[sc-users] Time Strech/Compress with SuperCollider

[PyoungRyang Ko <pyoungryang.ko@xxxxxxxxxxxxxx>]

Dear advanced Users,

How can be a sound file produced by Time Strech/Compress in SC3?

E.g. I have a sine wave 440 hz with 10 second as a source.
I want to produce a new processed sound file from this source without pitch
alteration but 11 second.

I want to have many files produced in this way:

Source duration 10 Sec.

Processed file 1: 9.995 Sec.  // 10 - (1 * 0.001 * 5)

Processed file 2: 9.990 Sec.  // 10 - (2 * 0.001 * 5)

Processed file 3: 9.985 Sec.  // 10 - (3 * 0.001 * 5)

Processed file 4: 9.975 Sec.  // 10 - (5 * 0.001 * 5)

Processed file 5: 9.03 Sec.  // 10 - (7 * 0.001 * 5)

And so on

The function for this series is not hard to formulate.
 
I don't know how to however combine the formula for
time-stretching/compressing.

I want to get the result as clean as possible.
That mean, if I use a sine wave, then the result should not contain so many
other frequencies, furthermore NO GRANULATION of the sounds.

Is it possible with SC?

If not possible, I must waste so much time in Pro tools for each sound
file.....

Sincerely yours,
Your non-advanced SC neophyte
