Why would you want to do pitch scaling and tempo scaling in a single 
filter? Pitch scaling is a combo of asetrate and aresample as far as I 
understand. Tempo scaling is what atempo/librubberband/scaletempo does.

I have no use case in my head where doing both makes too much sense. Do 
you?

Thanks,
