NAudio

timestamped the input buffers, but still getting garbage resampling

fixed the problem with the resampler

Hi, this might be a newbie question but I am banging my head against the wall trying to figure this out..

I have a trackbar and I am playing a song, now I would like to move the trackbar or click in a certain position and have the track play at exactly that point. I have looked around and apparently I use the Mouse_Down events on the trackbar but how do I use the class to play from that same position?

There is a Scroll event which you need to handle, not Mouse_Down. Then you can look at the trackbar value. This is what the NAudioDemo app does, so you can look at its source code.

Mark,

Thanks for the thoughtful reply. I hadn't seen your blog post before. I'll dig into the WinRT project over the next couple of weeks and see if/where I can help.

filtering encode bitrates by sample rate and channel count

Is there a simple way of adding loop utility to wavechannel32 object?

I must use wavechannel32 because I am using pan and volume utilities of wc32.

I have implemented a LoopStream class from waveStream successfully, but I have to use pan and volume properties of wc32.

Which one should I choose in your opinion?

Adding loop (when it lasts, it return to position=0) property to wc32 or adding pan and volume properties to my LoopStream?

Or is there any other way.

NOTE: I do not want to track the position by timer!

encode demo uses MediaFoundationEncoder class

more cleanup of MediaFoundationEncoder and MediaType classes before moving into NAudio

moving MediaFoundationEncoder and MediaType into main NAudio dll. Important: this means we have finally made the conversion from .NET 2.0 to .NET 3.5 to allow LINQ and extension methods

updating resampler to support changing bit depth, channel count and switching between PCM and IEEE float

resampler now can properly drain its buffers on a reposition

resampler now inherits from a generic MediaFoundationTransform base class

MediaFoundationResampler and MediaFoundationTransform moved into main NAudio DLL

With NAudio you build up a pipeline, so you could pass your LoopStream into WaveChannel32 as the source.

adding MediaType and MediaFoundationEncoder to Win8 project, and worked out how to get HResult from COMException in Windows Store apps

I add 2 stream into mixer: first has lenght 1000, second has lenght 2000.

After remove second stream WaveMixerStream32.Lenght = 2000, but should be 1000.

In source code WaveMixerStream32.cs->RemoveInputStream has line:

newLength = Math.Max(length, inputStream.Length)
maybe need replace it with:

newLength = Math.Max(newLength, inputStream.Length) ?

Or I am wrong?

yes, thanks for reporting. That will go in on the next check-in.

Hello,
Here is a modified version of MediaFounfationReader.

Modification for operation with WASAPI, ASIO, WaveOutEvent

I added an option :: The output format (WaveFormat) is PCM or IEEE

Compatible with the version NAudio 569799226a61

This version is still a prototype!
Comments: thanks, these changes will be integrated shortly
