Overview
The Audio Declicker is an online utility designed to restore audio quality by removing unwanted clicks, pops, and impulsive noises. Whether your audio suffers from vinyl record scratches, digital buffer underruns, or microphone interference, this tool isolates and repairs transient spikes without compromising the underlying sound.
When to Use
- •When digitizing vintage vinyl records or shellac discs that suffer from physical scratches, dust, and surface pops.
- •When repairing digital audio recordings that contain buffer dropouts, clock sync errors, or digital clicks.
- •When cleaning up vocal tracks or podcasts containing sharp mouth clicks, saliva noises, or sudden microphone plosives.
How It Works
- •Upload your audio file in WAV, MP3, FLAC, AAC, OGG, or M4A format.
- •Select your click detection threshold, burst threshold, and detection method based on the severity of the noise.
- •The algorithm analyzes the waveform to detect sudden, high-frequency transient spikes that deviate from the surrounding audio.
- •The tool interpolates the damaged samples to seamlessly reconstruct the waveform and outputs a clean, restored audio file.
Use Cases
Restoring digitized vinyl LP tracks by eliminating crackles and pops caused by dust and scratches.
Cleaning up podcast interviews recorded with low-quality microphones or digital connection glitches.
Preparing archival audio recordings for remastering by removing historical impulse noises.
Examples
1. Restoring a Digitized Vinyl Record Track
Archivist- Background
- An archivist is digitizing a rare 1970s vinyl record. The resulting WAV file contains noticeable pops and crackles due to minor surface scratches.
- Problem
- The surface noise distracts from the music, but manual spectral editing of hundreds of clicks is too time-consuming.
- How to Use
- Upload the digitized WAV file, set the Click Detection Threshold to 'Medium', set the Burst Threshold to 'Medium (5 samples)', and select the 'Adaptive' detection method.
- Example Config
-
audioFile: vinyl_rip.wav, clickThreshold: medium, burstThreshold: medium, method: adaptive - Outcome
- The tool successfully removes the sharp pops and crackles, leaving a clean, continuous musical track with no audible artifacts.
2. Fixing Digital Buffer Clicks in a Podcast
Podcast Producer- Background
- A podcast producer receives a guest's audio track recorded remotely. Due to a CPU spike during recording, the audio has periodic digital clicks and dropouts.
- Problem
- The digital clicks sound harsh and unprofessional to listeners.
- How to Use
- Upload the guest's MP3 track, set the Click Detection Threshold to 'High (Aggressive)', set the Burst Threshold to 'Short (2 samples)' to target tiny digital spikes, and choose the 'Fixed' detection method.
- Example Config
-
audioFile: guest_interview.mp3, clickThreshold: high, burstThreshold: short, method: fixed - Outcome
- The harsh digital clicks are completely eliminated, restoring smooth vocal continuity for the final podcast episode.

FAQ
What audio formats are supported by the Audio Declicker?
The tool supports WAV, MP3, FLAC, AAC, OGG, MP4, and M4A audio files up to 50MB.
What is the difference between Adaptive and Fixed detection methods?
Adaptive adjusts the detection threshold dynamically based on the surrounding audio volume, while Fixed uses a constant threshold throughout the entire file.
Will declicking degrade the overall quality of my music?
No, the algorithm target-repairs only the brief impulsive clicks lasting a few samples while leaving the rest of the audio spectrum untouched.
How do I choose the right Click Detection Threshold?
Use 'Low' for light clicks to preserve high frequencies, 'Medium' for general restoration, and 'High' or 'Very Aggressive' for heavily damaged recordings.
What does the Burst Threshold setting do?
It defines the duration of the click to be removed, ranging from short (2 samples) to long (10 samples), or disabled for single-sample spikes.
