gosh, what a pain this is to find a proper way to check if you can bit-perfect capture. some hints were posted from members of the forum. but ultimately i found the right pieces of the puzzle and combined them to a working solution
test subject
dts audio cd from the eagles - hell freezes over
equipment
m-audio firewire 410
macbook pro running mac os 10.7.5
recording software
audacity
adobe audition
cockos reaper
other tools
dts parser
eac3to
so why dts? simply put: if you can successful capture the audio from dts-cd, then your capture is able to do bit-perfit recordings. the problem was which software and tools you need to have success. in my case it was a trial and error testing, which almost made me loose interst in the whole thing. there was no real guide out there, not even here, on how to test it properly.
that's lead me to test various software with no real success. but i kept looking and i finally found the answer. my recording software just didn't do it right or maybe i forgot something in the settings - feel free to add information that are crucial for proper dts-cd/ld audio recording - in audacity and adobe audition. i just couldn't get a proper file with these applications. i was making sure that i had 44.1khz and 16bit selected, but that seams not good enough. both failed for me.
then i came around another recording software. for shits and giggles i made a test recording and everything went the same way as the other two.
okay, now you wont be able to listen to the dts audio from the recorded wave file. that's where dts parser comes into play. i tried bsplit for my previous recordings, but it didn't work for me. probably because audacity and adobe audition didn't record the audio properly. so a new tool test my audacity and audition recording... nope, not working right. i had a half success, though... the "fixed" audio imported in eac3to showed dts information in it, but it was only 823kbits. so something was missing.
after continuing my search i found the right recording tool: cockos reaper. someone else did an extensive test on bit-perfect recording and he had success with this application. so i thought "lets give it a try." i made a 1 minute test recording with it and nothing new was seen. i exported the recording to a new wave file and send it to my windows machine. in dts parser i did fixing and low and behold a proper dts 5.1 audio file came out... SUCCESS AT LAST
so now i can officially say that i can capture bit-perfect :D
in short...
1. connect your device to your cd/ld player and to your computer
2. record audio at 16bit 44.1khz - for me it worked only in cockos reaper
3. export your recording to a wav file without any adjustments
4. open wav in dts parser, select rebuild stream and click start batch - app needs to be restarted for each new rebuild. i don't know why.
5. enjoy your dts file :)
