Review: Little Boxes by echo | collective

 

We are still firmly in the month of March which as you all well know is “Intersection of Sound Design and Music” month here on Designing Sound. Today we are talking about Little Boxes from echo | collective. From the horse’s mouth:

 Little boxes is a curated collection of four unique sound sets designed to compliment one another sonically and texturally. These textures move from acoustic to electroacoustic to analog synthesis. The tonal palette of one instrument fits like a puzzle piece into the sound of the others. Each deeply expressive, these instruments compliment each other in both musical and sound design contexts. All of these instruments were miked or directly recorded in MONO, providing for thick, punchy recordings.  The Kontakt instruments break the sounds into stereo however, and push the source material much deeper into its potential.“

 

I find this set of sounds to be wonderful and fascinating. So many sorts of beeps, buzzes, chimes, tings, warbles and zips that feel to have an almost endless spectrum of possibilities. Four different “boxes” make up the five different sets of sounds in this library. My favorite is the Optical Theremin, which contains a wonderful patch “Far Out Synth” that I fell in love with immediately. It has a very calm, soothing and etherial feeling to it I can’t get enough of. However, as much as I would love to go on and on about the many musical aspects of this library I decided to focus this review on using these sounds for sound design specifically.

The Tonebenders Share Plugin Secrets

-1

To round out Plugin Use/Abuse Month here on Designing Sound here are some neat tips and tricks from the 3 hosts of the Tonebenders Podcast.

Timothy Muirhead:

Convolution Reverbs are amazing tools to have in your arsenal of plugins. Unlike conventional digital reverbs which simulate theoretical spaces with arbitrary parameters, convolution reverbs use signal processing to deploy the reverberation of a real, existing physical space. In order to make this magic happen you need both the plugin and an impulse response generated and recorded in the field. Without an impulse response (IR) the plugin alone is not very useful. Luckily, most convolution reverb plugins come pre-loaded with a library of IRs that give you a wide range of reverb settings you can put to use.

The IRs used to create those plugin presets are essentially just audio files – created out on location by either playing back a sine wave sweep or by making a loud high-transient noise that covers a large swath of the frequency spectrum – by firing a starter’s pistol for example – and recording the result. The convolution reverb calculates the relationship between the source sound and the resultant reverb created in the space. It can then apply that mathematical relationship to any other sound you patch through the ‘verb. The results are very realistic and natural-sounding reverb treatments. In post-production applications, a convolution reverb can be a life-saver for matching ADR with location audio, and making sound effects feel like they inhabit the same space as the actors. Yet for all the help they offer in making things sound realistic, convolution reverbs can also be employed to make things sound very other-worldly as well.

Every so often I find myself looking for a sound that I can not quite find in my library or even begin to figure out how to tackle. This dilemma is the sound designer’s version of writer’s block. I’ll be banging my head against the wall as my progress grinds to a halt. One strategy I resort to in this situation is to pull up a convolution reverb plugin and try to get creative with the impulse responses I load up. There are some interesting IR’s available; the precise acoustics of the world’s most revered performance spaces are there in your preset menu, alongside IRs recorded in caves, tunnels, and plastic garbage cans. Any space where an IR can be recorded can then be emulated by a convolution reverb.

There are obviously very scientific and rigid rules for those who create these beautiful and realistic reverbs, but the truth is that, since the IR is essentially just a sound file, anyone can go out and record their own IRs and load them into a convolution reverb plugin. And if you’re in search of a new sound altogether, you can throw all the rules right out the window and basically hack the plugin, because any sound can replace an IR. The weirder the better.

Now we are in experimental territory and that elusive sound effect is out there somewhere. The more out-there sounds you try, the wider range of results you’ll get. I’ve come up with a few hints as to what kinds of sounds yield interesting results. Look for things with movement to them like pitch shift or volume modulation. You also want to stick to short sounds. Longer ones can bog down the processors and just generate muddied-up sounds … but of course disregard that advice if you are looking for muddy sounds. Really, anything could work: it’s all about trying new and different ideas.

