Analyzing Audio Gain and Dynamic Range
This gain analyzer measures your audio file's peak level (dB), RMS level (dB), dynamic range (dB), and average gain. All processing happens in your browser—no upload required.
Peak level shows the loudest instant in your file. RMS (Root Mean Square) indicates average power. Dynamic range is the difference between the quietest and loudest parts. Average gain provides an overall level reference.
Who Needs Gain Analysis
- Musicians who check if their mix has enough headroom before mastering. They verify peak levels stay below -6 dB to avoid clipping.
- Recordists who recorded audio that sounds too quiet or too loud. They measure to understand the actual levels before adjusting.
- Podcasters who ensure their episodes have consistent gain across multiple recordings. Analysis reveals which files need adjustment.
- Audio engineers who diagnose dynamic range issues. Too much range means quiet parts are inaudible; too little means everything is squashed.
- Broadcast preparers who check that levels meet industry standards (-23 LUFS for some regions, specific peak limits).
What to Know Before Using It
- Peak level above 0 dB means clipping (distortion). Professional recordings typically peak between -6 and -1 dB.
- RMS level indicates perceived loudness better than peak. A file can have low peaks but high RMS (heavily compressed).
- Dynamic range tells you about the recording's dynamics. High range (20+ dB) means wide dynamics; low range (under 5 dB) means heavy compression.
- This is a measurement tool, not a fix. Use the normalizer, compressor, or volume adjuster to actually change gain.
- The analysis covers the entire file. It doesn't show how gain varies over time.
FAQ
- What's a good peak level?
- For final releases, -1 to -3 dB peak is common. For files that will be further processed, -6 dB peak leaves headroom.
- What RMS level should I aim for?
- Depends on the content. Podcasts: around -18 to -16 dB RMS. Music: varies widely, -18 to -8 dB RMS depending on genre and style.
- What does dynamic range tell me?
- High dynamic range (15+ dB) means quiet and loud sections—typical of classical music. Low range (under 5 dB) means consistent loudness—typical of modern pop or heavily compressed audio.
- Is higher dynamic range better?
- Not necessarily. It depends on the content and intent. Speech benefits from moderate compression. Some music genres rely on wide dynamics.
- Can this detect clipping?
- Yes—if peak level is at or above 0 dB, your audio is clipped (distorted). This can't be fixed, only prevented in future recordings.
- How is this different from loudness measurement?
- Gain analysis focuses on electrical levels (dB). Loudness measurement (LUFS) approximates human perception. Both are useful for different purposes.
