I have a track that I am working with and I need to increase the BPM by 2 BPM (which is roughly 1.49%) and I was wondering if this is going to affect the bassline as far as being out of key or having the same punch since I'm pitching it up a bit?

Also what program would you say has the better algorithm to keep the song sounding as close as possible to the original? Serato Scratch Live or Audacity for Mac OS?

I keep A/Bing them and for some reason it just seems like the bass is a little heavier when it's at the original tempo as opposed to the 2 BPM increase...maybe I'm just crazy? lol


What do you guys think? Is 2 BPMs enough to take away some impact from the bassline or should it still be hitting the same key and with the same PUNCH?

Ableton will accomplish this best of any daw i think.

Hard to tell because i don't know if you'reworking with audio or midi. I'm assuming audio? but your questions are a little strange from either end no offense

If its MIDI, when you increase the BPM the notes will be shorten but you will not notice a difference in the sound.
If its audio, your DAW will compensate by timestretching the audio sample. There are different time stretch settings, Sometimes you might notice pitch shifting and graininess, I would advise setting to complex pro if you notice this.

If he was working on MIDI it wouldn't be a problem. He's working audio, and by moving the BPM up he's reducing the lengh of the audio clips, therefore pitching them up a bit.

What you could do is
- sample just the bass hit
- find someone (friend or anything)
- get him/her to play randomly one of the 2 samples (original or modified) several times (not the same everytime, randomly ofc) and to note down what he/she played
- you, by ear, try to guess which one of the 2, note your results
- compare, see if it made that a difference
- ???
- profit

If its audio, In ableton change your time stretch settings

Yes I'm working with audio

you can do in audacity, with out affecting the pitch. Audacity > Effect > Change Tempo.
2 bpm wouldnt make a difference anyway

what i wanna know is why it needs to be 2bpm faster lol, why does the tempo matter? lol

also it wont be out of key as everything will be pitched up with it so everything will match

but yeah, why does it need to be 2bpm faster, i can understand that it may sound better at a different tempo, but you have already said that it doesnt and you prefer the original, thats why this question has arisen.

It's hard to explain...I'm just basically interested in the best way to adjust the tempo by 2 and keep the track sounding as close to what I originally started with. I can't redo the track because some parts were live but I just want the track to be a little faster. So basically what I'm gonna do is convert it to an WAV and throw it on my Serato and then just play it faster or I might do Ableton. Thanks for the suggestions!

cant you just like, pitch it up, with, you know, the turntable/cdj or whatever when mixing? and like beatmatch it maybe

It's kind of odd the amount of people who are kind of perplexed by this question...

Very simple:
If you increase the speed, does the pitch change? Yes.

Sound is just waves. Pitch is measured in the number of cycles per second (Hertz), or how many times a wave goes from a peak (/\), to a trough (\/), and back to where it started. By increasing the speed, you increase the speed in which a wave will cycle, and your pitch will increase.

Think about vinyl: You beatmatch by adjusting the pitch fader, and by increasing the pitch fader you make it faster and higher pitched at the same time. You should get to know your daw, and what sort of timestretching features/algorithms it has, because there are ways to stretch audio with pitch lock (which should only be used for small adjustments).

Sorry for the confusion...

I was trying to find out if changing the tempo by 2 BPMs is going to change the key of the song and from researching this a bit I found that as long as the pitch adjustment of a song is not more than 3% (which 2 BPMs equals out to about 1.49%) then the song should stay in the same key.

So I can speed my track up by 1.49% and I shouldn't have to use any timestretching or pitch adjustment tools because adjusting it by that amount shouldn't affect the key it's in.

well, it will, any change of tempo will slightly change the notes, it wont be a whole note higher but it will still be slightly differnet, its not like it doesnt change until getting yo 3% and then just jumps up a note

what in the fuck

point will be that it's barely noticeable though
