Common Tools in Industry

Equalizer. A device or software used to manipulate the frequency response of an audio signal. (eg: FabFilter Pro-Q 3)
Compressor. An audio processor used to reduce the dynamic range of an audio signal. (eg: Waves C6)
Limiter. A type of compressor that prevents any signal above a certain threshold from passing through. (eg: iZotope Ozone 8)
Multi-band Dynamics Processor. A tool that divides an audio signal into separate frequency bands, allowing for independent dynamics processing of each band. (eg: Waves SSL G-Master Buss Compressor)
De-Esser. A tool used for reducing excessive sibilance in a vocal track. (eg: Waves DeEsser)
Stereo Imager. A tool used to widen or narrow the stereo image of an audio signal. (eg: iZotope Ozone 9)

Common Important Terms

Dynamic Range. The difference between the loudest and quietest parts of a track. A mastering engineer will work to ensure the dynamic range of a track is balanced.
Equalization (EQ). The process of using filters to adjust the frequency spectrum of a track. EQ is used to make certain elements of a track stand out or be more prominent in the mix.
Compression. The process of reducing the dynamic range of a track by making louder parts quieter and quieter parts louder. Compression is used to make a track sound more consistent or to make certain elements stand out.
Limiting. A form of compression used to make the overall volume of a track louder without affecting its dynamics. Limiting is often used to make a track as loud as possible without distorting it.
Stereo Imaging. The process of creating a stereo image, or the perception of width, depth, and height in a track. Mastering engineers can use stereo imaging techniques to make certain elements stand out or be more prominent in the mix.
Loudness Normalization. The process of adjusting the loudness of a track so that it can be played back at a consistent level on different playback systems. This is especially important for streaming services, which have their own loudness standards.
