Audio File Analyzer

Analyze audio files for volume levels, frequency content, duration, and quality metrics

Supports MP3, WAV, FLAC, OGG, M4A, and other common audio formats

Audio Analysis Guide

Understanding the Metrics

Peak Volume: Highest amplitude in the audio (0-100%)
Average Volume: Mean amplitude across the entire file
Dynamic Range: Difference between peak and average volumes
Sample Rate: Number of samples per second (higher = better quality)
Bit Rate: Amount of data used per second (estimated)
Dominant Frequency: Most prominent frequency in the spectrum

Quality Indicators

High Quality: 44.1kHz+ sample rate, good dynamic range
CD Quality: 44.1kHz, 16-bit, 1411 kbps
MP3 Standard: 128-320 kbps bit rate
Lossless: FLAC, WAV maintain original quality
Clipping: Peak volume at 100% may indicate distortion
Low Dynamic Range: May indicate over-compression

Privacy Note: All audio analysis is performed locally in your browser using the Web Audio API. Your files are never uploaded to any server and remain completely private.

Frequently Asked Questions

Is my audio file uploaded to a server?▼

No! All analysis is performed entirely in your browser using the Web Audio API. Your files never leave your device, ensuring complete privacy and security.

What audio formats are supported?▼

The analyzer supports all audio formats that your browser can decode, including MP3, WAV, FLAC, OGG, M4A, AAC, and WebM. Most modern browsers support a wide range of formats.

How accurate is the frequency analysis?▼

The frequency spectrum provides a visual representation of the audio's frequency content. While it's excellent for general analysis and comparison, professional mastering applications may require specialized software with higher precision.

What does "peak at 100%" mean?▼

A peak volume of 100% indicates the audio reaches maximum digital amplitude. This could potentially indicate clipping or distortion. For optimal quality, most audio professionals aim for peaks slightly below 100%.
