	Hi, I would like to do the stretching (on the pitch and duration) of audio samples of a few seconds (wav file) in real time. Opcodes which do you recommend? thank you, enrico -- View this message in context: http://csound.1045644.n5.nabble.com/stretching-in-RT-tp5720930.html Sent from the Csound - General mailing list archive at Nabble.com.

	This is a ratio of the original frequencies in the input ihalfstep = 2^(1/12) kpitch = ihalfstep^ksteps where ksteps is the number of halfsteps of transposition you want (7 to go up a fifth, -7 to down a fifth, etc.) On Wed, Mar 13, 2013 at 2:16 AM, Enrico Francioni <francioni61021@libero.it> wrote: about: /kpitch - grain pitch scaling (1 = normal pitch, <1 lower,> 1 higher; negative backwards)/ in /mincer/ I do not remember which opcode conversion could be used for a tempered tuning system …any ideas? -- View this message in context: http://csound.1045644.n5.nabble.com/stretching-in-RT-tp5720930p5720975.html Sent from the Csound - General mailing list archive at Nabble.com.

	also, ksteps of 0.5 would give a quarter tone transposition, and that has the advantage of keeping the 12 steps to the octave familiarity On Wed, Mar 13, 2013 at 10:37 AM, Justin Smith <noisesmith@gmail.com> wrote: yes, exactly On Wed, Mar 13, 2013 at 10:34 AM, Enrico Francioni <francioni61021@libero.it> wrote: this is good to get the quarter-tone? /ihalfstep = 2^(1/24)/ -- View this message in context: http://csound.1045644.n5.nabble.com/stretching-in-RT-tp5720930p5720991.html Sent from the Csound - General mailing list archive at Nabble.com.
