Audio format support

Hi,

I see mka support a lot of various audio format but mkv less.

For mkv I use Flac ou wavpack to transcode losslessly dts-hd-ma or Dolby truehd but I see TAK is a way more effective for 24/48 multichannel input lossless transcode than flac/wavpack.

But TAK is not supported in mkv, is it only a lack of support or an impossible tak code support by its own structure?

Thanks.
