<h2>What Is the Distortion Effect?</h2>
<p>
Distortion is a waveshaper that deliberately deforms the shape of an audio
waveform, adding new harmonics and producing the crunchy, gritty, buzzy, or
growling tone heard on electric guitars, rock vocals, lo-fi beats, and
sci-fi sound design. Audacity's built-in Distortion effect is an 11-in-one
processor that covers the whole distortion family in a single dialog &mdash;
from subtle tube-style overdrive and tape-like saturation to hard clipping,
fuzz, rectification, and vintage Leveller emulations. It works on any
selection, is fully previewable, and is free on Windows, macOS, and Linux.
</p>
<h2>How to Add Distortion in Audacity</h2>
<h3>Step 1: Select the Audio to Distort</h3>
<p>
Click and drag to select a clip, region, or press <code>Ctrl+A</code> /
<code>Cmd+A</code> for the whole track. Consider duplicating the track first so
you can compare the original against the distorted version.
</p>
<h3>
Step 2: Open Effect &rarr; Distortion and Modulation &rarr; Distortion
</h3>
<p>
Navigate to <strong
>Effect &rarr; Distortion and Modulation &rarr; Distortion</strong
>. The dialog opens with a Distortion type selector and the parameters that
apply to the selected type.
</p>
<h3>Step 3: Choose a Distortion Type and Adjust Parameters</h3>
<p>
Pick a type from the drop-down menu, then adjust the type-specific controls
(Clipping level, Drive, Hardness, Make-up Gain, etc.). Use
<strong>Manage &rarr; Factory Presets</strong> for ready-made tones like Fuzz
Box, Blues Drive, and Walkie-Talkie.
</p>
<h3>Step 4: Preview and Apply</h3>
<p>
Click <strong>Preview</strong> to hear the effect on a short sample. Adjust and
preview again until satisfied, then click <strong>Apply</strong>.
</p>
<h2>Distortion Types Explained</h2>
<h3>Hard Clipping and Soft Clipping</h3>
<p>
<strong>Hard Clipping</strong> cuts the waveform at a fixed threshold, producing
an aggressive, buzzy fuzz tone with strong odd harmonics. Controls: Clipping level
(-100 to 0 dB), Drive (0&ndash;100), and Make-up Gain.
<strong>Soft Clipping</strong> progressively reduces gain above the threshold,
rounding the peaks for a warmer, tube-amp style grit. Controls: Threshold, Hardness
(0&ndash;100), and Make-up Gain.
</p>
<h3>Soft, Medium and Hard Overdrive</h3>
<p>
Three smooth-curve shapers modelled on classic overdrive pedals. Soft
Overdrive adds gentle warmth. Medium Overdrive is a blues-style crunch. Hard
Overdrive is a rock rhythm tone. All three use Distortion amount
(0&ndash;100) and Output level (0&ndash;100).
</p>
<h3>Cubic Curve (Odd Harmonics) and Even Harmonics</h3>
<p>
<strong>Cubic Curve</strong> generates odd-numbered harmonics (3rd, 5th, 7th&hellip;)
for a classic valve-amp sound, with a Repeat processing control (0&ndash;5) for
extra intensity. <strong>Even Harmonics</strong> produces brighter, more musical
tube-style colour with a Harmonic brightness control and a DC blocking filter
to tame low-end rumble.
</p>
<h3>Expand and Compress</h3>
<p>
An S-shaped curve that pushes low-level signals further down and pulls
medium-level signals up. Useful as a creative dynamics effect on drum loops
and sound design.
</p>
<h3>Leveller, Rectifier and Hard Limiter</h3>
<p>
<strong>Leveller</strong> flattens dynamics in discrete steps &mdash; great for
lo-fi and radio-voice effects. <strong>Rectifier Distortion</strong>
progressively produces a half-wave then full-wave rectified signal for a ring-mod-style
octave-up character. <strong>Hard Limiter 1413</strong> lets you set a dB limit
and mix the clipped signal against the restored overshoot for controlled, colourful
clipping.
</p>
<h2>Distortion Parameters Reference</h2>
<h3>Clipping Level / Threshold (dB)</h3>
<p>
Sets the amplitude above which the waveform is cut (Hard Clipping) or
squeezed (Soft Clipping, Hard Limiter). Range: -100 to 0 dB. Lower values
clip more of the signal and produce heavier distortion; values near 0 dB
only clip the loudest peaks.
</p>
<h3>Drive and Hardness</h3>
<p>
<strong>Drive</strong> (0&ndash;100) boosts the signal before the clipping stage
&mdash; more drive means more distortion at the same threshold.