There are a few practical things you should do in order to get the best results. First up, before you import a sound into your convolution reverb, you will want to prep the sound file a bit. I always bring the sound file into my DAW and edit out any silence at the head and tail. This is important as silence will not be understood by the plugin algorithm as silence. The computer will apply a bunch of complicated math to the nothingness and create zero effect. No point in wasting CPU power like this, so top-and-tail the file extremely tightly. Apply super-short fades to the file ends to eliminate any clicks. Next, you want to make the sound as loud as possible without clipping. (Actually you can get some crazy sounds from IRs that are maxed to clipping, but normally that’s not what you’re going for.) You want to have as much data in the file as possible – because using up all the headroom available will give the algorithm more information to work with. Quiet sounds just don’t create as much of an effect. The easiest way to do this is to normalize each file. I usually normalize to -.05 dB. (Normalize each file individually rather than in a batch, otherwise you will be normalizing everything relative to the loudest of all the sounds highlighted, instead of each sound on its own.)

Once you have the sounds prepped you can import the sounds into the convolution reverb and trick the plugin into believing the sound is an IR. I won’t go into the specifics of this here, as each make of plugin will do this in a different way, with different levels of complexity, but for some it’s as simple as clicking ‘import IR’ in the plugin’s library interface.  Once you have a bunch of sounds imported as IRs it’s time to experiment and play around. Here it’s important to consider both sides of the equation… meaning the sound you use as an IR is as important as the sound on which you are applying the effect. Using a rattling chain as an IR can create a great effect on a drum loop, but it just makes a sloppy mess out of a repetitive sci-fi alarm. So it’s a question of fiddling about with the combination of the IRs you create and the sounds you apply them to.

Inspiration hides in unexpected places. I found a telescoping back scratcher in my Christmas stocking and I quickly realized that when it was fully extended and whipped around, it made a great swish sound cutting through the air. So I set up a mic in the recording booth and recorded swishes until the little back scratcher broke in half. Not what Santa had in mind, but I was happy with the results. The following sounds are a few of those swishes as they were originally recorded, followed by the exact same swishes with the ‘reverb’ from a variety of unconventional IR’s.

Take a listen:

To be honest, some of those were not much to write home about but a bunch of them will be entering my effects library for sure.

Where this trick has been particularly useful to me is in the design of slow motion or time lapse sequences. Going back to my original dilemma, where I’ve hit the wall searching for the right original sound, I’ve deployed some abstract thinking and taken a sound that relates to what is on screen and used that as an impulse response. What I’ve ended up with is a sound design element that works particularly well in sequences with skewed screen time. Using this same logic, I’ve sampled animal sounds or human screams as IRs applied to machines or vehicles, creating some original anthropomorphic effects.

Using sound files as IRs is a bit like spinning a roulette wheel as you never know which pairing of IR and source sound will work well to create that perfect new sound you’re looking for. You simply have to spin the wheel and see what you get. With practice, you’ll start getting a bead on things that will work best, but this is a technique that has been most productive for me when I didn’t know what I was looking for in the first place.

Triple Dose of Blog Posts

First up Rene Cornado has this great post about Quad Miking Dual MS:

So instead of running more controlled experiments with regards to my quad setup, I ended up with a quick and dirty dual MS rig out in the field this past week.

The rig consisted of a pair of schoeps CMC6 bodies with the Fig 8 capsule and the hypercardiod capsule making up the front portion, and a Line Audio CM3 rigged up for the rear M all inside of a big rycote blimp.  The schoeps mics went straight into a 744t 1-2, and the CM3 went through a sound devices M1 and into the 744t channel 3.

Next from Timothy Muirhead is this fantastic article on recording hot air balloons:

I am offering up free downloads featuring 20 different bursts of flames from the hot air balloon burners for readers to use in their own projects.  Except for the start and end, each burst is essentially filtered white noise while the flames are roaring.  Yet the starts and stops can be really useful, if used smartly.  With some creative editing and some judicious use of plugin processing I have been able to use these sounds quite a bit in recent projects.  The bursts were handy as a sweetner element in scene with a large building going up in flames, they allowed me to give the fire some added character.  It also was used in weapon sound design for an anime series I worked on.

And finally from Michael Raphael a quick write up involving a Cambridge Typewriter:

By the time the day was done we had spent over 6 hours in Cambridge Typewriter and we recorded eight typewriters. We managed to record a Royal 10, Woodstock Standard, Olivetti Lettera 22, Corona Sterling, Smith Corona Classic 12, Royal Companion, and an IBM Selectric. It was a ridiculously humid and after that day Tom officially has earned the status of mensch. Tom dutifully typed a variety sequences for us and imparted tons of useful information about each machine.
