changing TEMPO of ENTIRE song

yo what up fam

whats the esiest, quickest and most effective method of making an ENTIRE song FASTER/SLOWER.

i could simply up/down the BPM but then all my samples would be either too low or too high in tune. do i have to change the bpm and then work out what the equivelant TUNE change is for the BPM change i have implemented and then change the tune of ALL my samples to accomodate????????????????

surely there is a better way!!!!!???

cheers for any advice

This would be VERY tedious.

Some form of timestretch or pitch correction applied to the WHOLE SONG WAV, obviously that would be done on the PC, like in a wav editor or something.

but time stretching gives undesired effects when it is done to extreme

Then don't go to the extremes. You are talking about changing the wav as a WHOLE so your looking at choosing one of those 2 techniq's or both together.

You need a good timestretching program.
This is gonna cost you some $499 thou.

I've seen pros using Prosoniq Time Factory. It's perfect for speeding up a final mix it it's a little too slow/fast or has to fit into a given time, like tv commercials etc (u have to have your jingle excactly 30seconds when what you have is 34sec long... this will fix it )

Time Factory is program dedicated to perform high quality near-lossless time and pitch scaling on monophonic and polyphonic music signals. TimeFactory uses the latest advances in DSP technology to achieve time scaling amounts of up to one third of the original length, corresponding to a time stretching factor of 133% and more (or pitch scaling of up to 5 semitones) without audible loss in quality. This is as much as slowing down a complete music piece from 120 BPM to 90 BPM, or vice-versa.

I have never used it myself, but i have seen and heard it in action.
Once a friend speeded up a whole 32 multitrack track song by speeding up each individual track one by one. It was amazing... No audible loss in sound quality...

I got excited myself so... heres some more info for you:

Dont use time-based samples like drum loops and riffs - instead use individually sequenced notes using multisamples and sound modules - that way you can adjust the tempo of your track without worrying about timestretching, you'll also be able to change the tempo quite dramatically.
