Emulator Issues #4552
DSPHLE's audio dumper mangles output audio
What's the problem?
When listening to the output audio after dumping an audio sample, the timing of sounds and music is off, making it impossible to use the audio stream for anything. This changes the timing of audio events, making it impossible to be used with accompanying video dumps because of bad audio/video desync.
Dolphin version with the problem (as it appears in the title bar, Ex.: "R
4779" or "R 6403M"):
(optional) Dolphin version that does not have the problem:
Operating system and version:
32-bit or 64-bit:
WinXP Pro MCE x86
Game ID (as it appears in game properties, Ex.: "GZ2P01" or "RSBE01"):
Build command-line (not on Windows):
Was the ISO a plain dump from disc, compressed and/or scrubbed?
Please provide any additional information below.
Here's a sample of the Mario Kart Double Dash theme music. The first sample you hear is from the Gamecube, the second one is from Dolphin. Please note that during real time emulation the music sounds just fine, it's only when playing back recorded audio from DSPHLE that the problem starts.

I'd say HLE audio emulation is "barely supported nowadays", not that HLE is "no longer supported".
But still, in games such as NSMBW or SMG, non-sequenced (pre-rendered) music is usually played at the same "speed" regardless of VPS, as opposed to sequenced noises/music. Thus, when dumping into full speed, you won't get the same accuracy with HLE audio rendering (wherein sounds tend to be desync'd) than with LLE.
