Dithering
Dithering is a sound quality improvement technique used in professional audio work. Think of it like adding a very tiny amount of pleasant background noise to make digital audio sound smoother and more natural, similar to how photographers might add a slight grain to photos to make them look better. Sound engineers use dithering when converting high-quality audio to lower quality formats (like making a CD from a studio recording) to maintain the best possible sound quality. It's a standard step in professional audio production, mastering, and post-production work.
Examples in Resumes
Applied Dithering techniques to improve audio quality in final masters for major label releases
Implemented Dithering processes in digital audio workflow to maintain sound quality during format conversion
Trained junior engineers in proper Dithering application for professional audio mastering

Example Interview Questions
Senior Level Questions
Q: How do you decide which dithering algorithm to use for different types of audio material?
Expected Answer: A senior engineer should explain how different types of music or audio content might require different dithering approaches, mentioning real-world examples and how they affect the final sound quality.
Q: How would you explain dithering to a client who is concerned about adding noise to their recording?
Expected Answer: Should demonstrate ability to explain technical concepts in simple terms, using analogies and focusing on the benefits to sound quality rather than technical details.
Mid Level Questions
Q: What are the common mistakes people make when applying dithering?
Expected Answer: Should discuss practical issues like applying dithering multiple times, using wrong settings, or applying it at the wrong stage of the production process.
Q: When in the production process should dithering be applied?
Expected Answer: Should explain that dithering is typically done as the final step when reducing bit depth, usually during mastering or final export.
Junior Level Questions
Q: What is the basic purpose of dithering?
Expected Answer: Should be able to explain in simple terms that dithering helps maintain sound quality when converting high-quality audio to lower quality formats.
Q: In what situations would you need to apply dithering?
Expected Answer: Should mention common scenarios like preparing audio for CD production or creating MP3s from high-resolution files.
