I am using in my C# winForms application great audio library - NAudio. I am playing sounds by the use of WAVE cache and PlayEngine and i have a question:
Is it possible (and if YES: how?) to play sound with reverb effect with NAudio?
NAudio does not include a reverb effect. It does provide access to the raw audio samples, so you can implement your own effect algorithms. Another option might be to see if there is a Reverb MFT installed and pass the audio through (in the same way that the NAudio MFResampler works).
So the short answer is, unfortunately it's not easy to do.
