How to make a recording easier to listen to

QUICK ANSWER

Add the audio or supported video recording and listen to the original. Decide whether you are preparing speech, a podcast or music. Process, listen to the real result and choose an output format before downloading.

A useful audio enhancement often needs several small adjustments rather than one strong effect. Audio Enhancer combines presets with noise reduction, EQ, compression, de-essing and loudness controls, so you can tune a recording to its purpose.

1. Open your file

Add the audio or supported video recording and listen to the original. Decide whether you are preparing speech, a podcast or music.

2. Work through the settings

  1. Choose Clear voice, Podcast or Music as a starting preset, or use Custom controls.
  2. Adjust noise reduction and EQ gently. Check that removing a low rumble has not made the sound thin.
  3. Use compression and loudness controls to manage level differences, and de-essing when harsh “s” sounds need attention.
  4. Process, listen to the real result and choose an output format before downloading.

3. Check before you share

  • Listen to both loud and quiet parts.
  • Check for distortion, pumping or a flattened musical sound.
  • Compare at a similar playback volume and keep the original.

File limits and first-use notes

Up to 8 files, 350 MB combined, 10 minutes combined source duration and 350 MB combined output. DSP enhancement runs locally; clipped or missing source information cannot be recovered. Free, without registration or time limits; file and device limits still apply.

Questions you may have

Do I need an account to enhance audio?

No. Audio Enhancer is permanently free without registration or a session time limit. File, duration and device limits still apply.

Can it repair a recording that was too loud at the microphone?

Clipping destroys information. Enhancement can change the remaining sound, but cannot guarantee restoration of the missing peaks.
