What is AAC?
(No Ratings Yet)
Loading ...AAC (.aac) or Advanced Audio Coding is a next generation audio codec developed by Fraunhofer that seeks to preserve audio quality at lower bitrates. High licensing costs have kept this audio codec from the mainstream.
AAC has two formats: MPEG2 Advanced Audio Coding or MPEG4 Advanced Audio Coding.
MPEG2 AAC audio-encoding standard of the format is not backward-compatible with MPEG1 audio. MPEG2 AAC can produce better audio quality than MP3 using less physical space for the files.
MPEG4 AAC audio-encoding standardcan produce better quality and smaller files than MPEG2 AAC. AAC is the audio file format used by Apple in their popular iTunes Music Store. Files may appear on your system with the “.M4A” filename extension. This audio codec is the continuation of the MP3 codec created by Fraunhofer-Gesellschaft. Due to advances in the technology, AAC files encoded at a 96 kbps bit rate sound slightly better than MP3s encoded at 128 kbps.
