Detailed Description

Threaded mock hardware audio interface for integration tests.

Runs audio callbacks in a background thread to simulate real audio device behavior, required for tests that need to process audio asynchronously.

Member Function Documentation

add_audio_callback()

void zrythm::test_helpers::ThreadedMockHardwareAudioInterface::add_audio_callback ( dsp::IAudioCallback * callback )

inlineoverridevirtual

Adds an audio callback to receive audio I/O events.

The caller must ensure callback remains alive until after remove_audio_callback() is called with the same pointer.

Implements zrythm::dsp::IHardwareAudioInterface.

Definition at line 70 of file mock_hardware_audio_interface_threaded.h.

get_device_info()

dsp::AudioDeviceInfo zrythm::test_helpers::ThreadedMockHardwareAudioInterface::get_device_info ( ) const

inlinenodiscardoverridevirtual

Returns the current audio device information.

Guaranteed to return up-to-date values during about_to_start() callbacks.

Implements zrythm::dsp::IHardwareAudioInterface.

Definition at line 42 of file mock_hardware_audio_interface_threaded.h.

process_call_count()

std::size_t zrythm::test_helpers::ThreadedMockHardwareAudioInterface::process_call_count ( ) const

inlinenodiscard

Returns the number of times process_audio has been called.

Thread-safe: can be called from any thread (e.g., the test main thread) while the audio callback thread is running.

Definition at line 65 of file mock_hardware_audio_interface_threaded.h.

remove_audio_callback()

void zrythm::test_helpers::ThreadedMockHardwareAudioInterface::remove_audio_callback ( dsp::IAudioCallback * callback )

inlineoverridevirtual

Removes a previously added audio callback.

callback must be the same pointer passed to add_audio_callback().

Implements zrythm::dsp::IHardwareAudioInterface.

Definition at line 85 of file mock_hardware_audio_interface_threaded.h.

set_device_info()

void zrythm::test_helpers::ThreadedMockHardwareAudioInterface::set_device_info ( dsp::AudioDeviceInfo info )

inline

Updates the device info.

Must not be called while audio processing is active (between about_to_start() and stopped()).

Definition at line 53 of file mock_hardware_audio_interface_threaded.h.

simulate_device_change()

void zrythm::test_helpers::ThreadedMockHardwareAudioInterface::simulate_device_change ( dsp::AudioDeviceInfo new_info )

inline

Definition at line 97 of file mock_hardware_audio_interface_threaded.h.
