There is no Speex DirectShow filter yet, and i dont think the interest in that is big enough that anybody from the team will look at it. If there is one made by somebody else, we may look at it.

BTW, using the Speex ACM codec from Christian Buchner, you can mux Speex into MKV/MKA as an A_MS/ACM audio track, and play it back, but its no native track then ....

So far I don't see much demand for Speex as it is made for low bitrate voice compression. Like Chris said, I don't think we'll work on that anytime soon.

well, i think it's perfect for audio-commentaries

and the lack of demand might be because it's very unknown

It would be cool to do but I have no time to worry with that just at the moment. I am working on fixing my own demuxer layer again so I can play with encoding and so forth. Maybe I will write a speex pacetizer one day but first i have to have an ogg demuxer written...so i'm guessing not until summer.

speex in matroska - why not ?

hi there,

Speex in matroska - interesting subject


i think its only partially suited for commentaries - because not only the directors voice is in the stream - but also the main movie audio - though at a lower volume ------> due to that the speex file will sound OK for the voice part - but very poorly on the rest.

never the less - WebCam/SecurityCam recordings featuring Speex in Matroska (with some highly compressable video format) would make sense.

yes there is: http://www.speex.org/download/speexDS_setup.zip , but oviously buggy

the rather old ACM codec - works nicely:
http://www.openacm.org/

there should be a tool which losslessly inserts a .spx into a wav container and vice versa (just like DTS or FLAC)


BUT a more urgent matter is rather the Speex in Ogg implementation than the Speex in Matroska.

Why? You don't want to playback your Speex files?
