The sample rate of the incoming digital audio.
The frame rate of the received AES3 format data.
The sample rate of the outgoing digital audio.
The frame rate of the transmitted AES3 format data.
The ratio of the maximum signal level to the noise floor.
The ratio of the noise and distortion to the test signal level. Normally referenced to 0 dBFS.
With an all-zero input, what is the amplitude of the largest frequency component visible with a 16K point
FFT. The value is in dB ratio to full-scale.
The amplitude of jitter on the AES3 stream, or in the ILRCK clock, that will cause measurable artifacts
in the SRC output. Test signal is full scale 9 kHz, Fsi is 48 kHz, Fso is different 48 kHz, jitter is 2 kHz
sinusoidal, and audio band white noise.
With a jitter free OMCK clock, what is the jitter added by the AES3 transmitter.
The difference in amplitude between the output and the input signal level, within the passband of the
digital filter in the SRC.
