Currently IвЂ™ve got a derived MediaFoundationReaderRT class in the demo, which allows you to open files from an IRandomAccessStream.

The main difference is the way you read and write files in Windows Store apps.

IвЂ™m also working on adding Windows Store support for. This also is hugely beneficial to supporting playback and recording with WASPI in Windows Store applications since the DMO interface which the existing WASAPI support uses is not allowed. The resampler in Media Foundation is reasonably good quality and can also change the bit depth and channel count, making it a very useful general purpose class. MediaFoundationResampler The most useful of all the media foundation effects, and based on MediaFoundationTransform, which you can use to wrap other effects if needed.It is also extensible enough to let you use any other encoder you have. This class includes helper methods for encoding WMA, MP3 and AAC (assuming you have the encoders), and all you need to do is supply the output filename, the PCM source stream and the desired bitrate. MediaFoundationEncoder I wanted to make encoding as simple as possible, and IвЂ™m quite pleased with the API I came up with (you can read a bit about it here).It uses Media FoundationвЂ™s support for repositioning which so far looks pretty good (although it might not get to exactly the point you asked for), and can even reposition in MP3 files you are downloading from the internet. It also tries to hide the very awkward problem of COM apartment state issues from you by (optionally) recreating the Media Foundation source reader in the first call to Read (as that might come from an MTAThread). The output of MediaFoundationReader will always be PCM, so no second converter step is required. It may be that this class becomes the primary way of playing audio for NAudio going forwards. It can even pull the audio out of video files. This means MP3, AAC, WMA, WAV, and includes streaming from the internet. MediaFoundationReader this implements WaveStream and basically allows you to play anything that Media Foundation can play.NAudio 1.7 will have the following three main classes to support Media Foundation:

I have now done enough to enable the three main uses of Media Foundation вЂ“ encoding, decoding and resampling.

There was a lot of interop code required to get Media Foundation working, and with the help of a few people (most notably ManU from the Codeplex forums).

Windows 8 even comes with an MP3 encoder. The second is simply that Media Foundation is the future for audio codecs in Windows, and includes some codec support that ACM doesnвЂ™t offer, such as AAC encode and decode. This was the impetus I needed to finally get round to wrapping Media Foundation API, having been put off by the thought of wrapping yet another large COM-based API. The first is that Windows Store apps can use Media Foundation but cannot use ACM or DMO, which were the two codec APIs that NAudio did support.

IвЂ™ve been working on adding Media Foundation support to NAudio 1.7 over the past few weeks.
