How to apply Equalizer to soundInSource created by WASAPICapture or WASAPILoopbackCapture? #381

Closed JohnsonGao closed 5 years ago

JohnsonGao commented 5 years ago

Hi Florian, I can play the captured stream now, but failed to append an Equalizer for the SoundInSource, So where is the problem for this? How should I apply EQ to a captured stream? Codes here but it doesn't work. Thanks a lot!

var _soundInSource = new SoundInSource(_soundIn) { FillWithZeros = true };

_soundInSource
.ToSampleSource() .AppendSource(Equalizer.Create10BandEqualizer, out _equalizer) .ToWaveSource();

var soundOut = new WasapiOut(); soundOut.Initialize(soundInSource); soundOut.Play();

Hi @JohnsonGao, you have to initialize the soundOut with the result of the whole chain. That means:

IWaveSource source = _soundInSource
.ToSampleSource()
.AppendSource(Equalizer.Create10BandEqualizer, out _equalizer)
.ToWaveSource();
...
soundOut.Initialize(source);
