I want to classify bipolar neurons in human cochleas and have data of the following structure: Vol_Nuc Vol_Soma 1 186.23 731.96 2 204.58 4370.96 3 539.98 7344.86 4 477.71 6939.28 5 421.22 5588.53 6 276.61 1017.05 7 392.28 6392.32 8 424.43 6190.13 9 256.41 3850.51 10 249.17 3118.14 11 276.97 3037.29 12 295.30 3703.7...

...ations would be related to MP3 being bad than > anything else. One obvious problem at the lowest end is its filter bank. It simply hasn't the resolution to model what's happening at the lowest of the low end, perceptually speaking. After all at LF we get the heavy attenuation of the cochlea, combined with *extremely* compressed pitch sensitivity. No sane MDCT-based coder allocates many bits there, and LPC-based ones can often do even better because of the pitch sensitivity side of things. > Most signals have more LF energy than HF, so it's normal for the noise > to look...

...e structure of Eberhard Zwicker's "Analogmodell". That model consists of analog electrical elements. ftp://ftp.tnt.uni-hannover.de/pub/papers/2000/Diss-FB.pdf Input: Raw 100KHz monoural 16bit audio Output: hair cell excitation signal at 251 equidistant locations in the cochlea at 10KHz. Anyone have a copy of sox safely hacked to resample to 100KHz? I removed the check, but I'm worried about internal overflow conditions. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a m...

Hi guys, as MP3 and Opus have very similar objectives, I think the original poster's question was a valid one: Why does Opus have more artefacts in the lower frequency ranges than MP3 has? The spontaneous suspect that lower frequency artefacts may be more noticeably than higher frequency artefacts seems plausible, also. Is it a matter of energy (which is higher for higher frequencies)?
