- Bit_Rate_Reduction abstract "Bit Rate Reduction, or BRR, also called Bit Rate Reduced, is a name given toan audio compression method used on the SPC700 sound coprocessor used in the SNES, as well as the audio processors of the Philips CD-I and Sony PlayStation. The method is a form of ADPCM.BRR compresses each consecutive sequence of sixteen 16-bit PCM samples into a block of 9 bytes. From most to least significant, the first byte of each blockconsists of four bits indicating the range of the block (see below),two bits indicating the filter (see below), and two bits of control information for the SPC700.The remaining eight bytes consist of 16 signed 4-bit nibbles which correspond to the 16 samples,packed in a big-endian manner. As 32 bytes of input become 9 bytes of output, the BRR algorithm yields a 3.56:1 compression ratio.".
