no mixer input sound design Asbjoern Andersen


For his latest SFX libraries, Stuart Keenan from Glitchedtones explored the No-Input Mixer sound design technique. And in this special A Sound Effect guide, he shares how you can start using this creative approach to creating new – and surprising – sounds.

He’s also generously giving away 40 premium recordings made with the No-Input Mixer technique, for free! Here’s Stuart Keenan with more on all this:

The No-Input Mixer technique turns any regular mixer into an instrument which generates sound by connecting the output of a mixer into one of its inputs, resulting in a feedback loop which can be played and controlled using the mixer’s knobs, faders and routing options.

Most-famously used by pioneering Japanese noise musician Toshimaru Nakamura and aptly described by Canadian musician Christian Carrière as ‘the sound of the circuits inside the mixer singing’, the No-Input Mixer has a wealth of both beautiful and anarchic audio waiting to be uncovered and is a useful, versatile instrument to add to the sound designer’s arsenal of sound generating techniques.

By introducing the instrument to the creative process, the sound designer is opened up to a multitude of unique audio possibilities. Unsettling soundscapes suited to science fiction, dystopian and horror projects, impacts, interference, broken transmissions, drones, malfunctioning machinery, future technology sounds and glitch elements are just a few of the fruits of the No-Input Mixer.

A plethora of twisted tones await anyone willing to unearth the sonic treasures of the signal gone ‘wrong’

While a single output into an input brings instant results, it’s when multiple outputs and inputs are connected that the fun really begins. When coupled with guitar effects units or anything else which will affect the signal, a plethora of twisted tones await anyone willing to unearth the sonic treasures of the signal gone ‘wrong’.


An example of sounds created with the no-input mixer technique

Please note that caution should be applied when creating feedback loops as there is some potential to damage equipment. We are, after all, connecting things ‘incorrectly’. Also, things can get loud, very loud. Having said that, I haven’t managed to break anything just yet and have recorded numerous sessions using a No-input Mixer. It’s best to get used to using your master volume as a panic control if things get a little out of hand.

10 No-Input Mixer Tips and Tricks

1: When starting out with the No-Input Mixer, it is perhaps best to not use headphones in case of any unpleasant surprises. With speakers, start off at a low volume until you are comfortable with how it all works. However, a limiter can always be used to reduce the risk of any unwanted audio nightmarescapes!

2: Keep things simple to begin with. A single channel feedback loop with no effects can produce plenty of great source material to work with and is the simplest way to get acquainted with the mixer being used as an instrument.

3: Use very short movements when tweaking your mixer controls, the smallest increment may produce a fantastic sound which could be missed if you are a little too quick on the knob or fader.

4: It is a good idea to have an EQ in the signal path as your mixer’s EQ controls will no longer be operating in their usual way due to the feedback loop. Tweaking the EQ as you go can help you sculpt a huge range of sounds from a raw feedback loop.

5: If you come across a sustaining sound that you like, let it run for a while without changing any of the mixer controls. The feedback will sometimes just stop by itself, but can often evolve into some really nice (or nasty) variations of the initial sound.

6: For a variety of drones, consider using an octaver, or simply pitch down an octave or two with software afterwards. Adding distortion will create harsher drones, which can easily be toned down and shaped with some filtering and EQ.

7: Science Fiction effects and atmospheres come easy with the No-Input Mixer, particularly, when delay units are included in the signal path. Try using a high feedback setting on the delay and experiment with the device’s settings, manually tweaking the delay time often brings a decent array of sounds, too. It’s also worth noting that when using a stereo delay, a feedback loop within a feedback loop can be created by connecting one of the delay’s outputs to its input.

8: When using battery powered guitar effects pedals, don’t worry if batteries are running low as this adds sonic artefacts which won’t be there when the power is at full, which is a nice little bonus!

9: Record everything! Many tones can be missed if record is not enabled while experimenting, so it’s best to get in the practise of capturing everything the instrument outputs from the very beginning, as it can be difficult to reproduce a sound exactly.

10: Finally, have fun, experiment, improvise and look at the No-Input Mixer as a unique sound generating tool you can delve into whenever you want a break from the more traditional sound design techniques. Also, playing with feedback and noise is just incredibly satisfying!

  • AUTOMATED BIRD NOISE REMOVAL

    DEBIRD automatically recognizes bird noises in your recordings and removes them with surgical precision.

    THE PROBLEM
    Meet the involuntary #1 enemy of recordists and editors alike: Birds.

    While their lively and delightful song is a true asset in nature ambiences, it ruins just about everything else.

    As a result, countless hours are spent on the rather tedious task of cleaning recordings before one can get back to the fun part and focus on the creative process.

    Meet DEBIRD – your simple but powerful tool that utilizes Deep Learning to do all the cleaning work for you.

    Sit back and relax while DEBIRD effortlessly extracts all the unwanted chatter from your audio file within seconds!

    HOW TO USE DEBIRD?

    1. Drag any sound into DEBIRD. It is analyzed automatically.

    2. Hit Play. Enjoy your de-birded recording! You can see the removed bird sounds in the lower spectrum display.

    3. Simply export the cleaned sound.

    THAT’S IT?
    Yes! It is really that simple. You need some more features? You can also do the following:

    Would you like to keep certain sounds that would otherwise be removed? No problem! Grab a boundary box or brush and show DEBIRD what to keep.

    Solo and export the extracted bird sounds if needed. DEBIRD can be used in the exact opposite way it was designed for.

    TIMESAVER
    DEBIRD turns hours of work into seconds.

    FAST PROCESSING
    No matter how fast you remove bird sounds, DEBIRD is faster.

    CUT THE SLACK
    No more need to plan recording sessions at night or use invasive methods such as scaring off birds.

    SMART
    DEBIRD‘s Machine Learning capabilities help the tool to improve over time.

    HELP US TO IMPROVE DEBIRD
    DEBIRD works with a neural network that further improves the more input it gets. We will continuously feed the deep learning algorithm with recordings of birds to improve the results and to better handle edge-cases.

    WHAT YOU CAN DO
    You have a file and DEBIRD struggles to properly remove the bird sounds? Contact us via debird@boomlibrary.com and send us your audio file. We will include it into the machine learning routine and DEBIRD will handle such cases better over time.
