在SuperCollider中，把声音渲染成文件的最佳方式是什么?

Question

以编程方式将SuperCollider程序渲染到文件(例如wav文件)的最佳方式是什么?

我可以指定文件的持续时间(例如30秒)吗?

Answer 1

您可以对Score.recordNRT执行此操作。

这里有一个关于如何使用它的教程

Answer 2

除了Score.recordNRT之外，还有许多不同的方法可以做到这一点(这可能是更方便的方法之一，也是我不知道的事情)。DiskOut.ar取path和channelsArray为args。您还可以尝试Server具有的.record实例方法。下面是两个例子(来自帮助文档):

DiskOut.ar方式

// 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("~/diskouttest.aiff".standardizePath, "aiff", "int16", 0, 0, true);
// create the diskout node; making sure it comes after the source
d = Synth.tail(nil, "help-Diskout", ["bufnum", b]);
// 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])};
b = Buffer.cueSoundFile(s,"~/diskouttest.aiff".standardizePath, 0, 2, completionMessage: m);
)
x.free; b.close; b.free; // cleanup

Server.record方式:

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);
}).add;
SynthDef("tpulse", { arg out=0,freq=700,sawFreq=440.0;
    Out.ar(out, SyncSaw.ar(freq,  sawFreq,0.1) )
}).add;
)
x = Synth.new("bubbles");
s.prepareForRecord; // you have to call this first
s.record;
s.pauseRecording; // pausable
s.record // start again
s.stopRecording; // this closes the file and deallocates the buffer recording node, etc.
x.free; // stop the synths
// look in your recordings folder and you'll find a file named for this date and time
