Level balancing is the process of adjusting the volume levels of individual tracks in a mix to ensure that they are all heard clearly and in proportion to each other.

De-essing is a technique used to reduce harshness and sibilance in vocals by attenuating the high-frequency range where these sounds are most prominent.

Compression is used to reduce the dynamic range of a track by attenuating the loudest parts and boosting the quietest parts, resulting in a more consistent and polished sound.

Panning is used to create a sense of space and depth in the mix by placing individual tracks in different positions across the stereo field.

Mastering is the final step in the mixing process where the overall sound of the track is polished and optimized for streaming platforms.

Shelving EQ is a technique used to boost or attenuate the low or high end of a track by applying a gradual slope to the frequency response.

A limiter is used in mastering to prevent clipping and distortion by limiting the peak levels of the track.

Multi-band compression is a technique used to control the dynamics of a track by applying compression to different frequency bands independently.

A stereo widener is used to create a sense of space and depth in the mix by increasing the stereo width of individual tracks.

Parametric EQ is a technique used to reduce muddiness in the low end of a track by attenuating specific frequency ranges where muddiness is most prominent.

A de-esser is used to reduce harshness and sibilance in vocals by attenuating the high-frequency range where these sounds are most prominent.

Sidechain compression is a technique used to create a pumping effect in a track by using the signal from one track to control the dynamics of another track.

A reverb is used to create a sense of space and depth in the mix by simulating the natural reverberation that occurs in a room.

Shelving EQ is a technique used to boost or attenuate the high or low end of a track by applying a gradual slope to the frequency response.

A delay is used to create a sense of space and depth in the mix by simulating the natural delay that occurs when sound travels through a space.
