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?

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

  • I spent an hour fussing with trying to install LAME manually before I happened across this. Thank you and OSSBuild! – Mr Griever Oct 02 '15 at 17:38
  • @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&shared_name=tzn5ohyh90viedu3u90w2l2pmp2bl41t&file_id=f_69256952453"`. Thanks. – Саша Черных Nov 09 '16 at 15:36

    As of August 2017 .DLLs are still there in 1.5 GB archive. Thanks. – Maris B. Aug 11 '17 at 12:53
  • the link for just the two files is dead. – Matt Jan 24 '18 at 22:23

    Download mirror: [libmad-0.dll](https://archive.org/details/libmad-0.dll) and [libmp3lame-0.dll](https://archive.org/details/libmp3lame-0.dll). – Vlastimil Ovčáčík Aug 18 '18 at 18:53

  • Confirmed working on windows 10 pro, 64bit (the two "single file" links still work for me, I used the 7 zip version) – 576i Dec 19 '19 at 10:03

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

for compiling from source:

since the the tutorial http://www.codeproject.com/KB/aspnet/Compiling_SOX_with_Lame.aspx is rather dated (and did not work for me with more recent VisualStudio versions):
the SOX project contains ready-to-use Visual Studio projects for compiling SOX and its dependencies/libraries on Windows (e.g. using a Visual Studio Community Edition).

The SOX source code repository at SourceForge contains a directory msvc10 (and also msvc9) for compiling SOX and its dependencies with VisualStudio. Detailed instructions for that are in the Readme.txt.

So, for example, for only compiling libmad.dll:

  • clone SOX repository, e.g. to directory sox-code/
git clone https://git.code.sf.net/p/sox/code sox-code

sox-code/
libmad/
  • open the VisualStudio project file (*.sln) in directory sox-code/msvc10 (if needed, change build configuration form Debug to Release)
  • in the Solution Explorer window open context-menu for sub-project LibMad and select Build (or in older VS versions Project Only → Build Only LibMad)
  • afterwards the compiled DLL is in sox-code/msvc10/Release (or Debug depending on the selected configuration)

tested with VisualStudio 2010 and Visual Studio 2017 CE
