![]() The use of lossy compression is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. ![]() The quality for stereo is satisfactory to modest requirements at 96 kbit/s in joint stereo mode however, hi-fi transparency demands data rates of at least 128 kbit/s. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.ĪAC supports inclusion of 48 full-bandwidth audio channels in one stream plus 16 low frequency effects channels, up to 16 "coupling" or dialog channels, and up to 16 data streams. MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio which uses a form of lossy data compression. AAC has been standardized by ISO and IEC, as part of the MPEG-2 and MPEG-4 specifications. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. ![]() Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression.
