High resolution audio recording and playback formats have been available to the professional and individual user for years. Consumers are able to create and listen to digital audio captured well in excess of the traditional “CD-Quality” 44KHz, 16-bit standard released back in 1982. While debate continues as to the audibility of the additional information these systems capture, these formats are caught up in a relatively new spec-war that is driving the need to test beyond the traditional limits of 96dB at 44kHz. This presentation will explore the performance of the native instruments in the ETS-800 for these higher levels, as well as describe techniques at the DIB and software level to extend the performance of these instruments. Techniques to be explored include bandpass filtering the source waveform, notch filtering and gain to measure low amplitude harmonics, and using the built in gain of the SPU-8112 to measure lower noise floor.
