Review of Frequencies and Levels for Digital Audio Performance Measurements
This paper evaluates a wide variety of test frequencies and levels at which digital audio linearity and steady state distortion measurements can be performed. The number of unique codes needed to synthesize the test signals are calculated, and the resulting sensitivity of the sequences to pinpointing DAC random errors are shown.. Test sequences for consumer (CD) equipment operating with 44.1kHz and professional systems using 48kHz sample frequencies are examined.
