Equalizer is available in the Creator tier and Pro tier.
The equalizer is used to adjust the strength of specific frequencies in an audio clip. This can be used to selectively adjust the bass and treble, for example, depending on the intent.
The presets menu provides quick access to common equalization tasks, such as high pass, low pass and bass boost.
The Master Gain control is used to control the volume of the clip. This operates separately to the volume property of the clip and should be used to set the base volume of an audio clip. The volume property can then be used to fine tune volume and mix clips over time.
Recorded audio will often have a low gain when imported. To set your gain to a satisfactory volume for standard playback on typical equipment, you can observe the default gain using the audio meters. Playback the clip and note the peak audio level, as displayed in the peak boxes. You can then make the appropriate adjustment to the Master Gain. For example, if you have a dialogue track which has been recorded with a peak of -18dB, making it rather quiet in the mix, you can set the Master Gain to 9.00dB in order to raise the overall gain to -9dB. This results in louder audio while still leaving headroom to adjust the volume if required.
