Resampling inconsistency

Resampling inconsistency

Hi,

Is there a way to make sox produce consistent output? If I run

$ sox infile.wav -r8k outfile.wav

twice, the two outfiles are very subtly different.  0 vs -1 or 356 vs 357, etc... just a lot of off-by-one differences.  I need to ensure they're identical, the subtle differences between runs are throwing off some of my test cases.

Can this be done with sox?  Ideally I want to only store the original and create the downsampled versions when needed.

I'm running v14.4.1.

Thanks!?

The option you want to include in the command line is "-R", which is described in the "Options" section of the man page.
