Finally i found out how to perform BPM correction on android. :-) Problem could be fixed in few minutes, but i didnt noticed that i have that app. I never thought Audio Evolution have this fantastic time stretch option. I bought it few months ago and i was like: hm, okay. This app is just for synchronisation. Other options? Naaaah.
Anyway, you should have this few things.
1. Paper and pencil
2. Basic knowledge about math
3. Acapella and original version of song
4. Audio Evolution Mobile latest version.
1. Check on internet what is BPM of song you want remix. It is 128BPM for example. Okay, and for example you wanna make dubstep remix which BPM is 140. Get your paper and start calculation.
2. You need to know rules of proportion. If 128 BPM is full speed, lets just say 100% of speed, 140BPM is how many % ????
Correct answer is 109.375%
So? What is that mean? That mean you need to speed up audio for 9.375%
3. Go to Audio Evolution Mobile and import both (acapella and original) , set tempo on 128. Turn on Grid option, just to see where bars are. Now manipulate with original version of song. Move it through grid bars and make beat fits perfect with bars. Now synchronise acapella with original sound. Until you dont hear one perfect sync voice from 2 sources. Now you have acapella syncronised with the beat and bars. PS....You can import some drum patterns besides metronome sound. To have better view about sync. Now you are ready for final step.
4. Long press on audio track and choose offline fx or something like that (i still cant believe i didnt noticed these options). :)
You will see option time stretch. Click on it.
There is some value. Like 1.0 That means there is no change in time. If you want to speed up tempo you should make 100% minus 9.375 which is 90.625% In this case you should enter new value. Not 1.0 anymore, now is 0,90625
Click on apply and wait. Now is time of audio compresed and tempo is faster for 9.375% which is 140BPM
Hope this can help to you. ;-). I made correction from 91.1 to 91
A lot of numbers in % but it works.
Hmmm......
Shameless self promotion.

AZ, I got 3 words for you on this track ^^^^^
I like this, perfect title match, I got a little bit of digital time travel effect, distorting from modern tech to early 70's tech......
Well done.
Well this is shameless nice. :-)
Check out my new track.

Works exactly the same way. 3.2 caustic is en route which doesn't require math at all. Just the common sense method of start key/bpm and end one. Job done

The shameless plug is pretty catchy
I was a little curious about using Akaizer for time stretching in Android, it has a command line interface for Linux. Anyone have experience with running command line tools on their Android device?
Can't wait for Caustic 3.2, it's my favorite music application right now, and I own both Ableton 9 and Reason 7. :D

How does one sync a sound with the metronome?
I am using Robot Song with 8 bit synth and it doesnt sync with the metronome?
I don't trust the internets; I trust my ears. The internets didn't help me when I searched for the tempo of Iron Maiden's "The Trooper". (I found at least two different "correct" tempi, both of them wrong. It's why the vocals don't really sync up with the beat in my remix)
Listening to the song, I turn on the metronome in Caustic or on my Yamaha keyboard, and then use the "tap tempo" feature to get close. Then I fine-tune until the metronome is clicking in perfect time with the source track.
This is not exactly clear as you put it. I would have given the formula a/b(100) where a is the tempo you want the track to be, and b is the original tempo of the track. So 140 / 128 = 1.09375; multiply that by 100 and you get 109.375.
Audacity does the same thing, if you have a PC. It's what I used before I started with REAPER.
desktop programs also can directly tell you what bpm the track is in.

Thanks everybody - but Robot Song is a sound on Caustics 8 Bit Synth. Or maybe it's from one of the EIP Packs - i cant remember, but that particular sound, (there may be more) ( im sure there are) has its own tempo - how do u sync a long-ish sound with the metronome?
Plzzzzzzzz?
When you said math i lost interest
