library for creating Opus files?
...lly on my x86_64 Ubuntu Trusty 14.04 box. I was just able to do $ sudo apt-get install opus-tools $ opusenc music_48kbps.wav music_48kbps.opus I remember also being able to compile opus-tools (git://git.xiph.org/opus-tools.git) some time ago.

library for creating Opus files?
Which one of the various libraries on xiph.org allow me to create an Opus file? The 3 or so libraries on the Opus download page all seem to be for reading files, converting and/or encode/decode streams. I have device that outputs a stream of Opus 'frames' and I need to save them into an Opus file. -- Tony -------------- next part -------------- An HTML attachment was scrubbed... URL:

...nk__ this is the only library, or sample code, that shows how to create audio file containing Opus. Too bad there isn't a simplified wrapper for file CREATION like libopusfile does reading. If anyone knows of one, I'd appreciate the information.

Typically end-to-end 'delay' of live audio
I have an audio device driver for a live feed that produces Opus frames, if I were to use icecast, what sort of real-time delay can I expect? 3-5s? 5-10s? more? I've tried using the html5 <audio> tag directly to stream my source, but it seems browsers like to queue-up 250K to 500K of audio 'data' before they begin playback. That introduces a 15-30s delay depending on browser

Not yet. We have thought about going to flash in hopes it would provide less latency, but I haven't looked into it yet. Though, technically, flash is a plugin, but it seems to have earned "special status" by the browser developers.

Questions regarding OPUS_APPLICATION_AUDIO vs OPUS_BANDWIDTH_NARROWBAND
I have an audio device whose 'driver' gives me Opus encoded frames using OPUS_APPLICATION_AUDIO and max bandwidth set to OPUS_BANDWIDTH_NARROWBAND. How does Opus encoder decide the center point of the 4K bandpass filter? Is it done frame by frame? -- Tony -------------- next part -------------- An HTML attachment was scrubbed... URL:

Thanks. Here's bit more detail. We have a scientific audio instrument that comes with its own audio driver. This driver gives us Opus 'frames'. From a remote location (typically less than 200mS round trip) we would like someone using a browser (without a plugin) to 'hear' this device. We need the low end-to-end delay as there is an active Video session (separate
