For this tutorial we’re going to posit an example scenario: a way to achieve the common practice of narrowing the bass content of a stereo track by scooping out the S channel’s low end—but this time, using analog gear instead of plugins. But what if we don’t have any M/S gear? Not to worry.Continue reading
True Peak Limiting is a method by which a limiter adjusts for how the digital waveform will be reconstructed by playback systems which can result in actual peak levels above 0dB even when the digital peak level is technically shown at below 0dB.
Basically the way intersample peaks occur is that the quantization points of a digital waveform can at times imply a curve between them which goes up a little bit higher than those actual sample points, resulting in a louder-than-expected actual peak level coming though.
To imagine it, just draw two dots in your mind, and then instead of drawing a straight line between them, draw a slightly curved line. The two dots are at a height of zero, and the curved line connecting them is bumping a little bit above zero. See?
Filter Circuits – Drive
We know that the new(ish) circuit models for Ableton Live’s Auto Filter effect add some tasty analog-modeled distortion, but what about their characters? Which of the circuit models adds the most aggressive distortion?Continue reading
This is just a quick, simple tip.
If it takes forever to scan plugins every time you open Live (due to certain poorly-coded plugins taking longer than others and bottlenecking the process), you can set it up to skip plugin scan. Keep in mind that if you do this, you’ll want to perform a manual scan (from preferences) any time you install or update any new VST plugins.
How to do it?
Add “-NoVstStartupScan” to your options.txt file
But how to do that?
To familiarize yourself with Ableton’s options.txt, i will point you towards sonicbloom.net’s awesome article and series of videos on the topic.
That’s it! Live will no longer do a scan every time it opens.
Ever since i applied this option, the stupidly vast size of my plugin collection doesn’t adversely affect my workflow. Live startup time is way snappier. When i occasionally buy or grab a free plugin, i just run a scan after installing it. Every once in a while you might have to do a “deep” scan (hold alt while clicking the scan button) if something doesn’t show up when it’s supposed to.
Note that from Live 10.1 onward, the plugin rescan button is located in the new dedicated plug-ins tab in Live’s preferences, rather than under file/folder, as previously.
Hopefully this nifty tip is inapplicable to you, as that means your plugin scan is not bloated. However, for those of you that are having issues with slow startup of Ableton Live (or in case it eventually becomes an issue) this may be a viable solution.
I found some old notes i had taken (for my own reference) about the parameters of Ableton’s Gate audio effect plugin and figured others could use the info as well, so i’ve polished ’em up, expanded on them a bunch, and dropped them here for you.
I’ve found that getting to know exactly how each parameter works with gate plugins leads to attaining desired results exponentially easier, and in particular learning how the more exotic parameters such as lookahead and hysteresis work facilitates sophisticated gate optimization.
There are not many controls for digital plugins where i prefer stepped options as opposed to continuous values, but the Q factor of EQ slopes is one of those that generally i do. Not really sure why i prefer them that way; i suppose there are a few reasons.
Regardless, i made myself (and you!) up a nifty spreadsheet of “Go-To Q Values”, based on logarithmic steps between the basic Q value (0.70607) and the minimum or maximum ranges. These Q values are optimized for Ableton Live’s EQ Eight, but can be applied to most any parametric EQ, when you want no-brainer go-to Q values to fall back on.
This workflow enhancer is really simple.
Just disable VST plugins during times in tracks when they are not being used.
Automate the nifty device activator (aka “on/off switch“) of a device (or a rack of devices) to shut off during times of silence. Set the automation to switch on a little bit before audio starts, and to turn back off a bit after the audio is completely silent again.Continue reading
So there’s this issue with fading between chains in a rack in Ableton Live which i haven’t heard much mention of. Perhaps you’ve noticed it?
Say you have a rack with two chains, let’s call them “A” and “B“.
Using the Zone Editors in the Chain Selector Editor of the rack, we’ll place A on the left (full at 0), fading out the other direction. Vice versa for B, placing it on the right (full at 127) and fading out towards the left.
Now let’s map the Chain Select Ruler to the first Macro.
Macro 1 will now give us a nifty fader knob between whatever processing we place on chain A versus whatever we place on chain B.
Nice …except for the problem.Continue reading
Kind of like every human being has a height value, every audio clip has a peak level value. So what can we do with that information, beyond knowing that going above 0dB usually isn’t advised? In our eternal quest for ultimate audio quality, the inclination can be inherent to record loudly—as close to 0dB—as possible, and thereafter maintain that peak level. We fear that by mixing with track levels that are too quiet, we might be losing fidelity, some harmonic detail in the saturation floor or something.
While it is true that recording analog signals as loudly as possible without signal clipping to begin with will indeed minimize noise floor, the benefits reaped by maximizing peak level for individual tracks tapers off as you get closer to zero. At what peak level are audio sources louder than they really need to be? At what level are they too quiet, that they might need to be boosted excessively later? Using an algorithm based on the energy of how sounds stack together, i devised a set of go-to ranges for peak levels based on track counts. Since peak levels can vary fairly wildly based on content, you are given minimums and maximums (instead of single target values). Juicy details ahead… Continue reading
Having recently acquired a new custom-built PC, various steps implemented to optimize its performance and usability were taken note of. While not an expert in such things, i figured to share these tips in case they may prove useful. Keep in mind that this guide is presuming that you already dabble in audio production and are upgrading to a new—from an existing—system.
