While not an ISO-recognized standard, MPEG-2.5 is widely supported by both inexpensive Chinese and brand-name digital audio players as well as computer software-based MP3 encoders , decoders (FFmpeg) and players (MPC) adding 3 × 8 = 24 additional MP3 frame types. Each generation of MP3 thus supports 3 sampling rates exactly half that of the ...
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.
A lossless audio coding format reduces the total data needed to represent a sound but can be de-coded to its original, uncompressed form. A lossy audio coding format additionally reduces the bit resolution of the sound on top of compression, which results in far less data at the cost of irretrievably lost information.
Media controls on a multimedia keyboard. From top; left to right: skip backward, skip forward, stop, play/pause. Media control symbols are commonly found on both software and physical media players, remote controls, and multimedia keyboards. Their application is described in ISO/IEC 18035. [1]
This could be as simple as a mouse and keyboard or as sophisticated as a piano-style MIDI controller keyboard or automated audio control surface for mixing track volumes. [6] The computer acts as a host for the sound card, while the software provides the interface and functionality for audio editing.
The first update to the Windows PC keyboard in almost 30 years, the Copilot key will be available on laptops and desktop keyboards from Microsoft’s OEM partners beginning in February.

These types of units typically do not have any local storage of their own and must rely on a server, typically a personal computer also on the same network, to provide the audio files for playback. Some MP3 players can encode directly to MP3 or other digital audio formats directly from a line-level audio signal (radio, voice, etc.).
