Ritornell's business cards are inspired by the project's live show. The improvised concerts evoke a lively atmosphere by the combination of filigree electronics with playful timbres of diverse acoustic instruments and utensils such as egg whisks, toilet brushes, chopsticks or sewing needles. As an integral part of their set list, Ritornell invites the audience to bring along their private musicboxes. Arranged in a big circle, the players' speed of turning levers is conducted: the results are as shimmering as you would expect.

Katharina Hölzl designed very special business cards to recreate this playful sonic universe. With the aid of laser assisted milling, nine micro compositions consisting of circles, triangles and Ritornell's contact information were applied onto a long musicbox paper stripe. Before handing out the cards to interested adressees, each individual subdivision is played back via an especially designed musical box – thus providing every business card receiver with a tailor made musical experience.

Vinyl Rally: video game /sound installation by Justin Yeldham

via ./mediateletipos)))



Lucas Abela –a quien algunos conoceréis como Justice Yeldham– ha creado esta instalación interactiva llamada Vinyl Rally que combina arte sonoro, escultura, vídeo y 'deporte' en un videjuego que consiste en mover coches a control remoto por una pista construida de discos de vinilo. Los coches llevan incorporadas unas pequeñas cámaras y transmiten tanto vídeo como sonido, el sonido es generado directamente por unas agujas colocadas en los coches que pasan por encima de la superficie de los vinilos.

El resultado es similar a un videojuego de coches típico, pero el jugador conduce directamente desde el punto de vista del coche físico, y este va creando diferentes efectos sonoros.

Info and tricks for contact mics




CONTACT MIC is a new library of sound design source material recorded by Tim Prebble and released by HISSandaROAR, including 1,556 sounds recorded at 192kHz/24-Bit using contact microphones.
Recording with contact microphones is fascinating territory to explore due to the unpredictable results; it encourages experimentation! Inspired by the incredible work of Alan Splet and Anne Krober on Dune (as described in this article) I bought a custom built Trance Audio Inducer contact mic and preamp back in 2001, and have been experimenting with it ever since. A couple of years later I added a pair of Barcus Berry Planar Wave contact mics and while these mics featured in Tortured Piano this library is something else again: it is literally the result of hundreds of hours of experimenting.
One aspect of contact mic recording that is fascinating for sound design is the lack of acoustic – there is no reverb due to the sounds being recording via direct vibration, not through the air. This feature alone makes for very malleable sounds, excellent as components and layers in complex, composite sounds or for when you need an abstract organic sound but where the actual source must remain concealed…
The library is available at Hiss and a Roar for $99. Also check this article at themusicofsound, where Tim talks about the release.

What inspired the library?
Back in the 2001 a friend gave me an old copy of American Cinematographer magazine from 1984 which had an interview with Alan Splet & Anne Krober about their work on the film Dune. One section described their use of the FRAP contact mic and it totally set off my imagination! [article link]

What model contact mics did you use?

After reading that article I went hunting for a FRAP only to discover they were no longer available. I pursued some DIY approaches but the results just were not that useable – it was obvious the frequency response was not full range. But then I found the Trance Audio Inducer, which came with a matched preamp. This was a revelation to me, especially with regards to the tonality of the sounds and the low frequency response. A year or so later I bought another contact mic for my double bass, but it didnt have the same sensitivity so I went back to Trance Audio to buy a second Inducer only to discover that model was no longer available either! Next I tried the Barcus Berry Planar Wave contact mic, which also came with its own matched preamp and I ended up buying two of them as they produced similar great results to the Trance Audio. The library is all new recordings, but its based on my experiences recording with these for the last ten years.



Are there any special techniques or advice for using contact mics that you can share?

Well, the first & most important aspect is the matched preamp. Like most sound editors I own many different recorders & preamps but it seemed the only contact mics I got great results from were the Trance Audio and the Barcus Berry when used with their own preamps. I learned this through experimenting but only recently discovered why that is. I'm sure the reasoning behind is very basic for anyone who has studied electronics but this article spells it out…

"The problem with piezo guitar pickups and contact mics is that they are not well matched to typical audio inputs. By their nature they can generate a lot of signal, but they cannot drive a 50 kilohm typical line input. The pickup needs to work into a much higher impedance, typically 1 megohm or so.

The reason why these devices often sound tinny is because the piezo sensor presents its signal through a series capacitance which is small, typically 15nF or less. When wired to a normal 50 kilohm line input this forms a 200Hz high-pass filter, which eliminates the bass.
If wired to a consumer plug-in-power microphone input of about 7 kilohms impedance, the result is a 1kHz high-pass filter. Hence the reputation for poor bass performance…."

So impedance matching is the key and explains why many DIY contact mics sound thin – people buy a cheap piezo element & plug it into a line or mic input. They get a signal & it is useable, but you don't have to be a rocket scientist to appreciate what a 200Hz High Pass Filter does to the sound.




What about props? Contact mics were traditionally created for musical instruments, what else do they respond well to?

