Audio Quality Analyzer

What the audio quality score measures

The score combines several signals instead of judging quality from file format alone. A high-bitrate file can still be clipped, nearly silent, or heavily compressed. The analyzer looks at signal level over time, counts samples close to the digital ceiling, compares quiet and loud blocks, and estimates how much of the recording contains near silence.

Use the individual measurements as the main evidence. The score is a quick summary, while peak level, estimated loudness, clipping percentage, dynamic range, and noise floor explain why a file received that score.

How to read the results

Estimated loudness

LUFS describes perceived program loudness more usefully than a single peak value. A very negative result usually means the file will sound quiet beside typical online audio. This tool provides an estimate suitable for screening, not a certified broadcast report.

Peak level and clipped samples

Peak level shows how close the highest sample comes to 0 dBFS, the digital limit. Samples at or extremely near that limit can indicate clipping. A file can be quiet overall and still contain a few clipped transients, so both measurements matter.

Dynamic range, silence, and noise floor

Dynamic range estimates the difference between quieter and louder active sections. Too little can sound flattened; too much can make speech or music difficult to hear in a noisy place. Silence ratio finds very low-level blocks, while the noise-floor estimate helps reveal background hiss or room noise.

When this analyzer is useful

• Checking a voice memo before transcription or sharing.
• Finding out why one song or video sounds much quieter than another.
• Screening podcast, interview, lecture, or meeting audio for clipping.
• Comparing recording setups without uploading private material.
