Hi, another question on that one: Are there any restrictions for the length of a signal vector? Does it have to be even or is there any maximum length?
1.) it has to be a power of two there *was* a restriction of the length too (i think 65536 samples), but this has changed to 2^32 (which is more than 27h at 44.1kHz)
2.) regarding up/downsampling: funny enough, just today i noticed a bug bug within the setting of the sample-rate when doing up/downsampling: the sampling-rate is modified the wrong way: if you do upsampling by 2 from 44.1kHz, a sampling-rate of 22.05kHz is reported. the bug is in line 889 of d_ugen.c: diff says:
889c889 < srate = parent_srate * realoverlap * upsample / downsample; /* IOhannes
*/
srate = parent_srate * realoverlap * downsample / upsample; /*
IOhannes */
mea culpa
