This free online audio equalizer is a 10-band EQ that works in your browser. Add files, choose presets or bands, optionally use advanced filters, and download in your chosen format.
Why Use an Equalizer?
An equalizer lets you shape tone by boosting or cutting specific frequency bands. Use it for more bass, clearer vocals, or brighter treble — with waveform preview and full output options.
Uses for EQ
- Music: Bass boost, treble clarity, or genre presets
- Voice & podcasts: Vocal preset or custom mids for clarity
- Content & video: Match tone across clips or fix dull recordings
- Playback: Compensate for weak speakers or headphones
How the Equalizer Works
The tool applies high-pass/low-pass and shelf filters (optional), then the 10 EQ bands, then output gain — all client-side — and exports to your selected format/bitrate/sample rate.
What this tool offers
- Waveform view for original and equalized audio
- Play from cursor and native audio controls
- 10-band EQ with presets
- Advanced filters and output gain
- Batch processing and ZIP download
Tips and best practices
- Start with a preset: Choose Bass Boost, Vocal, or Rock, then fine-tune.
- Avoid extremes: Small adjustments often sound better than large ±12 dB moves.
- Same format: Use Same as input when you don’t need to convert.
- Prevent clipping: Use negative output gain after strong boosts.
