When recording, I meticulously recorded audio samples of the crotales, an instrument with 25 individual pitches. To turn up the ambient microphones further would capture the unwanted noise pollution.
They only account for about 10% of the final mix because, unfortunately, there was a piece of machinery built into the PAC that was malfunctioning and making a consistent squeaking noise. The four AKG 414s were placed around the room to capture the natural ambience of the room.
