2. MP3 - Wikipedia

   en.wikipedia.org/wiki/MP3

   CD audio is 44100 samples per second. The number of bits per sample also depends on the number of audio channels. The CD is stereo and 16 bits per channel. So, multiplying 44100 by 32 gives 1411200—the bit rate of uncompressed CD digital audio. MP3 was designed to encode this 1411 kbit/s data at 320 kbit/s or less.

3. Audio coding format - Wikipedia

   en.wikipedia.org/wiki/Audio_coding_format

   An audio coding format[1] (or sometimes audio compression format) is a content representation format for storage or transmission of digital audio (such as in digital television, digital radio and in audio and video files). Examples of audio coding formats include MP3, AAC, Vorbis, FLAC, and Opus. A specific software or hardware implementation ...

4. Audio codec - Wikipedia

   en.wikipedia.org/wiki/Audio_codec

   An audio codec, or audio decoder is a device or computer program capable of encoding or decoding a digital data stream (a codec) that encodes or decodes audio. [1][2][3][4] In software, an audio codec is a computer program implementing an algorithm that compresses and decompresses digital audio data according to a given audio file or streaming ...

5. Audio file format - Wikipedia

   en.wikipedia.org/wiki/Audio_file_format

   An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression. The data can be a raw bitstream in an audio coding format, but it is ...

6. 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.

7. Sound recording and reproduction - Wikipedia

   en.wikipedia.org/wiki/Sound_recording_and...

   Digital recording and reproduction converts the analog sound signal picked up by the microphone to a digital form by the process of sampling. This lets the audio data be stored and transmitted by a wider variety of media. Digital recording stores audio as a series of binary numbers (zeros and ones) representing samples of the amplitude of the ...

8. Advanced Audio Coding - Wikipedia

   en.wikipedia.org/wiki/Advanced_Audio_Coding

   Advanced Audio Coding is designed to be the successor of the MPEG-1 Audio Layer 3, known as MP3 format, which was specified by ISO / IEC in 11172-3 (MPEG-1 Audio) and 13818-3 (MPEG-2 Audio). Improvements include: more sample rates (from 8 to 96 kHz) than MP3 (16 to 48 kHz); up to 48 channels (MP3 supports up to two channels in MPEG-1 mode and ...
