This Instructable is for a Mac. If you're on a PC, click here.Hi there! This Instructable shows you how to "download" any song you want to your computer, absolutely free.From this Instructable, you'll be able to save to your hard drive your favorite music, expanding your music library.Note: this system requires no outside reworking of your computer: no cables, no amps, nothing.
Step 1: How it WorksThis system is called "internal recording." It's legal, free, and it's impossible to get a virus from it. (Then again, you are on a Mac, so this shouldn't be an issue.)This system is the equivalent of plugging in a microphone and recording the music as it comes out of your speakers. However, this way, no quality is lost, because the audio being recorded has never actually left the sound card.Legality: internal recording is legal under the DMCA, because it's essentially the equivalent of recording radio. (Note: I might be wrong, so don't sue me.)
Step 2: What You'll NeedYou're going to require a few programs in order to get this system running.Here's what you'll need:1. Audacity: if you don't have this, get it. It's a wonderful (free) audio-editing app. This will also serve as the recording station for your music.2. SoundFlower: this is the essential piece. If you can't get this, just go back to your torrents. This is the program that make the recording possible. And it's free, too.3. LAME mp3 encoder: save this in a place where you'll remember it, because Audacity's gonna ask for it.That's it. Now you've got to configure.
Step 3: Configure
This is to set up the recording system.
1. Go ahead and install and run both SoundFlower and Audacity.
2. In Audacity, under Preferences, click "Recording" and set the Input to "SoundFlower (2 channels)."
3. Launch System Preferences-->Sound. Under "Sound Effects," make sure that the box labeled "Play user interface sound effects" is unchecked. Under "Output" and "Input," set "Soundflower (2 channels)" as the device.
You're now ready to record.
Step 4: Record!
You now must find the audio which you want to record. If you're recording music, I'd recommend a site like last.fm or Grooveshark, both of which are sites that let you listen to entire songs for free.Once you've located your music of choice, do the following:1. In Audacity, click "Record."2. Start playing the music. If you look in the Audacity window, you should see that something's being recorded.3. When the music finishes, in Audacity click "Stop."4. Select the parts of the audio that make up the sons, and click File-->"Export Selection to MP3..."5. Fill in the asked-for data and finish the export.6. Congrats! You've now internally recorded your first music! Go send it to iTunes and celebrate!
