DiskOut

DiskOut.ar(bufnum, channelsArray)

Record to a soundfile to disk. Uses a Buffer.

bufnum - the number of the buffer to write to (prepared with /b-write or Buffer.write) 

channelsArray - the Array of channels to write to the file.

s.boot; // start the server

(

// something to record

SynthDef("bubbles", {

var f, zout;

f = LFSaw.kr(0.4, 0, 24, LFSaw.kr([8,7.23], 0, 3, 80)).midicps; // glissando function

zout = CombN.ar(SinOsc.ar(f, 0, 0.04), 0.2, 0.2, 4); // echoing sine wave

Out.ar(0, zout);

}).send(s);

// this will record to the disk

SynthDef("help-Diskout", {arg bufnum;

DiskOut.ar(bufnum, In.ar(0,2));

}).send(s);

// this will play it back

SynthDef("help-Diskin-2chan", { arg bufnum = 0;

Out.ar(0, DiskIn.ar(2, bufnum));

}).send(s);

)

Object Style:

// start something to record

x = Synth.new("bubbles");

// allocate a disk i/o buffer

b= Buffer.alloc(s, 65536, 2);

// create an output file for this buffer, leave it open

b.write("recordings/diskouttest.aiff", "aiff", "int16", 0, 0, true);

// create the diskout node; making sure it comes after the source

d = Synth.tail(nil, "help-Diskout", ["bufnum", b.bufnum]);

// stop recording

d.free;

// stop the bubbles

x.free;

// close the buffer and the soundfile

b.close;

// free the buffer

b.free;

// play it back

(

x = Synth.basicNew("help-Diskin-2chan");

m = { arg buf; x.addToHeadMsg(nil, [\bufnum,buf.bufnum])};

b = Buffer.cueSoundFile(s,"recordings/diskouttest.aiff", 0, 2, completionMessage: m);

)

x.free; b.close; b.free; // cleanup

Messaging Style:

// The same thing done in Messaging Style (less overhead but without the convienence of objects)

// start something to record

s.sendMsg("/s_new", "bubbles", 2003, 1, 1);

// allocate a disk i/o buffer

s.sendMsg("/b_alloc", 0, 65536, 2); // Buffer number is 0

// create an output file for this buffer, leave it open

s.sendMsg("/b_write", 0, "recordings/diskouttest.aiff", "aiff", "int16", 0, 0, 1);

// create the diskout node

s.sendMsg("/s_new", "help-Diskout", 2004, 3, 2003, "bufnum", 0);

s.sendMsg("/n_free", 2004); // stop recording

s.sendMsg("/n_free", 2003); // stop the bubbles

s.sendMsg("/b_close", 0); // close the file.

s.sendMsg("/b_free", 0);
