this means you have no ACM codecs installed on the computer that can decode that particular codec.

New Post: Clipping wrap-around
what bit depth are you saving your WAV files in? If its floating point, no clipping is necessary at all. If its 16 bit, then your audio has to get coerced into the range supported by an Int16

yes, that will work, but remember that many ASIO drivers will not let you open multiple instances of the same sound card.

New Post: Stereo Pairs
Yes. Because disposing of these objects is still confusing to me (the how and when) and also because my app will only ever play one file at a time anyway, I moved the instancing to the form level to only ever user the one instance of those things across the board, and dispose of them all on form close. I just need to do it all without ever calling anything else as "New" that needs additional disposal.
Public Player = New WaveOutEvent()
Public wave As NAudio.Wave.WaveFileReader
Public output As NAudio.Wave.AsioOut↧
New Post: Clipping wrap-around
My app saves them back into the same format it loaded them in. In these recent cases, this has been 24bit files. How do I save to floating point? I didn't even know there was such a thing as a floating point WAV file.

New Post: The requested address is not valid in its context
Before to try develop a voice chat with your sample (Network Chat), I decided to test it before.
On IPAdress, if I put 127.0.0.1 or my own IP, it works fine. But if I put a IP from any computer. It sends me back: "The requested address is not valid in its context".
Now the question: The sample code is ready for connect with another computer? Or only the Server IP?

Or in other words: you´d have to decode the file yourself or by an extra library.

New Post: An Event to Fire to Dispose?
I´d suggest you subscribe to the PlaybackStopped Event and dispose there.

New Post: An Event to Fire to Dispose?
Thanks. I think I have it sorted. If you don't mind, look over this code and tell me if you think there are any memory leaks or potential issues there.
I playback the audio with this class code below. Because my app is triggering really short files it uses shared public vars for the object references to track and dispose of them on every trigger cycle and to also allow the main form to dispose of any leftover objects on quit, like if a user hit the quit the application while audio was playing. Not sure if the PlaybackStopped event would trigger in that case.
Also, looking at volume, it appears to be obsolete, I need another way.

New Post: Clipping wrap-around
You can save a WAV file in any WaveFormat. What's converting back to 24 bit then?
↧
New Post: Clipping wrap-around
I just use the same WaveFormat object that I loaded the WAV file from. I'm just doing a few basic effects so the total samples doesn't change or anything. I looked up floating point and it seems I found my answer: 32bit is floating point.

NAudio has wrappers for many parts of the WASAPI Core audio interfaces. The best place to learn about them is actually MSDN.

New Post: Network chat between regular C# and Raspberry Pi 2 using NAudio
first, you're likely capturing stereo audio, so the volume of data sent will be very high. I'd also try to find ways to reduce the volume of audio being sent. IEEE float at 44.1kHz is not very efficient.
Why not start by capturing the audio to a WAV file, and saving a few seconds. This might highlight any mismatches of WaveFormat.

New Post: AAC encode to stream
I'm wondering whether anyone has an example of using a Media Foundation Transform to encode AAC to a stream as opposed to a file?
I found this thread from a couple of years back which seems to suggest that it's possible but, looking at the creation of a custom MFTransform was enough to give me a headache and looks like it'd involve quite an indepth knowledge of Media Foundation which I don't reallly have!
Any help would be gratefully recieved.
Thanks,
Kenny
