Audacity Lame Mp3 Encoder Download Mac

The LAME encoder is a separate program that needs to be downloaded so that you can create MP3 files. There is a technical reason why LAME is not included with Audacity. You don’t need to understand that. Just realize it means that you must get this software separately. So there is a required extra step to obtain it. LAME is only distributed in source code form. For binaries and GUI based programs which can use LAME (or include fully licensed versions of LAME), check the LAME related links. All software from the LAME project can be found in the project's file area. Current Versions. The current release version of LAME. Install Lame MP3 Encoder. Download Lamev3.99.3forWindows.exe. Run the exe file to install LAME for Audacity on your computer.

Audacity is a great program for missionaries to use for audio editing and sound production.

There are many reasons why a missionary or pastor may want to use audio editing software and Audacity is a great free option to fill this need.

Suppose you have a great sound recording of a remote village service. But the recording is two hours long and you need to cut out extra content before emailing it to your supporters. Or maybe you want to create a podcast of your ministry experiences or to distribute your church services.

Audacity is a great tool for any of these projects and many more. However, setting up Audacity to make MP3 files that are small enough to distribute easily can be confusing. Installing Audacity—a piece of sound editing software that works on multiple computer platforms—is just like installing any other software. The problem comes in getting the MP3 encoder set up properly. This encoder is called LAME.

Installing Audacity

You can grab Audacity from their website. It is available for Windows, Mac and Linux. To me, this is one of the things that makes Audacity so powerful. I use all three platforms. I always look for tools that I can learn on one system and be able to use on any other one. We call this a cross-platform application.

If you have tried Audacity in the past you may remember that there were two different versions; a development (beta) version and a stable version. As strange as it sounds, the beta version was always more stable in my experience than the stable branch. Now there is just one version and it has been very solid for me. Regardless of what your experience with Audacity may have been years ago, it is well worth you giving it another try.

Installing Audacity is just like installing any other software for your platform. If you are not the one who normally installs software on your machine, then you can ask your administrator to do it for you.

Linux users may want to check your distribution’s program repository for an easy-to-install version for your distro. You could build Audacity from source if you choose. I never choose to do this if I can avoid it.

To record, press the red record button. Or press the letter R on your keyboard.

Before you go any further with installing the extra features mentioned below, I suggest you turn on Audacity and make sure everything is working. Try making a recording by hitting the red recording button. If you can’t figure out which one it is, then hover over the different buttons on the top left of the screen and you will get a pop-up hint. Or, you can press the letter R on your keyboard and Audacity will start recording. If your computer has a microphone built in, then you will probably see the mic input indicator move and sound waves will show up in the bottom portion of your screen. If you have a mic on your computer and it does not pick up sound, then try to select a different mic input with the drop-down menu and see if that takes care of it.

If you don’t have a mic plugged in or the drop-down menu does not help you start recording then you will have to look into other possibilities for the problem later. But I don’t suspect that will be a problem. Nor do you need to worry about that right now. We are only trying to confirm that the program is running without any problems so that we know if potential upcoming problems are related to the following additions to Audacity or if the problem is Audacity itself.

If Audacity is running right now, then you can proceed to the add on features.

LAME Encoder

The LAME encoder is a separate program that needs to be downloaded so that you can create MP3 files. There is a technical reason why LAME is not included with Audacity. You don’t need to understand that. Just realize it means that you must get this software separately. So there is a required extra step to obtain it.

Download the appropriate LAME encoder to your computer.

On Windows you can download an installable .exe for LAME. On the website it is called Lame_[some-version-number]_for_Windows.exe. You install it like a normal Windows program and you are done. Be sure to install it in the default location so that Audacity can find it on its own. Otherwise you will have to manually tell Audacity where to find the encoder when you first try to export an MP3.

Audacity Lame Mp3 Encoder Download Mac Installer

For Mac you need to download the LAME .dmg file and then double click it once it is downloaded to your system. After the .dmg (disk image) is open you will find the LAME package file (a .pkg file) that you can double click and install with a standard Mac installer. Install this into the default location and Audacity should find it automatically. Otherwise you will have to tell Audacity where to look for the encoder when trying to export an MP3 for the first time.

In my case, and I am wondering if this is due to recent Mac OS X updates, the LAME install did not go as easily as it should have. The installer puts the file libmp3lame.dylib into a folder called /usr/local/lib/audacity/. This is a hidden folder. If you have to manually navigate to the folder to tell Audacity where the LAME encoder is (which you should not have to do), then you won’t be able to do it. I ended up downloading the .zip file at the LAME for Audacity download page and extracting the file I needed–which is libmp3lame.dylib. Then I save that to my downloads folder on my Mac and pointed Audacity to that file when it asked me where the LAME encoder was.

It will depend on your distribution of Linux as to where to download the LAME package. Most likely your distro will have LAME as an installable package from your package manager. You may have to turn on (or unblock) restricted packages. However, some Linux distros take care of LAME installation at the same time they install Audacity.

FFmpeg Installation

The FFmpeg program is a set of codecs that allow you to import and export a large variety of audio files that Audacity does not import/export natively. For the same reason Audacity can’t package the LAME encoder with the installation, it also cannot install the FFmpeg program. Therefore it has to be manually installed.

Fortunately this installation is done just like the LAME installation for the various platforms and you can get FFmpeg at the same website as LAME.

FFmpeg is not absolutely necessary, but is very helpful. This will allow you to import AAC files (the iTunes native format), WMA, M4A and several other formats. These must be DRM free files as FFmpeg does not crack DRM.

Recording Audio

The following instructions are taken specifically from the Windows version of Audacity. If you are using a Mac or Linux system the steps are almost identical. Where they are not exactly the same, it will be so close to the same steps you probably won’t notice the difference. That is the beauty of cross-platform tools like Audacity.

Let’s go back to actually trying to record something with Audacity. Open up the program and hit the record button (or the letter R). If something records, then have fun playing with it for a few seconds. Record at least a minute’s worth of sound so that you can see what a difference the two main file types will make. You can stop recording by pressing the space bar or clicking the yellow stop button.

Plug-Ins – Download additional effects and filters.

Save your recording by choosing File | Save Project. This will create an Audacity project which consists of a filename.aup file and a folder with the same name with _data added to the end of the folder name. I recommend that you always save the “project” even if what you want is a WAV or MP3 sound file. This will allow you to work with the original file in the highest quality without multiple conversion steps which can degrade the sound file.

After saving the project you want to export a WAV file. Mainly this is for testing and illustration purposes, not because you always have to do this. Choose Export from the File menu. Then make sure that the drop down box labled “Save as type:” has the “WAV (Microsoft) signed 16 bit PCM” option selected. This works on Mac and Linux too. This is a file type and not tied to any particular platform. There are no options to select, even though there is a button which says Options. Name your file and save it where you can find it again. In the Edit Metadata box that pops up, leave all of that blank for now.

Now go to File | Export again, but this time choose MP3 as your file type. Save it in the same location and don’t worry about the Options right now. Here are some recommended settings for the MP3 export. Again, don’t enter anything in the Edit Metadata box right now.

The Power of MP3

An MP3 file is a compressed audio file. This means that some of the audio information is extracted (and destroyed) in an effort to make the sound file smaller. If done properly, then you can reduce the size of a file significantly without any discernable loss of quality. Or, you may accept and hear some quality degredation in an effort to get an even smaller file for your purposes. A WAV file is a sound file that has all of its original audio information, but is considerably larger than an MP3.

Go to your Finder in Mac, your Windows Explorer (My Computer) on Windows, or your file browser of choice on Linux. Find your two files: WAV and MP3. The purpose of this is to see the space-saving ability of MP3 compared to full quality WAV files.

In your file browser (Finder/Windows Explorer/Dolphin, etc.) look at the sizes of the various files. You may need to right-click on them and choose Info or Properties to see the file size.

For a 40 second sound file that I just recorded the MP3 file is 949 KB. And the WAV file is 6,965 KB. This means that the MP3 is 1/7 the size of the WAV. You can start to see the drastically different sizes of MP3 files compared to WAV files.

