All, Just a heads up that the IETF codec working group has issued a last call on the draft Opus specification. This means we think the draft adequately documents the format, and that we're willing to live with whatever bugs are present in the reference implementation, if they can't be fixed without breaking decodes. In turn, this means we could really use some feedback from implementers.

...as to whether opus_multistream_encode creates a frame or a packet. The function summary says this: Encodes a multistream Opus *frame*. But later on it says: The length of the encoded *packet* (in bytes) on success or a negative > error code (see Error codes<http://www.opus-codec.org/docs/html_api-1.0.2/group__opus__errorcodes.html>) > on failure. I would appreciate clarification on this issue. :-) Thanks, William -------------- next part -------------- An HTML attachment was scrubbed...

...ers for voice/music. For example, for podcasts purposes, 16kbps, monoaural for voice and 64kbps, stereo for music, doing the switch over on the fly, frame by frame. I can see code for doing the voice/music detection, but it is not documented in the API documentation <http://opus-codec.org/docs/html_api-1.1.0/index.html>. Suggestions?.

Hi I am trying to use opus for encoding AES (spdif) stream . I suppose that input samples should be 16 bits in opus but samples in AES stream can be at most 24 bits. Can opus accepts samples more than 16 bits without any modifications in source codes ? If answer is No then "How can I modify opus to accept these 24 bits samples ?" Best Regards Kazem Baadpie -------------- next

I saw the custom API, but nothing explicitly says "CELT-only" just "custom sample rate and frame size". I'll dig further now that you've pointed me in a direction.

Hello All, This is my first appearance to the opus mailing list. My name is Michael Mehari and i am a researcher at Ghent University mainly on cognitive radio networking. Recently i am working on a demo scenario on self adjustable wireless audio conferencing and i selected opus for the audio encoding and decoding part. specifically the applications (i.e opusenc and opusdec) from opus-tools

Hi! Useful advice, thanks! Actually I had been using foobar2000 to recode, because it just makes it so easy to convert multiple files while keeping the metadata (I confess, I'm a "tagger"). But it's easy to miss some encoder option when being presented some default suggestions in a dialog form... Apart form that I always had the impression that Opus could be quite smart

...9;chunk' (where a chunk is 1 second of consecutive Opus frames, right now). Is this an unsupported use of the codec (and therefore a potential source of my issue), or should this have little impact on the output other than reduced efficiency? ta, dave [1] http://www.opus-codec.org/docs/html_api-1.0.2/group__opus__encoder.html#details -- http://david.holroyd.me.uk/
