Getting To Know Pro Tools

Question 1

What are some advantages of recording and editing in the digital realm? (3)

Answer 1

Non-destructive editing. Noise reduction. Flexibility.

Question 2

Describe the relationship between sample rate and frequency response in digital audio.

Answer 2

The sample rate required for digital audio is driven by a fundamental law of A/D conversion, referred to as the Nyquist Theorem. It states that in order to produce an accurate representation of a given frequency of sound, each cycle of a sound’s vibration must be sampled a minimum of two times, otherwise aliasing will occur. Because the range of human hearing is generally accepted to be 20Hz-20kHz, this law indicates that a sampling rate of at least 40kHz is required to capture full-frequency audio. Increasing the sample rate will increase the frequency response.

Question 3

Describe the relationship between bit depth and dynamic range in digital audio.

Answer 3

Bit depth determines the dynamic range of digital audio. By multiplying the bit depth by six, you can estimate the useful dynamic range of the system in dB. Therefore, the greater the bit depth, the greater the dynamic range.
