Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
Top quality stretch and pitch for use in Blocswave
It took me a while to finally realize this obvious solution, so maybe some others also don’t realize it.
I have pitch n time from serato sample on my Mac but I never use that. So I always wanted that on iOS of course. But for my purposes it’s easy enough to get the same quality results (to my ear) by simply using DJay Pro. Just do the stretching before you go to Blocs and it’s pretty fast work.
First make sure you turn off auto gain and audio limiter off in the mixer settings. And change recording to WAV.
Since we use Blocs to chop after, it’s fast enough to simply listen to your song you want to sample in djay (after exporting from YouTube in beat time), here you get the bpm and key. Then change them as you see fit and go back to the start of the song and hit record. Listen to the song then export.
The limitation is 20% stretching but I think that’s ok for the most part. Even if we had serato sample I don’t know that it would be a better workflow because blocs wave is pretty hard to beat in that regard. It’s just the time stretching isn’t as good. You can clip launch from anywhere, it’s the sampling itself that is so nice in Blocs.
