When archiving laserdiscs, we want to make sure we're copying exactly what is on the disc and not modifying it in any way. This cross-platform app is meant to help verify that your capture chain is setup correctly for "bit perfect" audio captures.
A bin/cue is included to burn to a CD, which is recorded through your capture setup. BitPerfect is then used to compare your recording to the reference and see if the samples in the stream are the same. There is also a noise generator included if you'd like a longer or shorter reference WAV, or you can just rip one of your music CDs and use a song. Just replace the reference.wav in the root directory with what you'd like to check against and you're ready to go.
Features:
- Easily test whether a digital recording is Bit Perfect or if 2 audio files are the same
- Snapshot feature analyzes WAV, FLAC, or RF64 (1.0 to 7.1 channels) for RMS, EBU R128 Loudness and Dynamic Range, Dual Mono, and 24-bit padding
- Noise Generator

Step 1: Burn the bin/cue to a CD-R (ImgBurn recommended)
Step 2: Play the CD-R on your LD player and record it through your capture setup. Leave a couple seconds of silence on either side of the recording when you export to ensure nothing is cut off (extra data before and after will not affect the test).
Step 3: Use the Tester to compare your recording with the reference WAV.

CHANGE-LOG
2.4 - Added Spectrogram markers/labels, various graphing tweaks
2.3 - Fixed Snapshot opening some Mono files with channel flagged as Center instead of Left, fixed opening some RF64 files, increased Inspector textbox size
2.2 - Added Snapshot Inspector to view .snaps, changed RMS to calculate for entire signal instead of per channel, more optimizations and cleanup
2.1 - Added FLAC support, added Snapshots, added surround sound support, fixed Extensible Wave reading, added EBU R128 meter for Loudness and Dynamic Range, rewrote dual mono check to work on analog sources, speed ups for sample reading, added peak/RMS/avg sample for channels
2.0 - Ported to Avalonia for cross-platform support. Rewrote testing logic to calculate sample values for matching. Added Stream From Disk and 24-bit matching support
1.4 - Added ability to ignore a percentage of the beginning and end when matching, extra info on completion messages
1.3 - Added pre-made reference CD, moved noise generator to separate tab
1.2 - Added dual mono check
1.1 - Fixed WAV header parsing, expanded noise generator settings
1.0 - Refactoring and memory optimizations, option to verify WAV headers match
0.9 - Initial release
