Play a sound file
create a buffer
~mysound = Buffer.read(s, "path/to/sound/file.wav");
simple play
{PlayBuf.ar(1, ~mysound)}.play; // number of channels and buffer
get sound file info
[~mysound.bufnum, ~mysound.numChannels, ~mysound.path, ~mysound.numFrames];
varying speed
{PlayBuf.ar(1, ~mysound, 2, loop: 1)}.play; // play 2x faster {PlayBuf.ar(1, ~mysound, 0.5, loop: 1)}.play; // play at half the speed {PlayBuf.ar(1, ~mysound, Line.kr(0.5, 2, 10), loop: 1)}.play; // playback speed goes from 0.5 to 2 in 10 seconds
changing direction
{PlayBuf.ar(1, ~mysound, -1, loop: 1)}.play; // reverse sound {PlayBuf.ar(1, ~mysound, -0.5, loop: 1)}.play; // play at half the speed AND reversed
Play a MIDI file
Do this and that.
List Operations
scramble
reverse
find nth
Looping
While
(
i = 0;
while ( { i < 5 }, { i = i + 1; "boing".postln });
)
For
for (3, 7, { arg i; i.postln }); // prints values 3 through 7
ForBy
forBy (0, 8, 2, { arg i; i.postln }); // prints values 0 through 8 by 2's
Do
[ "first", "second", "third", 444) ].do({ arg item, i; [i, item].postln; });
5.do({ arg item; item.postln }); // iterates from zero to four
"you".do({ arg item; item.postln }); // a String is a collection of characters
'they'.do({ arg item; item.postln }); // a Symbol is a singular item
(8..20).do({ arg item; item.postln }); // iterates from eight to twenty
(8,10..20).do({ arg item; item.postln }); // iterates from eight to twenty, with stepsize two
