What Does This Equalizer Do?

A graphic equalizer lets you boost or cut specific frequency ranges in an audio file — more bass, less harsh treble, more presence in the vocal range, and so on. This tool gives you 10 independent bands from 32 Hz up to 16 kHz, the same standard layout used by most music players' built-in EQ.

Pick a preset to get started quickly, or drag any slider to fine-tune — dragging automatically switches the preset to "Custom" so it's always clear what you're hearing.

🔊 External Speaker Boost

Built for Phone & Laptop Speakers

Small speakers can't reproduce real bass, which makes audio sound thin when played out loud instead of through headphones. This preset compensates with a speaker-tuned EQ curve, plus a loudness/clarity boost so the track still cuts through in a noisy room, car, or outdoors. It's independent of the EQ curve — leave it on with any preset or custom setting.

Frequently Asked Questions

Is the equalizer really free?
Yes, completely free. No trial period, no credit card, no catch.
What does External Speaker Boost actually change?
Two things: an EQ curve tuned for small speakers (less wasted sub-bass energy the speaker can't reproduce anyway, more low-mid warmth to compensate, more presence in the upper mids), and a loudness/dynamics stage (gentle compression plus a limiter) that makes quiet passages easier to hear and raises overall perceived loudness without clipping. It's a separate toggle from the EQ curve, so you can combine it with any preset or your own custom sliders.
Can I combine a genre preset with Speaker Boost?
Yes — Speaker Boost is an independent checkbox, not tied to any one preset. Pick Jazz, Pop, or any other preset (or your own custom curve), and toggle Speaker Boost on top of it.
What audio formats can I upload?
You can upload MP3, WAV, FLAC, M4A, AAC, OGG, AIFF, WMA, Opus, AMR, APE, WavPack (WV), and most other common audio formats. You can also upload video files (MP4, MOV, MKV, AVI, WebM, FLV, WMV, MPG, 3GP, and more) — we'll automatically extract the audio track. Maximum file size is 100 MB for audio, 1 GB for video.
What format is the output file?
The EQ-adjusted track is delivered as a high-quality MP3 file.
