✍️ 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 type of reverb plugin algorithm simulates the acoustic characteristics of a real physical space by using recorded impulse responses?
Convolution reverb uses recorded impulse responses (IRs) of real rooms, halls, or hardware units and mathematically convolves them with the audio signal to recreate that space.
3. 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.
4. 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.
5. In audio editing, what does 'punch-in recording' allow you to do?
Punch-in recording lets you drop into record mode at a set point to replace a specific mistake while leaving the surrounding audio intact.
6. In spectral editing, what can an editor do that standard waveform editing cannot?
Spectral editing displays audio as a frequency vs. time spectrogram, allowing surgical removal of individual sounds like coughs or squeaks at their specific frequency and time location.
