Rubber Band: Move everything to a DSP class This class can more flexibly process and emit varying chunk sizes than the previous code could, solving the problem of wide tempo changes. Signed-off-by: Christopher Snowhill <kode54@gmail.com> 2025-02-11 05:55:29 -03:00			`//`

DSP: Add thread priority control DSP threads, such as the Rubber Band processing, and planned moves of other processing to buffer threads, such as the Equalizer, FreeSurround, HRTF, and Downmixing for output, because they all have small output buffers. Since these buffers drain and fill fast, they should be processed at a high priority. Hopefully, App Store doesn't complain about the use of these APIs.

Visualization: Reworked buffering system Visualization now buffers in the audio output pipeline, and uses a container system to delay multiple buffer chains from emitting visualization data over top of each other. This should stabilize display output significantly, while introducing minimal lag before DSP configuration changes take effect.
