WAV files header

RIFF/WAV is a header type added to standard MPEG Layer-3 audio files. This enables them to be played by the Windows version of The Palace Stand-alone Client program, which will only play sound files with a RIFF header.
The RIFF header marks the file as WAVE data with the audio parameters as determined from header of the MP3 file. The format tag specifies that the data should be handled by the Fraunhofer MPEG Layer-3 Audio Codec, which must be installed on the computer running the Palace Client.
Another limitation of the Windows Palace Client is that it will not play audio files with more than about one megabyte of data. The actual limit is close to 1,134,000 bytes. The Palace Client seems to use the length of the data as specified in the RIFF header as opposed to actual size of the file, itself. Unless directed otherwise, riffmp3 limits the size specified in the RIFF header but includes all of the actual MP3 data. With this size limit, an MP3 file with a sample rate of 48 Kbits pre second can play a song about 3 minutes in length.

MP3 files with RIFF headers will play on most normal MP3 players and media programs. They ignore the RIFF header and play the MP3 audio data in its entirety. Programs such as WinAmp, QuickTime Player (on both Windows and Macintosh) and SoundApp (for Macintosh) are examples of MP3 players that will play the full MP3 data. One notable exception is the Microsoft Windows Media Player. Although it will play MP3 files with the RIFF header, it uses the same system codec as the Palace. Therefore it will only play the amount of data specified in the RIFF header and ignore the remaining MP3 data.

RIFF-WAV header

The output file is written as a RIFF-WAV file. This means that there is stored an additional header (a so called RIFF-WAV header) at the beginning of the encoded file. Furthermore, the extention becomes .WAV. If you have installed a Windows Codec to decompress MP3 Files, this option might be useful. Since Windows takes care of the decompression, even applications that are not aware of the MP3 format can handle this file fromat via the Windows Codec.
