Compare MOV with AAC:
|Full name||QuickTime File Format||Advanced Audio Coding|
|File extension||.mov, .qt||.aac|
|Developed by||Apple Inc.||Bell Labs, Fraunhofer Institute etc.|
|Type of format||Media container||Audio compression format|
|Introduction||QuickTime File Format (QTFF) is a computer file format used natively by the QuickTime framework. The International Organization for Standardization approved the QuickTime file format as the basis of the MPEG-4 file format. Because both the QuickTime and MP4 container formats can use the same MPEG-4 formats, they are mostly interchangeable in a QuickTime-only environment.||Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. AAC has been standardized by ISO and IEC, as part of the MPEG-2 and MPEG-4 specifications.|
|Technical details||The format specifies a multimedia container file that contains one or more tracks, each of which stores a particular type of data: audio, video, or text (e.g. for subtitles). Each track either contains a digitally-encoded media stream (using a specific format) or a data reference to the media stream located in another file.||AAC 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. 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.|
