dts/ac3 in WMA ?

[pieroxy]

Hi all,

I know it is possible to fit an AC3 or DTS track into a wav or avi file for playing with media player (and AC3Filter or ffdshow). Is it possible to do it with a wma file?

The reason I am asking is that I need WMP to be able to play the file (running Windows Media Center) and I'd like the ability for WMP to tag the file (artist, album, etc...). AFAIK, wav does not support tags (such as ID3 for mp3)

That way, I would have all my 5.1 music available in Media Center just fine.

Thanks

AFAIK, ID3 tags are container-independent - meaning in theory, they can be applied to any bitstream format / container. (Mp3s, for example, aren't even in a container - the ID3 tag is applied to the raw mp3 bitstream.) Whether windows media center will let you apply them to DTS is another question.

As far as DTS in WMA, I believe that all of microsoft's container formats are based off ASF. I have no idea whether ASF supports DTS or not, but if I was to attempt this I would open a DTS file in graphedit and attempt to connect it to an ASF muxer.

Thanks for your answer. Do you know of any ASF muxer I could use? Is there one already in WinXP?

Then I shall connect it to a disk writer?

Thanks

I wanted to add my 2 bits since what I said is not really true.

I know an ac3 file can be "converted" to a WAV file by just adding the WAV header (besweet with -addriff), but this won't work for dts... How can I play a dts file in WMP, other than embedding it in an AVI file?

There might be a way with AC3Filter since the latest versions support DTS... Any ideas?

Try it with besplit: besplit -core ( -input "file.dts" -output "dts.wav" -type dts -addriff )

I couldn't do it with besplit, as it outputs a huge number of errors.

Anyways, I got it working with VDubMod :), in the stream list add the dts stream and click on "Save WAV".

Now I am having another issue on my dts-cd files which are 44.1KHz: AC3Filter will not let it through SPDIF...

When I open a 44.1 dts file with graphedit and then get the properties I see input as "dts 44.1" and there is only PCM on my SPDIF. When I try with a 48 dts file, I see input as "dts 48" and I have dts out on my SPDIF... Any ideas?

gspot tells me that both these files are 5 channel.

I'd really like to be able to play these dts-cds on my media center.... :(

Thanks

Stupid question:

WMA - is this a raw audio stream, or "Audio encoded with a WMA codec" already packaged in a Windows Media container?

Because: I can imagine "a stream inside a container", e.g. a DTS or AC3 stream inside a WMV container - but I'm not sure if WMA is/has a container at all.

[pieroxy]

There is no such thing as a stupid question ;)

WMA is the same as WMV with only audio, which in turn is the same as ASF. It is the new container from MS that succeeded to AVI. It can contain different streams such as video (from various codecs) and audio (again, different codecs).

It is the only container I know that allows WMP to store informations such as those included in an ID3 tag, along with MP3 of course (which is not a container).

So AC3 inside WMA shall very well be possible, but still needs to be done...

DTS inside WAV is still not much use because WAV doesnt have the same tag properties that WMA has (Artist, Album, etc.) Is there any solution to this problem yet? I also have the same issue as the OP.
