Pro tip: You can do this with hardware as well by duplicating the track in your DAW, nudging it a few samples earlier on the timeline and sending it to the compressor’s sidechain input while the original track is sent to its normal input. It’s called the ratio because it’s expressed in comparison to the unaffected signal. If the attack time is set too fast, you’ll simply be reducing the “impact” of the individual drum hits by squeezing the initial moments of the sounds too hard.

[CDATA[ Michael Hahn is an engineer and producer at Autoland and member of the swirling indie rock trio Slight. Note: this originally appeared as a guest post on the TwelveThirtyMedia blog. Yes, you can over compress something. Bass guitars can sometimes benefit from compression, especially if the bass is played with a slap style. When you set your threshold, you’re deciding which part of your signal you want to reduce. As the snare hits, there’s an initial peak in your waveform that slowly tapers off. Here is a basic overview of the controls on a compressor: Threshold: this setting allows you to set the minimum level (a.k.a. (No spam! (While this can be ok for a live streaming output or recording, it’s generally not ideal for live reinforcement in the room.) Any setting nearing the 20:1 ratio is becoming a limiter on the signal and not so much of a fine-tuned dynamics control. Compression might just be the biggest one, so make sure you’re getting right. Probably not a desired effect! amzn_assoc_linkid = "b6ca0618eca175dd487665a2b74de668"; Yes, please subscribe me to: amzn_assoc_marketplace = "amazon"; Your Attack and Release are two parts of the same range of control — the timing with which the compressor’s gain reduction starts (attack) and stops (release) acting on your signal. Some compressors will include a limiter function as part of their adjustable parameters. What parts of my signal are becoming more apparently loud? But how your signal gets reduced is determined by the attack and release controls. It doesn't have to be super complicated. Check out this detailed blog post from ShareFaith for a deep dive into compression options and settings. Dynamic range is the difference between the loudest and quietest parts of an audio signal. As you increase the ratio, listen carefully for when the gain reduction effect becomes apparent. It’s the essential element behind every good mix. Compression in music is the process of reducing a signal’s dynamic range. So get back to your mix and squash something just right! When you’re searching for the right compression settings, actively listen for changes in dynamics as opposed to shifts in timbre. When it comes to practicing with compression, the bypass button can be your best friend. There are four primary settings on a compressor: threshold, ratio, attack, and release. A waveform with good dynamics will have many transients as certain sounds hit and then decay in your composition. All audio signals below this threshold will be ignored and passed through, while all signals above the threshold will be affected by the remaining compressor settings. Setting the threshold lower will apply the compressor’s gain reduction to a greater portion of your signal. ), Enter your name and email to receive weekly updates, tools, and tips to help make your sound great. amzn_assoc_textlinks = "B0002BACAK,B00IH1K09A,B0006NMUGI,B0002E51C6,B000Z08TOE,B0002BACB4,B009YRL4OG,B012TAWYHU,B0002GZOQC,B0000AQRST,B000065BPB,B000TZVCWG,B003BZWR4S,B0002BACAK"; + Welcome to Soundfly! This is at no additional cost to you. It’s easy to think faster attack settings sound better when the drums are soloed, but in the context of the track, the drums will disappear if the the transients have been limited too aggressively. Is it moving in time with the music? Ratio: this controls the fundamental dynamics of the audio signal coming in above the threshold level setting. Your compression should preserve the character of them, not destroy it. If we set the threshold to -24db, the compressor will not affect everything quieter than that. Audio Geek, Drummer, Pilot, Author, and someday I'll learn to play the hurdy-gurdy! I wish I could do that too. It’s an important concept. And I don’t want to mislead you. It’s an important concept. When you use a compressor to change those dynamics, the mix engineer becomes part of the musical performance. Depending on the playing style, you may get away with mild compression, but someone who goes from finger picking to slapping is going to need to have the compression turned way up. amzn_assoc_tracking_id = "great0f4-20"; First off: a good rule of thumb for compression is “do no harm.”. A lower first number in your ratio will give you gentle compression you might apply to an entire mix, while a higher first number will give you an intense squashing effect. Remember, it’s what sounds good in the final mix that counts! For example: imagine a whisper and a scream on the same audio track. Is it a corrective or aesthetic change? Attack & Release: these two parameters are used to adjust how quickly or slowly the compressor function is applied. Stop just before it becomes obvious and begins to negatively impact the sound. A fast attack and fast release time can make the audio sound as though it is pulsing, since the compression is engaging and disengaging very rapidly.
