dts->wav->mkv
I prefer professional DD 5.1 (AC3) conversion of DTS. (cinemas use Dolby Digital! Nowadays dts is only blu-ray avertising feature...) Certified DD is much better for home devices (tv, tablets, notebooks) because of switchable compression.
So far I used a simple eac3to batch file to make a 6 channel wav. But because of the wav size (>2GB), no editor can read the wav header properly. The trick: mkvtoolnix reads big wav files, no channel mismatch! The wav file has to be muxed with mkvtoolnix to mkv. This audio mkv can be read by certified converters ->Mainconcept Totalcode Studio. Certified Dolby Digital (ac3) files include 3 "versions" of the stream, that ffmpeg cannot: uncompressed standard compression (line) heavy compression at -20 dB for noisy enviroment, notebooks etc. with downmix params and a specified dialog level (standard -27 dB). So I ask to add the feature to BD3D2MK3D: Convert DTS audio tracks to WAV-MKV for further processing. Important eac3to parameter: -no2ndpass Otherwise spikes require 2nd pass with lower volume. That is not necessary, you don't hear interferences. Last edited by frank; 17th December 2015 at 15:23. |
