A plea... Deanna and I have been running this site since 2008 and lately we're seeing a big increase in users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free download site only works if everyone chips in to offset the revenue that ads on other sites bring in. Please donate at the bottom of the page. Every little bit helps. Thank you so much. Sincerely, your Older Geeks: Randy and Deanna Always scroll to the bottom of the page for the main download link. We don't believe in fake/misleading download buttons and tricks. The link is always in the same place. Audio Fake Detector PRO v7.7 👉 Detects fake high-quality audio files by identifying lossy-to-lossless transcodes using advanced spectral and statistical analysis. Audio Fake Detector PRO detects fake high quality audio files, including lossy sources such as MP3 or AAC that have been transcoded or disguised as lossless formats like WAV or FLAC. Audio Fake Detector PRO uses a hybrid analysis engine combining spectrogram-based detection and statistical verification depending on the file type. Lossy formats are analyzed using frequency cutoff behavior, abrupt endings, stereo anomalies, and majority-vote segment analysis, while lossless formats are verified using auCDtect statistical analysis. Each audio file is divided into multiple segments and independently evaluated to reduce false positives and false negatives caused by mixed-quality content. Detailed reports are generated in several formats, and suspicious files can automatically be moved into a dedicated folder while preserving the original folder structure.  Features: Detects lossy-to-lossless and lossy-to-lossy transcodes Hybrid analysis engine using spectrogram and statistical methods Multi-segment majority voting system for improved accuracy Spectral cutoff and compression artifact detection Joint stereo anomaly detection Automatic download and use of ffmpeg, ffprobe, and auCDtect Metadata recovery with multi-step fallback analysis Fast spectrogram processing with optimized implementation Intelligent segment selection to reduce processing overhead Generates reports in LOG, CSV, and HTML formats Moves suspicious files to ~Fake while preserving folder structure Supports hidden files and batch folder analysis 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 Note: Automatically downloads required tools on first run: ffmpeg and ffprobe (audio decoding and analysis), and auCDtect (lossless audio verification) Note: 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). Supported operating systems: Windows 10, Windows 11 Supported languages: English Changes: v7.7 06-14-26 [fix] Resolved a display bug in the final summary where the resume counter showed an incorrect starting file index (e.g., "10 of 9"). [imp] Info line now shows full technical metadata: codec name, sample rate (kHz), channel count (Nch), bit depth if available (lossless only), bitrate, duration last. Examples: Encoder: reference libFLAC 1.3.4 │ flac │ 44.1 kHz │ 2ch │ 24 bit │ 1411 kbps │ 00:08:13 Encoder: LAME3.100 │ mp3 │ 44.1 kHz │ 2ch │ 320 kbps │ 00:04:01 Bit depth only shown when > 0 (unavailable for lossy formats). [fix] Reason string for auCDtect-compromised context rule corrected: "auCDtect already flagged anomalies (SKIP/MPEG)" -> "auCDtect returned SKIP or MPEG". [fix] Critical: rescan loop was infinite. Files processed in the first pass were never added to the processed list, so every rescan found the same files again. Fixed by recording each file in the processed list at the very start of its processing, before any analysis or skip logic. [imp] Engine line and info line are now separate: Line 1 (DarkGray/DarkMagenta): Full analysis label + Engine type Line 2 (DarkCyan): Encoder tag (or "No encoder tag") + kbps + hh:mm:ss Eliminates the wrap problem when encoder tags or paths are long. Applied also to files rejected by the bitrate pre-filter (< 170 kbps). DarkMagenta used for "Full analysis (>= 170 kbps) | Engine: spectrogram (lossy)" and for Hi-Res and 48 kHz bypass engine lines and for "New files detected" rescan messages. DarkCyan used for the info line. [new] Encoder tag extracted from file metadata (format-level or stream-level) and shown on the info line. Always shown: either the tag value or "No encoder tag". Applies to all formats and all engine paths. [imp] Source quality stratification in FAKE reason strings and classification thresholds (spectrogram fallback path for standard lossless 44.1/48 kHz): <= 13 kHz : low-quality lossy source (e.g. MP3 <= 128 kbps) 13-17.2 kHz : mid-quality lossy source (e.g. MP3 160/192 kbps) 17.2-20.5 kHz: high-quality compressed source (e.g. MP3 320 kbps / VBR V0) 20.5-22 kHz : 44.1 kHz standard source Threshold raised from 20000 to 20500 Hz: MP3 320 kbps and VBR V0 can reach 20-21.5 kHz. Note: for 44.1 kHz files this path is taken only when auCDtect is unavailable or returned too few readable segments. When auCDtect works normally its own verdict (MPEG/CDDA %) is shown instead. For 48 kHz files the spectrogram engine is always used (auCDtect bypassed). [new] Resume box now uses Unicode double-border characters (╔ ╠ ╚ ║). [fix] Redundant "Standard 48 kHz Lossless detected" log line removed from the internal context function - already shown on the Engine line. [fix] Rescan after analysis now always shows "Rescan complete: no new files found." in dark grey so the user knows the check ran. [fix] Resume N-branch: full fresh disk rescan instead of reusing stale file list. Files moved to ~Fake in previous session now correctly excluded. Message changed to "Rescanning folder..." to reflect actual behavior. [fix] When declining resume (answer N), file index counter reset to 0. [fix] Resume box [char] * Int multiplication not valid in PowerShell 5.1; fixed using [string][char] * Int. [chg] Encoder absent now shown as "No encoder tag" instead of being omitted. [chg] Rule A2-RMS-SUSPECT reason: "avg rms" -> "average rms", spacing adjusted.  Note: This file has one hit on VirusTotal. We have confirmed this to be a false positive. The file is safe.
