Codec
A codec is a essential tool in radio broadcasting that converts audio signals into digital format for transmission and then back into sound. Think of it like a translator that helps radio stations send their content over the airwaves or internet efficiently. There are different types of codecs, such as MP3 or AAC, which are like different languages for audio compression. Radio stations and broadcasters use codecs to maintain good sound quality while using less bandwidth, similar to how you might compress a large photo to send it by email without losing too much quality.

Example Interview Questions
Senior Level Questions
Q: How would you handle codec failure during a live broadcast?
Expected Answer: A senior engineer should explain backup systems, quick troubleshooting steps, and having emergency protocols in place. They should mention alternative transmission methods and how to minimize downtime.
Q: What factors do you consider when selecting codecs for different broadcast scenarios?
Expected Answer: Should discuss bandwidth availability, audio quality requirements, delay tolerance, and cost considerations. Should also mention compatibility with existing equipment and reliability needs.
Mid Level Questions
Q: Explain the difference between lossy and lossless audio codecs.
Expected Answer: Should explain in simple terms that lossless codecs keep all audio quality but take more bandwidth, while lossy codecs reduce file size by removing some audio data that humans usually can't hear.
