audio coder that provides excellent compression of music signals. Compared to Layer 1 and Layer 2 it provides a higher compression efficiency. It can typically compress high quality audio CD data by a factor of 12 while maintaining a high audio quality.

Advanced Audio Coding, or AAC files (also known as MPEG-4 AAC), take up very little space and are good for streaming, especially over mobile devices. Requiring less than 1 MB per minute of music and sounding better than MP3 at the same bitrate, the AAC format is used by iTunes/Apple Music, YouTube, and Android. Ogg Vorbis

MPEG-1 and MPEG-2 Layer II Audio Encoding. Description. Lossy audio compression that derives from the MUSICAM audio codec. This format may be referred to as MP2 and employs perceptual compression. This means MP2's compression takes out information that is imperceptible in the human auditory range. MP2 is the dominant audio …
