FAQ

Common questions

If you do not see your question here, the support team replies within one business day.

  • It adjusts the whole recording so its loudness sits at a consistent target, rather than jumping between quiet and loud. It is the difference between a listener adjusting the volume repeatedly and never thinking about it.
  • Normalizing changes the overall level of the file. Compression narrows the gap between the loudest and quietest moments inside it. Most spoken audio benefits from a little of both.
  • Most podcast platforms target around -16 LUFS for stereo and -19 LUFS for mono. If you are not sure, aim for consistency first: it matters more than hitting an exact number.
  • Raising a level cannot bring back detail that was already clipped during recording. Hilite lifts the level without pushing the peaks past the point where they break up.
  • MP3, WAV, M4A, AAC, and FLAC.
  • Yes, free to start. Larger files and some export options need a free Hilite account.
