  dcterms:description "Pulse Code Modulated (PCM) is an audio encoding method, originally developed in 1939 for digitally encoding analog signals. It is widely used, including as the default encoding for WAVE and AIFF. PCM is uncompressed by default and uses linear sampling, with various subtypes including µ-law, A-Law, Differential PCM (DPCM), Adaptive PCM (ADPCM), and Linear Pulse Code Modulated (LPCM). Some of these subtypes may be compressed. wHILE PCM is well documented and widely used for encoding, NARA recommends transforming PCM files to BWF." ;
