PS1 Digital Audio Adapter - Audio Test

This is a short audio test using the PS1 Digital Audio Adapter on the SCPH-5501 model.

- You can purchase one of these adapters here: https://www.tindie.com/products/theretrochannel/playstation-ps1-digital-audio-adaptor/
- Note: Requires two wires to be soldered on the main board for it to work. It is a no-cut solution for optical audio and is an easier install than other solutions.

- Key finding: Any PS1 has some cross-talk introduced at the console end, occurring at about the 15.5 kHz frequency regardless of what cable you use. With this Digital Audio Adapter, you can eliminate this cross-talk from the audio entirely. In this audio test, the only noise you hear is when the noise exists in the original recording in the game itself. There is no noise floor at all. The audio is much clearer and pairs well with high-end audio equipment.

- Side-note for analog audio: If you do use cheap A/V cables, the original analog audio can worsen the cross-talk audio buzz. Higher end cables from Retro-Access or HD Retrovision will keep this as low as possible where the noise floor is hardly noticeable. You can refer to my previous audio test here for a handful of cable comparisons: https://rumble.com/v3cde2g-scart-cable-audio-test-update.html

Console: PlayStation (SCPH-5501)
Cable (video): Retro-Access PS1 RGB SCART Sync-on-Luma
Cable (audio): Sys. Concept MiniPlug to Toslink Premium Optical Cable (M2TX)
Scaler: RetroTink 4K
Capture Card: TUF GAMING CAPTURE BOX-4KPRO

- Recorded directly with OBS. This video also doubles as a test of OBS's ability to resample 44.1 kHz source audio into 48 kHz. (The PS1 Digital Audio Adapter outputs PS1's native 44.1 kHz audio.)
The RetroTink 4K will passthrough digital audio at the same sample rate as the source.
I did not find any audio artifacts in OBS's resampling.

**Re-upload note: This is a re-record. I have taken down the previous version of this video. I turned off Auto Dec. Phase on the RT4K that was causing the video to shift left and right. I also swapped out the disc drive on the PS1 to improve FMV playback and loading.
