Have you ever wondered what your library card sounds like?

Have you ever wondered what your library card sounds like?

I am working on a  a project with three libraries (Taunton, St. Thomas (Exeter) and Torquay) to create an engaging user experience using a Library Card Music Player. This project is funded by Arts Council England.  The idea for Library Card Music Player Project is to build three music-generating devices that will be installed into three different libraries.  Each device will produce and play a short melody created from a borrower’s library card and, every time a borrower uses the card, they will hear the same tune. 

Most libraries now have self-issue card machines and, in a similar way, users can scan their library card to produce a melody, almost like self-issuing their own tune. We hope that by engaging borrowers in such a unique way, this will attract more users to libraries.These devices will be bespoke for each library and workshops will be hosted to outline the possibilities, to discuss the technology used (Raspberry Pi computers), and to even create a unique device based on audio contributions of their own if desired.  By doing so, libraries will feel they have contributed in some way to the development of the work and will have a sense of ownership of the project.

The first workshop is at Taunton Library on Thursday 28th October followed by St. Thomas Library on Saturday 30th October. Details for the Torquay event to be announced.

Music Machine 4 for 8 players

When the installation piece Music Machine 4 for 8 players was cancelled due to Covid-19 in March I looked for an alternative way of presenting it. In common with many people I discovered Zoom and thought that this would be a good way of getting it done. I got a eight people to agree to do it, delivered the kit to them (maintaining social distancing), sent them a video that showed how to set it all up, did a couple of small trial runs and finally recorded the whole thing last week. 

In my trial sessions with Zoom I discovered that while it is great for video and splitting the screen into eight sections it is not so good for sound. I had to do a lot of audio editing to achieve a good result. Here is the final video:

Music Machine 2

I've had a new case made for Music Machine 2, usually I would use the laser cutter at FabLab Devon but this is currently closed. So I used RazorLab who provided a quick and efficient service with good communication as the job progressed.

Here are some pictures:

Here's a description of how it works:

Music Machine 2 consists of two elements.

The first is a repeated C major triad which provides the pulse for the machine. This pulse is played as quavers at 120 bpm.

The second element is the melody (also played as quavers) that is generated using the following rules:

1. The melody can only use notes from the C major scale.
2. Whilst it is possible to generate notes from any octave, the extreme high and low octaves can only play notes from the triad
(C, E or G). Any note from the scale can be played in the middle octaves.
3. The process is weighted in favour of making a middle octave selection.
4. There is a 50/50 chance that the note will be sustained rather than stopped when the next note sounds.

The machine will run indefinitely until stopped by the user.

This version uses an ultrasonic distance sensor and an Arduino.

And here's some video of it in action:

BBC Radio Devon

Just a quick post to let you know that I will be on BBC Radio Devon's Breakfast show tomorrow (Friday 29th May) at around 7.50 to talk about the soundmap project. You can listen here: https://www.bbc.co.uk/sounds/play/live:bbc_radio_devon (or on sounds afterwards).

Covid Soundmap

Over the last weekend I have completed the covid soundmap. I added the final two recordings to the map and have made a final version of Music Machine 45. The last two recordings were both made on Thursday 21st May in Exeter. The first was made in the morning when I walked into town and features the sound of some of the building work that has restarted on the bus station area. The second recording was made around lunchtime when I walked near County Hall. You can hear the sounds of children playing at the nearby St. Leonard's school. Both of these recordings provide a contrast to the earlier ones that featured bird song and little else; now the sound is dominated by human activity as the lockdown is eased.

The soundmap can be found here:

and all the audio recordings (including the first versions of Music Machine 45) can be found here:

This project was achieved with support from Kaleider.

Audio recordings, locations and process

Here is a little bit more information about the recordings and the process that is gone through to achieve the final audio collage.

I have made the recordings in locations that I have visited during this lockdown period either on foot or by bike. I intend to make a total of ten of these recordings.

The locations were not been chosen in advance; I take my recorder with me and make a recording when I find a suitable spot. However, I have found that my approach to making recordings has changed over the past few sessions. Initially I was happy to record at any location on my journey; I have found that as the project had progressed I actively seek locations that have more interest. So, for example, today I have made two recordings and have decided to use both as they have interesting elements within them.

The first recording I made today was close to an electricity sub station; you can hear the hum from that throughout the clip. The second recording uses my home-made hydrophone that I placed in a small ford in Thorverton. The sound changed quite noticeably half way through this recording as the microphone moved in the current.

The longest clip so far is the one that I made on Saturday in Starcross. I have kept the full recording as there are many interesting sounds on it. There is part of a conversation that two people had on opposite sides of the road, there is the sound of a train announcer, the train itself and a pelican crossing. Because many of the recordings have been dominated by bird song this one felt quite different.

The process that happens once I have all the recordings is as follows. The code for Music Machine 45, in common with most of the machines, is written in python. It is a digital Musique Concrète maker (or should that be mixer?) I can put in as many source recordings as I wish; the machine then decides how many smaller clips it is going to make from the originals. It then generates those smaller clips and decides how long they will be and from which section of the original. Once the clips are generated they are played back at various intervals, faded in and / or out, set to sound at a particular volume and location in the stereo field. As I say, this is very similar to Musique Concrète techniques and produces a work that is multi-layered and built from existing recordings.

Here's the link to the soundmap:
