Struct sphinxad::AudioDevice

pub struct AudioDevice { /* fields omitted */ }

Audio device like microphone It will automatically stop recording and will be destroyed

Methods

impl AudioDevice

fn default() -> Result<AudioDevice>

Open default audio device(microphone) with SPS(samples per second) = 16000

fn default_with_sps(samples_per_second: usize) -> Result<AudioDevice>

Open default audio device(microphone) with given SPS

Example

use std::thread;

let mut device=AudioDevice::default_with_sps(44100)?;
device.start_recording()?;

loop{ //recording loop
    match device.read(&mut buffer[..])? {
        Some( buffer ) => {
            for i in 0..buffer.len() {
                ...
            }
        },
        None => break,
    }

    thread::sleep_ms(100);
}

fn with_name_and_sps(
    name: &str,
    samples_per_second: usize
) -> Result<AudioDevice>

Open specified audio device with given SPS

fn start_recording(&mut self) -> Result<()>

Start recording

fn stop_recording(&mut self) -> Result<()>

Stop recording

Example

let mut device=AudioDevice::default_with_sps(44100)?;
device.start_recording()?;

loop{ //recording loop
    ...
}

device.stop_recording()?;

thread::sleep_ms(1000);

device.start_recording()?;

fn read<'a>(&self, buffer: &'a mut [i16]) -> Result<Option<&'a [i16]>>

Read sound to buffer, and return slide of read samples(length of slice may be not equal to buffer length). Return None if nothing to read
