Companies holding patents for HE-AAC have formed a patent pool administered by Via Licensing Corporation [27] to provide a single point of license for product makers. Patent licenses are required for end-product companies that make hardware or software products that include HE-AAC encoders and/or decoders. [ 28 ]
The 'Music' category is merely a guideline on commercialized uses of a particular format, not a technical assessment of its capabilities. 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.
Represents the amount of information, or detail, that is stored per unit of time of a recording. Common examples of bit rates include MP3 which is recorded at 128–320 kbits/s, CD quality audio (LPCM) which is recorded at 1,411.2 kbit/s, SACD (DSD) which is recorded at 5,644.8 kbit/s, and DVD-Audio (MLP), which is recorded at 18,000 kbit/s. CD
For example, CD audio uses 16 bits per sample, and therefore it will have quantization noise approximately 96 dB below the maximum possible sound pressure level (when summed over the full bandwidth) The amount of space required to store PCM depends on the number of bits per sample, the number of samples per second, and the number of channels.
Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end embedded processors.
The Apple Lossless Audio Codec (ALAC, / ə ˈ l æ k /), also known as Apple Lossless, or Apple Lossless Encoder (ALE), is an audio coding format, and its reference audio codec implementation, developed by Apple for lossless data compression of digital music.

Disc quality: optical disc recorders detect the available speed options based on the data which is available on the disc itself. However, some low-quality discs make a high-speed option available to the software, while the burning process can never reach that speed in practice. The reading and writing process may not happen at a steady speed.
