Inspect file size, supported original WAV headers, decoded duration, channel peaks, RMS, DC offset and stereo correlation locally.
No file selected.
Up to 128 MiB per file; decoded audio up to 256 MiB (about 23 min mono / 11½ min stereo). Formats depend on your browser's decoder. Working decode uses 48 kHz; original WAV header parameters are listed separately.

Your waveform will appear here.
Load audio to choose a section.
Play/pause, seek on the waveform or use the adjacent time and jump controls. This previews decoded working audio without changing the report. Peaks and RMS describe samples, not true peak or LUFS.
Playback stopped.
Original codec details are not inferred from a filename or the 48 kHz working decode.
Choose audio or try the sample to inspect it.
Original parameters are verified only for supported, consistent RIFF/WAVE headers within a bounded 64 KiB scan. Other codecs and bit depths are not guessed. Decoding can resample or change duration. File size / decoded duration is an approximate average file rate including metadata. Full-scale sample counts do not prove previous clipping. Correlation is undefined for a silent channel. Reports include the selected filename; nothing is sent to a server.
Your audio is never uploaded to a server. Capture, decoding, analysis and file generation happen locally in your browser using self-hosted code, without an account or audio history.
Supported consistent RIFF/WAVE headers can establish declared PCM/float encoding, channels, rate, depth and data length. Inspection reads at most 64 KiB and 128 chunk headers. For other formats or unsupported headers, original parameters are not guessed from MIME, extension or decoded samples.
All existing audio tools decode into a shared 48 kHz browser working buffer. It can differ from the original file rate. Original WAV header details are shown separately; compressed codec details may remain unknown.
No. Sample peaks are not true peaks; RMS is not LUFS. Counts at or beyond full scale describe current decoded samples and do not prove earlier clipping. Correlation is an uncentered sample relationship, undefined for silence in a channel.
File bytes times eight divided by decoded duration, including metadata and container overhead. It is an average file-rate estimate, not the original codec bitrate. Browser decoding may also affect measured duration.
One file up to 128 MiB, supported by your browser decoder, with mono/stereo decoded float samples within 256 MiB. Analysis has a 30-second deadline. Header inspection is bounded; replacing, cancelling or clearing terminates analysis and ignores stale results.
