Bit Depth
Bit Depth is a way to measure sound quality in digital audio recording and production. Think of it like the detail in a photograph - higher bit depth means more detailed and clearer sound, just like higher resolution means a clearer picture. When sound engineers talk about bit depth (sometimes called "audio resolution" or "sample depth"), they're referring to how accurately the digital recording captures the original sound. Common standards are 16-bit (used for CDs) and 24-bit (used in professional recording studios). This concept is important in music production, radio, TV, film sound, and any industry where high-quality audio is needed.

Example Interview Questions
Senior Level Questions
Q: How do you decide what bit depth to use for different projects?
Expected Answer: A senior engineer should explain how they consider factors like the final delivery format, storage requirements, and quality needs. They should mention industry standards like 16-bit for CDs and 24-bit for professional recording, and explain the trade-offs between quality and file size.
Q: How do you handle bit depth conversion in a professional workflow?
Expected Answer: Should discuss managing quality throughout the production chain, proper dithering techniques when converting between bit depths, and maintaining quality standards for different delivery formats.
Mid Level Questions
Q: What's the difference between 16-bit and 24-bit recording?
Expected Answer: Should explain in practical terms how 16-bit is CD quality with 65,536 possible values, while 24-bit offers much more detail with millions of values, and when each is appropriate to use.
Q: How does bit depth affect the noise floor in recordings?
Expected Answer: Should be able to explain how higher bit depth allows for lower noise and better quality in simple terms, with practical examples from their experience.
Junior Level Questions
Q: What is bit depth and why is it important?
Expected Answer: Should be able to explain that bit depth determines how accurately digital audio captures sound, using simple analogies like photography resolution.
Q: What are common bit depth standards in the industry?
Expected Answer: Should know that 16-bit is standard for CDs and consumer audio, while 24-bit is used in professional recording and production.
