DirectShow and RenderFile

Hi there!

Currently I am developing an application to play any kind of audio-data and fade between two sources. This project will hopefully end in an virtual DJ mixer that can be combined with my DMX512-lighting software to help DJs doing a great show .-)

The problem I am facing is some kind of buffer underrun that happens, when I load a new mp3-File while another one is being played. I get a short ugly noise that really disturbs the experience.

Can anyone help me out and tell me how I can load a new MP3 while another one is being played _without_ some noise? I use RenderFile() to load the files.

Bye,
Marc
