## Overview

Scans audio with FFmpeg silence detection plus PCM window analysis to find short dropouts, sudden gaps, and likely recording interruptions.

## Inputs

- **Audio File** (file): Select an audio file
- **Silence Threshold (dB)** (number)
- **Minimum Dropout Duration (s)** (number)

## 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

- Upload your audio file to the analyzer.
- Set the silence threshold in decibels (dB) and the minimum dropout duration in seconds.
- The tool runs FFmpeg silence detection and PCM window analysis to locate signal drops.
- Review 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.

## Frequently asked questions

### 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.
