Common Important Terms

Mastering. The process of preparing and transferring recorded audio from a source containing the final mix to a data storage device such as a CD, DVD, or digital audio file. Mastering typically involves adjusting the levels and equalization of multiple tracks, as well as applying effects such as compression, limiting, and reverb.
Mixing. The process of combining and blending multiple audio tracks into a single recording. Mixing involves adjusting the levels, panning, and equalization of each track to create a cohesive whole.
Audio engineering. The practice of manipulating sound waves to create a desired effect. Audio engineering includes mixing, mastering, and other related activities.
Equalization (EQ). The process of adjusting the frequency response of an audio signal to achieve a desired sound. Equalization can involve boosting or cutting certain frequencies to create a desired sonic effect.
Compression. The process of reducing the dynamic range of an audio signal by reducing the level of its loudest parts. Compression can be used to create a more consistent sound across multiple tracks, or to make a track sound louder.
Limiting. The process of applying an upper threshold to an audio signal so that its loudest parts do not exceed a certain level. Limiting is similar to compression, but with a much more drastic effect.
Reverb. The effect of simulating an environment by adding echoes and reverberations to an audio signal. Reverb is often used to make a track sound like it was recorded in a specific space or room.
