Easy Sound Editing Question

category: residue [glöplog]
Hello.

With what program is it possible to double the length of a sample? (Or more general, multiply its length with a factor. Something like stretching an image.)

Adok: maybe it would be easier to ask Google...

I always use the NeoConzimizer plugin for all of my argument stretching needs.

Puryx: true, but still Adok's thread is way more ontopic than all the other random crap here :-)

spacus: sure, but that was not my point :)

... or play it to a two times lower freq, it will magically length twice the time. (?)

and else, audacity.

Audacity is a good choice for audio-editing since it is open-source and has many functions.
(The noise filter thing for example works like magic!)

I don't remember if Audacity supports FFT time-stretching :\
For listening purposes: http://www.xs4all.nl/~mp2004/bp/ seems nice

For editing try the link section here: http://en.wikipedia.org/wiki/Audio_timescale-pitch_modification

There are also some free VST around.

Thanks for your tips! I am pretty surprised it apparently isn't possible to modify the "note-length" in a tracker, or have I missed something?

What a strange logic :)

Well, open source software helps you learn how to do it yourself if you're a coder :)
added on the 2008-06-01 19:05:24 by Adok Adok
first off, do you want to preserve the pitch or tempo?
added on the 2008-06-01 19:13:48 by Gargaj Gargaj
Well, I wasn't asking for a preservation of pitch and tempo, but in fact that's what I ultimately want. I want the sample to sound longer.

adobe audition
goldwave
soundforge
audacity
...

if you want to preserve both pitch and tempo, you're ultimately doing nothing to the sample.

But how can I make a sample sound longer?

with "time stretching"
1) mount a speaker system
2) play the sample while at the same time -
3) throw a recording device originating from the speaker at half the speed of sound
4) win.

hmm, i also recall some jmax patches that did fft based time stretching quite well, they mightve even been some of the examples which are downloadable from ircam. cant remember that well, it's over 5 years since i used that software.

adok: your question is ambiguous.

This thread is hillarious.
