[Apple II/e] Disk Drive Sound causes continuous high-pitch audio

[vanfanel]

Hi there,

I noticed that the high-pitch audio I was hearing with this core comes from having the DISK DRIVE SOUND option active.
Maybe it should be reported in github as a bug? It's truly ear-piercing and I don't think real Apple II disk drive produced that awful sound

it's more of a white noise than high pitch...
But I suppose everybody has different hearing, what I can do for now is disable it by default.

Real disks had a kind of white noise sound while spinning.What's in the core is an approximation and is supposed to no be very loud.

@newsdee: It has a high-pitch component for sure: it's mostly white noise, but there's also the high freq pitch, similar to what some CRTs used to emit.

Other thank thank, disk drive sound is a FANTASTIC addition, really!

Do you mean you will be disabling the "noise" part by default, or the whole disk drive sound altogether?

It depends. I want to be careful not to add too many options.

That noise you refer to is the "disk spinning" sound;
I can try to disable it separately but (to me) it adds a lot to the experience... without it the floppy sounds like a hard drive.

Ah, the disk spinning makes a lot of sense, of course. No need for an option or anything, just... what do you use to produce that spinning sound? If you open that waveform with an editor, I'm sure you will see the high pitch even if you can't hear it.
So maybe that high pitch component can be eliminated.

So I've finally had time to get back to test this... and you are completely right.
It is actually very blatant if I use headphones and I can't believe I didn't think of testing this setup

Right now I don't have a way to fix it, so I will remove the feature altogether in the main repo.
I may revisit it one day but I don't want to burden another dev with fixing it.

Thanks for testing it and for your feedback.

Oooh!! Bad news!!! It was a nice improvement.
