Hi, thank you very much for your answer. The problem I have is that I got an audio stream, say 5 seconds long. I want the user to be able to change the volume and the playbackrate while the sound is being played. I'm able to modify those parameters before i call the play() method, but I need to change them while the stream is being played as well What do you mean by "you can upsample/downsample your streams to get the desired efect"? Thanks again Simone
