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.

I know this is a long shot, and very difficult, maybe even impossible to do. But I'm going to ask it anyway.
Is there any way to keep .NET's SpeechRecognitionEngine (SAPI) from hearing or recognizing the audio coming from computer speakers, without using an external microphone.
An example would be
Playing a YouTube video, or song, and not of the Recognizer
listen to the audio form that video or song Or at least not recognize it as speech
Thanks
In theory if you have an internal audio source like the YouTube video and want to exclude that from things processed by an internal microphone, you can invert the audio signal from that source and use it to cancel out the same sound picked up via the microphone. That is how noise cancelling headphones work. I have no idea whether that is possible with SAPI – Eric J.
While implementing this would take to long for me, this seems like the most do-able and reasonable answer.
Hi I Want to Decrease the Compression rate/Playing Speed of My Audio Tracks in C# Using NAudio class, i.e. I want tracks to play at a slower speed than their original speed.
Previously I was using Windows Media Player object for just this thing and NAudio for everything else, but I want to shift completely to NAudio.
NAudio does not have a built-in feature to do this. When I need to change playback rate, I create a managed wrapper around the SoundTouch dll. I keep meaning to blog about how to do this, but for now, check out the PracticeSharp project which also uses SoundTouch and NAudio.
Need to record all sounds from sound card. So that mic+output was written to file.
Is it possible to do with NAudio library in Windows 7? Cant find any examples, found just ones that allow to write mic or just sound from speakers, not both.
PS, sorry, if the question looks not ok..Im new to audiorecording.
Added issue ive asked on codeplex: http://naudio.codeplex.com/workitem/16353
To record sounds being played by the soundcard, you would use WASAPI in Loopback Mode.
To record sounds going into the microphone you could use WASAPI capture, or any of the other microphone capture classes in NAudio.
Then you have the slightly tricky job of mixing those two inputs together. This may require sample rate conversion beforehand, and it may require you to timestamp the recorded audio (as the loopback audio can contain gaps when nothing is being played).
With NAudio, you would convert both streams to floating point, before mixing them using one of the "Mixer" wave or sample providers in NAudio, and then writing that back out to a file.
So yes it is possible, and I have done it once before myself, but it does require you to write a fair bit of your own code on top of the core NAudio libraries.
I want to capture sound from mic and play it again in speakers in c# but not using Microsoft.DirectX.directsound how?
As an alternative to DirectSound there are the multi-media APIs. I know of no binding that's included with .net, but there are several third party bindings of varying quality.
naudio is a popular .net audio library, but I don't know which API it uses in the background. As long as you avoid the abomination called WaveBuffer you should be fine.
In my project I used Lumisoft.Audio, mainly because it has a simple API. But their code doesn't have a very high quality.
As CodeInChaos mentions NAudio (http://naudio.codeplex.com/) will do the trick. Here is an article from channel 9, which hopefully will help you out:

Is it possible to use the NAudio on a silverlight application?
I just can't add the dll to my project... I'd like to build a little audio mixer.
I already searched on google but i can't find a way to do that...
someone has some hints for it???
NAudio uses tons of interop into Win32 functions that would be completely impossible to run in Silverlight.
UPDATE:
If you are looking for an MP3 player for Silverlight you may check out the Silverlight Audio Player.
