WAVPCM

WAVPCM refers to a file format that combines the uncompressed audio data of a WAV (Waveform Audio File Format) file with compressed PCM (Pulse-Code Modulation) data. PCM is a standard method for digitally representing analog audio signals, and WAV is a container format that typically holds uncompressed PCM audio. In the WAVPCM context, however, the PCM data within the WAV container has undergone some form of compression.

The exact compression method used within WAVPCM can vary, as the WAV format itself is flexible and can accommodate different audio codecs. This means that while the file might have a .wav extension, the audio data inside is not the raw, uncompressed PCM typically expected. This approach allows for smaller file sizes compared to standard uncompressed WAV files, while potentially retaining a higher fidelity than some other highly compressed audio formats.

The practical implications of WAVPCM are primarily related to storage space and bandwidth efficiency. However, playback compatibility can be a concern, as standard audio players might not recognize or be able to decode the specific compressed PCM stream within the WAV container. Specialized software or hardware that supports the particular compression codec used would be necessary for proper playback. This format is less common than standard uncompressed WAV or widely adopted compressed formats like MP3 or AAC.
