Maybe Monty will make a video about it one day and we will all understand it. ;-) Silvia.

Oh, I will be very happy if I could see this video! Thank you very much Silvia.

Dear Experts, Can anybody please direct me to proper MDCT theory reference which will help me understand the code better? I'm trying to optimize MDCT for a embedded platform. So need good understanding about theory behind & implementation. Thanks in advance for your time. Warm Regards, Mahantesh -------------- next part -------------- An HTML attachment was scrubbed...

Dear list, Could you please tell me the values of the minimum and maximum cutoff frequencies for each coding version of the 44.1 kHz sampled data? For instance, are the values fmin=100 Hz and fmax=12 kHz valid? Thank you very much in advance. Kind regards, ? Fernando A.

I was waiting for Monty so summarize his ideas too, but from the irc discussion, it sounds like the extra

Hello. I am thinking of developing a tool for computer game makers, enabling them using an ogg file to hold a collection of very short context audio clips. I am looking for suggestion on usefulness of the tool once it is made, and its design. By "very short context audio" I mean the audio clips that usually is the response to a mouse-click or key press. e.g. a clicking sound, a

This patch should improve support for large files in liboggz and oggz-tools on Windows. I'm not hugely confident about this patch, since I'm not set up for actual testing under Windows, but I was at least able to resolve issues with merging large files under Wine. --Ben -------------- next part -------------- An HTML attachment was scrubbed...

Presuming that you are asking regarding the Ogg Vorbis audio format, the correct answer is: there is no minimum or maximum cutoff frequency. Vorbis can code all frequencies from DC to Nyquist. What Vorbis will actually do is extremely complex, extremely nonlinear, and highly dependent on bitrate. If you are in the mentality of linear time-invariant filters, you will never be able to understand

I'm not aware of an FPGA implementations yet. You could be the first! An encoder implementation would be much easier, because there are almost no rules about encoders. An encoder is free to behave any way it wants, so you could implement a very small subset of Opus and still have a compliant (and useful) encoder. A decoder implementation would be much harder, because decoders are required

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.
