Imagine being able to capture and store the sound of an acoustic space, like a local church, cathedral, or even your favourite recording studio. Now imagine being able to use that stored file, in a convolution reverb plugin to make any audio sound like it was being played in that space. Now imagine being able to capture the sound of that acoustic space right on your iPhone.
Introducing iResponse for the iPhone. The first impulse response iPhone application intended to generate impulse response files for use within reverb plug-ins. This application is able to record and generate impulse responses for any acoustic space. You can use both impulse-source excitation methods (such as a balloon popping, or a starter pistol firing) or you can record a steady-state excitation signal through a loudspeaker. The excitation signals to be played back through the loudspeaker consist of swept-sine tones of varying lengths. The process is simple, point your iPhones built in microphone at the sound source within a given environment, select the length excitation signal you are using, and hit record. Once the recording has stopped automatically, its a ‘one-button’ process to perform the deconvolution processing required to generate the impulse response.
