hi,<br> <br> I have a small and quick question. <br> When speex divide the UWB speech signal into High and low bands, JMV said to me in HA that :<br> "For ultra-wideband (0-16 kHz, 32 kHz sampling), I first split the band into wideband (0-8 kHz) and "very high band" (8-16 kHz). Then, the wideband itself is split into low (0-4 kHz) and high (4-8 kHz) band. So there's a total of 3 bands encoded separately. In practice the very high band (8-16 kHz) has only the rough shape of its spectrum encoded with 1.8 kbps."<br> <br> Now the question is if a signal which is not sampled at 8, 16 or 32KHz but at some other sampling rate, say 44100Hz(as speex supports upto 48KHz and it in general gives good quality for 44100 Hz too), how speex divide it into the sub-bands ??<br> <br> I understand that it take it encode it as a UWB mode but its very foggy to me about how it interpret this 44.1KHz signal ?? How it does sub-band filtering for this??<br> <br> kindly reply
asap. <br> ----<br> dev<BR><BR>***************************************************************************<br>Devi Lal Sharma<br>Final Yr.
