If I remember correctly, MasterPeakValue is the OUTPUT sample of the mixer. Not the INPUT of a microphone or any other input device.

Rated 5 Stars (out of 5) - I am working on my own little project that gets to the audio using the NAudio library. Just wanted to say "good work and thanks!".

If I understand correctly, in order to achieve a doppler effect in my wav file I have to alter its frequency. In my project with the Naudio library I have implemented a Isampleprovider and have access to the individual samples(float array). What do I have to do now to achieve the doppler effect(change the frequency?). Thanks.

New Post: MediaFoundationReader Error with AIFF file

Hi Guys,
First, cudos to Mark H and the other contributors who did the MediaFoundationReader development. Nice job. And with the addition of HTTPS support, it's making the .Net MediaPlayer look very lame by comparison.


I'm getting the error below on AIFF files. The test file plays fine with standard .Net MediaPlayer class. But MediaFoundationReader blows up. And the same exact code path works fine with Mp3, Wma, and Wav files.
  • Has anyone successfully tested AIFF with MediaFoundationReader ?
error message: The byte stream type of the given URL is unsupported. (Exception from HRESULT: 0xC00D36C4)

   at NAudio.MediaFoundation.MediaFoundationInterop.MFCreateSourceReaderFromURL(String pwszURL, IMFAttributes pAttributes, IMFSourceReader& ppSourceReader)

My code looks essentially like this:
        WaveOut waveOutDevice = new WaveOut()
                {
                    DesiredLatency = 100,
                    NumberOfBuffers = 2,
                };
        WaveChannel32 inputStream = null;
                WaveStream mediaFileReader;
                mediaFileReader = new MediaFoundationReader(fileName); 
                inputStream = new WaveChannel32(mediaFileReader);
                waveOutDevice.Init(inputStream);  <== program gets above exception on this call

Not included in NAudio, you have to code the sample manipulation yourself.

NAudio contains an AiffFileReader class, which you can use alternatively

Hi Freefall, thanks for the reply.
Yeah, I get the same error from the AiffFileReader. So maybe it's something weird about the Aiff file I'm testing with. Or maybe the Klite codec package configuration on my system is blocking aiffs.

New Post: Mid/Side Processing

I am new to this library, and just checked documentation, but couldn't find anything on mid/side channel processing. What I want to do is take a wav file, split it on mid and side channels, then replace the side channel with another mono audio file and finally encode it all together back to wav. Would be even better if I could do all of this with mp3. Any help is appreciated...

Yes, the title: "Waveform using WasapiLoopbackCapture WPF thread updating ui "
WasapiLoopbackCapture dosent draw the waveform on the UI form.
If you are sombody else have a simple sample code that can capture and draw wave form on the UI tthread using WasapiLoopbackCapture it would be very appreciated . But i believe it is not possible.
Thank you

New Post: Counting beeps at start of a WAV file?

I'm totally new to the audio processing area so am hoping this won't be too painful. I need to count a series of beeps at the start of a .wav file and the end time of the last beep in the series. Beeps are 3300Hz and150ms length with a 150ms delay in between. I looked through the SampleAggregator class in the demo but am a bit stumped with what to do with it and what a FFT does. File details below.

Hello: I'm a new member to codeplex, and have a couple of questions about some strange (to me) text in the source code of a couple of the naudio modules. The first anomaly I see is on line 88 of ASIODriverExt.cs. public AsioDriver Driver => driver; I have Visual Studio Team System 2008, which was given to me. I can't afford to upgrade as I'm retired. When I try to compile I get error message about this line of code. There are other anomalies. Anyone care to walk me through a discussion about some of these anomalies? Regards, Karin

NAudio Overview

IMPORTANT The latest NAudio source code can now be found on GitHub. For now, CodePlex remains the place to access documentation, discussions and downloads.

NAudio is an open source .NET audio and MIDI library, containing dozens of useful audio related classes intended to speed development of audio related utilities in .NET. It has been in development since 2002 and has grown to include a wide variety of features. While some parts of the library are relatively new and incomplete, the more mature features have undergone extensive testing and can be quickly used to add audio capabilities to an existing .NET application. NAudio can be quickly added to your .NET application using NuGet.

Thank you for the response .Not quite sure if this discussion was still active. After a bit of tedious research I finally found out what you mentioned.
Related to C# version 6.0 and later versions of .NET. I only have VS2008 so am limited to .NET3.5. Retired and no money to purchase upgrades.
Thanks again. Karin

Trying to figure out how both of these modules are used. Together?? Separately??
I've written a sample program using Rob Philpot's ASIO C++ code. But I need to get away
from the COM issues with Rob's implementation. I recently came across NAudio and it looks
promising. But having difficulties extracting from the Demo stuff how some of the library modules might go together for ASIO streaming. I'm OK with the network part having the working code from my previous effort with Rob Philpot's code embedded in my application. ANY HELPERS OUT THERE???????

I figured out how use these two modules. I've progressed to the point of instantiating the driver successfully, and have created all the necessary hooks, with the exception of the callbacks. I'll start another thread about the use of the callbacks. Karin
