Something is borked when using DTS, no matter if itīs Arcsoft or Sonic. With AC3-Track splitting/joining is ok.
As i can remember, the same BDīs using an older eac3to version < 2.58 doesnīt produce this errors.
A good try will be Conair/German BD. Try to assemble
the GERMAN DTS Track. On the cut point there is a loud
spike on the decoded file (destination format can be WAV or AC3 - result is the same) |
This should finally be fixed in the next build. The problem was caused by the RAW/PCM gap/overlap fixing code. The code was working just fine, but due to how LPCM sampling curves work, just removing a number of audio samples from an audio track can result in spikes. This problem doesn't seem to occur if the gap fixing is done on the AC3/DTS bitstream. Now the next version will contain a new post processing filter which will adjust the audio signal 0.5ms before and after the m2ts join points to make sure that there are no spikes in the final audio stream...
