How to Record Audio-Only Course Lessons Using GarageBand

Open GarageBand on your Mac and select "Empty Project." When it asks what type of track, choose "Audio" with the microphone icon. This creates a single voice track. Make sure your input is set to your external microphone (USB mic or audio interface) rather than the built-in Mac mic. You can check this under GarageBand > Settings > Audio/MIDI.

Set your project tempo and time signature if you're syncing to music, but for spoken-word lessons you can ignore these. The only setting that matters is the input source and the sample rate — 44.1 kHz is standard and fine for course audio.

Position yourself about 6-8 inches from your microphone, hit the red Record button, and teach your lesson. Don't worry about being perfect. You'll trim mistakes and pauses in the editing step. The key is to record in a quiet environment — close the door, turn off fans, and put your phone on silent. GarageBand's noise reduction helps, but it can't rescue audio recorded next to a running dishwasher.

A practical tip: record your entire lesson in one pass, pausing for a few seconds when you make a mistake. Those long pauses are easy to spot visually in the waveform and simple to cut out. This is faster than stopping and restarting for every stumble.

After recording, trim the dead air at the beginning and end by dragging the edges of your audio region. Cut out any long pauses or mistakes by selecting the section and pressing Delete. GarageBand's "Split at Playhead" function (Command+T) lets you isolate and remove specific segments cleanly.

Apply two effects to your voice track to bring it up to a polished standard. Click on the track, open the Smart Controls panel (press B), and add:

• Noise Gate — reduces low-level background noise between phrases. Set the threshold just above your room's ambient noise level.
• Compressor — evens out your volume so quiet words and loud words land closer to the same level. Use a gentle ratio (2:1 or 3:1) for natural-sounding speech.

These two effects handle 90% of what makes amateur audio sound amateur. You don't need to touch EQ or reverb for straightforward teaching audio.

Create a second track (Track > New Track > Audio). Open the Apple Loops browser (press O) and search for ambient sounds. Filter by "Cinematic" or "Ambient" for meditation courses, or "Acoustic" for coaching sessions. Drag a loop onto Track 2 and extend it to cover the length of your lesson.

The most important step here: lower the music volume dramatically. Your voice should be the clear focus. Pull the music track's volume slider down until the music is barely noticeable — think 15-20% of your voice level. If a listener has to concentrate to hear the music underneath your voice, you've got it right. Music that competes with the instructor's voice is the number one audio mistake in course production.

Listen through the entire lesson with headphones. Check that your voice is clear throughout, the music doesn't spike or dip in distracting ways, and there are no pops or clicks at edit points. Adjust levels if needed.

When you're satisfied, go to Share > Export Song to Disk. Choose MP3 for smaller file sizes (good for lessons under 30 minutes) or WAV for maximum quality (better for longer meditation recordings where audio fidelity matters). MP3 at 192 kbps is the sweet spot for spoken word — small files, no audible quality loss.

After setting up your first lesson with the right effects, levels, and music bed, save the project as a template. For each new lesson, duplicate the template file and record over the voice track. This keeps your audio quality consistent across every lesson in your course — same EQ, same compression, same ambient music level. Students notice inconsistency even when they can't name what changed.

GarageBand lets you draw volume curves on any track (press A to show automation). Use this to fade your music bed in at the start and out at the end of each lesson. A 5-second fade-in at the beginning and a 10-second fade-out at the end creates a professional feel that signals "this lesson is starting" and "this lesson is ending" without you needing to say it. For meditation courses especially, these transitions matter — they set the tone before you even speak.

If you're on Windows or Linux, you'll need Audacity or another cross-platform tool. GarageBand also lacks some advanced audio features that professionals rely on — spectral editing, advanced noise reduction profiles, and batch processing for multiple files. For a 10-lesson meditation course, these gaps won't matter. For a 100-episode podcast production workflow, you might outgrow it.

GarageBand doesn't do text-based editing. If you'd prefer to edit your audio by reading and deleting text from a transcript rather than scrubbing through waveforms, Descript handles that workflow. For most audio-only course creators, though, GarageBand's visual waveform editing is straightforward enough.