<strong>Hardness</strong> (Soft Clipping only, 0&ndash;100) controls how sharp
the clipping knee is; 0 is very smooth, 100 behaves almost like hard clipping.
</p>
<h3>Make-up Gain and Output Level</h3>
<p>
Clipping usually reduces perceived loudness. <strong>Make-up Gain</strong>
(clipping types) and <strong>Output level</strong> (overdrive and harmonic types)
restore the final volume after processing. Keep an eye on the waveform to avoid
exceeding 0 dB.
</p>
<h3>DC Blocking Filter and Repeat Processing</h3>
<p>
<strong>DC blocking filter</strong> removes the DC offset that asymmetric waveshaping
can introduce &mdash; leave it on unless you are deliberately creating broken
signals. <strong>Repeat processing</strong> (Cubic Curve) re-applies the algorithm
0&ndash;5 times for thicker, more saturated tones.

<h2>Common Use Cases</h2>
<ul>
<li>
<strong>Distorted guitar</strong> — Cubic Curve or Hard Overdrive on clean DI
guitar tracks
</li>
<li>
<strong>Rock / scream vocals</strong> — Soft Clipping at -12 dB with moderate
Drive
</li>
<li>
<strong>Lo-fi hip-hop</strong> — Leveller for stepped, vintage-sounding vocals
and samples
</li>
<li>
<strong>Fuzz bass</strong> — Hard Clipping with low threshold and high Make-up
Gain
</li>
<li>
<strong>Glitch / sound design</strong> — Rectifier and Hard Clipping for extreme,
broken textures
</li>
<li>
<strong>Walkie-talkie / radio voice</strong> — Leveller plus a band-pass EQ
for telephone realism
</li>
<li>
<strong>Tape saturation</strong> — Even Harmonics with low Distortion and DC
filter on
</li>
<li>
<strong>Mastering colour</strong> — Hard Limiter 1413 at -3 dB with partial
Residue level for gentle glue
</li>
</ul>
<h2>Tips for Best Results</h2>
<ul>
<li>
Always work on a duplicate track &mdash; Distortion is destructive once
applied
</li>
<li>Use Preview to audition each Distortion type before committing</li>
<li>
Input signals above 0 dB are always hard clipped regardless of chosen type
&mdash; lower the clip with Amplify first if needed
</li>
<li>
Follow Distortion with an EQ (low-cut at 80&ndash;120 Hz, presence boost
at 2&ndash;4 kHz) to shape the final tone
</li>
<li>
Use the factory presets (Fuzz Box, Walkie-Talkie, Blues Drive) as starting
points and tweak from there
</li>
<li>
Combine small amounts from two types (e.g. Soft Clipping + Even Harmonics)
by applying them sequentially for richer harmonics
</li>
</ul>
<h2>Frequently Asked Questions</h2>
<p>
<strong>Where is the Distortion effect located in Audacity?</strong><br />
Go to <strong
>Effect &rarr; Distortion and Modulation &rarr; Distortion</strong
>. The dialog offers 11 types in a drop-down menu plus sliders for
type-specific parameters.
</p>
<p>
<strong>What distortion types does Audacity support?</strong><br />
Hard Clipping, Soft Clipping, Soft Overdrive, Medium Overdrive, Hard Overdrive,
Cubic Curve (Odd Harmonics), Even Harmonics, Expand and Compress, Leveller, Rectifier
Distortion, and Hard Limiter 1413 &mdash; 11 types in total.
</p>
<p>
<strong
>What is the difference between overdrive, distortion and fuzz?</strong
><br />
Overdrive is mild, tube-style saturation (Soft or Medium Overdrive). Distortion
is heavier, more compressed (Cubic Curve or Hard Overdrive). Fuzz is extreme,
square-wave-like clipping (Hard Clipping with low threshold and high Drive).
</p>
<p>
<strong>How do I make a guitar sound distorted in Audacity?</strong><br />
Record a clean DI guitar, select the track, and open the Distortion effect. For
a classic rock tone try Cubic Curve with Distortion amount ~50 and Repeat processing
1. For heavier tones try Hard Clipping at -20 dB with Drive 50. Follow with EQ
for cabinet-style shaping.
</p>
<p>
<strong>Why does my audio sound quieter after applying distortion?</strong
><br />
Clipping and waveshaping reduce peaks. Raise Make-up Gain (for clipping types)
or Output level (for overdrive types) to compensate.
</p>
<p>
<strong>Can Audacity remove distortion from a recording?</strong><br />
Not fully &mdash; once a signal has been clipped, lost information cannot be recovered.
Audacity's Clip Fix effect can smooth short, mild clipped peaks, but for severe
distortion a dedicated declipping tool or a fresh recording is needed.
