Compression is probably the most used tool in the production environment, but the least understood. Although it can help, it can remove the punch from your track. To use compression correctly we first have to understand how it works. In it’s most simple explanation, compression is an automatic volume control. It can reduce the difference the difference between the loudest and softest audio signal. You can use it to tighten a bass track. Make a drum track more punchy. you can also use the popular side-chain gate effect. Rather than just talk about this, I found a great video that talks about a compressor.. Enjoy:
