Note:
- The full-scale level means the highest output level without clipping.
- The noise-level means the lowest A-weighted noise level at any volume settings.
- The SNR is measured with a -60dBFS sine tone at 997 Hz presenting (AES17).
- The THD+N is the average THD+N between 20Hz and 10kHz at 1/3 octave step (AES17).
- The frequency response is relative value relative to 997Hz (AES17)
- For devices that run at lower than 40kHz sample rate, tests are done only up to near Nyquist instead of 20kHz
