Installing LAME mp3 exporter for AUDACITY...

From the Audacity site:

Mac OS 9 or X
-Go to the LAME download page.
-Download the version of LameLib for your operating system.
-When you have finished downloading, use Stuffit Expander to extract the files. (This may happen automatically.)
-Save the file called "LameLib" anywhere on your computer.
-The first time you use the "Export as MP3" command, Audacity will ask you where LameLib is saved.

LAME download page is at http://spaghetticode.org/lame/

Well, I just installed the beta version a couple of weeks ago and had no problems. But the LameLib file I have is different than the one on the site.
And the readme just refers to if you want to rebuild it. But all I did was put the file in <HOME DIRECTORY>/Library/Application Support/Audacity and then start up the program. If you go into preferences you can have it search for the LameLib, or just tell it where you put it. That should be it.
If that doesn't work for you let me know and I can email you the file I used.

just went through the same problem. When asked by audacity to choose that specific file, just go to the drop down, and select any file. Then choose the .so file you have extracted. Confirm that you do want to use that file, then no problem.

iMac Mac OS X (10.4.7)

I have encountered the same problem with Audacity and the LAME mp3 library.

I read the txt file that came with the LAME library and it stated that currently the LAME mp3 Library is only coded for PPC Macs and that if you want it for use on an Intel mac it had instructions on how to unpack the source code and edit it ...... I am not a programmer so I have no idea after this point.

I gave up after searching around for an hour and finding the same LAME mp3 libraries all over the net, none of which worked with my Intel Mac or had the required lib file.

Eventually I downloaded a Freeware program from VersionTracker that can convert most audio file types to most audio file types. I intend to record with Audacity into WAV and then just convert the resulting WAV file to mp3 later.

Thats what I did, but its by no means a real solution to the issue of the missing LAME mp3 library, just a way around it, and I would be interested in hearing about a real solution.

Cheers.

LAME and relevant libs are also available through the FINK project ( http://www.finkproject.org/); also through the DarwinPorts project ( http://www.macports.org/). Both of these projects take care of the nitty-gritty details of downloading, installing, building, and managing library dependencies between projects; you don't need to be a developer to use them. Just follow the instructions carefully. As far as user-friendliness goes, I think that Fink is easier to use (the GUI FinkCommander is pretty straightforward). Darwinports does not come with a GUI, but there is a shareware GUI available ("portauthority").

These projects are nice because they give you access to the huge library of available open source projects while keeping stuff completely isolated from your core system.
