Apply the filters on the output devices

[Mitra-M]

Thank you very much for the implementation of the Lowpass, Highpass, Bandpass, and … filters.

Now ,I can apply the filters on the audio files, But I can not apply them on the output devices yet.

How can I do this?

CSCore does not support creating custom audio driver effects. I'm sorry.

I just want to get raw audio data from a device, and manipulate them, and then write them to the device.
I thought it might be possible.

Anyway, thank you.

1-get audio data from an input device
2-filter data (with/without saving data to a file)
3-write filtered data to an output device simultaneously

filoe, please tell me this is possible or not? (using cscore)

Of course that is no problem.
Take a look at the following snippet, demonstrating the basic principle. Just copy paste it into a console app and call Foo():

static void Foo()
{
    //create a new soundIn instance for using input devices
    using (var soundIn = new WasapiCapture(true, AudioClientShareMode.Shared, 30))
    {
        //important: always initialize the soundIn instance before creating the
        //SoundInSource. The SoundInSource needs the WaveFormat of the soundIn,
        //which gets determined by the soundIn.Initialize method.
        soundIn.Initialize();

        //wrap a sound source around the soundIn instance
        //in order to prevent playback interruptions, set FillWithZeros to true
        //otherwise, if the SoundIn does not provide enough data, the playback stops
        IWaveSource source = new SoundInSource(soundIn) {FillWithZeros = true};

        //wrap a EchoEffect around the previously created "source"
        //note: disposing the echoSource will also dispose 
        //the previously created "source"
        using (var echoSource = new DmoEchoEffect(source))
        {
            //start capturing data
            soundIn.Start();

            //create a soundOut instance to play the data
            using (var soundOut = new WasapiOut())
            {
                //initialize the soundOut with the echoSource
                //the echoSource provides data from the "source" and applies the echo effect
                //the "source" provides data from the "soundIn" instance
                soundOut.Initialize(echoSource);

                //play
                soundOut.Play();

                Console.ReadKey();
            }
        }
    }
}

Excellent and perfect.
Wow , I think the cscore has the best and the fastest support in the world.

Thank you so much!

Glad to hear that.
