- channels
The channel count of the device.
- distance_model
The distance model of the device.
See also
- doppler_factor
The doppler factor of the device. This factor is a scaling factor for the velocity vectors in doppler calculation. So a value bigger than 1 will exaggerate the effect as it raises the velocity.
- format
The native sample format of the device.
- listener_location
The listeners’s location in 3D space, a 3D tuple of floats.
- listener_orientation
The listener’s orientation in 3D space as quaternion, a 4 float tuple.
- listener_velocity
The listener’s velocity in 3D space, a 3D tuple of floats.
- lock()
- classmethod lock()¶
Locks the device so that it’s guaranteed, that no samples are read from the streams until
unlock()is called. This is useful if you want to do start/stop/pause/resume some sounds at the same time.Note
The device has to be unlocked as often as locked to be able to continue playback.
Warning
Make sure the time between locking and unlocking is as short as possible to avoid clicks.
- play()
- classmethod play(sound, keep=False)¶
Plays a sound.
- Parameters
sound (
Sound) – The sound to play.keep (bool) – See
Handle.keep.
- Returns
The playback handle with which playback can be controlled with.
- Return type
Handle
- rate
The sampling rate of the device in Hz.
- speed_of_sound
The speed of sound of the device. The speed of sound in air is typically 343.3 m/s.
- stopAll()
- classmethod stopAll()¶
Stops all playing and paused sounds.
- volume
