32kHz sample rate

Using MDFourier 1.07d (15-12-2021) with this reference file.

The 32kHz sample rate is most commonly used by licensed software. It is upsampled to 48kHz in hardware prior to final output.

A 15kHz white screen was displayed to induce audible noise.

48kHz sample rate

Using MDFourier 1.07d (15-12-2021) with this reference file.

The nominal sample rate is 54MHz÷1124, rather than 54MHz÷1125. This is reflected in the frame duration of the standard equipment test.
The 48kHz sample rate is most commonly used by homebrew software and streaming audio in licensed software.

A 15kHz white screen was displayed to induce audible noise.
