Hi, I suggest to add an advanced audio setup for following scenarios for conversion to MKV: 1: Separate settings for different audio tracks: E. g. I want to keep the original audio for my preferred language (German). For a secondary language (English) I want to convert the audio to AAC or AC3. This will save alot of HDD capacity because mostly the English track is Dolby True HD or DTS-HD while the German track is DD5.1 or DTS5.1. 2: Higher bitrate settings for AAC conversion: I suggest to allow a higher bitrate settings (e. g. 192, 256, 320 kbps) for a better audio quality when converting to AAC or AC3. This would be great for all videos that are based on a high sound quality while the player has no DTS or Dolby True HD playback capability. So PLEASE, add this features to CloneBD!
