How to analyze an audio file
Open Audio Analyzer with a local audio file when you need measurements instead of an edited copy. It shows a waveform and spectrogram, estimates BPM and key, and reports integrated loudness, RMS, peak, true peak, clipping, silence, stereo phase correlation, and dynamic range. The analyzer is read-only, so the source file stays unchanged.
Choose an audio analysis tool
This category has one tool. Use Audio Analyzer to examine one local audio file and record what its measurements show. If you need to change the file, use a page in Audio Tools for an editing task.
What Audio Analyzer measures
Audio Analyzer reports a waveform and spectrogram alongside the file's measurements. Its readouts include BPM and key estimates, integrated loudness, RMS, peak, true peak, clipping, silence, stereo phase correlation, and dynamic range.
BPM and key are estimates. The remaining readouts cover integrated loudness, RMS, peak, true peak, clipping, silence, stereo phase correlation, and dynamic range. Use the waveform and spectrogram as a visual reference next to those results.
How to inspect a local audio file
Use a recording, mix, or exported track as the local file to inspect. Audio Analyzer reads it in the browser and presents the waveform, spectrogram, and measurements on the page. The category is for local analysis with no upload, and the source file remains unchanged.
The analyzer reports what it finds. It does not edit the audio or create a replacement file, so any correction has to happen in another audio tool.
Where audio analysis comes up
- A mix can be checked for integrated loudness, RMS, peak, true peak, clipping, and dynamic range before a later editing or mastering step.
- A recording can be checked for silence and loudness when you need to identify sections for later editing.
- An exported track can be reviewed for BPM and key estimates with its waveform and spectrogram.
- A stereo recording can be checked for phase correlation when you need a measurement of its stereo relationship.
When to use Audio Analyzer instead of another audio tool
Use Audio Analyzer for inspection and measurement. Its outputs are visual views and readouts, and it leaves the source file unchanged. Use Audio Tools when the next step is to compress, convert, trim, clean, merge, tag, or record audio.
Frequently asked questions
What does an audio analyzer show?
Audio Analyzer shows a waveform, a spectrogram, BPM and key estimates, integrated loudness, RMS, peak, true peak, clipping, silence, stereo phase correlation, and dynamic range.
Can I analyze a local audio file in the browser?
Yes. Audio Analyzer analyzes a local audio file in the browser with no upload, and the source file is never changed.
Does audio analysis change the original file?
No. Audio Analyzer is read-only, so it reports measurements without replacing or editing the source file.
Can an audio analyzer find clipping and silence?
Yes. Audio Analyzer reports clipping and silence, alongside peak, true peak, loudness, RMS, and dynamic range measurements.
