Question 3: Which pioneer is credited with inventing multitrack recording?
- Thomas Edison
- Les Paul (Correct answer)

Question 5: What is a 'compressor' used for in audio editing?
- Boosting high frequencies
- Reducing the dynamic range of audio (Correct answer)
- Adding reverb to a signal
- Converting analog to digital
Correct answer: Reducing the dynamic range of audio
A compressor reduces the dynamic range by attenuating loud signals, making the overall volume more consistent.
Question 6: Which audio editing software is developed by Apple and widely used on Mac for music production?
- Ableton Live
- Pro Tools
- Logic Pro (Correct answer)
- Audacity
Correct answer: Logic Pro
Logic Pro is Apple's professional DAW, exclusively available on Mac and widely used for music production.

- Cutting a section of a track
- Distortion caused by a signal exceeding maximum amplitude (Correct answer)
- Applying a fade-out effect
- Syncing audio to video
Correct answer: Distortion caused by a signal exceeding maximum amplitude
Clipping occurs when an audio signal's amplitude exceeds the maximum level a system can handle, causing harsh distortion.
