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?

Solution 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

Solution 2

You can download SoX binaries together with libmad.dll and libmp3lame.dll from http://www.videohelp.com/software/SoX

Useful article because the "finished" version (sox compiled with lame and libmad) is included.

Here is the updated URL ossbuild.googlecode.com/svn/trunk/Shared/Build/Windows/Win32‌​/…

I spent an hour fussing with trying to install LAME manually before I happened across this. Thank you and OSSBuild!

@bulltorious, I can not download libmad-0.dll and lbmp3lame-0.dll. If I press Download button in Box, I get error in Firebug: "NetworkError: 403 Forbidden - https://app.box.com/index.php?rm=box_download_shared_file&sh‌​ared_name=tzn5ohyh90‌​viedu3u90w2l2pmp2bl4‌​1t&file_id=f_6925695‌​2453". Thanks.

As of August 2017 .DLLs are still there in 1.5 GB archive. Thanks.

the link for just the two files is dead.

Download mirror: libmad-0.dll and libmp3lame-0.dll.

Working like a charm

Confirmed working on windows 10 pro, 64bit (the two "single file" links still work for me, I used the 7 zip version)
