> > Acoustic Mapping Project -- informal update
>>
>> The list of people interested in multi-speaker work continues to
>> grow, and the specific interests expand. Below is a brief summary of
>> ideas.
>>
>>
>> Ideas etc
>>
>> (1) Acoustic Mapping Project
>> A major problem with multi-speaker presentation of works created in
>> studio is that they may sound considerably different in a larger
>> space. An underlying them of this project is to be able to move work
>> from one (kind of) space to another space and get 'predictable'
>> results. This grew out of my own experience of having to prepare two
>> mixes of an 'ea' part of a mixed piece when it went from a dry room
>> into a concert hall.
>>
>> This is closely related to the automated sound projection of sources.
>>
>>
>> (2) Point source speakers
>> A second objective is to study using speakers as 'point source' sound
>> projection objects, that is, not to have 'diffusion' of the sound by
>> spreading the source over a number of speakers (the use of a 'matrix'
>> model of the space), but rather to think of movement in terms of
>> 'trajectory' (being able to go from speaker 1 to 4 without passing
>> through 2 and 3).
>>
>>
>> (3) Multi-speaker installations
>> The installation of many point-source speakers in a space where no
>> panning is expected. One version of this is the Butterfly
>> Installation Instrument employing 10 speakers and 5 CD players.
>> Details later.
>>
>>
>> (4) Non-conventional use or design of speakers
>> Speakers put in unusual locations, or with unusual designs --
>> spherical speakers which radiate into 270+ degrees etc. There has
>> been interest expressed in physical interaction (dancers, controllers
>> etc), and this may be able to be part of the first conference in 2005.
>>
>>
>> Context
>>
>> This is the start of a proposed three-year journey. In September 2004
>> there will be a 2 - 3 day symposium with concerts at Concordia
>> University in Montreal (Canada) - Sept 22-24/5. There will be
>> discussion panels on sound projection and multi-speaker set-ups.
>>
>> There will be 2 (or more) concerts of works composed to eight-channel
>> systems, and the Oscar Peterson Concert Hall will have
>> double-diamond, circle and shoebox configurations available.
>>
>> There will be one or more multi-speaker installations, including the
>> Butterfly.
>>
>> Given the availability of appropriate facilities, we may be able to
>> have presentation on the rapidly evolving field of "mastering" for ea
>> works.
>>
>>
>>
>> This will be a semi-formal event, and you are (all) invited to submit
>> work(s) to be presented. I have received about 35 - 40 minutes of
>> pieces already and expect many more before the end of August.
>>
>>
>> This preliminary symposium will also have a plenary session for the
>> first 'conference' in September 2005, and a degree of formalization
> > of this 'core' (research) group.
> >
> > It reached 27 degrees in Montreal 2 days ago, which was the first day
> > above about 22 degrees since the middle of October.

There is an informal list of interested people for this project. If
you wish to be added to the list, please contact me privately.
