Audio Processing APIs?

Question

We have an app that uses DirectShow to allow us to analyse music files (mp3, m4a, etc.). We're basically using DirectShow to decode the audio, along with a SampleGrabber-style filter to inspect each sample.

We also do audio manipulation, and need to re-encode the music back to mp3 format.

Is there an equivalent of DirectShow that can be used from metro-style apps? If not, what would be the suggested route for re-implementing?

Answer 1

You should be using Media Foundation which is the successor to DirectShow.

The Media Foundation APIs are accessible from Metro apps, see the following link for more details.

Thanks Anon.  In addition to the link Anon posted, you may want to look at the Media Plugins Sample:
