Hi, Thanks for pointing out these two filters. But both filters require frames as input and actually my problem is not to create the graph but to get these frames. The frames should not be read from begin to end (this is what I am currently doing) because the whole audio file has to be decoded. Instead, I am looking for a way to "sample" the decoded file with an interval x.
