Audio Test Kitchen was founded by Alex Oana and Ian Hlatky. It is the world’s first online virtual microphone showroom. It offers unbiased microphone comparison across hundreds of different large condenser microphones. The good thing about it is free to use. It also allows users to audition each mic directly through their headphones or speakers.
Audio Test Kitchen relies on DPA’s 4041 large-diaphragm mics, 4011 cardioid mic and 4006 omnidirectional mics as reference points. The company captures a vocal performance in an anechoic chamber with the DPA mics and replay the audio through a specially tuned loudspeaker that serves as a surrogate for the human voice.
