2. High-resolution audio - Wikipedia

   en.wikipedia.org/wiki/High-resolution_audio

   Approximate dynamic range and bandwidths of some high-resolution audio formats. High-resolution audio is generally used to refer to music files that have a higher sampling frequency and/or bit depth than that of Compact Disc Digital Audio (CD-DA), which operates at 44.1 kHz/16-bit. [2]

3. Comparison of audio coding formats - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_audio_coding...

   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.

4. Opus (audio format) - Wikipedia

   In July 2024, YouTube rolled out an additional high quality audio format option, 256 kbit/s Opus, to YouTube Music Premium subscribers. [63] Since 2016, WhatsApp has been using Opus as its audio file format. [64] Signal switched from Speex to Opus audio codec for better audio quality in the beginning of 2017.

5. Advanced Audio Coding - Wikipedia

   This is especially true at very low bit rates where the superior stereo coding, pure MDCT, and better transform window sizes leave MP3 unable to compete. While the MP3 format has near-universal hardware and software support, primarily because MP3 was the format of choice during the crucial first few years of widespread music file-sharing ...

6. Audio file format - Wikipedia

   An Audiobook format, which is a variable-bitrate (allowing high quality) M4B file encrypted with DRM. MPB contains AAC or ALAC encoded audio in an MPEG-4 container. (More details below.) .act: ACT is a lossy ADPCM 8 kbit/s compressed audio format recorded by most Chinese MP3 and MP4 players with a recording function, and voice recorders .aiff ...

   In popular usage, MP3 often refers to files of sound or music recordings stored in the MP3 file format (.mp3) on consumer electronic devices. Originally defined in 1991 as the third audio format of the MPEG-1 standard, it was retained and further extended—defining additional bit rates and support for more audio channels —as the third audio ...

8. MiniDisc - Wikipedia

   en.wikipedia.org/wiki/MiniDisc

   The music format was based on ATRAC audio data compression, Sony's own proprietary compression code. Its successor, Hi-MD, would later introduce the option of linear PCM digital recording to meet audio quality comparable to that of a compact disc. MiniDiscs were very popular in Japan and found moderate success in Europe. [4]

9. ATRAC - Wikipedia

   en.wikipedia.org/wiki/ATRAC

   MiniDiscs recorded in this format are incompatible with older players. In a test conducted by an independent firm, but financed by Sony, it was concluded that ATRAC3plus at 64 kbit/s is equal in subjective sound quality to an obsolete MP3 encoder at 128 kbit/s. [16] Performance against modern high quality MP3 encoders was not evaluated.
