Volume houses volume and other audio related settings of a selected item on the Timeline. From left to right, it consists of Master Volume, Background, Compressor, Stereo Pan, and Pitch.
The Master Volume setting is located on the far left. Volume of the selected item can be adjusted between 0% and 200% of the original volume. Tapping the Volume icon above the Master Volume slider toggles mute for the track.
The Background slider reduces the volume of clips marked as background by turning on Background.
The Compressor reduces the dynamic range of the audio, making quiet noises louder and loud noises quieter, effectively normalizing the track. It’s useful for recordings where the subject was not a constant distance from the microphone as it compensates for differences in volume level. If used on several clips, they will more or less overall match in volume afterwards. It can be toggled between On and Off. Default setting is Off.
Stereo Pan adjusts the stereo mix of the track with two separate slider. The top slider controls where the left channel is output, and the bottom controls where the right channel is output. By default, the top slider is placed 100% left, (so the source media left channel is output to the left channel) and the bottom slider is placed all the way to the right.
However, various effects can be achieved by manipulating these sliders:
- Swap left and right channels by setting the top slider all the way right, and the bottom slider all the way left.
- Convert stereo audio to mono by setting both sliders to the center.
- Adjust the left and right balance by slightly adjusting both sliders.
Pitch allows the raising and lowering of the overall pitch of the selected item’s audio.
