This is a Java-based audio compression tool which uses a real-time audio compression and brick-wall limiter technology. Release times should allow the compression to fall off naturally at the end of a sound. So originally, the compressor/limiter was created to reduce the dynamic range of our audio signal, or to protect that audio signal from over-modulating the radio wave. Too long release time allows audio below the threshold into the compressor. As you can see, there are no attack and release values that are ideal for every track. Use the make-up gain and output control to sit the signal back into the mix without adding any unnecessary noise. Setting the hard/soft knee would depend on the material. A slow release will … Notice how the output lags behind the input due to the attack and release time of the compressor: image source . 7. Release determines how many milliseconds (ms) it takes your compressor to stop attenuating gain once your audio signal drops below the threshold. A fast release will cause your compressor to stop attenuating gain quickly once the signal returns below the threshold. This is the time that the compressor takes to let the signal return to normal once it has fallen below the threshold level. When you get them right, your compressor works almost invisibly, but when those settings are too fast or too slow for the music, compression becomes obvious and intrusive. Typically a release of 80 – 150 ms is enough for most dialog. In this guide I want to teach you exactly how to use a compressor. Short release times cause the compressor to sound like it’s working hard, but long release times sound more natural. Using a fast release along with a fast attack is generally best suited for peak compression. 6. Notice how the compression gradually increases and gradually releases when the signal level crosses the threshold. Too short release times result in clipped, unnatural sounding ends of words. Depending upon the tempo, typical mastering compressor release times might range from 300 to 800 ms or more. Some people find learning how to use compression problematic. A lot of people struggle with this… But there are only really TWO ways to set the release time: Audio compression can be daunting. Audio compression format Creator First public release date Latest stable version Cost Proprietary implementations (codecs) Open-source implementations (codecs) Uses (other than consumer audio) Music reproduction (consumer audio) Telephony app Lossless audio compression Patented DRM; Encoder Player AAC: ISO/IEC MPEG Audio Committee: 1997 ISO/IEC 14496-3 Non-free: FAAC … 8. The release control can really affect the sound of the compressor. Well, it turns out this also had a pretty cool effect on our audio. You can set various parameters for your desired output audio file, including compressor input gain, threshold, ratio, attack, release, gain reduction, make up the gain, limiter threshold, limiter release, limiter gain reduction, and level. Again, usually measured in ms. Output Gain (Make-up Gain) If the audio signal has been compressed, the overall level of the signal will be reduced. Release. This compression would sound alot more natural than using 0ms for attack release times, but whether it is appropriate will depend alot on the style of music and the instrument you are compressing.
