RESPEAKER.NET

Simple .Net Standard Library to control Respeaker Microphone Arrays.

Dependencies

Uses the Alsa.Net package for audio device communication. Ensure all dependencies are installed on your target system.

First Steps

1. Use the detector to obtain a handle on your device

 using var respeakerDevice = RespeakerDeviceDetector.Detect().First();

2. Read and output device settings

 Console.WriteLine(respeakerDevice.Configuration.ToString());

3. Control the LED ring (set it to red for 5s)

 respeakerDevice.LedRing.Mono(0xFF0000);
 await Task.Delay(5000);
 respeakerDevice.LedRing.Off();

4. Record 15s of audio

 using var tokenSource = new CancellationTokenSource(TimeSpan.FromSeconds(15));
 using var wavStream = new MemoryStream();

 await respeakerDevice.AudioInput.Record(wavStream, tokenSource.Token);

5. Play recorded audio back to the device

 wavStream.Seek(0, SeekOrigin.Begin);
 await respeakerDevice.AudioOutput.Play(wavStream, CancellationToken.None);

Ensure to look into the example projects for more details on how to use this package.
