2. Variable bitrate - Wikipedia

   en.wikipedia.org/wiki/Variable_bitrate

   Variable bitrate. Variable bitrate (VBR) is a term used in telecommunications and computing that relates to the bitrate used in sound or video encoding. As opposed to constant bitrate (CBR), VBR files vary the amount of output data per time segment. VBR allows a higher bitrate (and therefore more storage space) to be allocated to the more ...

3. Average bitrate - Wikipedia

   en.wikipedia.org/wiki/Average_bitrate

   Average bitrate. In telecommunications, average bitrate (ABR) refers to the average amount of data transferred per unit of time, usually measured per second, commonly for digital music or video. An MP3 file, for example, that has an average bit rate of 128 kbit/s transfers, on average, 128,000 bits every second. It can have higher bitrate and ...

4. MP3 - Wikipedia

   en.wikipedia.org/wiki/MP3

   The most evolved LAME MP3 encoder supports the generation of VBR, ABR, and even the older CBR MP3 formats. Layer III audio can also use a "bit reservoir", a partially full frame's ability to hold part of the next frame's audio data, allowing temporary changes in effective bit rate, even in a constant bit rate stream.

5. 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.

6. Comparison of video codecs - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_video_codecs

   For real-time and non-buffered video streaming when the available bandwidth is fixed – e.g., in videoconferencing delivered on channels of fixed bandwidth – a constant bitrate (CBR) must be used. CBR is commonly used for videoconferences, satellite and cable broadcasting. VBR is commonly used for video CD/DVD creation and video in programs.

7. Constant bitrate - Wikipedia

   en.wikipedia.org/wiki/Constant_bitrate

   Constant bitrate (CBR) is a term used in telecommunications, relating to the quality of service. Compare with variable bitrate. [1] When referring to codecs, constant bit rate encoding means that the rate at which a codec's output data should be consumed is constant. CBR is useful for streaming multimedia content on limited capacity channels ...

8. Fraunhofer FDK AAC - Wikipedia

   en.wikipedia.org/wiki/Fraunhofer_FDK_AAC

   Fraunhofer FDK AAC is an open-source [5] library for encoding and decoding digital audio in the Advanced Audio Coding (AAC) format. Fraunhofer IIS developed this library for Android 4.1. [6][7] It supports several Audio Object Types including MPEG-2 and MPEG-4 AAC LC, HE-AAC (AAC LC + SBR), HE-AACv2 (LC + SBR + PS) as well AAC-LD (low delay ...

9. Transparency (data compression) - Wikipedia

   en.wikipedia.org/wiki/Transparency_(data...

   It is commonly used to describe compressed data bitrates. For example, the transparency threshold for MP3 to linear PCM audio is said to be between 175 and 245 kbit/s, at 44.1 kHz, when encoded as VBR MP3 (corresponding to the -V3 and -V0 settings of the highly popular LAME MP3 encoder).
