FLAC problems

[mikehadfield]

I have recently tried the DTS-HD MA to FLAC conversion feature but am having a problem.

It creates the FLAC file OK, no errors encountered, but when playing back the resulting file there are intermittent crackles, pops and whistles.

I have tried this on a number of different BDs (Star Trek TNG episodes, Titanic, ET) and all suffer the same problem.

Are you using Arcsoft with this? By far, I've seen issues like this already.

I too get similar problems. Converting from DTS-HD MA 5.1 with Arcsoft's dll 1.1.0.8 and 1.1.0.9. I get crackles in very loud moments (clipping?). Is there a remedy for this?
<edit>
I did try converting with eac3to and it gave out the exact same problem. What the hell?

If you're playing these files on a WDTV Live SMP or similar then you should know that they simply can't handle vigorous use of full 24 bit FLAC. Try them in VLC and see if the crackling is still there.

To fix this re-encode the audio with Eac3to using this command line:

Code: Select all

"d:\eac3to\eac3to.exe" "%~f1" "%~n1.flac" -down16 -log=NUL

Which will down-convert it to 16 bit, and for the moment if you're using the WDTV Live SMP on 6.1 audio:

Code: Select all

"d:\eac3to\eac3to.exe" "%~f1" "%~n1.flac" -down16 -double7 -log=NUL

because the current firmware doesn't like 6.1 audio in an MKV.
