This internet available demonstration web application<\/a> (webapp) allows selection of a sample audio recording, an impulse, plays through convolution reverb with Wet\/Dry, Pitch Shift and Speed control – a work in progress. The resulting sound can be heard on the user device. On the backend web server, Open Sound Control<\/a> (OSC) messages are sent so that a visitor to a gallery can use their smart phone to interact with sound sculptures as part of an electro acoustic sound art installation. This is implement primarily in Javascript<\/a> JS and HTML<\/a>.<\/p>\n\n\n\n

Click for defintion of convolution reverb<\/strong> and “impulse<\/strong>” (IR)<\/summary>\n

An Impulse Response (IR)<\/strong> is\u00a0a WAV file that captures the sonic “snapshot” of a speaker cabinet, microphone, or acoustic space<\/mark>. Used in audio processing, it acts as a high-resolution EQ and character filter, allowing users to emulate specific resonant objects or spaces.<\/p>\n\n\n\n

Convolution reverb<\/strong> is\u00a0a sample-based software based effect processor or pluging that uses an\u00a0Impulse Response<\/a>\u00a0(IR)\u2014a recording of a real space or hardware\u2014to accurately simulate natural reverberation<\/mark>. Unlike algorithmic reverb, it captures the authentic sonic footprint of environments like halls, cathedrals, or vintage plates. <\/p>\n<\/details>\n\n\n\n

The Active ID for instance might be used to select which loudspeaker or sonic object to send a signal to. This works from most any modern browser & device (iPad, iPhone, Laptop, Destkop, Android, Raspberry Pi).<\/p>\n\n\n\n
