声音转换工具--螺旋楼梯-SPIRALALALA - singing architecture

斯泽钦爱乐乐团的标志性螺旋楼梯被重新想象成一种声音转换工具。
在MDF节期间，我们将SZZECIN爱乐乐团的标志性螺旋楼梯改为35m长/15m高空间语音转换仪。邀请观众们对不同的空间声音效果进行实验，这些声音效果与沿着35m长的轨道上的球的运动同步。互动首先将球插入麦克风。然后录制开始，录制的声音停止后，球被释放，沿跑道向下滑动。由于定制的带有红外传感器和无线电模块的闸门，用于录制的声音转换与当前的速度和球的位置同步。由于传感器和微控制器测量球通过闸门的速度，也创造了球后的光轨迹。由于我们使用了五个扬声器——每层一个，我们也能够实现空间化的声音创造了声音“坠落”的错觉。作为一个最后的触摸，我们还使用了简单的投影映射与球的运动同步，使整个事情更可见的人站在爱乐乐团大厅。最后，我们创造了一个有趣的、吸引观众的视听表演，它体现了我们的愿景，即将新媒体艺术实践与建筑结合起来，并通过数字技术将生活呼吸到静态形式。

The iconic spiral staircase of the Szczecin Philharmonic reimagined as a voice-transforming instrument. During MDF Festival we’ve changed the iconic spiral staircase of the Szczecin Philharmonic into 35m long / 15m high spatial voice-transforming instrument. The audience has been invited to experiment with various spatialised sound effects applied to their vocalisations that were synchronised with the movement of the balls falling along 35m long track. The interaction starts with insertion of the ball into the microphone. Then recording starts and after the recorded sound stops the ball is released to slide down along the track. Thanks to custom built gates with infrared sensors and radio modules the sound transformations applied to the recording were synchronised with the current speed and position of the ball. The light trail following the ball has also been created thanks to the sensors and microcontrollers measuring the speed of the ball passing the gates. Since we were using five speakers – one per floor, we were also able to achieve spatialisation of the sound creating the illusion of the sound “falling” with the ball. As a finishing touch we’ve also used simple projection mapping synchronised with the motion of the ball to make the whole thing more visible for the people standing in the lobby of the Philharmonic. In the end we’ve created a playful and engaging audience-driven audiovisual performance that exemplifies our vision for integrating new media art practice with architecture and breathing the life into static form thanks to digital technology.
