Using LR Effects as MS (+ free Encoding/Decoding racks)

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.

Before & After Analysis = Awesome

We could all use less “hmm, i wonder what this is doing exactly?” and more “aha, i understand exactly what that is doing!” moments in our lives, am i right?

Well, perhaps you have everything sorted out with absolutely perfect mental clarity at all times… but nobody that i know of does. The built-in perceptual capabilities of human bodies have limitations. Consequently, methods we can use to uncover and keep track of finer layers of detail to our perceptual input than normally possible can be quite useful for stepping outside our our usual—highly subjective and somewhat amorphous—human frame of reference.

When i look back on the last few years of my audio production journey, the one software tool which has proven the most valuable (well other than Ableton Live, obviously) has been a particular analyzer plugin. This blog post is definitely going to be promoting that specific product, so i’d like to point out that i am not affiliated with the developer in any way and this post is not endorsed. i just… really love it.

The plugin in question is the IQ Analyser by HOFA.

Continue on for an brief overview of a couple of innovative qualities that make this tool stand out, interspersed with some philosophy about the general usage of spectral analysis.

The IQ Analyser has lots of awesome attributes, but what makes it particularly extra nifty to me are two particular traits: The “Energy” Spectrum and “Difference” Mode.

An Alternative to True Peak Limiting: Not

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.

Implied Curvature

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?

Skip Plugin Scan to Load Ableton Live Faster

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.

All About Ableton’s Gate—A Pragmatic Guide

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.

New Pack: “Subterrestrial”

Hi!
PerforModule has got a new Ableton Live pack available.

What makes this one special? Well, it’s the first in a proposed series of “Binaural Textures” instrument packs, which include the unique feature of built-in binaural surround panning.

Binaural Surround Panning? What the heck is that!?

(listen to the video below on headphones to hear for yourself)
