PipeWire backend integration uses pw_stream callbacks to process audio buffers for the Singularity synth. The AudioDevicePipeWire component manages this data flow, handling buffer processing and stream lifecycle within the ork.lev2 architecture.

pw_stream callbacks handle real-time audio buffer processing and stream events in the PipeWire backend. They manage the SPA buffer data flow, allowing the Singularity synth to render audio while enabling engineers to track CPU load and diagnose performance issues.

CPU load tracking in the PipeWire backend involves monitoring buffer processing metrics within the stream callbacks. Engineers can observe these metrics in the ork.lev2 implementation files to reason about audio performance and identify bottlenecks during synth playback.

To debug the Orkid PipeWire backend, inspect audiodevice.h, audiodevice_pipewire.h, audiodevice_pipewire.cpp, and config.h under ork.lev2. These files define the AudioDevicePipeWire component, stream callbacks, and configuration flags required for integration.

Yes, integrating the PipeWire backend requires specific configuration flags defined in the ork.lev2 config.h file. These flags enable the AudioDevicePipeWire component and ensure the Singularity synth correctly interfaces with the Linux audio processing model.

SPA buffer processing handles the raw audio data frames within the PipeWire backend's stream callbacks. It defines how buffers are negotiated and passed between the PipeWire server and the Singularity synth, ensuring low-latency audio delivery on Linux.
