DeviceCaps

class carb.audio.DeviceCaps

Bases: pybind11_object

Contains information about a single audio input or output device. Note that this information should not be stored since it can change at any time due to user activity (ie: unplugging a device, plugging in a new device, changing system default devices, etc). Device information should only be queried just before deciding which device to select.

Methods

__init__(*args, **kwargs)
get_name(self)	A UTF-8 string that describes the name of the audio device.

Attributes

channels	The preferred number of channels of data in each frame of the audio data.
flags	unplugging a device or switching system defaults).
format	The preferred format of each sample of audio data.
frame_rate	the way it was recorded or produced).
guid	A GUID that can be used to uniquely identify the device.
index	plugging in or removing a device from the system).

__init__(*args, **kwargs)

get_name(self: carb.audio._audio.DeviceCaps) → str

A UTF-8 string that describes the name of the audio device. This will most often be a ‘friendly’ name for the device that is suitable for display to the user. This cannot be guaranteed for all devices or platforms since its contents are defined by the device driver. The string may have been truncated if it was too long.

property channels

The preferred number of channels of data in each frame of the audio data. Selecting a device using a different format than this will result in extra processing overhead due to the format conversion.

property flags

unplugging a device or switching system defaults). This may be 0 or any combination of the `DEVICE_FLAG*` flags.

Type

Flags to indicate some attributes about this device. These may change at any time due to user action (ie

property format

The preferred format of each sample of audio data. This is given as a symbolic name so that the data can be interpreted properly. Selecting a device using a different format than this will result in extra processing overhead due to the format conversion.

property frame_rate

the way it was recorded or produced). Selecting a device using a different frame rate than this will result in extra processing overhead due to the frame rate conversion.

Type

The preferred number of frames per second that must be played back for the audio data to sound ‘normal’ (ie

property guid

A GUID that can be used to uniquely identify the device. The GUID for a given device may not be the same from one process to the next, or if the device is removed from the system and reattached. The GUID will remain constant for the entire time the device is connected to the system however.

property index

plugging in or removing a device from the system). When a device is added to or removed from the system, the information for the device at this index may change. It is the caller’s responsibility to refresh its collected device information if the device list changes. The device at index 0 will always be considered the system’s ‘default’ device.

Type

The current index of this device in the enumeration order. Note that this value is highly volatile and can change at any time due to user action (ie
