Thoughts on ‘Ways of Hearing’ by Damon Kurowski

The podcast series Ways of Hearing explores shaping of our perceptions of the sound and recording in era of analog following by the digital era and switching in between them. The first episode of the podcast talks about differences of how our perception has changed from the point of view of the time.

After listening to the podcast I realised few differences comparing both eras. Analog time feels more present (‘real time’ recording), digital time provides certain realm of timelessness (easier possibility of endless back and forth editing). After listening to the podcast I realised that recording in the time of analog often required necessity of the musical skills and and way more precision in executing them. Recording must have been done precisely in order to safe material (recording tapes) and therefore money. Of course in the digital world the same skill is still appreciated but doesn’t seem to be so essential as on computers we can edit much easier than cutting tapes or re-recording the whole takes. In the end of the day it always breaks down to the preference and there are people who these days prefer to edit as well as to record the whole takes precisely. However, and that was another important point mentioned in the podcast, in analog era this wasn’t an option.

Coming back to analog-present versus digital-timeless. Digital technology also entered the music composition. Drum machines put music more onto the grid together with evolving but constant repetition. A lot of popular electronic music sort of endeavour to reach some sort of timelessness – being able to tap in at any moment possible. This extends into ways how we nowadays reproduce and stream the sound.

Of course both eras has pros and cons. Digital technology made sound and media in general more affordable and attainable to almost everyone, but according to Damon Kurowski, this came with the cost:

“We give up on the opportunity to experience time together – in the same instant – through our media.”

This extends also to the nowadays common way of communication via texting and social media. In analog time the conversation often had a start and the end and somehow more often encompassed the goal of its content. These we have an option to step out of the texting at any time possible and come back to it whenever later – but later the momentum of the conversation or the necessity of communication of of agent involved in the conversation with another one, might be long pass.

Connecting BNO055 sensor with Arduino and sending data to the computer via Bluetooth

The other week, I progressed with connecting to the Arduino Nano with BNO055 via Bluetooth module HC-05. As described in a previous post, BNO055 is an accelerometer, gyroscope and magnetometer in one device. I intend to implement BNO055 into the glove and use it to control the spatial panning. Basically sending the sound into particular spot in the certain direction by pointing out into that direction inside of the octaphonic ring.

I used the help of ChatGPT to generate the code for Arduino Nano, which will wirelessly send raw data of the position of three axes, x, y, and z, to the computer.

The video below shows that the Serial Monitor of Arduino IDE receives raw data in the form of numbers from three axes: x, y and z. The cable is used here only to power the Arduino. This will be, of course, replaced by the battery power.

The next stage will be creating a Max device so I can implement the x, y and z data and transcript them into MIDI, which will be possible to map to a Max For Life device called Surround Panner.

Creating a Calibration device for sensors in Max and implementing it into Ableton Live

In the previous post I have described the problem which I encountered , a flex sensor not entirely covering the whole MIDI scale from 0-127 and having an initial point somewhere in the middle of the scale. My idea is that the flex sensor will be carefully positioned on the fingers of the gloves as well as in the bent points of the suit (under the knee, in the crook of an arm, potentially on the other bending parts of the body). I want the flex sensor to control the entire MIDI scale from 0-127 and make it mappable to any parameter in the Ableton in cooperation with Arduino Max For Live device.

Non calibrated flex sensor mapped to a Dry/Wet parameter of the reverb via Arduino device from the Max For Live’s Connection Kit

In the video above, you can see that the initial point of the flex sensor is somewhere around 40% (approx. number 43 on the MIDI scale) in of the Dry/Wet parameter and reaches somewhere around 80% (approx. number 86 on the MIDI scale). I will set the same input values into the calibrator to demonstrate its function in the video below. This time I mapped the output to the decay of the reverb.

As you can see, once the parameter sent by the sensor reaches the threshold set on the MIDI input (number 42), it triggers the output mapped to the reverb’s decay. It controls its full scale until it reaches the top possible value of the sensor (number 86).

Calibrated flex sensor ‘attached’ on the elbow

This calibration device has the potential to calibrate any other sensors sending any unstable values and stabilising them into desired MIDI parameters. It can be, for example, used vice versa as well when the input MIDI information sends the full scale of 0-127 and the output has a particular threshold and limit.

The core of the device is a zMap object, which maps the input range of values to the output range, and map button patch. Schematics for the patch in Max is below.

The calibration device will eventually be extended to accommodate multiple parameters (for example, controlling five different flex sensors attached to the fingers of the hand) with map buttons added to its inputs.

‘A Quiet Place’ – Organising the sound

I have separated the sound design for the film into three main groups – foley, effects and atmospheres.

Foley was recorded on one microphone AKG C414. Unfortunately I encountered a lot of the background noise but I have removed it by using the plugin iZotope RX 7 Spectral De-noise. Atmospheric drones are layered from recordings of various electromagnetic waves, for example from the interior of Overground train and random by SOMA Ether and run through the reverb with a long decay and horns are a preset of the virtual instrument called Analog from Ableton Live 11.

