What you need

  • The recording as an audio file: MP3, WAV, M4A, OGG, Opus, FLAC or WebM.
  • A browser on a computer or phone. Chrome, Edge, Safari and Firefox all work.
  • Headphones, if you have them, so you can hear small changes.

Step by step

  1. Open the file in Wow My Voice. It opens in your browser; nothing is uploaded.
  2. Start with the Clean Voice preset. It turns on AI noise suppression, a gentle gate, EQ and compression together.
  3. Listen, then flip Original / Enhanced. If the voice sounds thin or watery, lower Noise Suppression a little. If you still hear the room, raise it.
  4. For a fuller, radio-style voice, try the Podcast preset. For a recording that is already good, Studio adds only a light polish.
  5. Trim the start and end, and cut any long silences, in the editor.
  6. Export. Pick the target for where the audio is going: Podcast (−16 LUFS), YouTube (−14 LUFS), Voiceover (−19 LUFS) or Call, then MP3 or WAV.

How to improve the voice tone

If the voice is clean but still does not sound good, the tone is usually the issue. In Advanced mode, the EQ controls are where to look:

  • Muddy or boomy: turn down the low-mids (around 200–400 Hz).
  • Dull or muffled: add a little presence (around 3–5 kHz).
  • Harsh or hissy: turn the top end down slightly.
  • Thin: add a touch of low end, but not so much that it booms.

Small moves work best. Compare with the original after each change.

Common mistakes

  • Too much noise suppression. It is tempting to push it to the maximum, but the voice starts to sound underwater. Use the lowest setting that hides the noise.
  • Making it loud by raising the gain. That causes clipping. Let the export loudness target do it; it has a limiter built in.
  • Exporting MP3 and then editing again. Each MP3 encode loses a little. Keep a WAV until the very end.

Record better next time

Enhancement works best on a decent starting point. Record close to the mic (a hand’s width away), in the quietest, softest room you have: curtains, a sofa and a rug all cut echo. Turn off fans and notifications, and leave a second of silence at the start.
