Though a WAV file can contain compressed audio, the most common WAV audio format is uncompressed in the linear pulse code modulation (LPCM) format. For example, an MP3 file created using the setting of 128 kbit/s will result in a file about 1/11 the size of the CD file created from the original audio source. Lossy compression is designed to reduce significantly the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. The usual bitstream encoding is the linear pulse-code modulation (LPCM) format. It is the main format used on Windows systems for raw and typically uncompressed audio. Waveform Audio File Format is a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs. It is a common audio format for consumer audio streaming or storage and a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players. MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio that uses lossy data compression. Audio/vnd.wave, audio/wav, audio/wave, audio/x-wav
