How to capture & process DTS from Laserdisc

[sebus]

Phonic Digitrack (http://www.phonic.com/en/digitrack.html) - on Windows 7 with Asio4All (or Mac OS X Maverick)

DTS from Laserdisc. It captures perfectly & in Reaper also plays back nicely to Onkyo Amp (via digital out)

ALSO plays back perfectly fine via external amplifier with foobar2000 & SPDIFER plugin (http://www.ga.cba.pl/spdif_w7.html)

AC3filter does NOT work on this, will give just digital noise!
Same for VLC

But besplit 0.9 b8 can not deal with this wave either

And how can I get just the .dts from it so it can be used in ie. DTS CD (or muxed to .mkv)

Here is the file (http://www.sendspace.com/file/oocdxk)

Thanks

At Videohelp, there is a guy from New York named vhelp who has lots of experience with LaserDiscs,
so probably he may help you faster than the doom9ers :)

An absolutely perfect USB hardware for LD DTS/AC3 capture is Esi Audio U24 XL.

Captures to perfect wav (DTS or AC3) which can be processed with no issue with besplit

But capture works only with Windows default drivers & asio4all

Eventually came across a unit that does allow me with minimal fuss LD to mkv conversion (both video & audio)
But it only works correctly under Windows 7 (did not work for me under Windows 10 LTSB 2016)

Tested with Pioneer Laserdisc & SY-P295N CV/SV to HDMI Converter and Scaler with Audio

SY-P295N outputs perfect HDMI stream (which I can watch on TV / Onkyo TX-NR609 directly OR via HDMI splitter iSolem [1080P FULL HD] 1x2 3D HDMI Switch Box (1 Input x 2 Output)

Supplied capture software is most odd, it has two sections in Encoder tab:

Seems that .ts for DTV is not used at all in this software with that device.
It only uses Analog section (most odd!)
It does hardware intel quick sync video h264 encoding on-fly, but on Ultrabook with i5 with the small samples I had no problems at all - bitrate if selectable)

To record the video/AC3 6ch best is to chose mkv (does not matter what is audio encoder, as it will recognize & record AC3 anyway)

I have tested other sources (DVD via HDMI from Professional HHB UDP-68 player & AC3 channels from Gigablue satellite unit),
HDCP is stripped completely - tested direct connection, no need for splitter

Sample of AC3 recorded clip is here (https://www.sendspace.com/file/vhjxxv)

To record DTS, one must chose avi & PCM in Audio Encoder (that is a bug in software, does not recognize correctly DTS stream)
Recorded clip does play back fine on hardware decoder (Onkyo TX-NR609)

But on PC (VLC) it does play static & Mediainfo recognizes it audio as PCM.
MPL-HC with build in AC3filter plays it fine 6 ch, but still shows PCM.

So the easiest is to extract audio with ffmpeg
ffmpeg -i DTS_capture.AVI -c copy extracted_dts.wav
Then process extracted_dts.wav with wav2dts from tebasuna51 on HA forum (https://hydrogenaud.io/index.php/topic,94988.msg934234.html#msg934234)
and just create .mkv with MKVToolNix GUI

But sadly that works only for short capture, my test was under 2 min long.
Capture of over 50 min seems to have PCM audio that can not be processed the same way

So all in all the hardware is OK if you need to do AC3 only capture! (which is what HD PVR 2 does anyway)
