(1.45 bit/sample at 44.1 kHz sampling frequency). Main advantages of OCF are: (1) only a single DSP is needed for decoding; (2) flexible selection of quality (masking threshold) and bit rate is possible. The same decoder can be used to decode 64 kbit/sec. hifi or 128 kbit/sec. studio quality signals.
