Tool usage guide
The Audio True Peak Meter analyzes audio files to measure true peak levels using FFmpeg's loudnorm analysis, helping prevent clipping and ensure loudness safety for broadcast, streaming, and mastering workflows.
Background
A music producer is finalizing a track for streaming services and needs to ensure no clipping occurs on consumer devices.
Problem
The mastered track might have hidden inter-sample peaks that exceed safe levels, risking distortion.
How to use
Upload the WAV file to the Audio True Peak Meter without changing the default ceiling.
Outcome
The tool reports a true peak of -0.8 dBTP, confirming adequate headroom, and the track is approved for distribution.
Background
A podcast editor is preparing an episode for upload and must meet the platform's true peak requirement of -1 dBTP.
Problem
The episode audio could have peaks above the limit, leading to rejection or poor audio quality.
How to use
Upload the MP3 file and set the ceilingDb to -1 dBTP in the options.
ceilingDb: -1Outcome
Analysis shows a true peak of -1.3 dBTP, within limits, and the episode is ready for publishing.
True peak is the maximum reconstructed audio level in dBTP, accounting for inter-sample peaks that can cause clipping during digital-to-analog conversion.
The tool uses FFmpeg's loudnorm filter, which provides reliable true peak analysis based on standard audio processing algorithms.
Common formats like MP3, WAV, FLAC, and others compatible with FFmpeg are supported for analysis.
No, the tool analyzes one audio file at a time. For batch processing, run separate analyses for each file.
The ceilingDb option sets a target true peak level in dBTP. The analysis reports headroom below this ceiling to help avoid clipping.
