Step 1: Choose how long you want your generated noise to be (its fully random and uses every possible byte for samples) and generate the reference WAV.
Step 2: Burn that WAV to disc, then record through Reaper. Leave a few seconds of silence on either side of the recording to ensure nothing is cut off.
Step 3: Export your recording from Reaper and use the Tester to compare it with the reference WAV from Step 1.

Nice! By the way, it's been discussed previously by @schorman already updated wav2dts to use as a DTS Parser alternative: https://pastebin.com/GjspmX84

I'll be interested to play around with this new tool as well, thanks for putting that together.

Cool, glad to hear there's been improvements to that. The DTS parser is a good idea (I got the idea from someone on originaltrilogy.com), but it adds an unnecessary layer of complexity to what is basically just a bit comparison.

Did a few further tests today burning the reference track to Cd and ripping it. Hopefully someone can verify everything is good with their capture setup and I’ll update the main package.

Just sent a request to DL the new test kit @bronan

Cool, there's actually a download link below the screenshot on the previous page. Guess I hid it too well

edit: moved to before directions

Hahaha I did wonder. I briefly entertained the notion that Alex might be 80 and "request a download" was just old people speak for "click the link"

Haha when I click that link I get 'Access Denied' with the option to 'Request Access'

Oops! OK its unlocked now

Link has been updated with a new version of the app (1.0). It now has an option to check the headers against your reference as well (currently checks number of channels, bit depth, and sample frequency), as well as some code cleanup and optimizations.

Just updated the download to version 1.1. I incorrectly assumed all WAV headers were 44 bytes, leading to some files failing the format checks. That's been fixed now, and I also made the tool a little more agnostic so it could be useful for other purposes. The noise generator can now generate 8-24 bit depth, 8k-96kHz sample rate, and mono or stereo. I left the default to CD/Laserdisc standard for simplicity's sake. The Bit Perfect tester will also work with any spec uncompressed PCM files, so you could compare say two 24-bit 48kHz Mono PCM tracks from different Blurays releases or something if you wish.
