✍️ Sample Audio Editing Questions & Answers
1. What does 'LUFS' measure and why is it important for streaming platforms?
LUFS measures perceived loudness; platforms like Spotify (-14 LUFS) and YouTube (-14 LUFS) normalize all content to a target, penalizing over-loud masters by turning them down.
2. Which mp3 file compression rate results in the highest audio fidelity:
MP3 compression is a lossy process, meaning it discards some audio information to reduce file size. A higher bitrate, such as 320 kbps (kilobits per second), means less information is discarded, resulting in a larger file size but significantly higher audio fidelity that is often indistinguishable from uncompressed audio for most listeners. Lower bitrates result in more aggressive compression and noticeable loss of quality.
3. What is 'phantom power' (+48V) required for in recording?
Phantom power (+48V) is supplied through the XLR cable to power the internal circuitry and capsule of condenser microphones.
4. What is the standard bit depth for CD-quality audio?
CD audio uses 16-bit depth, providing 65,536 possible amplitude values and approximately 96 dB of dynamic range.
5. Which of the following audio formats supports Variable Bit Rate (VBR) encoding?
MP3 supports VBR encoding, which allocates more bits to complex audio passages and fewer bits to simpler ones, optimizing quality and file size.
6. What does 'AAC' stand for in audio encoding?
AAC stands for Advanced Audio Coding, a lossy compression standard designed as a successor to MP3 with better quality at similar bit rates.
