As hardware players supply it, the format is highly demanded by music fans. It has been widely spread in Apple production and is being used by default in iTunes. |
Technical details | 🔵 The format conception is similar to MP3, but it is more advanced. Being able to execute larger compression, it is represented as a separate segment of MPEG-4 standard used to create compact audio files. AAC is highly efficient with variable and continuous bitrate, with a sampling frequency of 8-96 kHz. The current version complies with the standard of ISO/IEC 14496-3. Compression is performed based on an auditory masking effect that provides data reduction with no deterioration for sound quality. |
