  • added support for DTS-HD Master Audio 7.1 tracks (only 5.1 decoding)
  • little performance boost for PAL speedup/down on DualCore CPUs
  • fixed some bugs
Version 2.02
  • Release Date: Nov 21, 2007
  • fixed: automatic registering of the dtsac3source filter crashed
Version 2.01
  • Release Date: Nov 19, 2007
  • new "-debug" switch added
  • fixed: automatic registering of the dtsac3source filter crashed
  • fixed: AC3 encoding sometimes crashed when being fed 24 bit audio data
  • fixed: AC3 encoded files were invalid when being fed 24 bit audio data
  • eac3toGUI didn't work with eac3to v2.0
  • "eac3to source.ac3 dest.ac3 -slowdown" didn't do anything useful
  • when a crash occurs, the bug report is automatically copied to clipboard now

  • can extract DTS core from DTS-HD tracks
  • can remove DTS zero padding and repair outdated DTS-ES headers
  • can apply positive or negative delay to decoded audio data
  • can reduce bitdepth of decoded audio data by using TPDF dithering
  • can resample decoded audio data (using "r8brain")
  • can apply/reverse PAL speedup on decoded audio data (using "r8brain")
Version 1.23
  • Release Date: Oct 5, 2007
  • bugfix: sometimes TrueHD decoding resulted in incorrect sampling rate
Version 1.12
  • Release Date: Aug 6, 2007
  • The tools "flac.exe", "aften.exe" and "sox.exe" are now distributed in the eac3to zip to make your life a bit easier.
  • Correct channel mapping for 7.1 LPCM tracks is default now.
  • The new option "-down6" allows downconverting of 7.1 tracks to 5.1 (this option is activated by default for AC3 and DTS encoding).
  • I'm shipping a modded "flac.exe" with eac3to now, which has no problems with 2GB file output, anymore!! As a result the flac encoding by eac3to should now be more or less perfect.
  • Fixed a number of bugs.
Version 1.8
  • Release Date: Jun 6, 2007
  • now has a GUI and it supports PCM input.
