Project PDA

It is not very common among some PDA, such as Palm, include an audio system. In general, PDAs have a microphone and loudspeaker; enabling recording voice notes or listens to audio files such as MP3. The MP3 playback superiority will depends on the small piece rate of the audio file and the quality of the incorporated speaker. The audio quality is frequently enhanced when played back throughout an eminence headset.

Windows Media Audio (WMA) is a proprietary compressed audio file format developed by Microsoft. It was initially intended to be a competitor to the popular MP3 format, though in terms of popularity of WMA files versus mp3 files, this never came close to occurring. However, with the introduction of WMA Pro and Apple's iTunes Music Store, WMA has positioned itself as a competitor to the Advanced Audio Coding format used by Apple and is part of Microsoft's Windows Media framework.

A large number of consumer devices, ranging from portable hand-held music players and handphones to set-top DVD players, support the playback of WMA files.
