Question 1

What sample rate is the standard for CD-quality audio?

Accepted Answer

44.1 kHz

Answer

CD audio is standardized at 44.1 kHz, while 48 kHz is more common in video work.

Question 2

Increasing the buffer size in your audio interface settings will generally do what?

Accepted Answer

Increase latency but reduce CPU load

Answer

Larger buffers give the CPU more time to process, lowering load but raising latency.

Question 3

Why are balanced cables preferred for long audio runs?

Accepted Answer

They reject electromagnetic interference and hum

Answer

Balanced connections use differential signaling to cancel out noise picked up along the cable.

Question 4

What is 'bit depth' responsible for in digital audio?

Accepted Answer

The dynamic range and noise floor

Answer

Higher bit depth (e.g., 24-bit) increases dynamic range and lowers the noise floor.

Question 5

A guitar plugged directly into a line-level input often sounds thin because the input lacks what?

Accepted Answer

High-impedance (Hi-Z/instrument) matching

Answer

Passive guitar pickups need a high-impedance DI/instrument input to be loaded correctly.
