LPCIN


LPCIN works pretty much the same as LPCPLAY, except that it allows you to read an input sound into the LPC analysis filters. Many of the additional commands are indeed the same as LPCPLAY, so please refer to that document for information.

The main LPCIN command has the following p-fields: 

LPCIN(p[0]=outskip, p[1]=inskip, p[2]=duration, p[3]=amp, p[4]=frame1, p[5]=frame2, [ p[6]=warp)
And here is a sample score: 
/************   LPCIN.data *****************/

/* p0=start,p1=inskip,p2=dur,p4=amp,p5=frame1,p6=frame2[,p7=warp] */

rtsetparams(44100, 1, 256);
load("LPCPLAY");
bus_config("LPCIN", "in 0", "out 0");

rtinput("guitar.wav");

float thresh,frame1,frame2,warp,start,amp

frames = dataset("spoken.lpc",0)

/* none of this is currently used by LPCIN, but might be */

/* p0=threshold,p1=randamp,p2=unvoiced_at_norm_rate,p3=risetime,p4=decaytime,p5=gain_threshold */
lpcstuff(thresh = .01,  randamp = .1, 0,        0.1,0.5,0)
set_thresh(0.001, 0.1);

frame1=0
frame2=frames-1
warp=0
amp=0.3

LPCIN(start=0,inskip=0, DUR(0), amp, frame1,frame2,warp);
