Add Distortion to Audio Online - Free
Add grit, warmth, or aggressive edge to your audio on purpose. This is creative distortion - soft clipping that shapes the waveform for a warmer or rougher sound. Low drive adds the kind of subtle saturation that makes vocals and instruments cut through a mix. High drive produces heavy crunch for lo-fi effects and sound design.

Problems This Tool Solves
I want to add warmth to my vocals without obvious distortion
Use a drive of 10–30. This range adds subtle saturation that makes vocals feel warmer and more present without any audible crunch.
I want the lo-fi vintage tape sound
Apply light distortion (drive 20–40), then use EQ to roll off everything above 8 kHz and below 200 Hz. The combination creates a warm, imperfect, analog feel.
Distortion made my audio harsh and painful
Drive is too high, or high frequencies are over-emphasized. Reduce drive, or apply EQ after distortion to cut the 5–10 kHz range.
Common Use Cases
Subtle vocal warmth
A drive of 10–30 adds gentle saturation that makes a voice feel present and slightly analog. This is the "secret sauce" that almost all professional mixes use on vocals.
Lo-fi / tape aesthetic
Mild distortion combined with a low-pass filter from the EQ gives audio that warm, vintage, imperfect sound.
Telephone or old radio effect
Heavy distortion plus EQ that cuts everything below 300 Hz and above 3 kHz simulates a phone line or AM radio.
Aggressive guitar or synth tone
High drive values create the crunch and sustain associated with overdriven amplifiers.
Make bass audible on phone speakers
Small speakers cannot reproduce deep bass, but they can play the harmonics that distortion generates above the bass frequency. Light saturation on a bass track makes it audible on phones and laptops that would otherwise miss it entirely.
How to Add Distortion to Audio Online
- Upload your audio file to the editor.
- Open Distortion in the Effects section. Set the Drive amount.
- Preview in real time. Start low (10–30) for warmth, go higher for crunch.
- Click Apply when you like the result. Export as WAV or MP3.
Distortion vs Saturation - Degree, Not Kind
Saturation (low drive)
Soft, subtle harmonic coloring. Adds warmth and presence without obvious crunch. Think analog tape or tube preamp.
Best for: vocals, warming up a mix, lo-fi aesthetic, making audio "sit" betterDistortion (high drive)
Aggressive clipping that fundamentally changes the character of the sound. Clearly audible and intentional.
Best for: guitar crunch, aggressive sound design, creative effects, telephone/radio simulationDrive Ranges by Effect
| Effect | Drive | Character |
|---|---|---|
| Subtle warmth / tape saturation | 10–30 | Barely audible. Adds harmonic richness. |
| Light overdrive | 30–60 | Noticeable crunch on peaks. Sounds "driven." |
| Medium distortion | 60–100 | Obvious grit. Good for lo-fi and guitar. |
| Heavy distortion | 100–150 | Aggressive. Sustained crunch. |
| Extreme / bitcrushed feel | 150–200 | Harsh and deliberate. For creative effect only. |
Quick Tips
- Start at a low drive and increase. It is much easier to add more distortion than to undo too much.
- If it sounds great, back off 10%. Distortion always sounds more intense on export than during preview.
- Combine with EQ to shape the distortion. Cut highs after distortion to remove harshness. Boost lows for a thicker grind.
- For the lo-fi effect: apply light distortion, then use EQ to roll off everything above 8 kHz and below 200 Hz.
- Apply to a selected region only for a dramatic transition or emphasis on a specific phrase.
Common Misconceptions
Myth: Distortion is always unwanted
Reality: Almost all professional vocal mixes use subtle saturation. At low drive levels it adds harmonic richness that makes audio sound warmer and more polished.
Myth: Distortion and clipping are the same thing
Reality: Hard digital clipping chops the waveform flat (harsh). This tool uses soft clipping, which curves the waveform gradually for a warmer, more musical sound.
Common Problems and Fixes
Audio sounds harsh and painful
Drive is too high, or high frequencies are being over-emphasized. Reduce drive, or apply EQ after distortion to cut the 5–10 kHz range.
Distortion made everything too loud
Distortion adds energy and can push the signal above 0 dBFS. Use Normalize after applying distortion to bring the level back under control.
Effect sounds nothing like a guitar amp
This is soft-clipping waveshaping, not amp modeling. It produces general-purpose saturation and distortion. For realistic amp tones, a dedicated amp simulator is needed.

Frequently Asked Questions
Is this the same as unwanted clipping?
No. Unwanted clipping is hard digital clipping - the waveform is chopped flat, creating harsh artifacts. This tool uses soft clipping, which curves the waveform gradually for a warmer, more musical sound.
What drive should I start with?
For subtle warmth on vocals: 10–30. For noticeable overdrive: 50–100. For heavy distortion: 100+. Always preview first.
Can I distort just part of a track?
Yes. Select a region on the waveform before applying. Only that section gets distorted. The rest stays clean.
How do I get the telephone or old radio sound?
Apply distortion at drive 50–80. Then use the Equalizer to cut everything below 300 Hz and above 3 kHz. The narrow frequency range plus distortion creates the classic phone effect.
Do professional mixes really use distortion on vocals?
Yes. Almost all professional vocal mixes use subtle saturation (drive 10–30) to add harmonic richness and presence. It is not audible as "distortion" - it just makes the vocal feel warmer and more forward in the mix.
What is bitcrushing?
Bitcrushing reduces the bit depth and sample rate of audio, creating a crunchy, lo-fi, retro digital sound - like old video game consoles or early samplers. This tool produces analog-style soft clipping. For bitcrushing specifically, use extreme drive settings combined with EQ.
I want to REMOVE distortion from my audio, not add it. Where do I go?
This tool adds creative distortion on purpose. Removing unwanted distortion (clipping from overloaded recording) is a different problem and much harder. If the distortion is mild, the Equalizer can help by cutting harsh frequencies (2–8 kHz). Severe clipping damage is generally not repairable with simple tools.
How do I make the telephone or old radio voice effect?
Two steps: apply distortion at drive 50–80 for grit, then use the Equalizer to cut everything below 300 Hz and above 3 kHz. The narrow bandwidth plus distortion perfectly recreates the filtered, compressed sound of a phone line or AM radio.
