Listen to the edited version seen above Step 4: Shampoo, Rinse & Repeat In my example, this round of adjustments cleared an additional 1.4 dB of space for me to increase! Hit OK and watch as your entire waveform expands. Go to Effect > Amplify and the dialog window will pop up and show you the maximum amount of amplitude you can apply without clipping. Now we have some headroom to adjust the amplification. Voila! See the envelopes disappear? See how the peaks have become much lower? This can be done easily by clicking Tracks > Mix and Render. Now that we’ve smoothed out as many peaks as we could, and our envelope has been adjusted to our liking, we can move forward with Mixing and Rendering our changes. I’ll be working on the (3) peak areas outlined above in Step 1. Now that we’ve smoothed out the first peak, we’ll need to repeat this action for the tallest peaks found within the remainder our audio.

If the blue line moves in toward the center when adding points, simply click and drag the marker point back to the edge to maintain the track’s original amplitude.

If you ever need to remove a marker point, simply drag it past the outside of the waveform / blue line and it will disappear. You are welcome to use more to create a smoother fade if desired. Try to make your marker points / envelope look like this:įor basic edits like this, I use one marker point on either side of the peak to hold everything else in place, and a single marker point to reduce/smooth the peak. Going back to my Envelope Tool, I’m going to use my mouse to move along the outer blue line that appears on either the top or bottom of the waveform when the Envelope Tool is selected and create several marker points used to hold the envelope constant on the outer edges and to smooth out the peak in-between the “hold” points.Ĭlicking once on the blue line will create an envelope marker point and dragging the point toward the center of the waveform will decrease the amplitude/volume of the affected area. Once zoomed in, the waveform should appear something like this: I like to click with the Selection Tool as close to the peak as possible and use the keyboard shortcut ⌘+1 to zoom, but Audacity offers several different ways of zooming, so it’s up to you. To begin using the tool, we’ll need to zoom in on each individual peak we’ll be smoothing out. Notice how new blue lines appear across the top/bottom of the waveform? See the new white area surrounding the middle part of our waveform? Those are normal, and will appear / disappear whenever the Envelope Tool is selected / deselected. Here, we’ll use the Envelope Tool, which can be seen in the following screenshot: How do we do this without using the traditional fade in / fade out commands, while creating something a bit more “custom” to our needs? I’m glad you asked! Step 2: Envelope Tool Notice how these peaks are either right at the edge of the top/bottom of the 1.00 / -1.00 spectrum, or are approaching the outer limits, steadfast? In order to boost our levels globally, these peaks will first need to come down in size. In this next screenshot, I’ve identified several of the loudest areas/peaks, which are preventing me from applying a global amplitude increase, as these areas would be pushed beyond the audible spectrum and would sound (even more) terrible if boosted as is. Listen to the original, un-edited audio seen above Step 1: Open Audioįor today’s example, I’ve created a short, spoken-word track of me just talking (poorly) into the built-in microphone on my MacBook Pro. In today’s post I will share with you a VERY easy way to bring down the highest points of your audio, re-render the track and boost the amplitude as much as possible without creating distortion (clipping). Not too long ago I purchased a new microphone for doing voiceover work for AudioAcrobat and a couple other projects I’ve got up my sleeve, and needed a way to bring down the amplitude of certain peaks within my recordings without doing a hard fade in / fade out…
