bitrate
because of the low tape speed, the achievable bit rate of dcc is limited. to compensate, dcc uses precision adaptive sub-band coding (pasc) for audio data compression. pasc was later integrated into the iso/iec 11172-3 standard as mpeg-1 audio layer i (mp1). though mp1 allows multiple bit rates, the bit rate of pasc is fixed at 384 kilobits per second, resulting in 114.84375 frames per second. when the sample frequency is 44100 samples per second, not all frames contain the same amount of data: about 49% of the frames only contain 416 bytes of data, but all frames on tape are 420 bytes so the effective data rate is 384 kbit/s exactly. mp1/pasc uses digital filters to divide the audio into 32 frequency subbands, and then uses adaptive allocation and scaling to decide how many bits should be assigned to represent each frequency band. when decoding, the subband bit stream is used to synthesize an uncompressed bit stream again. pasc lowers the bitrate of a cd recording of approximately 1.4 megabits per second to 384 kilobits per second, a compression ratio of around 3.68:1. the difference in quality between pasc and the 5:1 compression used by early versions of atrac in the original minidisc is largely a subjective matter.
