AES17 is a standard of the Audio Engineering Society( AES) with the title "Measurement of Digital Audio Equipment". The standard describes the test methods used to specify simple and professional digital audio equipment.
The methods described in AES17 are about measuring jitter in audio systems and building psychoacoustic models with which to predict audio behavior.
As for the jitter measurement of AES17, it is done with a quarter of the sampling rate and a level of -3 dBFS (full scale). If the normal sampling rate is 96 kHz, then the one used in AES17 is 24 kHz. The sampling frequency changes over the audible range between 80 Hz and 20 kHz and is given a jitter of 40 ns. The distortion factor is measured at the amplifier output.
