A new innovative iPhone application called Impulse Response has been created by Sam Harman, and enables the user to record the acoustic characteristics of a room or location. This acoustic data can then be transferred to a computer and used to create audio using the room’s acoustic signatures, making the track sound as if it had been played and recorded within that particular room or environment.
For example, you could go to the Albert Hall and record its acoustic characteristics using the Impulse Response app, then add this data to music, allowing it to sound as though it was played and recorded at the Albert Hall.
How Impulse Response Works
The Impulse Response app works by capturing the unique acoustic signature of any given space. This is achieved by emitting a sound, such as a sine wave sweep or a burst of noise, and then recording how that sound behaves in the environment. The app then processes this recording to create an impulse response file, which can be used in digital audio workstations (DAWs) to apply the captured acoustic characteristics to any audio track. This means that musicians and audio engineers can simulate the acoustics of famous venues or unique spaces without physically being there.
Sam Harman, who has already launched the iPhone app Twinthesiser, which transforms tweets into sound, will be unveiling his newest creation at the 2011 Bournemouth University event. The technology behind Impulse Response is not entirely new, as impulse response recording has been a staple in professional audio engineering for years. However, what sets this app apart is its accessibility and convenience. Traditionally, capturing an impulse response required a significant amount of specialized equipment, including high-quality microphones, speakers, and recording devices. Impulse Response simplifies this process, making it possible for anyone with an iPhone to capture and utilize acoustic data.
Potential Applications and Future Developments
The potential applications for Impulse Response are vast. Musicians can use it to add unique acoustic textures to their recordings, while sound designers can employ it to create more immersive audio environments for films, video games, and virtual reality experiences. For example, a game developer could use the app to capture the acoustics of a medieval castle and then apply those characteristics to the in-game audio, enhancing the player’s sense of immersion.
Moreover, educators and researchers in the field of acoustics could use the app as a teaching tool or for conducting field studies. By making impulse response recording more accessible, the app could also inspire a new generation of audio enthusiasts to explore the science of sound.
Unfortunately, no information on pricing or worldwide availability has been released as yet for this interesting application, but as soon as it becomes available, we will let you know. Given the innovative nature of the app and its potential impact on various fields, it is likely to generate significant interest upon its release.
In conclusion, Impulse Response represents a significant step forward in making advanced audio recording techniques accessible to a broader audience. By leveraging the power of modern smartphones, Sam Harman has created a tool that democratizes the process of capturing and utilizing acoustic data, opening up new creative possibilities for musicians, sound designers, and researchers alike.
