oversampling and digital filters
I currently use a non-oversampling TDA1541a DAC. I am concerned with some of the potential problems from high frequency harmonics that might upset my amplifier and or tweeters. Therefore I would like to operate the DAC with oversampling and digital filters. I understand that the filtration and oversampling can be done within the raspberry pi software. Could someone please provide some guidance on how I might do this.

Many thanks,
I think you have to use something like bruitfir or ecasound but I don't have any experience installing or configure these packages. There are some good threads on this at diyAudio Forum.
