Disclosures

  • EON GCHD Mk-II was provided by EON Gaming.
  • HD Retrovision SNES Component Cable was provided by HD Retrovision.
  • Insurrection Industries CARBY was provided by Insurrection Industries.
  • Retro-Bit Retro Prism Component Cable was provided by CastleMania Games.
  • RetroTINK-5X Pro was provided by RetroTINK.

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.
The nominal sample rate is 54MHz÷1124, rather than 54MHz÷1125. This is reflected in the frame duration of the standard equipment test.

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

ASUS PRIME X570-PRO

Using ALC1220 (S1220A).

This sound card serve as our analog reference.

48kHz sample rate

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

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

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