Voice equalizer: fix a muddy, boxy or nasal voice
Load a voice recording, or record one, and Toola shows where your voice sits by frequency, says in plain words what stands out — muddy, boxy, nasal, harsh or muffled — and suggests a fix. Move six zones with sliders named for what you hear, add a high-pass or low-pass filter in Hz, compare with the original at the same loudness, and save a WAV, an MP3 or the video with the new sound. Nothing is uploaded.
Private: your files never leave your device.
A recording stays in your browser. Noise suppression and auto-gain are switched off so you hear your real voice.

Frequently asked questions
How does it know my voice is muddy or nasal?
It listens to the loud, speech-like parts of your recording, measures how much energy sits in each frequency range and compares that with the typical balance of a speaking voice. It is a rule of thumb: your voice, microphone and room are unique, so use the suggestions as a starting point and trust your ears.
What do the frequency ranges mean?
Below 100 Hz is mostly rumble. 100–400 Hz is the body of the voice (too much is muddy, too little is thin). 400–800 Hz is where boxiness lives. 800–1,500 Hz is the nasal range. 1.5–5 kHz carries clarity (too much is harsh, too little is muffled). Above 12 kHz is air.
Which setting is safe for any voice?
A high-pass filter at about 80 Hz removes desk thumps and room rumble without touching the voice. Beyond that, small moves of 1–3 dB are usually enough, and cutting a problem sounds more natural than boosting everything else.
Can it fix a video’s sound?
Yes. Choose “Video with the new sound” when you save: the sound is processed and put back, and the picture is copied without re-encoding.
Is my recording uploaded?
No. Analysis, playback and saving all happen in your browser. Recording uses your microphone only while you press record, and nothing leaves your device.
