Editing Audio with Audiomass, Part 2: Your Voice and the Mix

Students record their own voice on a second channel under last lesson's clip, balance the two by turning the music down, and export a checked MP3. This lesson counts towards outcome 3.8: students use these editing skills to build their digital montage in the montage lessons that follow.

    1 - Start ~3 mins

    Illustration for StartYour thirty-second clip has music and nothing else. Today you add the thing that turns a clip into a piece of media: a voice.

    You will need your file from last lesson

    AudioMass keeps nothing after the tab closes, so load the MP3 you exported last lesson. If you do not have it, the practice clip below takes about four minutes to trim again.

    Lost your clip?

    Download the practice audio file (MP3) again, cut the creaking door off the front (about the first 8 seconds), trim it to thirty seconds and fade both ends, as you did last lesson. Last lesson's steps show each move if you need them.

    2 - Why Balance Matters More Than Volume ~5 mins

    When a voice and music are heard at the same time, the problem is almost never that the voice is too quiet. It is that the music is too loud underneath it.

    What you hearWhat is actually wrongThe fix
    Cannot make out the wordsMusic competing with the voiceBring the music down under the voice, not the voice up
    Voice sounds harsh or cracklyRecorded too close to the microphone, or shoutingRecord it again a hand's width back from the microphone, in a normal speaking voice
    The music drowns your first wordThe voice starts on a loud part of the musicDrag your voice a second to the right, or turn the music down further
    Rule of thumb

    Turn the music down, not the voice up. In AudioMass the music and your voice each sit on their own channel, a separate row with its own volume, and each channel's volume only goes up to 100%, so the way to make room for a voice is to bring the music down.

    3 - Hands-on: Record Your Voice ~13 mins

    Record a short line of your own and lay it over the music. Keep it to one or two sentences: a title, an introduction, or a line that sets the scene.

    Open AudioMass at audiomass.co. It ends in .co: audiomass.com is a different site, full of adverts.

    Before you record

    Plan the words first and say them once out loud. Recording while deciding what to say is what produces thirty seconds of “um”.

    4 - Hands-on: Balance the Levels ~12 mins

    Now make the two work together: the voice clear, the music present but underneath it.

    5 - Hands-on: Export and Check It ~5 mins

    Export it, then listen to the exported file rather than the editor.
