...requencies above 20k are effectively not encoded. I've been trying to get up to speed on the specification, and studying its operation, but as far as I can infer, there is a fixed set of 21 bands distributed logarithmically to encode DC to 20k. If I were inclined to encode at say, 96k, and pass ultrasonics up to 40k, I suppose I could in theory lie to the encoder about its input rate so it thinks it's 48k, and I could restore its 96k rate after decoding, but obviously this would result in doubling the necessary bit rate. Is there a more efficient way to encode information over 20k without breaki...

That article is a bit too dismissive. I agree that one cannot hear the difference between 48KHz/16bit and 192KHz/24bit if you just transfer the data directly to the audio output device. As such, there is no good reason for Opus to support higher than 48KHz (especially since this is lossy compression, anyway). However, in general, that's not all you do with audio data. 192KHz is useful for

I am new to R and what to find out which package would be best to create a surface plot, 2d or 3d if possible. I have a matrix (depth.dat) which has over 15k depth measurements from an ultrasonic corrosion mapping application. These depth measurements only have one axis (x) but I have used Octave and gnuplot providing decent results, but R seems to have a web interface with PERL which is what I am looking for.

Hi, I've been looking for Image Processing packages. Thresholding, Edge Filters, Dct, Segmentation, Restoration. I'm aware, that Octave, Matlab etc. would be a good address but then I'm missing the "statistical power" of R. Does anybody know of packages, projects etc. Comments on wether the use of R for such matters is useful are welcome. Greetings Thomas Kaliwe
