How To Use An Audio Compressor

How do I set audio compression?

Try starting with the compressor set to the fastest attack, fastest release, and highest ratio setting for the compressor. Then adjust the input volume or threshold setting until about 16-24 dB of the audio signal is reduced on average (also known as gain reduction).

Does a compressor make you sound better?

Using a compressor on your tracks is exactly like adding salt to your food! It can make everything sound better, but a little too much can completely ruin your mix. Also, not everything requires salt. Over-compression can be a FATAL mistake for your mix.

When should you compress audio?

1 for compression is that you have an instrument or vocal track that varies too much in level. You want to even the level out either because it sounds better with less dynamic range, or simply to make the task of mixing simpler.

Should I use compression on every track?

Mistake #1: Ignoring the Gain Reduction Meter If you aren’t paying attention to your meter, you may be applying way too much compression, or no compression at all. You don’t need to simply listen and guess. This meter will tell you exactly how much you’re compressing the sound.

Should you EQ or compress first?

Each position, EQ pre (before) or EQ post (after) compression produces a distinctly different sound, a different tonal quality, and coloration. As a rule, using EQ in front of your compressor produces a warmer, rounder tone, while using EQ after your compressor produces a cleaner, clearer sound.

What does a limiter do in audio?

A limiter allows you to bring up the level without allowing the peaks to clip. Modern mastering limiter plugins are extremely precise in catching peaks and won’t allow anything to pass through over their set ceiling, which is why they are sometimes referred to as “peak” or “brick wall” limiters.

What’s the difference between compressor and limiter?

The difference between a compressor and a limiter is only in the compression ratio used. A limiter is intended to limit the maximum level, normally to provide overload protection. A compressor is used for less drastic, more creative dynamic control, and tends to use lower ratios; typically 5:1 or less.

What instruments should be compressed?

The bass guitar and kick drum are usually the most heavily compressed instruments on a track. They provide the bottom end and usually anchor the song.

How does a compressor make things louder?

Compression makes a quiet portion of the sounds louder relative to a louder portion by reducing the signal strength when the signal strength is high. Often a gain is applied after compression to keep the signal strength up, but this is no different from any other gain.

Do I need a compressor for vocals?

When used correctly, compression is a key ingredient for vocals that sound professional, modern and radio-ready. When used incorrectly, compression can quickly ruin a good vocal recording and make your music sound amateur and over-processed.

Why is modern music so compressed?

The trick being used is called dynamic range compression. It boosts quieter passages of music so that, overall, the music sounds louder. The compression also adds artefacts to the music that can sound nasty.

Why should I use a compressor?

Compressors and limiters are used to reduce dynamic range — the span between the softest and loudest sounds. Using compression can make your tracks sound more polished by controlling maximum levels and maintaining higher average loudness.

Why do my mixes sound dull?

Mixes usually sound muffled due to a build-up of frequencies in the lower mid-range, between 200-500Hz. Applying a narrow EQ cut to selected tracks in this range can help. Using a High Pass Filter (HPF) on instruments that have little presence at these frequencies can also help increase clarity.

What is compression in music mixing?

Compression is used in music to reduce the dynamic range of signals with loud and quiet elements so that both can be heard clearly. Compression is used in music to reduce the dynamic range of signals with loud and quiet elements so that both can be heard clearly.

Do I need compressor for every channel?

The truth is, the best mixers are likely to not use compressors on every track. For pop and rock music, vocals and drums are 99.99% of the time compressed. Distorted electric guitars and synthesizers might not be, though.

Can you mix without compression?

No compression required. Em, but there’s a little bit of a doubt here. Although you can get great-sounding drums without a compressor, some of the records you have heard, whose sounds you may want to emulate, sound different. So you don’t need a compressor.

Where should I put my compressor?

A good rule of thumb is to place any gain-type effects before modulation effects: i.e., compressors and overdrives before delays or flangers. Another one that’s practically set in concrete is to put the compressor before any overdrive, distortion, or fuzz pedal.

Should I come before compression?

When you compress a signal, you are limiting the dynamics, in effect “squashing” the signal together. In some cases, applying compression can also alter the tone of a signal — the low end may come up, the high end may be reduced, and so on. In this case, corrective EQ should be applied after the compression.

What are the 2 types of compression?

There are two main types of compression: lossy and lossless.
