sox FAIL util: Unable to load MAD decoder library (libmad) function “mad_stream_buffer”

Question

I compiled libmad for sox. When I try to read an mp3 I get this message:

sox FAIL util: Unable to load MAD decoder library (libmad) function "mad_stream_buffer".

Did I compile the project incorrectly?

Answer 1

Steps to using SOX to create MP3s:

1. Download latest version of SOX and install.
2. Download libmad-0.dll and libmp3lame-0.dll. The currently only known trustworthy source is ossbuild but this requires you to download a 1.5 GB archive. The selected two files are available here and here.
3. Add libmad-0.dll and libmp3lame-0.dll to the folder where SOX was installed to.

4. Use the command line to convert a file to .mp3:

   sox input.wav -c 2 -C 128 output.mp3
   

Note: -c 2 makes it stereo, -C 128 specifies output as 128 kbps MP3
