For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint. First public release date is first of either specification publishing or source releasing, or in the case of closed-specification, closed-source codecs ...
ALAC is not a variant of AAC (which is a lossy format), but rather an unrelated lossless format that uses linear prediction (similar to other lossless codecs). ALAC also does not use any DRM scheme; [ dubious – discuss ] but by the nature of the MP4 container , it is feasible that DRM could be applied to ALAC much in the same way it is ...
Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. It was designed to be the successor of the MP3 format and generally achieves higher sound quality than MP3 at the same bit rate. [4] AAC has been standardized by ISO and IEC as part of the MPEG-2 and MPEG-4 specifications.

A lossless audio coding format reduces the total data needed to represent a sound but can be de-coded to its original, uncompressed form. A lossy audio coding format additionally reduces the bit resolution of the sound on top of compression, which results in far less data at the cost of irretrievably lost information.
The HE-AAC profile decoder is fully capable of decoding any AAC profile stream. Similarly, The HE-AAC v2 decoder can handle all HE-AAC profile streams as well as all AAC profile streams. Based on the MPEG-4 Part 3 technical specification. [1] Evolution from MPEG-2 AAC-LC (Low Complexity) Profile and MPEG-4 AAC-LC Object Type to HE-AAC v2 ...
Unlike music streaming services, which typically charge a monthly subscription fee to stream digital audio, digital music stores download songs to the customer's hard disk drive of their device. The customer will have the copy of the song permanently on their disk, provided the track is not deleted by the customer, the disk does not get ...
