Exporting File

I need to export a mp3 and convert it to below format. Need help doing this

Sorry no we didn’t it is in the incorrect format. James was going to follow up with you yesterday with all that information. It has to be G.711 (CCITT) 8khz , 8bit,Mono, u-Law .wav files in order for our system (NGMP) only supports a specific file type, specific bitrate and compression settings. Your file is 64bit, it needs to be converted to the settings provided, there are several programs that you can use to accomplish this i.e. Audacity.

Your file is 64bit,

If you exported an MP3, it’s probably 64kbps (quality), not 64 bit. I would strongly recommend against exporting an MP3 and then converting it to your target format. The sound will accumulate quality damage at each step of the way and may be much worse sounding than you think it’s supposed to be.

I can’t find that particular combination of specifications.

Install the FFMpeg software from here.


File > Export Audio > Format: Custom FFMpeg Export.


  1. Ensure that your Audacity track is mono. If it’s a stereo track, use “Tracks > Stereo Track to Mono”.
  2. Set the “Project Rate” to 8000 (lower left corner of the main Audacity window.
  3. In the Export dialog screen (http://manual.audacityteam.org/o/man/file_export_dialog.html), select “Other uncompressed files”, then click on the “Options” button.
  4. In the Options, set the “Header” to “WAV (Microsoft)” and the “Encoding” to “U-Law”

Note: It will be much better to convert a high quality WAV file into this format than to convert a low quality MP3 file.
