We have a customer that does not care for the default MoH.

We have downloaded some royalty free music but it sounds ‘fuzzy’ when we
test it with the system.

We down sample it to 16bit, 8KHz, Mono. We have tried with Audacity,
CoolEdit Pro, & VLC.

Does someone have a file they can send me that we can test with, or has any
tips?

Much appreciated,
Matt

  • Steve,

    Did you use this syntax to convert:
    sox foo-in.wav -r 8000 -c 1 -s -w foo-out.wav resample -ql

    Close, I don’t do the “resample” effect. Way back when I wrote my
    “transcribe” script it didn’t seem to add any goodness to my prompts.

    Once I have the file in the correct format, I use “normalize”
    (http://normalize.nongnu.org/) to adjust the volume.

    Lately, I’ve been receiving more prompts with visible (as seem in
    Audacity) DC offset so I’m looking for command line tools to correct
    that as well as high pass and low pass filters. I think the newer
    (than distributed with CentOS 5.x) version of sox will handle
    everything I need.

    Anybody care to volunteer their transcoding script?

  • On my own version of sox (14.3.0), says -w option is not allowed
