Audio Fake Detector PRO

[Goa Trance]

I would like to submit a free utility I developed.

Audio Fake Detector PRO is a lightweight tool I created to analyze audio files and detect fake MP3 or FLAC files that have been transcoded from lossy sources but falsely appear as high-bitrate or lossless.

It is mainly intended for verifying the authenticity of audio files downloaded from online sharing platforms such as SoundCloud, where files are often mislabeled or re-encoded.

The software uses spectrogram-based analysis along with FFmpeg and auCDtect to identify:

- frequency cutoffs typical of compressed audio
- inconsistencies within different parts of the same file
- possible lossy-to-lossless transcodes
- Classification criteria (FAKE detection logic v5.4)

A file is classified as FAKE in the following cases:

- Bitrate < 170 kbps (pre-filter)
- Lossy formats (MP3/M4A/AAC/OGG/OPUS/WMA) with a hard cutoff ≤ 16.5 kHz
- Lossless formats (FLAC/WAV/APE/AIFF/WV) showing strong MPEG artifacts (auCDtect ≥ 80%)
- Lossless files with abnormal spectrogram cutoff behavior
- Mixed-source encoding or inconsistencies between segments

It is designed for modern digital music collections and large batches of audio files, including long recordings. It may be less accurate on audio with naturally limited frequency range (speech, very old recordings, acoustic material).

The program is completely free (freeware) portable and developed by me.

Probably false positives but I would not run it on my computer.

Thanks for the info! It looks safe.

What's new
- ffmpeg update check throttled to once per day.
A timestamp ($ToolDir\ffmpeg_check.stamp) is written after each successful check; subsequent launches within the same calendar day
skip the GitHub / gyan.dev HTTP call entirely, cutting startup time by ~1-3 s on slow connections.
The stamp is updated only when the check actually completes (network failures do not reset the 24-hour window)
- Exe builded with PS2EXE
