Functions
const char *	device_state_to_str (DeviceState state)
	Convert device state to string.

const char *	device_type_to_str (DeviceType type)
	Convert device type to string.

const char *	driver_type_to_str (DriverType type)
	Convert driver type to string.

bool	print_supported (BackendDispatcher &backend_dispatcher, core::IArena &arena)
	Print supported schemes and formats.

Variables
const core::nanoseconds_t	DefaultFrameLength = 10 * core::Millisecond
	Default frame length. 10ms is rather high, but works well even on cheap sound cards and CPUs. Usually you can use much lower values.

Detailed Description

Sound I/O.

Enumeration Type Documentation

◆ DeviceState

enum roc::sndio::DeviceState

Device state.

Enumerator
DeviceState_Active	Device is running and active. It is producing some sound.
DeviceState_Idle	Device is running but is inactive. It is producing silence. It may be safely paused.
DeviceState_Paused	Device is paused. It's not producing anything.

Definition at line 19 of file device_state.h.

◆ DeviceType

enum roc::sndio::DeviceType

Device type.

Enumerator
DeviceType_Sink	Sink.
DeviceType_Source	Source.

Definition at line 19 of file device_type.h.

◆ DriverFlags

enum roc::sndio::DriverFlags

Driver flags.

Enumerator
DriverFlag_IsDefault	Driver is used if no file or device is specified.
DriverFlag_SupportsSource	Driver supports sources (input).
DriverFlag_SupportsSink	Driver supports sinks (output).

Definition at line 39 of file driver.h.

◆ DriverType

enum roc::sndio::DriverType

Driver type.

Enumerator
DriverType_Invalid	Invalid type.
DriverType_File	Driver for audio files.
DriverType_Device	Driver for audio devices.

Definition at line 27 of file driver.h.

Function Documentation

◆ device_state_to_str()

Variable Documentation

◆ DefaultFrameLength

const core::nanoseconds_t roc::sndio::DefaultFrameLength = 10 * core::Millisecond
