aresample should take an expression rather than an integer value.
suppose I want to write a graph that 1) upsample by 4x, 2) apply biquad
filters 3)downsample by 4x
currently I have to write something like "aresample=176400, equalizer ...,
aresample=44100". with different file formats it's very inconvenient.
a script would work in many cases. but not all scenarios can be supported
by scripts. It would be better if this could be supported by expression.
