Orquesta del Caos opens a call for electro-acoustic works on the occasion of «Zeppelin Festival 2018 - of magnetophones and computers », to be held from October 17th to 20th, 2018 at Centre de Cultura Contemporània and Hangar (Barcelona, Spain).

1. General conditions of participation

1.1. Any person or group of people can participate without limit of age, nationality or place of residence.
1.2. The participation of each person or group will be anonymous, the organization will only know the authorship of the work after its selection.
1.3. There is no restriction on the number of works proposed by author or by collective.
1.4. The works may have been premiered.
1.5. The works can have any duration, although the organization reserves the right to suggest to the authors only a fragment of the same, to be presented in concert.
1.6. Works must be able to be adapted to the loudspeaker device that Orquesta del Caos has at Teatre del Centre de Cultura Contemporània de Barcelona, ​​which can be downloaded from here.
1.7. The works and the associated documentation must be sent to the organization before the end of Sunday, October 7th, 2018, CET. 

2. Categoríes

2.1. A category: AKOUSMA

Works fixed on support, designed for speakers, which do not require the participation of instrumentalists. Both stereo and multichannel works (up to 24 channels) are supported. 

2.2. B category: AUDIO+VIDEO

Works fixed on support, designed for speakers, which do not require the participation of instrumentalists, synchronized with visual video support designed for cinematographic screen. Exclusively stereophonic works are admitted.

2.3. C category: ALGORITHMS IN REAL TIME

Works generated during the execution time by computational implementation of some algorithmic process.

3. Admissible formats

3.1. A category: AKOUSMA

The stereophonic works must be presented in a file with two interlaced channels, at 48 kHz and 24 bits, without perceptual compression, WAV or AIFF types (with .wav, .aiff, or .aif extension).

Multi-channel works can have up to 24 channels, each one associated to one loudspeaker of our diffusion system following this implementation. They must be presented in as many monophonic files as channels contain the work, each of which must be 48 kHz and 24 bits, without perceptual compression, WAV or AIFF types (with .wav, .aiff, or .aif extension). All these mono files must be synchronized with each other and have the same duration, so the piece implies the beginning of the simultaneous reproduction of all the files.

In the case of presenting a multichannel piece it is essential to attach, in addition, a stereophonic reduction with two interlaced channels, at 48 kHz and 24 bits, WAV or AIFF types (with .wav, .aiff, or .aif extension).

3.2. B category: AUDIO+VIDEO

Works with visual content must be presented in a .mov file, h264 and HD full resolution 1920 × 1080, with the sound embedded in the same file at 48 kHz and 24 bits.

3.3. Categoría C: ALGORITHMS IN REAL TIME

Works in real-time should be delivered with an open source software application with all the needed data files (sound, text, image, plugins, etc.) to work properly.

Editable applications or executable documents are accepted in Max/Msp (Cycling74), Pure Data, Supercollider or any other programming environment that may be freely downloaded from the web and executed on MacOS 10.9.X or higher.

With regard to executable files, which facilitate the execution procedure of works, without having to install any other piece of software, they should run in MacOs 10.9.X or higher, and because we are asking for open source creations, they will always be accompanied by the corresponding source code
The piece of software, regardless of the environment, must independently manage the way audio information reaches the speakers. 

4. Documentation to attach

4.1. For each work submitted, in any of the previous formats, a data.pdf file must be attached, which can be downloaded here.
4.2. Once downloaded, you must complete the document and save it.
 

5. Submission of the works and documentation

5.1. In order to guarantee anonymity, the corresponding author or collective will have to choose a nickname or pseudonym to identify each shipment.
5.2. All audio files, including stereo reduction if necessary, files for real-time performance, and the data.pdf must be named by this nickname. When the work requires different files, these will have to be called differently according to the author (for example using the channel number to which the file corresponds), but the file names never should have a reference to author's name or to the title of the piece.
5.3. All audio files, including stereo reduction if necessary, and files for real-time performance will be compressed in the same .zip file, which will take the name of the chosen nickname. The .pdf file with information about author and piece must not be included in the compressed .zip file.
5.4. The compressed .zip file, as well as the corresponding .pdf file, will be uploaded separately to the same cloud folder through a platform that grants permanent links (Dropbox, Google Drive, OneDrive, Mega, etc).
5.5. To send the link (URL) to the organization to the folder in the cloud with .zip and the .pdf, you must fill out through the alias this online form. It’s not possible to propose several pieces in the same form; you have to fill it as many times as pieces you want to propose.

6. Public presentations of works

6.1. All works received can be heard in a stereo, using headphones, on October 19 and 20, 2018 at the hall of the Theater of the Centre de Cultura Contemporània de Barcelona (CCCB).
6.2. In addition, the organization will make a selection of the works received to be played in concert on October 20, 2018 at the Theater of the CCCB through the system of speakers of the Orquesta del Caos.
