PART 10: EQUIPMENT USED

CREATING AND ANALYSING THE AUDIO SIGNAL

• 60sec chirp signal generated using Audacity 2.0.5 (Generate/chirp)
• Cavity response recorded using Audacity 2.0.5
• Frequency spectrum of response produced by Audacity Fast Fourier Transform (Analyse/Plot spectrum)

INJECTING CHIRP SIGNAL INTO CAVITY

• Chirp signal played from Classic iPod connected by audio cable to Digitech stereo 18W rms amplifier
• CW2190 4” shielded woofer (70Hz-7kHz response) speaker injects signal into cavity

RECORDING CAVITY RESPONSE

• Cavity response was recorded by Samson Meteor digital condenser microphone
