Extract Jazz Bass from Music

February 27, 2007 | 3:28 am

Hello ,

I am a 20 years fan of fusion bass guitarist Jaco Pastorius and I want to
extract and record his 1962 Fender Fretless Jazz Bass from the crowded
records.

I read somewhere about STFT and spectrum peaks. I am not a scientist and I
do not know how to do it but if I am not wrong , it is possible to play with
these dirty records spectrums like an winamp EQ for to remove unwanted noise
.

Is above written solution real or is there a better way ?

Best ,

James Beauchamp is doing that here at University of Illinois. He’s
doing a great job, but he’s not having the easiest time with it. You
might look into his research.

As a ready to use programme AudioSculpt
(http://forumnet.ircam.fr/349.html?&L=1) is great for this since you
can visually see the spectral information and delete what you don’t
want (only available in the latest version). It also offers transient
detection (and places markers on your attack points). It has a noise
reduction function (also present in csound for free but without the
visuals! http://www.csounds.com) which takes a portion of a sound file as
"noise" and attempts to extract it from the original.

Waves Xnoise plugin is also great for dynamic noise reduction but very
very expensive!

I like SPEAR quite a bit for doing this kind of work:

http://klingbeil.com/spear/

also, the ‘extraction’ of musical style was done via a totally
confused and ad-hoc basis (i.e. I listened and changed my lisp
code), but these were early experiments in trying to imitate
different performance traditions:

http://music.columbia.edu/~brad/writing/papes/blues-o-matic.pdf

http://music.columbia.edu/~brad/writing/papes/Sense_of_Style.pdf

The pdfs for the first two are kind of bad scans, here are links to
plain text:

http://music.columbia.edu/~brad/writing/papes/performance_model.html

http://music.columbia.edu/~brad/writing/papes/blues-o-matic.html

We’ve also done some of this in my grad seminar:

hope this is enjoyable!

What the heck, might as well dump this all out there.

Here’s where to find the code that did the performance modeling:

http://music.columbia.edu/~brad/software/index.html

look for "piece-o-matic" and "riff-o-matic".

And a couple of pieces realized with this code:

http://music.columbia.edu/~brad/music/#Rough_Raga_Riffs

http://music.columbia.edu/~brad/music/#Almost_Real

(you might have to hit twice to get to the link)

This work was done back in the early 1990′s. Remember NeXT? :-)

a friend of mine has made a plugin which does the trick depending on the spatial placement of the sound sources:

You can’t get better, and you can’t get it faster or with less work,
than buying a 1962 fretted Fender Jazz Bass, unfret it and then play
along the recorded bass lines. Anything else needs inventions which
might show up in 50 years and it still wouldn’t be better than the obove
mentioned method.

If you talk about just getting rid of noise, that is possible. I use
Soundhack with its spectral dynamics for that purpose….

But this has nothing to do with winamp EQ, its a fft based technique…

This only works if the unwanted noise is somehow regular and you can
catch a part within musical silence…
