Sound recording? Since "dumping frames" has been implemented and all...

[shadowofchaos]

A nifty feature that Dolphin has is that "dump rendered frames" is very useful for recording stuff at a higher resolution than a Dazzle would usually serve for when recording from an actual console.

It is VERY nice, however... the one thing that's missing is the sound timed to the "full speed" of the emulator.

For other emulators for other systems, there was a way to record the sound to the timing of the full speed of the emulated game.

A few examples would be Visual Boy Advance for the GBA, DeSmuME for the DS, and PCSX2 for the PS2. They had some way of recording the sound perfectly, regardless of how good your framerate was while emulating.

Basically, wouldn't dumping the sound as a separate .wav and/or in the avi itself (preferably as a separate .wav file, since dump rendered frames seems to crash for me often on this Windows 7 64-bit laptop) be a good idea to implement into the emulator?

I usually find a way around any crashing issues when dumping frames for emulators, like how my computer crashes the PS2 PCSX2 emulator when recording frames, so I just use the built in sound recorder, and record the screen with FRAPS with the feature "no sync" checked so that the frame rate was a constant 60fps on the video. I just combine the perfect sound recording generated by the emulator, and the perfect video recorded by FRAPS.

But in this case, there's no way to record sound without some sort of lag, despite the perfect frame rate.

I have an idea. If you are somewhat knowledgeable, you can rip the music yourself from the game, and use it as background music.
Or record sound with a sound recorder program while idling;
But I guess you are a 'normal' person : / Go to youtube and download low quality mp3 and use as background.
I know, not what you're asking for, but you can't have everything, huh?

If you've got a fast computer, you could record sound output with Audacity while playing the game. If you're looking to make a video of yourself playing, you can use CamStudio 2.5 to record both video and sound to AVI.
