Found the Wii Crash Noise while using Audacity
I accidentally found out why the Wii makes that buzzing noise when it crashes when I mistakenly created a very small audio loop.
What I think is happening when the Wii crashes:
When the Wii plays audio, it reads samples from an audio buffer. The Wii reads this buffer, front to back, repeatedly. This is normally seamless because the buffer is usually updated with brand-new information by the time the Wii starts to read it again. So what happens if this buffer isn't able to be updated with new sound information, and the Wii continues to read the audio? That is what I assume is happening.
When the Wii crashes, the console doesn't update the buffer with new audio. Nothing tells it to stop reading the audio buffer, so it just reads the same information repeatedly, creating a high-frequency buzz.
Hopefully, I explained that in a way that makes sense.