Psychologically using a contact mic makes you look at the world in a different way. We are all so used to hearing and interpreting the world through air molecules and acoustic spaces. And an important part of being a sound recordist is being able to hopefully predict how sounds will react in a space. But using a contact mic makes you put your assumptions aside and experiment because the results can be counter-intuitive. Sometimes I've found a prop and thought: "THIS will sound AMAZING with a contact mic" and then hooked it up & been thoroughly underwhelmed. What seems resonant & complex through the air may well have a singular pitch & be far less interesting with a contact mic. But its when the reverse is true that things get exciting.

I'm sure I'll work out the pattern  at some stage, but in many ways the mystery is actually a pleasant side effect. Not knowing the outcome means when you do stumble across a beautifully resonant body, time slows down & you become completely absorbed into physically manipulating the sounds. I totally agree with Dave Farmer about not always wearing headphone when recording, with the one exception being when using contact mics. 

The exact placement can make a huge difference in the tonality of sounds, especially on hollow resonant bodies. Depending on what the object is made from there is also often a huge range in dynamics, which means setting levels can be tricky and requires constant monitoring. But it also fascinates me that some of the sounds recorded with a contact mic that you perceive as being big, loud, aggressive sounds were actually created through very subtle movements. The big blue water bottle in the video is a good example: hitting it hard with a mallet produced a harsh sound, but hitting it very gently with a soft bass drum mallet produced a sound that would excite your subwoofer!

With such diverse sounds, how did you go about categorising them?

About half way through recording the library I came to realise that a good way to think of the sounds is 'resonant body' versus 'activator'. Over the years I've slowly built up a collection of props that respond well to contact mic recording, many of which feature in the new library. But I've also slowly collected up a suitcase full of activators, so the files are named based on this approach. But I also spent time making sure every file in the library has a photo of the prop included so you get an actual image of how the sound was created when browsing in SoundMiner.



What are some of your favourite sounds form the library?

My favourites tend to be the unexpected new sounds I discovered while recording. One good example is the rubber recording. I had never thought of sticking contact mics to a balloon but I did and spent half an hour getting fairly familiar sounds from them and I didn't include those sounds in the library. But it got me thinking, what if I used a much bigger balloon and only partially filled it with air, so it is a large resonant body but with very low air pressure? I gave it a try & discovered some really expressive sounds which I can only describe as sounding like a whale with indigestion! The low frequencies are quite amazing, because the pitch variation was totally controllable and they sound unreal at half speed!

Like most sound effects editors I have a lot of metal recordings in my library but during these sessions I managed to record some metal sounds that I have simply never heard before. Due to how I was applying pressure the two metal elements produced almost rhythmic stutter effect!

Another funny sound I stumbled across reflects an aspect of why contact mic recordings can be so useable. Because the sounds are recorded through direct connection with the vibrating material, there is no room acoustic or reverberation. This means the sounds can be used as layers or components in composite sounds without the listener being able to identify the source, but it also has a less obvious benefit for recording. One example was when I was recording different scrapes & movements across a metal bowl. I was performing them with a knife and a drill grinder bit, but I was interested in more complex sounds & remembered I had my battery drill at the studio. Normally if I recorded anything that involved the drill, it would have the sound of the drill motor all over it. But if the contact mic is not attached to the drill it doesn't hear it at all! So I started putting different activators in the drill & trying them…

Sonidos extraños del cielo reportados en todo el mundo

From Trinityatierra


Ruidos parecidos a truenos, cuando no hay tormenta, silbidos, zumbidos que llegan del cielo, algunos realmente extraños, están siendo reportados en todo el mundo  y algunas veces precediendo a terremotos. El fenómeno ha sido observado por miles de personas en estadios de fútbol americano y algunas ciudades.

He podido encontrar vídeos que no parecen estar siendo manipulados (como ocurre siempre que hay algo extraño, por supuesto hay otros que sí lo están y donde sus autores se ríen de cualquiera que se acerque a verlos) en Ucrania, multitud de lugares de Estados Unidos, Chile, Suecia, Holanda, Bielorrusia, Brasil, Rusia, entre otros.

Los vídeos están grabados, en su mayoría entre Junio y Setiembre de 2011, así que esto es algo de total actualidad que no ha podido ser explicado por nadie hasta la fecha de modo satisfactorio. Los sonidos son ligeramente diferentes en algunos casos: algunos son similares a un tren, otros suenan más como un viejo submarino   abriéndose paso en el océano, otros se parecen más a zumbidos que llegan del cielo, como en el caso de Durham, UK, un caso que ha dado la vuelta al mundo porque todos sus vecinos han estado semanas escuchando zumbidos inexplicables que llegaban del cielo, caso reportado por The Telegraph.

El siguiente caso, por ejemplo, saltó a los medios de televisión nacional porque durante la celebración de un partido de beisbol se escucharon unos ruidos   inexplicables en el cielo, justo el mismo dia, 23 de agosto del 2011, cuando poco después tuvo lugar un terremoto en la costa este de los Estados Unidos.


Con diferencia, uno de los vídeos más impresionantes que me he encontrado, ha sido éste grabado en Ucrania. Las voces de fondo , una de ellas de un niño, comentan que los sonidos llegan del cielo y que no entienden qué ocurre. Se graba sin interrupción durante 11 minutos.

