The WMA codec offers greater file compression than the MP3 codec, enabling storage of more digital audio tracks in the same amount of space when compared to MP3s at the same level of quality. ● AAC/M4A - Advanced Audio Coding (AAC) is a lossy audio compression format. Audio files that have been encoded with AAC are generally smaller in size and deliver a higher quality of sound than MP3. ● Bit rate - Bit rate denotes the number of bits per second used by a digital music file. The size and quality of a compressed digital audio file is determined by the bit rate used when encoding the file. ● Sampling frequency - Sampling frequency is the rate at which the samples of a signal are converted from analog to digital (A/D conversion) per second. ● Multisession - Multisession is one of the methods for writing data to media.

MP3 conversion of an audio track can reduce the file size by approximately a 10:1 ratio (Sampling: 44.1 kHz, Bit rate: 128 kbps) with virtually no perceptible loss in quality. The compression reduces certain parts of sound that seem inaudible to most people. Monitor, climate, audio, phone and voice recognition systems 4-51
