What's included
Smart Noise Reduction
Adjustable noise gate removes background noise — fans, AC hum, keyboard clicks, and room ambience. Control the strength from subtle to aggressive.
Auto-Normalization
Automatically levels your audio to a consistent -1dB peak volume. No more quiet sections or sudden loud spikes.
EQ Presets
Three carefully tuned EQ presets: Clarity (boosts vocal presence at 3-6kHz), Warm (rich low-end body), and Bright (airy high-end sparkle).
100% Private
All processing happens locally in your browser using the Web Audio API. Your audio files are never uploaded to any server.
Instant Processing
Enhancement runs in seconds — no waiting for cloud processing. Upload, configure, process, and download immediately.
Lossless WAV Export
Download the enhanced audio as a lossless WAV file with zero quality loss from the processing pipeline.

Professional Audio Enhancement — Free in Your Browser
Clean up any voice recording with three powerful processing stages in one tool. First, the noise reduction stage uses an intelligent dynamics compressor and high-pass filter to gate out background noise — fans, AC hum, keyboard clicks, and room ambience. Second, the EQ stage applies carefully tuned frequency adjustments: the Clarity preset boosts the 3-6kHz speech intelligibility range, Warm adds low-end body at 200Hz, and Bright lifts airy high frequencies above 5kHz. Third, auto-normalization brings your audio to a consistent -1dB peak, eliminating volume inconsistencies. All processing uses the Web Audio API OfflineAudioContext for maximum quality, and your files are never uploaded to any server.
When to Use Audio Enhancement vs. Noise Removal
Our Audio Enhancer and Noise Remover tools serve different purposes. The Noise Remover is a focused, single-purpose tool that removes background noise from recordings using spectral gating. The Audio Enhancer is a multi-stage processing pipeline that combines noise reduction with EQ and normalization — it is designed to make your recording sound better overall, not just quieter. Use the Noise Remover when your recording has specific noise issues (fan hum, AC buzz) but otherwise sounds fine. Use the Audio Enhancer when you want to polish a recording end-to-end — clean up noise, add vocal presence, and normalize volume in a single step.
Enhance Voice Recordings in MP3 or WAV — Cleanup, Level, and EQ
Upload a voice recording, podcast, meeting, interview, or voice memo and improve it in one browser workflow. Use Speech Cleanup to reduce background noise while you talk, turn on Voice Leveling to make quiet and loud phrases more consistent, then choose Clarity, Warm, or Bright tone shaping. Compare the original and enhanced result at the same point before saving a smaller MP3 or a lossless WAV. Your recording is processed in your browser and is not uploaded for enhancement.
Frequently asked questions
What kinds of audio can I enhance?
The enhancer works best with voice recordings — podcasts, voiceovers, meeting recordings, interview audio, and voice memos. It can also improve the clarity of music recordings, though it is optimized for speech frequencies.
Is this audio enhancer free?
Yes, free to use with no limits on file size or number of files. No signup, no credit card, no watermarks on your output.
How does the noise reduction work?
The noise reduction uses a combination of a dynamics compressor (acting as an intelligent noise gate) and a high-pass filter to remove low-frequency rumble. Adjusting the strength slider controls the gate threshold — higher values cut more noise but may also reduce quiet speech. Start at 50% and adjust up or down based on your recording.
