Brick f6a4080ff5 audio_resampleLoss: Add support for multiple channels 2023-08-25 08:43:56 -04:00
Brick 4f894e748e audio_resampleLoss: SDL_GetAudioStreamData now returns the correct length 2023-08-25 08:43:56 -04:00
Brick ab83f75bb9 Make sure GetAudioStreamDataInternal is called with a valid length 2023-08-25 08:43:56 -04:00
Brick 6a73f74b6b Rebuild full ResamplerFilter (left wing + right wing) at runtime 2023-08-25 08:43:56 -04:00
Brick 0c15ce0060 Add a missing int cast 2023-08-25 08:43:56 -04:00
Brick b74ee86b1d Optimized ResampleAudio, with special cases for 1 and 2 channels 
This would also benefit from some SIMD, since it's just a bunch of multiply-adds
 2023-08-25 08:43:56 -04:00
Brick fba6e1e3d3 Removed ResamplerFilterDifference 
It takes 1 extra multiply to calculate the correct interpolation,
but I think the improvement in cache locality (and binary size) outweighs that.

Brick 9f7a22fa45 Removed 64-bit handling from AudioConvertByteswap 2023-08-25 08:43:56 -04:00
Brick 1f5327a9fb Removed future_buffer, left_padding, and right_padding from SDL_AudioStream 2023-08-25 08:43:56 -04:00
Brick 71ad52d6db Lowered SDL_GetAudioStreamData to 32 KB 
No particular reason for this number, but 1 MB was a bit silly

emscriptenaudio: Fire the capture silence_callback at an interval. 
Previously it was using setTimeout, not setInterval, so it would only fire
once, which was obviously a mistake.

emscriptenaudio: Don't bother undefining things about to be unreachable. 
Since the top-level table is getting undefined, all the things in it will
be unreachable and eligible for garbage collection without explicitly
nulling them out.

emscriptenaudio: Deal with blocked audio devices better. 
Now, if the AudioContext starts in a "suspended" state, because the browser
blocked it from playing by default, we we run the audio "thread" in a timer
and throw away the generated audio. Once the AudioContext is allowed to
resume, we clear this timer.

The end result is that the app will continue to drain its audio queue
instead of consuming more memory over time (and, if it relies on an audio
callback to make progress, continue to run!), with the effect that the
page is merely silent but otherwise functioning as intended.

Once the user interacts with the page and the browser permits the the
AudioContext to run for real, audio should still be in sync, instead of
just starting to play audio that might now be at least several seconds behind.

Frank Praznik d60ebb06d1 mouse: Ensure that the dummy default cursor is removed from the cursor list 
In the case where a dummy cursor is created as the default cursor, make sure it is removed from the cursor list when freeing the default cursor.

Frank Praznik e58c2731fe mouse: Free the default cursor when destroyed 
The default cursor was being leaked on destruction as it is not in the cursor list, and subsequently SDL_DestroyCursor() wouldn't call the free function for it.

audio: Don't resample in chunks for now. 
This needs a little reworking to not lose sample frames.

Brick c6c1e673c0 Optimized SDL_Convert_*_to_*_Scalar 
They are now all branch-less and avoid float multiplication/conversion where possible
 2023-08-14 15:07:18 -04:00
Brick f97b920b31 Optimized SDL_Convert_*_to_*_SSE2 
Some of the SDL_Convert_F32_to_*_SSE2 do not explicitly clamp the input,
but instead rely on saturating casts.
Inputs very far outside the valid [-1.0, 1.0] range may produce
an incorrect result, but I believe that is an acceptable trade-off.

Frank Praznik 371cc2d173 wayland: Remove unnecessary flag and state settings 
The video core applies pending minimized/maximized/restored state to windows when they transition from the hidden to shown state, so no need to handle it internally anymore.
