#281 repeat not working in a chain of effects

[OzoneGrif]

Hello,

I have this command :
sox.exe input.wav output.wav repeat - trim 0 6 : repeat - trim 0 6 vol 0.5

It takes a one second file input, repeats it infinitely for 6 seconds (so six times), then halve its volume and is supposed to play it for another 6 seconds.

Repeat works on the first chain, but the second chain only plays it once.

This isn't expected to work. The first repeat - belongs to the first effects chain and will consume the entire input file, leaving nothing for the second chain. You can do something like this instead:

sox '|sox input.wav -p repeat -' output.wav trim 0 6 : trim 0 6 vol 0.5
