Struct AudioInput 

pub struct AudioInput { /* private fields */ }

The audio input device and stream configuration used for recording.

The caller must be certain that the config works for the given device on the current platform; AudioInput::default_device and AudioInput::from_device pick configs that do.

Implementations

impl AudioInput

pub fn default_device() -> Result<Self, Error>

Uses the system default input device with its default configuration.

pub fn from_device(dev: Device) -> Result<Self, Error>

Uses the given device with a mono input configuration if it offers one, otherwise with its default input configuration.

Everything is visualized as mono anyway, so recording mono directly halves the data the device has to deliver and saves the downmix. For a device that only offers stereo, recording averages the two channels.

pub const fn new(dev: Device, cfg: StreamConfig) -> Self

Uses the given device and stream configuration.

A buffer_size of cpal::BufferSize::Default does not mean the device default: recording then asks for 256 frames per callback, which keeps the visualization moving every frame on high refresh rate displays, and only falls back to the device default if the device rejects that. A fixed size is used as given.

pub fn devices() -> Result<Vec<(String, Device)>, Error>

All available input devices of the default host, sorted by name.

pub const fn device(&self) -> &Device

The input device.

pub const fn config(&self) -> &StreamConfig

The stream configuration.
