1. A recording has steady hiss and a soft speaker. What should guide the denoising strength?
   • Minimize all audible hiss even if quiet word endings disappear
   • Reduce hiss while checking that weak speech remains intelligible
   • Choose the preset that maximizes output loudness
   • Judge success only by a lower background-noise score
2. Why keep an untouched recording and the settings used for enhancement?
   • A saved preset proves that no speech component changed
   • A compressed export can reconstruct the original exactly
   • An enhanced clip alone is enough if noise sounds lower
   • They allow comparison and reversal of an overaggressive processing step
3. After aggressive denoising, final consonants audible in the original are absent from the processed clip. What likely happened?
   • The model suppressed weak speech components along with the noise
   • A uniform loudness adjustment lowered speech and hiss equally
   • Dereverberation removed delayed room reflections while preserving direct speech
   • The export changed only sample rate without altering the speech signal
4. A processed clip sounds cleaner. Which claim requires more evidence?
   • This listener notices less distracting noise in the processed playback
   • The processed version sounds different from the original
   • No quiet word endings or other original details were lost or altered
   • The chosen setting changed the audible result
5. Why listen to the final encoded file as well as the editing preview?
   • To confirm only that metadata tags were saved, without judging the sound
   • Encoding, level changes, and playback conditions can reveal new artifacts
   • To use the encoder’s file-size report as a proxy for speech clarity
   • To compare loudness numbers only, without listening for speech detail
6. A recording may affect a consequential decision. Which practice does the guide recommend?
   • Rely on the enhanced version alone once its noise level drops
   • Discard the source to avoid conflicting interpretations
   • Let the denoiser determine the speaker’s intended words
   • Retain the original and obtain appropriate expert review
7. Why define the enhancement goal before applying effects?
   • Every available effect improves the same audio property
   • A louder file is always easier to interpret
   • Noise reduction, dereverberation, equalization, and loudness changes address different problems
   • The first processing step makes later listening unnecessary
8. In the guide’s example, denoising removes a quiet speaker’s final consonants. What is the best next step?
   • Compare the same passage with the original and reduce strength or try another method
   • Raise only the final output volume
   • Overwrite the original so there is one version to review
   • Keep the result if the hiss meter improved
