Apple and Microsoft support the ISO/IEC-defined formats AAC and the older MP3. Mozilla and Opera support the free and open, royalty-free Vorbis format in Ogg and WebM containers, and criticize the patent-encumbered nature of MP3 and AAC, which are guaranteed to be “non-free”. Google has so far provided support for all common formats.
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.

Various software, firmware, and hardware components may add up to a substantial delay associated with starting playback of a track. If not accounted for, the listener is left waiting in silence as the player fetches the next file (see harddisk access time), updates metadata, decodes the whole first block, before having any data to feed the hardware buffer.
