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
