Hi, Brian it's me again. I tried to use the Dynamic range compression to deform some audio signal and met some error, could you help me figure it out? Thanks!

This looks like you do not have sox installed.

[YazhouZhang0709]

Is this the sox I need to install? https://github.com/rabitt/pysox I already have it installed.

[bmcfee]

@YazhouZhang0709 that's the python wrapper, but it still needs the command-line sox program installed. Check the install instructions on pysox.

[bmcfee]

@YazhouZhang0709 can you confirm that sox was the issue so we can close this out? (Or think harder about it, if sox was not the issue.)

[YazhouZhang0709]

Ok. Thanks

[bmcfee]

Thanks!
