The primary goal of mixing for CD is to create a mix that is balanced, cohesive, and ready for the mastering process, which involves further enhancing and optimizing the mix for its final release.

For CD mixing, the overall RMS level should typically be around -18 dBFS. This headroom allows for mastering engineers to apply further processing and adjustments without causing distortion or clipping.

Boosting the low-end frequencies (below 100 Hz) can add warmth and fullness to a mix, creating a solid foundation for the overall sound.

In the mastering stage, a limiter is used to reduce the dynamic range of the mix and increase its overall loudness, resulting in a more consistent and impactful sound.

Reverb is a commonly used technique to create a sense of space and depth in a mix. It simulates the natural reverberation of a room or environment, adding ambience and realism to the sound.

The primary role of a mastering engineer is to optimize the mix for different playback systems, ensuring that it translates well across various devices and formats, including CD players, streaming services, and mobile devices.

Cutting frequencies in the mid-range (200 Hz - 2 kHz) can help reduce muddiness and improve clarity in a mix. This frequency range often contains unwanted resonances and harshness that can mask other important elements.

Compressors are used in the mixing process to reduce the dynamic range of a signal, making it more consistent and controlled. This can help tame peaks, even out volume levels, and enhance the overall cohesion of the mix.

Panning is a technique used to create a wider stereo image in a mix by placing sounds in different positions across the stereo field. This can help separate elements, add depth, and create a more immersive listening experience.

For CD mixing, the recommended peak amplitude is typically around -0.3 dBFS. This level allows for some headroom to prevent distortion or clipping during the mastering process while ensuring a loud and impactful mix.

Boosting frequencies in the mid-range (200 Hz - 2 kHz) can add presence and clarity to vocals, making them more intelligible and distinct in the mix.

EQs are used in the mixing process to adjust the frequency response of a signal, allowing engineers to boost or cut specific frequencies to shape the overall sound. This can help correct imbalances, enhance clarity, and create a more pleasing sonic experience.

Delay is a commonly used technique to create a sense of movement and energy in a mix. It involves repeating a signal with a slight delay, creating a sense of space and depth. Delay can be used to add rhythmic interest, enhance ambience, and create a more dynamic mix.

For CD mixing, the recommended peak amplitude is typically around -0.3 dBFS. This level allows for some headroom to prevent distortion or clipping during the mastering process while ensuring a loud and impactful mix.

Cutting frequencies in the high-end (above 8 kHz) can help reduce sibilance and harshness in vocals, making them smoother and more pleasant to listen to.
