The most recent version of OCF (Optimum Coding in the frequency domain) allows coding to 64 kbit/sec. (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 hi-fi or 128 kbit/sec studio quality signals.
