You want the compressor to let go just as soon as the next snare hit occurs. For example, if the release time is set too short and the compressor is cycling between active and non-active, your dominant signal — usually the bass guitar and bass drum — will also modulate your noise floor, resulting in a distinct "breathing" effect. You can avoid this by using a multiband compressor such as the. I'm trying to just compress those peaks so I want the compressor to react quickly. It's also a popular choice for bringing out excitement in room mics. Only when a level passes above the threshold will it be compressed. Design templates, stock videos, photos & audio, and much more. Listen to how it sounds thicker than before. 1. Try starting with a moderate to medium ratio of between 2:1 and 5:1. This can be simply due to the type of compressor being used, but often it’s the difference in tone between the peaks and the troughs of an instrument (if you reduce the peaks relative to the troughs, the tone will change). Audio compression is one of the most misunderstood processes. As you can see in the diagram, a “soft knee” allows for a smoother and more gradual compression than a “hard knee.”, This refers to the time it takes for the signal to become fully compressed after exceeding the threshold level. A slower attack time is usually more desirable to get the beater through, although there are some times where you might want a more earthier, rounded bass drum tone. Learning how to apply compression will help you achieve more polished mixes. Other times you need to flatten out specific parts by heavy compression across the board or just subtle peak compression to make things fit. Adobe Photoshop, Illustrator and InDesign. Compression is a tricky subject for many, and there is no “one” great method for any situation. If it sounds good, it is good. FET If a cycle at 100 Hz lasts 10 ms, then a 1 ms attack time will have time to alter the waveform, which will generate distortion.). It is a common practice and recommendation to apply “gentle” compression at different stages throughout the recording/mixing/mastering process rather than applying excessive compression at just one point. Faster attack times are usually between 20 and 800 us (microseconds) depending on the type and brand of unit, while slower times generally range from 10 to 100 ms (milliseconds). You will find a wide range of ratios available depending on the type and manufacturer of the compressor you are using. Release times will be considerably longer than attack times, generally ranging anywhere from 40-60 ms to 2-5 seconds, depending on which unit you’re working with. Chapter 13 Basic Audio Compression Techniques 13 1 ADPCM in Speech Coding 13.1 ADPCM in Speech Coding 13.2 G.726 ADPCM 13.3 Vocoders 13 4 Further Exploration 13.4 Further Exploration These compression ratios are expressed in decibels, so that a ratio of 2:1 indicates that a signal exceeding the threshold by 2 dB will be attenuated down to 1 dB above the threshold, or a signal exceeding the threshold by 8 dB will be attenuated down to 4 dB above it, etc. I hope some of the examples above have shed some light on the different ways you can use compression. 4. Mastering Elements Part 1: The Buss Compressor. Creative Compression With Guitar and Bass. Anything you want to share with your fellow readers about any trick's you've discovered? The type of compressor you choose will also play a large role in the overall sound of the effect. In many types of popular music, there will be a bass line with a fairly constant signal level. Finally, speed up your attack time gradually until it gets noticeable and then back it off slightly. Looking for something to help kick start your next project? Transform coding dates back to the late 1960s, with the introduction of fast Fourier transform (FFT) coding in 1968 and the Hadamard transform in 1969. If you have a low level track you need to compensate the threshold accordingly. Inspired by the great reception I received from 6 Frequencies and How to Spot Them I decided to do something similar with different types of compression. If we want to reduce the snap from the beater and give it a mellower and rounder sound we would make sure our compressor had a fast attack. Share ideas. Some compressor types will have faster “attack” and “release” times than others, and some will have more “coloration” or “vintage” vibe based on the internal components. These are certainly not rules, but hopefully these tips will help you feel more confident when using this extremely powerful, but easily misused recording tool. Because of this, tube compressors exhibit a distinct coloration or "vintage" sound that is nearly impossible to achieve with other compressor types. 3. If you use compression to try to counter a loud peak — like a horn part —the entire mix will drop at that point causing the bass line to dip and create the “pumping” effect mentioned above. Here is the dry vocal track without any compression: Listen to how a really high threshold affect the whole track, making the vocal track sound flat. Follow him on Twitter and circle him on Google+ for more tips and tricks. You don't want to dull the attack of the snare drum so put the attack all the way fast and then slowly pull the attack slider back until the “snap” of the snare hit comes through. Host meetups. More specifically, it is the time it takes for the signal to go from the compressed — or attenuated — state back to the original non-compressed signal. There are just a few peaks in the vocal track that jump out. Depending which compressor you're using, and whether it’s a hardware unit or a plug-in, there are some common parameters and controls that you will be using to dictate the behavior of the compression effect. He has been writing about music production since 2008. Alternately, over-compressing your music can really squeeze the life out of it. Learn essential functions of popular tube and solid-state compressor varieties, and creative uses for your productions. Compression is a tricky subject for many, and there is no “one” great method for any situation. 12 Days of Savings Up to 60% Off - Ends November 30th! Some compressors will provide meters that can be put into “GR” or “gain reduction” mode to visually indicate the total attenuation in dB, allowing you to accurately apply the correct amount of output gain. Compression is subjective depending on what you are workings with. In many types of popular music, there will be a bass line with a fairly constant signal level. If you’re going to compress an entire mix, use caution. It’s important to use compression with purpose. Have fun and experiment. Fast attack times may create distortion by modifying inherently slow-moving low frequency waveforms (Ex. If you want more examples for different instruments check out my latest Premium tutorial, Creative Compression With Guitar and Bass. $199.00. A snare drum that breathes in time with the track pushes the drum sound forward and just makes it sound tighter. If the threshold level is set at say -10 dB, only signal peaks that extend above that level will be compressed. As always, let your ears be the final judge. The ratio is fairly high since we want to flatten those particular vocal phrases and the compressor is set to Peak. Optical Now, if we want to compress it in time with the track we are really only using the release parameter of the compressor. You can use the output gain to “make-up” for the attenuation done by the compressor. Tube By turning the threshold all the way down so it affect the whole signal makes each and every phrase compressed. A ratio of 1:1 (one to one) is the lowest and it represents “unity gain”, or in other words, no attenuation. Check out his blog Audio Issues where he has written guides on EQ, building a home studio and recording vocals. The lyrics “Running from our fears” kind of jump on top of the track instead of blending in, so we must be careful when we're applying compression to them. Then set your output gain to compensate for the 5 dB attenuation. Experiment with using dramatic compression as an effect. Below are some of the basic elements of compression.
