change mp3 bitrate for recording
  • Hi,

    I've managed to change the default mp3 bitrate of 128k to 192k by editing /usr/lib/airtime/pypo/bin/scripts/ls_script.liq and changing:

    out_mp3 = output.icecast(%mp3,


    to:

    out_mp3 = output.icecast(%mp3(bitrate=192),


    But this doesn't affect the recording bitrate of live shows. Is there a way to do this?

    thanks

    James

  • Hi, We dont officially support this yet. If you want to change this in the code look in "airtime/python_apps/show-recorder/recorder.py"

    and modify
    command = "ecasound -i alsa -o %s -t:%s" % (filepath, length)

    to
    command = "ecasound -i alsa -o %s,128000 -t:%s" % (filepath, length)


    for 128kbps.

    I have not tested this so no guarantees Smile Goodluck!

    Take the aid of one of the best screen and audio recorder software to do this work for you. From my user experience, it can support a wide range of output formats and devices. At the same time, I can use it to skip any unwanted sections and cut my recording to different parts in the way I like. If you get this one, you can also specify configuration at your own will, including bit rate, channel, codec, sample rate, etc.
  • Hi, if you looking for a special program to manage the audio's bitrate, I think you can take a try with AudFree DRM Audio Converter, which is a professional software to resolve your audio annoying. It supports 9 different bitrate settings according to your demand.

    Hope it's helpful for you.
