Time streching vocals to fit the song's tempo

Im currently looking for a good quality method to slow down or speed up vocals without to much quality loss or that it sounds for example robotic or weird.
Currently i need to speed down vocals from around 179 bpm to around 140 but whats a good programme to do it with?

Ive tried Adobe audition , but that didnt gave me the right result ,
Its just not on tempo all the time.

Anyone got any tips?

Try to make the length of the sample 140/179 times of what it was. Else you should use cool edit pro 2 or so? Should work. (?)

slowing down vocals for about 20% will produce some unwanted artifacts for sure - it will definitely not sound natural. you can use any wave editor (wavelab, soundforge, cooledit/audition) or you can do it in your sequencer. cubase sx has a great timestretch feature.

Correct.

Fruity hasn't. Just for the record.

for time streching vocal in fruity I usually use the fruity granulizer. works really well for me.

Use the typical analog method as much as you can without going too high or low in pitch, then use the digital stretch method. If you're willing to have it go up/down a few steps then I'd definitely do the analog-style shift first, gives you less chance for artifacts at the end.

as a matter of fact, it does. and it is not a destructive one like the one in cubase.
load a sample in the sample channel (however try to get it properly cut so that is sounds ok when looped) and when you open a channel just above the waveform display is the 'Fit' box which allows you to stretch that sample to fit a number of steps. for instance, if you set it to 16, then the sample will stretch to play for 16 16ths or one bar. trust me on this, i just downloaded a 2mb pdf archive from fruityloops.com just to get that info!

in Sound Forge you can use Process -> Time Stretch

for the percentage calculate:
original bpm / destination bpm x 100% = xx.xx%

this works good if the bpm change isnt too big. stretching from 179bpm right down to 140bpm will no doubt give you serious artifacts...

Does anyone know if GOLDWAVE will do this?

Thanks for the great replys! im going to try it out now

with special programs:
179 -> 140 = not perfect result!
179 -> 172 = better!

BTW, have you thought -> generate REX file or slice the vocal part manually and try to fit it to 140BPM tempo. You just decrease the "space" parts It's not working with any vocals but TRY this method too!

I tested long time ago PROSONIC TIMESTRETCH. Results were OK. About the program price, don't know Google it
