Laserdisc PCM Bit Perfect Testkit
I've been meaning to start on some tutorials for capturing and syncing laserdisc audio, but I figured this is a good place to start since this test is essential to a capture setup. So what is it and how does it work? DTS encoded CDs allow 5.1 channel playback via a standard CD on supported equipment (if you listen to a DTS CD on a car CD player it will just sound like noise). The reason it is of interest to us is because it can only be decoded from a capture that is bit perfect. So the basic idea is that you burn the DTS test CD, capture it through your laserdisc player, decode back to a DTS stream, and then cross your fingers it sounds like music and not garbled noise Smile This testkit is the custom DTS test CD I made, DTS Parser v2 (included for posterity since his website has been down for a long time), and the directions below.

1. Burn bin/cue to CD-R. ImgBurn is suggested with a Taiyo Yuden CD-R (I had issues with cheap CD-Rs during testing)
2. Capture and export as 16-bit, 44.1 kHz, Stereo PCM (WAV)
3. Run DTS Parser 2.0
4. Check "Rebuild Stream" checkbox
5. Click "Add DTS file..."
6. Select DTS WAV (.wav) from file type dropdown in bottom right
7. Select your captured WAV from Step 2
8. Click "Start Batch"

If everything works ok you should see the progress bar fill to about 75% and be left with a .dts file around 4:14 (37.5MB). If the progress bar doesn't fill, the file is empty, or you hear noise instead of smooth elevator grooves then something went wrong.

I'm going to be adding another test CD with a setup check I found on the end of a Laserdisc. It goes through all the channels with a voice and tones, so I figured it'd be useful to help make sure you have everything setup correctly (particularly for analog captures). If anyone has any other suggestions please let me know.
