Techniques Used in Mastering Music

Mastering is an essential part of ensuring that music is given its best treatment before distribution. Techniques used in mastering music are numerous and have evolved greatly over the years. This section takes an in-depth look at some of the most common techniques used in mastering music.

Equalization (EQ)

Equalization or EQ is an essential tool used in mastering music. Equalization involves the use of filters to adjust the tonal balance of the music. Different filtering techniques are used to adjust the tonal balance of the music. Some of the filters include; low-pass, high-pass, and mid-boost.

Low-pass filters are used to remove high frequencies from the music. They are used mainly to remove hiss sounds and sibilance that may have been introduced during mixing. High-pass filters, on the other hand, are used to remove low-frequency sounds that interfere with the clarity of the music. Mid-boost filters are used to give emphasis to the mid-range frequencies of the music.

Equalization is a delicate process that requires a lot of expertise. One small change can affect the whole sound of the music. When used correctly, EQ can make a significant improvement to your tracks making the music sound fuller, richer and balanced.


Compression is another technique used in mastering music. Compression is the deliberate reduction of the dynamic range of the music. Dynamic range refers to the difference in volume between the loudest and softest parts of the music. Compression is used to ensure that the audio levels of the music are consistent, enhancing the audio quality in the process.

It works by reducing the audio levels of loud sections of the music, while increasing the audio levels of soft sections of the audio. This is done in such a way that the volume of the audio remains the same while improving the quality of the audio. The audio is more consistent with compression applied but care must be taken not to overcompress the audio as this can kill the overall character and natural sound of the music.


Limiting is an audio technique used to prevent audio levels from exceeding a certain threshold. It is a form of compression that is used to ensure that the loudest parts of the music remain under control. When music levels start peaking above the limits, it can cause distortion and even damage people’s hearing when listening to it through earphones or loudspeakers.

Limiting involves setting a threshold that specifies the maximum level of audio allowed. Any sound that exceeds the threshold is reduced, making the audio more consistent and safer for listening. It is essential to note that over-limiting can destroy the tonal balance of the music and cause it to lose its natural sound.

Stereo Enhancement

Stereo Enhancement is another technique used in mastering music. It involves adjusting the stereo width of a track. Wide stereo signals can add depth and width to the audio, making the music sound more spacious. The relevant technique is used to create a more pleasant experience for the listener.

Contrary to popular belief, the stereo mix is not suitable for all genres. For example, heavy metal tracks and rap music tend to benefit from the mono mix, which gives them a more powerful sound. Stereo enhancement should be used carefully as it can cause phase cancellation and make the audio sound thin and weak.

Mastering at High Resolution

Mastering at High Resolution is a technique used in mastering music which promotes the creation of high-quality audio. Higher resolution translates to better audio quality, as it allows sound details that might have been missed during mixing to be detected. High-resolution mastering involves working with audio samples that have a resolution of at least 24 bits, which is higher than the 16 bits used in CD mastering.

Mastering at a higher resolution increases the dynamic range and depth of the audio. Mastering at high resolution also improves the overall sound quality of the music, leaving the end-users staying for more.


Mastering is an important step in ensuring that your music sounds its best before distribution. Techniques used in mastering music are numerous and varied, and they all play an important role in the improvement of audio quality. Equalization, Compression, Limiting, Stereo Enhancement, and Mastering at High Resolution are just a few of the techniques used in mastering music. It is imperative to remember that when used properly, these techniques can enhance the audio experience, leaving the end-user craving for more.
