Real-time sound output

[larsbrinkhoff]

The sound output is oh-so-close to being ok. I guess there are occasional gaps between audio buffer refills.

I don't know how to fix this, but it can't be rocket science.

[stefanberndtsson]

The current SDL audio output is mostly a hack on top of the previous file output. There is no real coordination between sample generation and sample output, it's just mostly right. Not sure about the state just yet.

[stefanberndtsson]

I removed some crap now. The buffer was previously filled with anything that happened to be in the generated samples array, regardless of whether or not it was generated this pass through the loop or not. The output stream now copies only as much as has been generated, and fills the rest with zeroes. It sounds somewhat better with -V -A now, but still far from perfect.

[larsbrinkhoff]

I'm thinking -A should either:

• imply -V, or something to that effect.
• scale the sound to match the speed of the emulator.

[stefanberndtsson]

Imply -V, definitely. Should it also prevent respeeding (since -V is no longer a locked feature)?

I say, let the users get what they deserve! ;-)
