Hey all - I have no connection to this app but I thought it might be of interest. I’ve been playing with “Moises” (Android and iOS) for about 20 mins now and it seems to have some promise.
It lets you upload (or share a URL) a song, which it splits into vocals, drums, bass and guitar/other. It lets you then isolate any of these tracks. Quality was varied - sometimes the bass was a bit low/murky or other tracks not quite right but generally pretty decent. The paid version also lets you change tempo and switch keys.
I’ve run some pretty average phone recordings of our lounge room jams through the basic AI mastering (as well as original versions of the songs we were covering as reference tracks) and the instrumental side sounds better. (Sadly there is no cure for my subpar vocals
iZotope uses the same underlying audio splitting code as Moises (specifically, deezer/spleeter) in Master Rebalance for both RX9 and Ozone, which are top tier audio recovery and mastering tools, respectively.
I use a plugin called Peel that works pretty well. It’s $34 atm on Plugin Boutique, plus you get uJam’s virtual drummer Beatmaker Phat 2 for free atm (it’s a set of playable drum loops).
Wow Moises does a terrible job trying to isolate Peter Hook basslines. I guess that would be expecting a lot though, the one I want to analyze doesn’t go below D2
Might try Peel or RipX to see if they have more controls.
Note that with RipX you can select one or a group of notes after the initial rip and manually assign them to a different stem if they aren’t in the right place.
Yep, it’s an ongoing problem I have with jazz, fusion etc. where the bass doesn’t stick to the lower notes, or where solos/melodies are being played on bass.
At least these are easier to sound out without splitting tracks. On second thought is that everyone’s experience or does that come from having played a melody instrument?
There are two main uses for these splitters: a) isolate the bass track to transcribe and learn that part; or b) isolate the bass track and remove it, such that you have a backing track for recording (or practicing).
I am purely interested in analysis and the reason I wanted it is that since melodic bass is often in a range overlapping other instruments it can sometimes be hard to track. In the song I am analyzing, when Hooky drops down in to the D2 range, his notes are hard to distinguish from the guitar, which is riffing in D minor.
