MPEG-2 Part 3 also enhanced MPEG-1's audio by allowing the coding of audio programs with more than two channels, up to 5.1 multichannel. [ 26 ] The Layer III ( MP3 ) component uses a lossy compression algorithm that was designed to greatly reduce the amount of data required to represent an audio recording and sound like a decent reproduction of ...
Audio file icons of various formats. 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.
Each generation of MP3 thus supports 3 sampling rates exactly half that of the previous generation for a total of 9 varieties of MP3 format files. The sample rate comparison table between MPEG-1, 2, and 2.5 is given later in the article. [63] [64] MPEG-2.5 is supported by LAME (since 2000), Media Player Classic (MPC), iTunes, and FFmpeg.

The first WMA codec was based on earlier work by Henrique Malvar and his team which was transferred to the Windows Media team at Microsoft. [5] Malvar was a senior researcher and manager of the Signal Processing Group at Microsoft Research, [6] whose team worked on the MSAudio project. [7] The first finalized codec was initially referred to as ...
Hardware audio codecs send and receive digital data using buses such as AC'97, SoundWire, [5] I²S, SPI, I²C, etc. Most commonly the digital data is linear PCM, and this is the only format that most codecs support, but some legacy codecs support other formats such as G.711 for telephony.
Office Mix did not come embedded into the PowerPoint program. Instead, the user had to obtain the Office Mix add-in installer through the mix.office.com website in order to integrate the Office Mix add-in to the PowerPoint program and a global tab named "Mix" would appear across the application's interface where the user could access various options related to Office Mix.
