Bug 58461 – sox-12.17.4-r1 segfaults when changing sample rate

• Status: VERIFIED NEEDINFO
• Product: Gentoo Linux

[Description Thomas Petersen 2004-07-26 12:56:20 UTC]

When using sox to change sample rate of a file without specifying any rate changing filters on the commandline it segfaults. According to the manpage it automatically select the resample filter. When specifying that it should use the "rate" filter instead it works fine. It sounds like a problem in the resample filter.
The filter seems to work fine on x86.

The file i'm working on is a short wav file in mono, 8 bit, 22050 Hz.
Trying with mp3, stereo, 16 bit, 44100 Hz also segfaults so i don't think the format matters.

Reproducible: Always
Steps to Reproduce:
1. Execute: sox input.wav -r 8000 output.wav
Actual Results:  
Segmentation fault
and a zero byte output file.

Expected Results:  
output.wav sounding like input.wav but in different sample rate.

Can confirm this. A quick look at the backtrace confused me... and the code of this does that even more...

They play around with pointer/integer conversations. I will try to look into it at
the weekend...

Ancient bug, no reply in over six months. Closing, marking NEEDINFO - please feel free to reopen if this still causes problems under Gentoo/AMD64 2005.0 and be sure to supply up to date and pertinent information at that time.

I have just tested sox-12.17.5-r1 (latest stable). Both rate and resample seem to work without segfaulting.

Excellent, marking bug as closed.
