Replace Core Audio output with Core Media runtime The output now uses AVSampleBufferAudioRenderer to play all formats, and uses that to resample. It also supports Spatial Audio on macOS 12.0 or newer. Note that there are some outstanding bugs with Spatial Audio support. Namely that it appears to be limited to only 192 kHz at mono or stereo, or 352800 Hz at surround configurations. This breaks DSD64 playback at stereo formats, as well as possibly other things. This is entirely an Apple bug. I have reported it to Apple with reference code FB10441301 for reference, in case anyone else wants to complain that it isn't fixed.

Visualization: Make latency animation smoother Compensate for latency by incrementing an offset according to animation frame rate. Signed-off-by: Christopher Snowhill <kode54@gmail.com> 2024-09-21 02:12:50 -03:00			`- (UInt64)samplesPosted;`

Visualization: Increased fft size, imported code Boy, I just be outright stealing code now. But it looks nicer now. Fixes #234 Signed-off-by: Christopher Snowhill <kode54@gmail.com> 2022-02-13 17:15:27 -03:00			`- (void)postSampleRate:(double)sampleRate;`
Fix visualization for variable audio block sizes IN A.D. 2101, WAR WAS BEGINNING. boom Yeah, this was a dumb bug, I didn't realize that AUAudioUnit would just arbitrarily ignore my configured block size and request a different one. The AirPods Pro will just request 480 instead of the 512 I ask for, so let's instead support variable block sizes, and only take up to the last 4096 samples of the chunk fed to the output device.

Code Fix: Add nullability flags to Vis Manager The Visualization Manager PCM/FFT copy function was already observing these parameters for null input and only returning output to the ones which were not null. This just makes it clear that they are both optional parameters. This is useful for future visualization adventures, allowing PCM copy without invoking the FFT processing, or requesting FFT without also having to keep the PCM. This is mostly only a compile time change, and has no noticeable effect on the current runtime behavior, as the only consumers of the Visualizer data currently request both PCM and FFT.

Cleanup: Massive code cleanup and reorganization Cleaned up project settings to current defaults, except for the macOS deployment version, which is still 10.13. Cleaned up a lot of headers and such to include with angle braces instead of double quotes. Enabled build sandbox in a lot of places. Disabled subproject signing in several places, for libraries and frameworks which will be stripped and signed when they are copied into place in the final build. Also, while trying to solve compilation issues, the visualization controller was reverted to the Objective C implementation, which is probably faster anyway. Stupid Swift/Objective-C language mixing issues. Signed-off-by: Christopher Snowhill <kode54@gmail.com> 2025-02-26 01:10:06 -03:00			`- (void)reset;`
