DefaultAudioScheduler

Class

Source: DefaultAudioScheduler.h

Inherits from: AudioScheduler

Description

Backend-driven scheduler used on platforms without a dedicated audio task.

Delegates all synthesis to ApuCore; generateSamples() runs in whichever context the backend invokes it (tests, simulators without a thread, etc.). Does not own a thread — audio generation is driven by the backend's callback.

For platforms with a dedicated audio task (e.g., FreeRTOS on ESP32), use a scheduler that spawns its own thread instead.
