How can compression improve the quality of music mastering?

1 What is compression?

Compression is a process that reduces the dynamic range of an audio signal, which is the difference between the loudest and the quietest parts of the sound. By applying compression, you can make the quieter parts louder and the louder parts quieter, creating a more consistent and controlled level. Compression can also affect the tone, color, and character of the sound, depending on the settings and the type of compressor you use.

2 Why use compression in mastering?

Mastering is the final stage of music production, where you polish and optimize your mix for different platforms and formats. Compression is an essential tool in mastering, as it can help increase the perceived loudness and impact of your music without clipping or distorting the signal. It can also smooth out any unwanted peaks or dips in the frequency spectrum, and enhance the overall balance and cohesion of the mix. Compression can add warmth, punch, or brightness to your sound based on its characteristics and settings. Additionally, it can glue together the different elements of your mix, creating a more unified and professional sound.

3 How to use compression in mastering?

When using compression in mastering, there is no single formula that works for all genres, styles, and intentions of music. However, there are some general guidelines to follow. For example, use a high-quality compressor that suits the genre and sound. A low ratio (2:1 or less) and a high threshold (-10 dB or more) should be used for gentle and subtle compression, while a slow attack (10 ms or more) and fast release (100 ms or less) will preserve the groove and rhythm. Additionally, a low-pass filter or side-chain input should be used to exclude the low frequencies from being compressed. Finally, stereo or mid-side compression can help control the width and depth of the mix.

4 What to avoid when using compression in mastering?

Using compression in music mastering can improve the quality of your tracks, but it can also degrade it if you misuse or abuse it. To avoid common mistakes, make sure your mix is as good as possible before applying any compression. You should also avoid the loudness war and use your ears and meters to find the optimal level of loudness for your music. Moreover, always listen to the before and after of your compression, and compare it with other tracks in your genre and style. Additionally, listen to your music on different speakers and devices to check for any issues or inconsistencies.
