Convolution filtering

[JackFil]

Yes Simon, thank you, that's it! Since the beginning I thought the convolution file had to be generated in mono according to what I saw a couple of pages before but I may have misunderstood.

In stereo, no fast speed issue anymore :-).

Nevertheless I still have a gap (using RuneAudio as renderer) between the songs even when I follow the instructions: Same value "x" for apad & atrim functions => x = 0.5 * (the number of taps in the convolution file).
Would anybody have a RPi renderer to recommend? Maybe shall I install it on the same RPi as Minimserver&Streamer.

Thanks in advance.
