Contribute to a class discussion about the following (if you miss the discussion, create a post that thoroughly discusses these topics):
- ground loops (hum) and how to avoid them
- the difference between balanced and unbalanced cables
- loudness (dB)
- how a spectrogram (frequency domain) is different than a waveform (time domain)?
- microphone types (dynamic, condenser, contact) and polar patterns (omni, figure eight, cardioid, etc.)
- what a preamp does and how to avoid clipping (distortion)