You can see the arrangement of all tracks in Ableton Live into three groups below:

Most of the scenes from the clip take place inside of the building, possibly former grocery store. To create the sense of large empty store I have applied reverb of small size and with very short decay on all the foley:

For one of the atmospheres which were mimicking the sound of refrigerator I used slightly larger reverb to create some distinction in the perception of the space:

I was originally experimenting with creating the effect of sensing the physical movement, especially in the scenes with very fast tip toe running, by using the phaser and phase shift but desired effect didn’t work. What appeared to be working to achieve the similar effect was simply automation of hard panning following the direction of the runner from left to right.

Mixing was done in the composition studio at London College of Communication.

Thoughts on ‘The Walkman Effect’ by Shuhei Hosokawa

When the Walkman emerged in 1980, it started a revolution in how we consume music and other sonic media. There were, of course, appearances of negative and fearful opinions predicting that Walkman would make people psychotic and disconnected from the surrounding environment. There have always been fears and uncertainties attached to new inventions throughout history, not only from the media realm. For example, the printing press invented by Johannes Gutenberg in 1440 was, by certain groups, considered a threat to public morality because the sudden access and democratisation of wider knowledge provided by books to common people allegedly could cause chaos in what we are being taught. Indeed, at the time, it caused the acceleration in questioning of certain status quo, and the invention of the print press played a significant role in enabling Christian reformation in Europe in the 16th century. Nowadays, we encounter similar discussions regarding Virtual Reality headsets with fears of people becoming utterly detached from reality. Did the Walkman become comparatively influential politically? It may have become another expression or by-product of individualism.

When we discussed in class how the invention of portable audio devices (we can extend Walkman followed by Discman, MP3 players, iPods, and smartphones these days) is influencing our interactions with the environment and our reasons for using them, people were describing similar things. The Walkman became a predominantly urban audio device, and many people use it to conceal or shield themselves from the city environment’s surrounding chaos.

Portable audio devices also change our imagination induced by music (or other sonic art forms). Before, it would be exclusively tied to a place produced live at the gig or at home, reproduced by a record or a radio station. The Walkman suddenly opened the door to the ‘scoring of the life’ on a different level. New sceneries (from urban to natural ones) supported by our choice of favourite music suddenly provided new scales of imagination and possibly even inspiration.

It also changed the way we walk in the environment. I found myself extending my journeys on streets to wherever I was heading on many occasions so I could listen to my favourite music for longer. Occasionally, it became an unconscious ritual reminding me that ‘the journey is the goal’.

All this suggests what is written in the article about the Walkman providing certain autonomy (Hosokawa, 1984: 166). Having the possibility to opt in and out from whatever is happening around you is undoubtedly an advantage, but there are also negatives coming with all of this. I certainly haven’t encountered anybody losing their mind and getting psychotic attacks based on prolonged headphone-wearing. However, hearing damage from quite a young age is real – reducing sensitivity to specific frequency ranges contributes to developing severe and long-term tinnitus (both based on my own experience).

Recording Foley for the scene from the film ’A Quite Place’

Here is few photos and videos from the first foley recording session which happened on 11th November 2023. During the recording I have encountered several problems, which I more or less resolved. Firstly, th emain problem was that monitoring room wasn’t available so all the recording happened in the actual live room. I have used my favourite condenser microphone AKG C414 and sound-interface Focusrite 2i4.

Ropes used for recording of the dry grass and leaves
Recording of pill bottles and bottle of water
Recording of paper posters in the wind

The fan from the laptop was quite loud therefore I had to improvised with building a sound barrier as you can see below.

I have recorded foley for 2 minutes and 30 seconds. The second session is being planned for 13th November. Some of the clips contain quite harsh noise and I am not entirely sure when it comes from. I will either re-record them or will use noise reduction plug-in from Izotope.

Tom Fisher

Tom Fisher, aka Action Pyramyd, is making sample-based music based on tiny sounds from his field recordings. He considers field recording and composition as a mode of thinking and experiencing the world. His experimental audio recordings have a very ecological aspect to their work, often based on the recording of water plants. How does he record plants? Firstly, he listens to the environment and examines the scale and overlaps of sound types. Then, he uses a hydrophone to capture the sound of photosynthesis.

I found it interesting how Tom Fisher can contribute to biological and ecological research by applying sound arts. For example, the mapping of the acoustic diversity of various ponds. Collecting data with a hydrophone could show him a lot about life in the pond in a non-invasive way. You can see that night is sonically dominated by the activity of aquatic insects and early afternoon, just after the solar zenith by aquatic plants due to high amounts of energy received from the sun (this is when he could listen to actual photosynthesis happening in the plants).

Tom Fisher realised in relation to hydrophones that since our ears cannot function in the underwater realm to pick up the same frequencies of sound – so what are we looking to recreate? Even conventional microphones lack the capacity to depict the soundscape in the same manner as our human ears perceive it in the situation.  It is also all temporal, a construct; these moments aren’t happening simultaneously everywhere. He treats recorded material with sensitivity and reverence. He is recreating the ‘realistic’ illusion of an environment/sonic situation and acknowledging that editing and implementing his creative decisions are part of the process, but he is still trying to create an engaging narrative for the listener, raise awareness (about something undervalued like a for example pond) and break down hierarchies.
