Your RMS display essentially averages out the signal coming through, whereas Peak will display, well, your peaks. Its speed response is the slowest compare to other compressor types. FET (or Field Effect Transistor) compression came about when audio units started to replace large tubes with smaller transistors. Types of Compression. Dealing With Imposter Syndrome: Making It Or Faking It? In this way it’s easy to visualise how an Opto works. These compressors use a photocell as a detector and a light bulb or LED to determine the gain reduction. It's easy to overdue compression on a vocal and squash the natural feel and performance of a well recorded vocal. Because of the less aggressive characterizing of a Mu, it is suited to situations where you need to equal out your source rather than tame your loud transients (in which case a VCA may be more suitable). Kieran is also a guitarist and has performed across the UK. The SSL G Channel Strip is modeled on the classic Solid State Logic SL 4000 console.

Lookahead compression can be achieved with a standard compressor by duplicating the signal onto another track in your DAW, moving the audio back in time, placing a compressor on the original signal, and using the duplicated audio as the sidechain input. Recommended plugins: Certain plugins like Cytomic’s The Glue or FabFilter’s Pro-C allow for a dry/wet blend which can achieve similar results to parallel, but any of your favorite compressors can achieve great results if used properly. Lossy methods provide high degrees of digital compression… Lossy compression can be adjusted to compress audio a lot, or to compress audio very little. Because of this, tube compressors exhibit a distinct coloration or "vintage" sound that is nearly impossible to achieve with other compressor types. The G Channel Strip can take a little while to get used to but the results it produces are worth the time getting to grips with it. Parallel Compression; Parallel compression allows you to get the best of 2 worlds. Meek himself was a pioneer of using compression as an ‘effect’, and aside from having a very colourful history himself, produced some great pieces of gear. I want to encourage you to refrain from applying compression just for the sake of applying compression; if a sound doesn't need it (and many sounds don't), then you don't have to apply it. Compression Vs Limiting: What’s The Difference? As a result, most audio file formats strive for a balance between audio quality and file size. An audio file format is a file format for storing digital audio data on a computer … The Basics of Attack Time on a Compressor. As a general rule compression is used to affect the dynamic range of a track or instrument, however, there are several types of compressors that all operate differently and with different qualities. Also great on the master bus for achieving a boost in RMS. FET, VCA, Optical, and Variable-Mu are 4 classifications of audio compressors. It’s intuitive controls mean it’s also great for sidechaining and parallel compression. Required fields are marked *. ), Recommended plugins: Softube CL1B or Valley People Dyna-mite, Waves H-Comp or API 2500. Lookahead compression essentially analyzes an input signal and applies compression before the signal is audible, allowing one to tame transients in a unique way. Whether you’re using a physical piece of outboard gear or a plug-in emulation, the sound of compression will vary type by type. Fast forward to the modern-day and you’ll be hard pushed to find a commercial track without compression on. Get 65% Off Mix Essentials.

The second post in our audio compression series, this post is all about the four common types of audio compressors. compressioncompressorstypes of audio compressorsvocal compression. The speed of light is extremely fast, but an Opto compressor is actually quite slow and smooth. This model includes a ‘ShMod’ (Shape Modulation) function which allows you to tweak the attack curve giving you an added level of customization to the compressor’s behavior. Here's information on some of the ways that you can use the many different types of compression to enhance your productions. 4 Types of Audio Compression Compressors take on many forms in music, and these vary in popularity depending on genre. Generally speaking, audio compression, be it lossy or lossless, is the process of compressing or shrinking down the size of an audio file and … Opto Compression. It turned out however that by compressing this signal the sound became punchier and sounded louder. Opto. Essentially, it involves using one signal to apply compression upon a another. The slower attack time on a Variable Mu can really help ‘glue’ your track together which can create a much more balanced and smooth mix. Recommended plugins: Softube FET compressor, Waves C1 Compressor with Sidechain. An Optical Compressor (or Opto-Compressor) uses a light source to control how much gain reduction is applied. This type of compression relies on the tubes themselves to control the gain reduction and therefore the process tends to be quite smooth. Here's information on some of the ways that you can use the many different types of compression to enhance your productions. Recommended plugins: FabFilter Pro-L, Waves L2, PSP Xenon. Be aware of delay compensation settings in your DAW to avoid unwanted phase issues. 1. Both downward and upward compression reduce the dynamic range of an audio signal. Technically a VCA isn’t actually an amplifier, rather it uses an attenuator to reduce the volume when it’s fed a certain level of voltage. You wouldn’t get a great result trying to control short, sharp transients in the same way you would with a VCA for example, but you would be able to create a smooth compression at much higher ratios. Opto. Downward compression reduces loud sounds over a certain threshold while quiet sounds remain unaffected. Aside from deciding HOW to use compression, as you delve deeper, you’ll start to think about WHAT compressor to use. Multiband Compression/Limiting Multiband compression al. Ian Vargo is a Producer, Mixer and Audio Professor based in Los Angeles. Because of this, an Opto compressor works off the average signal being received. If you’ve ever seen a ‘Peak’ and ‘RMS’ option in your DAW, think of an Opto as a compressor that reacts best to an RMS signal. Types of Compression. Check out the Joe Meek range of Opto compressors. It’s no secret that dynamic range compression is one of the most important and versatile tools to an audio engineer. The Waves Renaissance Compressor is a smooth all-rounder. Each has different characteristics due to the way their gain reduction circuits react to the signal being passed through them. Upward compression increases the loudness of sounds below a certain threshold while leaving louder sounds unaffected. This can be bought in outboard form or a more cost effective plug in version SSL G channel strip by Waves. They often react more slowly than other compressor types, but this can be desirable. It’s no secret that dynamic range compression is one of the most important and versatile tools to an audio engineer. Parallel compression (sometimes referred to as New York compression) is great for keeping the original, natural sound of a recording, while still enjoying the benefits of a compressed signal. Can be used on individual tracks to tame transients or shape tone just like a traditional compressor. As time went on the sound of compression became more desirable and audio engineers started to utilize this idea of dynamic range compression to improve the sound of their recordings.
