Ifyou put lame_enc.dll in the same folder you have Audacity installed in, MP3 export should just work, as long as there are no conflicting settings anywhere telling Audacity that lame_enc.dll is somewhere else.
Audacity is a free, open source software for recording and editing sound. It is available for MacOS, Windows, and Linux. This FAQ should hopefully get you started. If you have other questions feel free to post in the LibriVox Forums
The exception is for LINUX users who must still install it. You will also need the LAME MP3 encoder. It is a free, open source plug-in used to create (encode) MP3 files from your recordings. You can download it from here:
If you recorded on tape and want to transfer to your computer you can also use Audacity. Use the same settings as above except you choose Stereo for Channels and mark the box labelled Software Playthrough... example
Click the round red button to start recording. If you want to take a break and hit Stop (Yellow square), the next time you hit Record again it will start recording at the end of the track. If you want to record on multiple tracks, hold down the Shift key while clicking the Record button.
When you save in Audacity it creates an AUP (AUdacity Project) file. These aren't very useful for sharing, but it is a good intermediate format to use while you are editing. An AUP maintains all the tracks that you have from starting and stopping the recording. If you would like to collapse all these tracks together you can choose File > Export to WAV. This will create a new file which has only one track. If you open this file in Audacity it would be easier to edit. We encourage you to save often!
When you make mistakes it's usually easier to just re-record the section you want immediately. You can tap the microphone base a few times before re-recording so that it is easier to see where you need to make the edits. Do not tap the microphone itself as this can damage it. Other readers also say "pickup" or click their tongue. Whatever method you use just makes it easier to see edit points.
Although the above method is probably the easiest when first starting out, Audacity has the option to use the punch and roll method. This means that after you make a mistake you can stop recording and immediately re-record the flubbed line, without the need to edit out the mistake later. Devorah Allen (mightyfelix) demonstrates how to use this method here
Audacity allows you to choose Stereo or Mono when you start your recording. Since most of us don't use Stereo microphones, choose Mono. When you export the file it will end up playing back in Stereo. Recording in Mono just instructs Audacity to apply the same content to both left and right.
First make absolutely sure that you have set your recording preferences as Mono in Edit Preferences Devices Recording Channels, and that you have selected Joint Stereo as the Channel mode in the Options when you export the MP3.
If both of these are correct, and you are still told that your MP3 is Stereo, there is only one explanation that we have found: in Audacity, you will see a slider to the left of your mono track which looks like this: . If this is not correctly centred, then (for some inexplicable reason) Audacity will export your MP3 as a Stereo file.
I used the homebrew LAME using brew install lame which placed the executable at /usr/local/bin/lame which then worked fine, I give instructions to macOS users on how to do this should they require MP3 encoding on macOS using my software.
As you know, the EVE University Class Library is an invaluable knowledge base for new capsuleers. This guide will illustrate, step-by-step, how to record, encode, edit and upload your class recordings. We encourage unistas to record classes they attend.
Recording a Class is simple enough; Once you join the class sub-channel under Class.E-UNI on Mumble, click the red button on your menu, select Mode: downmix, select your output format (for the purposes of this guide, it is assumed you're using .wav format.) When you're all set, hit Start. Please be informed that you can not join the channel Class.E-UNI directly, but you must join the sub-channel with the name of the class.
After you record the lecture, you might need to edit it: the class might have started late and you want to remove the first 2 mins or maybe you forgot to stop the recording and you recorded 30mins of silence. Whatever the reason, if you need to edit the file, you can use a software such as Audacity, its a free, multi-platform and easy to use program and in the following sections we'll demonstrate its use. You can always use other software if you prefer to do so.
Please download & install Audacity and install the lame encoder for audacity, we'll need it to export our class audio files into mp3 in later steps. You can download audacity from this link and lame encoder for audacity from this link. Please check this page for instructions on properly installing the encoder. We will not provide the details of installing the software or the encoder as the steps or methods may vary between different platforms.
You can use EVE-Files to upload your EVE related files, or any other publicly accessible file storage service, e.g. Dropbox, Google Drive. Just remember that the file may need to be kept available for a very long time, so don't use a service that automatically deletes files after a short period of inactivity. When you're done uploading the file, please see this forum thread and scroll down to 4. Posting your files section for further instructions.
LAME for Audacity is a software application that provides users with the ability to export MP3 files directly from the popular audio editing software, Audacity. This tool is a free and open-source MP3 encoder that allows users to save their audio projects in the widely-used MP3 format.
To use LAME for Audacity, simply download and install the application on your computer. Once installed, you can access the MP3 export functionality directly within Audacity. When you are ready to export your audio project as an MP3 file, simply select the option to export as MP3 and adjust any encoding settings as needed. LAME for Audacity will then encode your file into the MP3 format with the specified settings.

Audacity is the program I recommend for recording and editing sound. It's a free program and you can always find the latest version at
www.audacityteam.org. In addition to installing Audacity you'll also want to install these import/export plug-ins: Lame, FFmpeg, and LADSPA. Links to all of these can be found on the Audacity Team website, or you can download the current versions (as of January, 2019) here:
What follows was written 10 years ago to show how to use Audacity to create voice-overs for a slide show, but the first part on Audacity is worth reading, nothing much has changed, you can stop when you get to the part about ProShow unless you're interested.
For making Slide Shows I recommend ProShow Gold. In ProShow options, I specify Audacity as my audio editor. You can get Audacity free from
www.audacityteam.org. I recommend going ahead and using Audacity version 1.3 instead of version 1.2. Download and install. While you're there you also want to get the Lame encoder (under optional downloads) which you can unzip into the audacity folder. This encoder is needed to export MP3 files from Audacity.
The best technique for creating voice-overs depends on the show you're creating. Some shows are best created by creating the script (the voice-overs) first and then add slides to the time line and attach voice-overs, editing the timing of the slides to fit. That technique seems to work best when you're telling a story and adding images to fit the story; in this case it's easiest to create the voice-overs in Audacity. Other times the images are the story and you just occasionally want to add voice-overs to talk about some of the images; in this case it's easiest to create the voice overs from ProShow.
(Occasionally, if you speak one word much louder than the rest, this may not amplify it enough. In this case do it again, but this time check the "Allow Clipping" box and specify a new peak amplitude of 5 or 10; 10 will double the current maximum level.)
On the "Save as type" pull-down, choose "Ogg Vorbis" (or MP3 if you've installed the Lame encoder). Be sure you save the sound clips in the folder with the images for your show. I recommend you name the files with leading numbers (like 0010, 0020, etc.) and some kind of name to remind you what the clip is about ... the leading numbers will keep them roughly the order you plan to use them in your show. You'll also get a menu asking you to fill in genre or metadata information, the one from Audacity 1.3 looks like this:
You see it's already assigned a name (highlighted) based on the name of the show and the slide number (along the time-line). The very first time you do this click on the "Browse" button to make sure it's putting the sound clip in the right folder (and not the folder with the previous show you created). When you're ready, click "Record". You get this menu:
You'll notice the "Edit" button is no longer grayed-out. Click on it to open it in Audacity, and repeat the steps shown above (delete lead-in and lead-out, amplify, export). When you export you'll get:
Use the pull-down the first time to double check the folder it's putting it in (change if it's wrong). You'll get a warning that you're overwriting the file ... that's good if you don't get the warning you've lost it in some other folder. Close Audacity, ignore the warning about saving the project; you've just exported the sound wave, you don't need to save the project. (If you don't close Audacity you'll end up with dozens of copies open.)
