Make Audio Sound Better

Most bad audio is bad in one specific way — too quiet, too muffled, too harsh, or lurching between loud and soft. This tool gives you seven focused fixes rather than one vague “improve” button, so you pick the one that matches what is actually wrong. It works on any audio file: a voice recording, a piece of music, a podcast, a lecture, a field recording or a sound clip. Upload it, hear the change before you commit, and download the result. No sign-up and no watermarks.

How to Clean Up an Audio File

  1. Click the upload area above or drag and drop your audio file (up to 10 MB).
  2. Work out what is wrong with it — the list below matches symptoms to fixes.
  3. Choose that enhancement and preview it.
  4. Process and download the result as a WAV.

Start With What Is Wrong

  • Too quiet → Normalize
  • Volume jumps around → Compressor
  • A voice sounds distant or muddy → EQ (Voice)
  • Music sounds boomy or bottom-heavy → Hum Removal, which cleans up the deep bottom without thinning the music. Avoid EQ (Voice) here — it cuts far higher and will strip the bass out.
  • Low buzz or rumble underneath → Hum Removal
  • Hissy, piercing S sounds → De-esser
  • Bright, sharp or fatiguing overall → Low Pass Filter
  • Hiss, traffic, chatter, background noise → a different tool — see Reduce Noise

The Seven Enhancements

  • Normalize – lifts the whole recording until its loudest moment sits just under the ceiling. The fix for audio you can barely hear. It raises everything equally, so anything quiet stays quiet relative to the rest.
  • Compressor (gentle) – narrows the gap between the loud and quiet parts, then evens the result out. This is what makes a voice sit at a steady, comfortable level instead of making you reach for the volume control.
  • EQ (Voice) – the clarity one, and the name is the instruction: it is built for speech. It rolls off everything below about 250 Hz, where rumble and boom live, and lifts the range above 4 kHz where consonants are, so speech steps forward. This is usually the right choice to make a voice clearer. On music it is the wrong tool — a cut at 250 Hz takes the bass and the weight of the kick drum with it, leaving the track thin. For a boomy piece of music, reach for Hum Removal instead.
  • Hum Removal – cuts below roughly 70 Hz, which is where mains hum, air conditioning and desk rumble sit. Deliberately gentle, so it takes out the buzz without thinning the voice above it.
  • De-esser – pulls back everything above about 4 kHz, which is where sharp “s” and “sh” sounds live. Use it when sibilance is spiking uncomfortably in headphones.
  • Low Pass Filter – rolls off the top end from about 3 kHz upwards, softening a recording that is bright, thin or fatiguing to listen to. It will also dull the detail, so use it where harshness is the bigger problem.
  • High Pass Filter – a much heavier cut than Hum Removal, from about 1 kHz. It strips out the body of a voice as well as the rumble, leaving a thin, telephone-like sound. Treat it as a deliberate effect rather than a general repair; for rumble alone, Hum Removal is the one you want.

When You Might Need This

  • A voice memo recorded too far from the phone
  • A music track that is noticeably quieter than everything else in a playlist
  • An interview where one person is much louder than the other
  • A live or rehearsal recording that is boomy and needs tightening up
  • A lecture or meeting recording you can barely make out
  • A set of clips that need to sit at a matching level before you edit them together
  • A recording with a steady hum from a fan, fridge or laptop
  • A sound effect or sample that is too bright and sharp in the mix
  • Speech you are about to transcribe, where clarity improves the result

Frequently Asked Questions

Use EQ (Voice). Clarity is rarely about volume — it is about which frequencies are in the way. Speech becomes intelligible in the upper range, where consonants like t, k and s are formed, while the low end mostly carries weight and room rumble. The EQ trims the bottom and lifts the top, which makes a voice sound closer and more distinct without making it louder. If it still sounds distant afterwards, follow with the Compressor.

Try Normalize first — it turns the whole thing up until the loudest moment reaches the ceiling. If one loud cough or door slam is the only thing stopping it going louder, Normalize will not help much, because it is that peak setting the limit. In that case use the Compressor instead, which pulls the peaks down before lifting everything else.

This page shapes the sound you already have — its level, its tone, its balance. It cannot separate a voice from what is behind it. If the problem is something else in the recording — hiss, traffic, a fan, people talking in the background — that is a different job, and Reduce Noise is the tool for it. A useful order is to remove the noise there first, then come here to set the level and clarity.

Yes — download the result and upload it again with a different one. Because the output is uncompressed WAV, passing it through a second time costs you nothing in quality. A sensible order is to fix tone first (EQ, De-esser, Hum Removal), then set the level last (Compressor, then Normalize), since changing the tone changes how loud the result is.

Because it cuts from around 1 kHz, which is well above where a voice lives. A typical speaking voice has its fundamental between roughly 85 and 255 Hz, so this filter removes the body of the sound along with the rumble and leaves something like a telephone line. That can be exactly what you want for an effect. If your actual problem is a low hum or rumble, use Hum Removal, which cuts much lower and leaves the voice intact.

Only up to a point, and it is worth being honest about which point. Quiet, uneven, boomy or harsh audio usually improves a lot, because the information is all still there and simply badly balanced. Audio that is distorted, clipped, or recorded so far away that the room drowns the voice has lost information that no amount of filtering brings back. If you cannot make out the words at all, re-recording will beat any amount of processing.

No. Every enhancement here adjusts loudness or frequency balance only — the pitch, the speed and the length of your audio come back exactly as they went in. If you do want to change pitch or timing, Voice Effects and Change Speed are the tools for that.

You get an uncompressed WAV, so a small MP3 going in can come back considerably larger — that is normal, and it keeps the enhancement from being degraded by another round of compression. Uploads are limited to 10 MB. To turn the result into an MP3, run it through Convert Audio.
