Free Tool
Graphic EQ Simulator & Preset Exporter
Move ten bands, hear the change instantly over royalty-free music (or your own file), and watch the response curve redraw live. When you like it, export a preset that drops straight into Equalizer APO, AutoEQ, Wavelet, Poweramp, or any tool that reads a parametric/graphic EQ file. Everything runs in your browser - nothing is uploaded.
Auto pre-amp: 0.0 dB

Export your preset
Graphic-EQ bands export as parametric peaking filters at the ISO centre frequencies (Q 1.4), which is exactly how Wavelet and Poweramp store a 10-band curve. The auto pre-amp offsets the largest boost so nothing clips.
FAQ
EQ simulator - questions
What the bands do, which export format your app wants, and why nothing is uploaded.
How do I use the EQ presets in Equalizer APO, Wavelet, or Poweramp?
Set the curve here, pick your app from the export dropdown, and copy or download the file. For Equalizer APO / Peace, paste the lines into config.txt (or import it in Peace). For Wavelet or Poweramp, save the ParametricEQ.txt and import it as an AutoEQ profile. Each band is exported as a peaking filter at the standard ISO centre frequency, which is exactly how those apps store a 10-band graphic EQ.
What is the auto pre-amp value and why does it matter?
Boosting any band raises the peak signal level, which can clip (distort) digitally. The auto pre-amp applies a matching negative gain to the whole signal so the loudest boosted band stays at or below 0 dBFS. Every export includes the pre-amp line; keep it - removing it is the most common cause of EQ distortion.
Is a 10-band graphic EQ enough, or do I need parametric?
For tone-shaping by ear - more bass, less treble, a vocal lift - ten bands at octave spacing is plenty and far easier to dial in. Parametric EQ matters when you are correcting a narrow headphone resonance or a single room mode and need a precise frequency and Q. This tool exports its bands as parametric filters, so you can take the curve into a parametric app and fine-tune from there.
Does my audio get uploaded when I load my own file?
No. The file is decoded and processed entirely in your browser with the Web Audio API; it never leaves your device and is not stored. The same is true of the synthesised test tracks - everything is generated and played locally.
Why use peaking filters at fixed frequencies instead of shelves?
A graphic EQ models the whole response as a series of overlapping peaking (bell) filters at fixed centres, which sums to a smooth curve and maps 1:1 to the bands in Wavelet, Poweramp, and hardware GEQs. Shelves behave differently at the extremes, so keeping everything as peaking filters means the exported preset reproduces the curve you hear here.