A Strange Border - Essay on Music and Sound, by Paul Davies

From Designing Sound

[Written by Paul Davies]

There is a strange and porous border in film sound and that is the one that exists between music and sound design, it is not a sealed and clearly defined boundary, but an open, shifting and nebulous one, easy to cross over back and forth, sometimes inadvertently and other times boldly and deliberately, by both the composer and the sound designer.

One might ask what is the difference between music and sound design? A flippant answer would be royalties. A better answer would be at times a great deal and at others not much at all. For the most part the roles of music and sound design are clearly defined, music in film continues the role of the “pit” orchestra from the days of silent cinema, commenting, narrating and guiding the audience emotionally through the action.

Sound design mostly exists within the world created on screen, but from time to time it steps out from this perhaps “functional” role and crosses over the borderline into music, and it is this area of overlap and blurring of distinction between the two that I find increasingly interesting. The films of David Lynch and the work of his sound designer Alan Splet are good examples of this ambiguity and were an early inspiration for me, their early film “Eraserhead” in particular.


Most sound designers have a musical background, which may be a formal one or perhaps, like me, their love of sound started in manipulating electronic instruments and discovering the wonders of the recording studio. The reason I call the supposed divide between music and sound design a strange border is because it is often an arbitrary one, for example an atmospheric drone can be created by a composer and it is a music cue, similar material created by a sound designer is a sound effect.

In the past I have contributed sound design elements to films that I felt had crossed that border from sound design into scoring, I’m thinking in particular of moments in the films Love Is the Devil and Chatroom. I used to have a rule for myself that I restricted what I did to utilising un-pitched sounds – pitch and rhythm being the province of the composer. However, I have recently crossed over this border and, I must hasten to add, did so by the invitation of the filmmakers themselves.

One such film was The American, another is the most recent Lynne Ramsay film We Need to Talk about Kevin. In The American I was asked by the picture editor Andrew Hulme to supply for certain sequences in the film, “compositions” formed from what might be termed atmospheric sound design elements, that he felt would be better able to convey the tension in those scenes then perhaps  “traditional” music cues would.
In Lynne’s film, because I had started work early in the film editing process, I supplied a few music/sound design pieces to Lynne and the picture editor Joe Bini to help them with the cut, a composer hadn’t been chosen at the time, and I also provided them with some further pieces from other composers and sound artists. About four of my cues found their way into the final mix and some others exist as underlying tonal elements. The score was written by Jonny Greenwood and my elements and his music seemed to combine in a unique and fortuitous way.

I’m not trying to set myself up as a film composer I don’t have the necessary skills and I have too much respect for the craft of people like Jonny Greenwood, Ryuichi Sakamoto, Adrian Johnson, Dickon Hinchliffe amongst the many composers I’ve worked with, but I think what skills I do have are suited to those occasions and those films that sometimes require sound/music elements that lie “in-between” the border of music and sound design. The “compositions” may contain little traditional musical material, but they somehow convey emotion and drama more than just a drone or atmosphere sound would do, perhaps they do this by shifting and transforming themselves through the scene, and if they do have a musical element it is a very simple one.

I realise that I can only speak for myself and my own experiences, but it’s interesting to note that one of Hans Zimmer’s collaborators Mel Wesson has for a long time provided similar elements on films such as “Inception”, “The Dark Knight”, “Michael Clayton” and many other films. Mel’s term for this is Ambient Music Design (and further information can be found at his website with the interesting caption on the main page “music is noise”). So I’m sure that I’m doing nothing new here, and I wonder how many others find themselves contributing “music” cues through sound design, whether that is acknowledged on the cue sheet or not.

In terms of technology, I love using the midi functionality of Nuendo, as well as having a liking for Mackie’s sequencer Tracktion, which features very impressive time stretch and pitch shifting capabilities, software instruments and effects from Native Instruments and Waves diamond bundle and GRM Tools for processing, I regret to say I haven’t plugged in my hardware synths and effects for some time, but keep on meaning to getting around to it.

For those who may be interested examples of music/sound design I’ve contributed to films and other bits and pieces can be found at SoundCloud

19th-century chant notation from Tibet

From Acousmata.com

“The MS belongs to the ‘Yang’ tradition, the most highly involved and regarded chant tradition in Tibetan music, and the only one to rely on a system of notation (Yang-Yig). The chant consists of smoothly effected rises and falls in intonation, which are represented by complex curved lines. The notation also frequently contains detailed instructions concerning in what spirit the music should be sung (e.g. flowing like a river, light like bird song) and the smallest modifications to be made to the voice in the utterance of a vowel. On the whole, Yang chants are sung at an extremely low pitch and at a lingering and subtly changing pace, allowing full expression of the chanted text. Such texts as these would have been used as a mnemonic device by the Master of Chant in a monastery in leading the monastery in the performance of a chant. This type of graphic notation of the melody line goes back to the 6th century. It records neither the rhythmic pattern nor duration of the notes.”
