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

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

== Conclusions ==
* Unless your hearing above 8kHz is shot, the Bitfunx/Kaico GameCube Component Cable and Retro-Bit Retro Prism Component Cable will sound dramatically different from anything else.
** Due to a firmware bug, their effective sample rate is 24kHz.
** No audio frequencies above 12kHz can be reproduced, and content above 12kHz is aliased into lower frequencies.
** The audio from these cables is not recommended for use with [[Game Boy Interface]] due to excessive aliasing.
** The red audio cable is the left channel, and the white audio cable is the right channel.
* Unshielded audio/video cables will induce 15kHz noise.
* GCVideo-DVI's Sample Rate Hack is an option of last resort.

32kHz sample rate

Using MDFourier 1.08 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.

96kHz sample rate

The 96kHz sample rate is an unused feature intended for playback of DVD-Audio.
The nominal sample rate is 54MHz÷562, rather than 54MHz÷562.5.

Conclusions

  • Unless your hearing above 8kHz is shot, the Bitfunx/Kaico GameCube Component Cable and Retro-Bit Retro Prism Component Cable will sound dramatically different from anything else.
    • Due to a firmware bug, their effective sample rate is 24kHz.
    • No audio frequencies above 12kHz can be reproduced, and content above 12kHz is aliased into lower frequencies.
    • The audio from these cables is not recommended for use with Game Boy Interface due to excessive aliasing.
    • The red audio cable is the left channel, and the white audio cable is the right channel.
  • Unshielded audio/video cables will induce 15kHz noise.
  • GCVideo-DVI's Sample Rate Hack is an option of last resort.
