Fine-tune music, voice and recordings without uploading
Use ten independently adjustable EQ bands with adjustable peaking-filter width, compare your changes to the original signal, and inspect a live frequency spectrum. Music production, podcast clean-up, instrument practice and listening adjustments often benefit from gentle cuts and boosts rather than extreme changes. The frequency response graph illustrates the filters’ theoretical gain, while the live spectrum shows the decoded playback signal.
What does the EQ change?
Low frequencies add weight or reduce rumble; mid-range bands influence clarity and tone; high frequencies influence presence and brightness. EQ cannot reliably remove isolated background voices, restore lost audio information or guarantee loudness compliance.
What will my download contain?
A rendered, uncompressed WAV from the full decoded recording, including every channel. Selecting peak protection attenuates a recording if its rendered peak exceeds −1 dBFS. This is peak attenuation, not a limiter or a loudness-normalization service.
Supported files & privacy
Import support depends on the browser’s audio decoders. Exports are WAV only. Preset/setting files contain no audio. The original file never leaves your device, and decoded audio is cleared when resetting the editor.
Using Audio Equalizer Studio
Shape locally decoded audio with ten fixed EQ bands, compare original and processed playback, then export WAV or portable settings.
Workflow
Open audio your browser can decode
adjust ten bands and preamp while checking spectrum and A/B playback
render and audition WAV, optionally export settings JSON without audio.
Example
For speech, try a modest low-band reduction for rumble, A/B the same phrase, export WAV and reopen it in your audio editor.
Limits and data handling
Decoding depends on browser codecs and AudioContext. Offline rendering caps at 24 million samples and may not be interruptible. Peak attenuation to −1 dBFS is not a true-peak limiter. Settings JSON excludes audio. Check the WAV for clipping in your target software.
FAQs
Does settings JSON include the recording?
No. It stores EQ settings; audio is a separate WAV export.
Does peak attenuation prevent all clipping?
No. It is not a true-peak limiter; inspect the exported signal.
