Struct OutputDeviceParameters

pub struct OutputDeviceParameters {
    pub sample_rate: usize,
    pub channels_count: usize,
    pub channel_sample_count: usize,
}

Available on crate features dep_tinyaudio and alloc only.

Parameters of an output device.

Fields

sample_rate: usize

Sample rate of your audio data. Typical values are: 11025 Hz, 22050 Hz, 44100 Hz (default), 48000 Hz, 96000 Hz.

channels_count: usize

Desired amount of audio channels. Must be at least one. Typical values: 1 - mono, 2 - stereo, etc. The data provided by the call back is interleaved, which means that if you have two channels then the sample layout will be like so: LRLRLR.., where L - a sample of left channel, and R a sample of right channel.

channel_sample_count: usize

Amount of samples per each channel. Allows you to tweak audio latency, the more the value the more latency will be and vice versa. Keep in mind, that your data callback must be able to render the samples while previous portion of data is being played, otherwise you’ll get a glitchy audio.

If you need to get a specific length in seconds, then you need to use sampling rate to calculate the required amount of samples per channel: channel_sample_count = sample_rate * time_in_seconds.

The crate guarantees, that the intermediate buffer size will match the requested value.
