    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 your exported copy. If you do not have one, download the practice clip again and trim it to thirty seconds — about four minutes of work.

    The clip you will edit

    Download the practice audio file (MP3). It opens with a creaking door for roughly ten seconds, then music. That creak is what you cut first.

    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 cracklyGain pushed too highUndo and use a smaller increase
    Music jumps when the voice stopsLevel changed abruptlyChange it across a few seconds, not instantly
    Rule of thumb

    Gain above about 300% will distort. If it sounds crackly, that is why — undo rather than living with it.

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

    Record a short line of your own and put it into the clip. Keep it to one or two sentences — a title, an introduction, or a line that sets the scene.

    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.
