ffmpeg gui extract audio separate wav files

It just reports information but it even has its own flaws the developers won't address (giving lossy audio a bit depth,etc). Relying on MediaInfo is a pitall of many users. If we know what you are doing (commands/logs). It has no real bearing on what eac3to will do when you do something. MediaInfo shows 8 channels and 6 channels on a 7.1 DTS-HD stream because it's showing the lossless extension (7.1) and the internal core (5.1). If you use -down6 on a 7.1 source, the back channels get mixed into the side channels. Since you don't share your commands or process, we can only guess what you do. To use LAV instead, you have to invoke LAV manually with -lav switch (or something similar I don't use other codecs for DTS streams).Īs for the 7.1 to 5.1, that really depends on what you do. Only issue seems to be with DTSExpress formats. That's because the default uses DCAdec, which is superior to the other codecs. Does this mean I simply get the 6 channel 'core' of the 8 channel track? If I start with DTS HD 7.1 and end with FLAC 5.1, what happened to the other two channels? Do I lose the side channels but keep the back? Do I lose the back but keep the sides? Or are they somehow combined? Using MediaInfo, I've noticed that the DTS HD 7.1 tracks are listed as both 8 and 6 channel. So I have two questions.Ģ) Am I on the right track and can someone help me troubleshoot? I downloaded what I think is the most recent version and I haven't had much success.

I thought I read somewhere that Libav now supports the conversion of DTS HD 7.1 to FLAC 7.1.

I read that I could use the codecs from some external programs to transcode from DTS HD 7.1 to FALC 7.1 but it appears that neither one is available anymore (like ArCSoft). I've been doing some reading but I haven't found my answers yet. I have been using eac3to to do my conversion but only just noticed that my transcoded files only have FLAC 5.1 (I'm now at this). Most of the tools handle FLAC easily but not DTS HD 7.1. I've been doing a lot of video editing lately.
