THE DECIBEL SCOREPLAYER AS A PORTABLE MEDIUM FOR SPATIAL PERFORMANCE

6/9/2020

1 Comment

 
Although the decibel score player was developed as a vehicle for the synchronous presentation of scores for performers, the audiofile capability opens the potential to use the app in the presentation of audio only and other synchronisation dependant audio activities. In the scoreplayer, formatted scores (.dsz. files) can be networked if they have the same file name and are of the same format (for example “scrolling”, “slideshow” etc), however the audiofileembedded in any instance of a .dszneed not have the same file name.

Therefore the number of channels of synchronisable audio available to a composer is only limited to the number of iPads in the network. The ability to pair with Bluetooth speakers provides an extremely portable option for multichannel audio in site specific performances. This facility has been used to perform a range of multichannel works.
Picture
In recent performances by the new music ensemble GreyWing, the scoreplayer has been used in this fashion to perform works by in site-specific and small-room concert locations and also as a source for multiple click-tracks.
Picture
In the work Njookenbooro, each iPad was connected via bluetoothto a speaker (red rectangles) allowing for independent spatialisation of 11 unique stereo channels of audio. Performers (blue circles) read by thescoreby  screenlightfrom the iPads. They were synchronised across an ad hoc WiFi network that was broadcast from a laptop. Solar lights were used to mark the pathway to the performance for the audience.
The facility has also been used to deliver (via headphone), synchronous and independent click-tracks to avoid the necessity for a multi-channel audio interface and headphone amplifier.

Sanctuary is an example of an "independent" click-track work - this visualisation shows the accelerating and decelerating impulses in four separate audio channels.
The timer clock display on the Scoreplayer has also been used to synchronise parts in works with traditional and timepoint style scores.
Picture
Peter Ablinger's Book of Returns is a collection of 30 extraordinarily contrasting 40 second modules. The modules include: solo-pieces, solo-electronics, a cassette player, a single note or a scale, a performative situation,  experiments with microphones, field recordings, picture projection, and, also what Ablinger describes as “ensemble situations”.
Picture
Ablinger says it is “always the connection between modules, the edge, is the crucial part: the perfect cut”. ​The facility to coordinate multiple channels of audio on iPads via WiFi was used to precisely synchronise the unfolding of each module and its contrasting performance practice.
