What got me experimenting with Opus is that I heard it's going to be a supported codec in WebM, which I also have a Premiere plug-in for: http://github.com/fnordware/AdobeWebM I just posted a new beta that includes Opus support. Naturally, I *think* I'm doing it right, but I'd love for someone more knowledgeable about Opus or WebM to take a look. The closest thing to a standards

Yes, it's basically an intrinsic aspect of the mathematics. If you seek into the middle of an Opus stream, that's about how long it takes before the audio converges to be correct.

Hey everyone, I've written a FLAC plug-ing for Adobe Premiere. It's actually part of the Ogg Vorbis plug-in I originally set out to write. You can see it here on GitHub: https://github.com/fnordware/AdobeOgg I just finished the first beta a few hours ago. You can download binary plug-ins from here: http://www.fnordware.com/downloads/Ogg_v0.5b1_mac.zip

Hey everyone, I've added Ogg Opus support to my Adobe Premiere plug-in here: http://github.com/fnordware/AdobeOgg Now I'll add Opus support to me WebM plug-in too. I've got this Opus stuff mostly figured out, but I have a few questions. Here's one: What do the numbers in mapping mean? I see that opus.h refers to the Vorbis channel mapping order, so does mapping in Opus take

Hey everyone, I've come to appeal to the FLAC gods again. I have a plug-in for Adobe Premiere that adds support for Ogg Vorbis, Opus, and hopefully FLAC. But I can't get FLAC to link on Windows for some reason. I had to add x64 targets to the .vcproj files that ship with FLAC, so perhaps something went wrong there. Then I tried making new projects from scratch and importing the FLAC

The intent was not to allow gaps in the file like this (that would confuse the

Unfortunately, I don't think that's it. Visual Studio gives me a specific error when it can't find a certain library file. I think these are the errors you get when a

Hey everyone, according to Wikipedia's 4-year-old information, there is no standard for putting metadata into an Ogg file. That metadata must be included in the codec. For example, what if I want to make a Theora movie and include information about the color space or embed an ICC profile? Or can I include general textual information, like copyright? What about timecode? Brendan

I get reliable crashes if I create a 6-channel encoder using opus_multistream_surround_encoder_create(). If I use opus_multistream_encoder_create() instead and pass in the same parameters that opus_multistream_surround_encoder_create() sends out (streams = 4, coupled_streams = 2, mapping = {0, 4, 1, 2, 3, 5}) I don't get the crashes. I notice that opus_demo.c uses

Whoops, I meant for the total duration of the file you should be able to have your vorbis length match the file duration length exactly. As my next paragraph said, in general I think the Vorbis packets will never align

Hey everyone, I'm new to the world of audio, so can you please drop some very basic audio knowledge on me? What's the correct way to convert from float audio samples to integer ones like FLAC uses? If I'm converting to 8-bit, that has a range of -128 to 127, right? Do I multiply my float input by 127 or 128? Brendan

It does not; Vorbis needs only lap consecutive frames, and the timing was constructed so that the 'timestamp' of a vorbis frame actually points to the middle of the frame data. When you combine a starting frame with the subsequent frame, the data you get back is from the starting timestamp forward. Because Opus needs to preroll a larger amount, that trick wouldn't work with Opus.

True. > That metadata must be > included in the codec. More generally, in a stream in the Ogg file. Codecs are streams, but so are things like Ogg Skeleton. Information about Metadata has been collected together in the Xiph Wiki

In the Opus API (which is different from Speex), the range of float PCM values is +/-1. For the integer API, it's +/- 32768.
