WaveCheck is a forensic audio quality analyzer for Windows. It decodes a file in pure Rust (no FFmpeg), measures it to broadcast spec, and tells you at a glance whether it's a genuine master or an upscaled fake. Spectral-cutoff-vs-Nyquist detection exposes MP3s renamed to FLAC; ITU-R BS.1770-4 / EBU R128 loudness, 4× oversampled true-peak, bit-depth utilisation, stereo correlation, and an STFT spectrogram fill in the full forensic picture. Scan a whole library in parallel, sort and search the results, then triage with rubber-band select and bulk move / delete. Everything runs 100% offline — your audio never leaves the machine, and analysis never modifies a file.
What it does
Good to know: Patent-encumbered and niche formats with no production-quality pure-Rust decoder are detected and reported rather than guessed at — WMA, Musepack, Monkey's Audio (APE), TTA, WavPack, MPEG-4 ALS, and DST-compressed DSD.
Windows 10/11, x64, about 7 MB. Free for personal use; commercial use needs a license.
Listed in
Fake-lossless detector
Maps the real spectral cutoff against Nyquist.
Spectrum + spectrogram
A 2048-pt Hann FFT spectrum plus a full STFT heatmap.
Broadcast loudness
ITU-R BS.1770-4 K-weighting and EBU R128 integrated LUFS + loudness range, locked to the libebur128 reference coefficients.
4× true-peak
Polyphase Kaiser-windowed-sinc oversampling catches inter-sample peaks that clip a DAC even when the raw sample peak reads under 0 dBFS.
Forensic fingerprints
Real bit-depth utilisation vs declared, per-window L/R correlation, DC offset, clipping, bit-rot, and an audio SHA-256 that ignores container repacks and tag edits.
Parallel folder scan
Rayon-parallel scan of a whole library.
DSD + every common format
WAV / AIFF / CAF, FLAC / ALAC, MP3 / AAC / Vorbis / Opus, Matroska — plus pure-Rust DSD (.dsf / .dff) decoding.
100% offline + read-only
No network, no telemetry, no uploads.

Check the traffic stats of Tapatch WaveCheck on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Tapatch WaveCheck on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Tapatch WaveCheck's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Tapatch WaveCheck on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.
