Overview

The Audio Dropout Detector scans your audio files to identify brief signal dropouts, sudden silent gaps, and recording interruptions. By combining FFmpeg silence detection with PCM window analysis, it pinpoints the exact timestamps where audio drops below your specified decibel threshold, helping you locate and fix recording errors.

When to use

Quality checking podcast or voiceover recordings for sudden signal losses or hardware hiccups.
Scanning digitized analog tapes to locate physical tape dropouts or oxide loss gaps.
Auditing exported master tracks before distribution to ensure no digital silence glitches occurred.

How it works

1Upload your audio file to the analyzer.
2Set the silence threshold in decibels (dB) and the minimum dropout duration in seconds.
3The tool runs FFmpeg silence detection and PCM window analysis to locate signal drops.
4Review the generated JSON report containing the exact start times, end times, and durations of all detected dropouts.

Use cases

Post-production quality control for audiobooks to flag mic disconnects or editing silences.
Broadcast monitoring to verify continuous audio feed integrity and signal presence.
Restoring archival audio by mapping physical tape dropouts for targeted repair.

Examples

1. Detecting Mic Dropouts in a Podcast

Podcast Editor

Background

An editor is working on a raw interview recording where the guest's wireless microphone occasionally cut out for fractions of a second.

Problem

Manually listening to a two-hour episode to find micro-gaps is highly inefficient.

How to use

Upload the WAV recording, set the Silence Threshold to -45 dB, and set the Minimum Dropout Duration to 0.1 seconds.

{
  "silenceThresholdDb": -45,
  "minimumDropoutSeconds": 0.1
}

Outcome

The tool outputs a JSON list of timestamps showing exactly when the wireless mic dropped out, allowing the editor to quickly patch those sections.

2. QC Check for Digital Audio Master

Mastering Engineer

Background

A mastering engineer needs to verify that a newly exported album track has no digital buffer underruns or silent frames.

Problem

Buffer underruns can cause tiny silent gaps (under 100ms) that might slip past a quick listen but ruin the release quality.

How to use

Upload the master FLAC file, set the Silence Threshold to -60 dB, and set the Minimum Dropout Duration to 0.05 seconds.

FAQ

What audio file formats are supported?

The tool supports standard audio formats including MP3, WAV, M4A, FLAC, and OGG.

How does the tool define a dropout?

A dropout is defined as any period where the audio signal falls below the specified decibel threshold for at least the minimum duration set.

What is the default silence threshold?

The default threshold is -42 dB, which is suitable for detecting most noticeable signal drops in standard recordings.

Can I detect very short glitches?

Yes, you can adjust the minimum dropout duration down to 0.02 seconds (20 milliseconds) to catch extremely brief interruptions.

Is my audio file stored on your servers?

No, your audio file is processed securely and is not permanently stored or shared.

  "silenceThresholdDb": -60,
  "minimumDropoutSeconds": 0.05
