I tried cross-synthesis with a harmonic
signal, which is ok, but<br>> what I’m actually trying to do is to “tune” a field recording, in a way,<br>> so it can have harmonic relations to a live instrument.<br>> <br>> I played with the pvtune~ object from fftease which is nice, but the<br>> results end up sounding a bit autotune-ish. And I also tried driving a few<br>> vcf~ filters with frequencies running from fiddle~/sigmund~ but the<br>> fundamental from these objects is too erratic and it sounds very<br>> unnatural.<br>> <br>> Wishart describes in his book a technique he calls spectral focusing,<br>> which relies on lpc. He says that lpc can be set to generate a filter bank<br>> which is distributed evenly with respect to pitch, but I’m not sure I<br>> understand what he means and how it can be done in PD. lpc seems to output<br>> a set of amplitudes for the coefficients. Can I set the filters to<br>> frequencies of my choice?<br>>
<br>> Any help with this would be greatly appreciated,<br>> Zax<br>> <br>> <br>> <br>> _______________________________________________<br>> <a ymailto="mailto:Pd-list@iem.at" href="mailto:Pd-list@iem.at">Pd-list@iem.at</a> mailing list<br>> UNSUBSCRIBE and account-management -> <a href="http://lists.puredata.info/listinfo/pd-list" target="_blank">http://lists.puredata.info/listinfo/pd-list</a><br><br>_______________________________________________<br><a ymailto="mailto:Pd-list@iem.at" href="mailto:Pd-list@iem.at">Pd-list@iem.at</a> mailing list<br>UNSUBSCRIBE and account-management -> <a href="http://lists.puredata.info/listinfo/pd-list" target="_blank">http://lists.puredata.info/listinfo/pd-list</a><br><br><br></div></div></div></body></html>
