#766 closed defect

Bad audio quality (possibly in resampling) in Linux (thanks Thomas Kluge for the report) — at Version 1

Reported by: bennylp Owned by: nanang
Priority: normal Milestone: release-1.6
Component: pjmedia Version: trunk
Keywords: Cc:
Backport to 1.x milestone: Backported:

Description (last modified by bennylp)

task: resample from 44.1KHz to 8KHz

cmdline: ./pjsua --null-audio --clock-rate 8000 --play-file nanotech44.wav --rec-file output8.wav

The results:

  • Vista, VS6: ok
  • Vista, Mingw/gcc-3.4.5: ok
  • Linux1, gcc-4.3.2: bad
  • Linux2, gcc-4.1.1: bad

I'm somehow still 100% convinced that this is Linux thing, as I don't suppose there's any platform specific processing there. It could also be something specific to gcc 4. If someone has gcc 3, on Linux, to test this with, that will be great.

The corresponding ticket for the 1.0 branch is #767
