Mastering for CD and DVD involves a series of processes aimed at optimizing the audio quality and ensuring compatibility with the playback capabilities of CD and DVD players.

Pitch correction is typically not a common step in the mastering process for CD and DVD, as it involves altering the fundamental frequency of the audio, which can affect the overall musical integrity.

Equalization is used in mastering to adjust the overall tonal balance of the audio, allowing engineers to fine-tune the frequency response and create a more pleasing listening experience.

Multiband compression, stereo compression, and limiting are all commonly used in mastering for CD and DVD to control dynamics, enhance loudness, and prevent distortion.

Dithering is a process used in mastering to reduce quantization noise, which is a type of distortion that can occur when converting audio from a higher bit depth to a lower bit depth.

MP3 is a lossy audio format that is not typically used for mastering audio for CD, as it can introduce artifacts and reduce the overall audio quality.

Index points are used in CD mastering to mark the beginning of each track on the CD, allowing CD players to accurately navigate and play the tracks.

48 kHz is a common sampling rate used for mastering audio for DVD, as it provides a good balance between audio quality and file size.

Red Book defines the physical format of the CD, including the disc structure, track layout, and error correction methods, while Yellow Book defines the audio format, including the sampling rate, bit depth, and channel configuration.

Pre-emphasis is used in CD mastering to increase the high-frequency content of the audio, which helps to compensate for the inherent roll-off of high frequencies that occurs during the manufacturing process.

Vinyl is not a common type of CD mastering lacquer, as it is typically used for mastering vinyl records.

A PQ sheet is used in DVD mastering to define the chapter points and navigation structure of the DVD, allowing DVD players to accurately navigate and play the content.

MP3 is a lossy audio format that is not typically used for mastering audio for DVD, as it can introduce artifacts and reduce the overall audio quality.

A DDP image is used in CD mastering to create a single file that contains all the necessary data for CD replication, including the audio tracks, index points, pre-emphasis settings, and PQ codes.

Shellac is not a common type of DVD mastering lacquer, as it is typically used for mastering vinyl records.
