Popping noise when combining 2 tracks

[Justin Kupka]

I don't think my original message got posted when i was joining the
list, so i shall throw this out there again.

When combining two wav files using sox wavefile1.wav wavefile2.wav
output.wav, i get a distinct popping noise where the two files join.
They are both the same rate freq channels etc.  Even combining a copy of
the same file to itself still gives me this issue.
I am not sure which version of sox is installed, but its definitely
*not* the latest one that just got released.

Any command line parameters or other tricks i can use to get rid of it?

Thanks
Justin

Please see the splice effect (from SoX 14.1.0 onwards).

I think my version of sox is before 14.1.0
Any tricks around my problem with an earlier version?

Thanks

Some parts of this message have been removed. Learn more about Nabble's security policy.

Basically, you need a short cross-fade at the join.  For versions of SoX before `splice' was added, this can be achieved using a combination of the fade effect, either the pad or the trim effect, and mix (-m) combining.  There's a cross-fade script here
http://sox.sourceforge.net/Docs/Scripts
that may go some or all of the way to achieving this.

HTH,
Rob

What happens if you use the --single-threaded parameter?

This is solved using the splice effect (sox 14.1.0) or you could try the crossfade scripts here:
