Brick	edaab8ad9f	Refactored audio conversion to reduce copying ... More of the logic has been moved into SDL_AudioQueue, allowing data to be converted directly from the input buffer.	2024-04-15 11:47:18 -10:00
Brick	ae57b0c9d8	Randomly split the data in audio_resampleLoss ... This helps ensure correct resampling across track boundaries	2024-04-15 11:47:18 -10:00
Brick	8f6f9cadc4	Rewrote audio resampler using cubic filter interpolation ... This allows using a much smaller (1.5 KB) lookup table, in exchange for a small amount of extra work per frame. The extra work (a few extra loads/mul/adds) is negligible, and can execute in parallel. The reduction in cache misses almost certainly outweighs any added cost. The table is generated at runtime, and takes less than 0.02ms on my computer.	2024-04-15 11:47:18 -10:00

Sam Lantinga	ccae9c1ef6	Only initialize audio drivers that have been requested ... If testautomation is running with only a specific audio driver enabled, we shouldn't try to open other ones, as they might fail. Fixes https://github.com/libsdl-org/SDL/issues/8797 (cherry picked from commit 4c11307a4e)	2024-01-08 14:35:42 -08:00

Sam Lantinga	c552cc6847	We don't require the audio system to be initialized for audio format conversion ... This is helpful for tools pipelines where audio devices are never used.	2023-10-11 09:23:23 -07:00

Sam Lantinga	5750bcb174	Update for SDL3 coding style (#6717) ... I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base.
