The original sound is the fourth movement of the ninth symphony of Beethoven (length: 28'57").

For those who don't know it... here is an extract of the original (the beginning):

Using AudioSculpt for people in a hurry:

Resulting sound:

If we are even more hurried... : using the command line generated by AudioSculpt:

Resulting sound :

The first sound is obtained using a compression coefficient of 0.01. The sound is 100 times faster.

This coefficient is available directly in AudioSculpt's interface.

The second sound is obtained using compression coefficient of 0.001. The sound is 1000 times faster.

This coefficient is not available directly in AudioSculpt's interface.

To degrade the sound quality as little as possible, it is recommended to avoid passing through SuperVP multiple times.

Explanation:

We start the compression treatment in AudioSculpt with the desired parameters, but with a random coefficient.

We stop the calculation early: we are just interested in the command line and the temporary file.

We edit the temporary file with the new value and we start the command line again (duplicated before)

#Remark :

We can notice that the waveforms of the original sound and the 17.6 seconds sound are very similar.

The wave form of the 1.76 seconds sound obviously presents a lack of accuracy...

# General remark :

The latest version of AudioSculpt allow a compression of 0.001.

Nevertheless, this example show that one can go beyond this limit by using temporary files, assuming that SuperVP will accept them !