Looking at the properties of a file I edited a few days ago that is 4 minutes 30 seconds long, you can see that not all files compress the same. The WAV is 23.5 MB in size and the MP3 is 6.4 MB. (I changed from KB to MB because the larger file sizes are easier to talk about in this unit). So the MP3 is now only 1/4 the size of the WAV. While the file sizes may not always be a certain proportion to one another, the MP3 will always be significantly smaller.

EEK! Exporting the MP3 Didn’t Work!

When you tried to export the MP3 did you get a pop-up box asking you to point Audacity to the LAME encoder? That means that one of the steps above for installing LAME did not work. Don’t fret. You simply need to try and find the LAME encoder on your computer and tell Audacity where it is.

In your file browser do a search on the whole hard drive for “lame” (without the quotes) and find the lame_enc.dll (for Windows) and its location. For Mac you need to find libmp3lame.dylib. On Linux do a search for Point Audacity to the appropriate file once you find in its proper location. If you don’t find the file you are looking for, then go back and redownload and reinstall the LAME encoder from above.

Importing Audio

Instead of recording directly into Audacity, you can import audio that you have recorded on a portable recorder. This is what I do all the time and rarely ever record directly into Audacity. Practically it is easier to carry a portable recorder with me to record in the field than to carry a whole computer. But, because of the nature of recording into a hardware recorder versus a computer, a hardware recorder is always going to be more stable. Recording directly into Audacity (or any software based recorder) risks the possibility that your sound won’t record, your computer will freeze or the software will shut down. Because they only do one thing, hardware recorders are much less susceptible to those problems.

You can open Audacity and then click File | Import | Audio. Alternately you can open Audacity and then drag the file you want to import from a file browser window. From here you can edit your sound file and export it as an MP3.

Where to From Here?

There is so much more to learn about audio editing than I can cover here. There are some wonderful YouTube videos available to teach you how to use Audacity. Most of what I know in all of this has come from asking Google questions and applying what I have learned.


Some of the first things you should work on are:

That should get you on your way to grabbing good recordings and making them useable for your friends and supporters. And don’t forget, all this power is free.

Audacity is free, open source software that makes it simple to record and edit audio on your computer. Installing Audacity on a MAC isn’t difficult, there’s an extra step that’s often overlooked if you want to save your recordings as MP3s, rather than much relatively large WAV files.

To download Audacity, go to the Audacity downloads page ( and choose the appropriate version.

In this walkthrough, we’ll be looking at downloading and installing Audacity on your MAC.

There are a few versions available for you to download, but we recommend you download the first .dmg file.

Lame ACM MP3 Codec By The LAME Project - Should I Remove It?

Depending on your browser and set-up, the file may automatically be saved to your downloads folder. If not, click SAVE FILE and choose a location on your computer where you’ll be able to locate the installer if necessary

Double-click the downloaded DMG to mount it.

Do not double-click the “Audacity” folder in the DMG window. Drag the entire “Audacity” folder icon to the /Applications folder icon on the right (or to any other location of your choosing).

Eject the DMG at bottom left of Finder, then launch from the “Audacity” folder in /Applications or from your chosen location.

Known Issue: Security settings on OS X 10.7 or later may block Audacity being launched. Most users on OS X 10.9.5 and later will experience this, due to changes made by Apple.

To permanently enable Audacity launch, right-click or control-click on the Audacity application in Finder, choose “Open”, then in the dialog box that appears, choose “Open”.

If exporting your recordings as rather large WAV files is sufficient, then you’re all set. We recommend installing the LAME MP3 library, which will allow you to save your recordings as much smaller MP3 files.

Audacity Lame Mp3 Encoder Download Mac

To download the LAME Library, launch Audacity. Then click EDIT, choose Preferences, select LIBRARIES, then under the MP3 Export Library section, click DOWNLOAD in the LAME MP3 Library line.

Once the Lame Library mounts, double click the .pkg file to run the installer, then click Continue. Select your hard drive to install, click Continue, then Install. Enter in your computers password if prompted, then click ok. Once it’s finished, click close to exit the installer.

Now you’re ready to export your Audacity recordings to MP3 as well as WAV.
