Service (or program) slowing down music

Question

Audio

Good afternoon everyone.
Once here on Habré there was an article about a service (program?), You upload music there, and in response you get a sound that is slowed down by the Nth number of times.
I even have one file from that topic preserved, but I can’t find the service (prog) itself.
Maybe someone will tell?

Answer 1

VLC can sort of change the speed

Answer 2

Audacity 1.3 Beta (Unicode). Effect -> Change Speed…

Answer 3

I believe this is Paul's Extreme Sound Stretch
program hypermammut.sourceforge.net/paulstretch/

Answer 4

AIMP. In the effects manager, adjust the "speed".

Answer 5

I recommend Adobe Audition 3, a powerful audio editor.
You can change the speed and tone.
You can both mix sounds relatively simply and apply effects.
The interface is quite friendly, unlike some others.

Answer 6

Thank you, I’m chasing programs :)
All the same, at that time on Habré they wrote about some site where you upload the file, and in response it was the same, but slowed down by 10-50-100 times, it seemed like you could still choose to slow down ...

Answer 7

The music (paid) program Ableton Live can do this. But. It should be taken into account that firstly, there are 2 ways of "slowing down": with the preservation of the pitch (pitch) and without. For the first and second there are different algorithms, and they all lead to distortions and artifacts.
For example, to slow down while maintaining pitch, you can beat the sound into samples and play them several times, you can play several times with a change in direction, you can beat the sound at random or by transients, you can use DCT and recalculate the sound according to its spectrum.
Therefore, the result will most likely not be very impressive - just read the description of these algorithms to understand that they will not give anything good at the output.
