I was experimenting with WasapiOut.cs and found out the minimum supported period is 30000 (30ms). So, I did the following: audioClient.Initialize(shareMode, AudioClientStreamFlags.EventCallback,...

@tommck, what class in NAudio were you using that needed WinForms in Azure?

you must make sure your buffer size is block aligned (use BlockAlign on the WaveFormat). I'm not quite sure what you are referring to as a "frame" in this context.

If it is an ACM codec you must use WaveFormatConversionStream, and if it is a Media Foundation codec you use MediaFoundationReader. It can be a bit of a pain working with custom ACM codecs- you have to...

NAudio gives you access to the raw samples. You'd need to implement your own transient detection algorithm. How simple this is depends on what sort of signal you are looking at. If you can isolate a...

I'm new at audio processing so you will have to forgive my ignorance. I took a look at WaveFormat.BlockAlign. It only has a getter and the value was "4" when I retrieved it (I have been trying to...

That's very strange and unexpected. What sort of a file are you playing? When you say "repeats" forever, do you mean it goes back to the start again? Or does it play silence?

You do need to get the right WaveFormat - using the one from capture should be OK, although WASAPI annoyingly likes to use WAVEFORMATEXTENSIBLE, so often I turn that into the equivalent PCM or IEEE...

What IWavePlayer implementation are you using? The idea is that FileWaveStream's Read method should return 0 when it reaches the end. Then the wavePlayer knows that it can stop playing. So you could...

Hello Mark, thanks for your fast answer. As you suggested, i tried it with WaveFormatExtensible now, which works partially. Partially in the sense that it works sometimes perfectly, but sometimes i...
