[PD] rockafella time-stretcher

[Patrice Colet]

 I've turned the B14.rockafella audio example into an abstraction where [phasor~] has been replaced by a [line~]
for triggering the sample reading, the abstraction and a test patch is attached.

 Once the soundfile has been loaded into a table we just need to set the original tempo of the soundfile,
and the tempo at which we want the soundfile to be played.

 If we want the soundfile to be played in loop mode, we just have to trig again when the sample reading is over, by using [del] for example,
or [qlist].

 The stretch works good but something very strange is happening, let me try to explain,

when the read point reaches the middle of the soundfile a noise is appearing,
and I couldn't determine why, it sounds like a buffer overflow, or a little distortion.
this is happening when both tempo have the same amount.

 Maybe the method for reading a soundfile is different when using [line~]?

I wouldn't like to use the vocoder method because it takes a lot of cpu and artifacts comes whenever the sound is stretched or not.
