Subject:Re: [AUDITORY] review of harmonic+noise segmentation softwareFrom:Colin Raffel <craffel@xxxxxxxx>Date:Tue, 1 Oct 2013 10:38:53 -0400List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--089e01537f209c353304e7aeeaef Content-Type: text/plain; charset=ISO-8859-1 Matt, A good historical overview of sinusoidal modeling which includes sines+noise and a few extensions is here: https://ccrma.stanford.edu/~jos/pdf/SMS.pdf SPEAR is a popular choice for sinusoidal modeling (without noise): http://www.klingbeil.com/spear/ Professor DAn Ellis has some Matlab code for doing sines+noise modeling: http://www.ee.columbia.edu/ln/rosa/matlab/sinemodel/ I don't know of any software packages which perform, for example, sines+noise+transient modeling but I imagine they must be out there. A related technique which has seen a lot of focus is harmonic/percussive separation or transient/steady state separation. There have been many techniques proposed; my favorite is FItzgerald's method because of its simplicity and effectiveness: http://arrow.dit.ie/cgi/viewcontent.cgi?article=1078&context=argcon There is an implementation available in librosa: https://github.com/bmcfee/librosa/blob/master/librosa/hpss.py Hope this is helpful. -Colin On Mon, Sep 30, 2013 at 7:48 AM, Matt Flax <flatmax@xxxxxxxx> wrote: > Hi there, > > Back about 10 or 15 years I remember that some people on this list were > researching the segmentation of sound into tonal components and noise > components. > > I was wondering whether anyone on the list has used any free software > libraries which come from this research to do this and if so whether you > could let the list know ? > > I am intersted in software which can do more then monophonic segmentation > ... if possible. > > thanks > Matt > --089e01537f209c353304e7aeeaef Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr">Matt,<div><br></div><div>A good historical overview of sin= usoidal modeling which includes sines+noise and a few extensions is here: <= a href=3D"https://ccrma.stanford.edu/~jos/pdf/SMS.pdf">https://ccrma.stanfo= rd.edu/~jos/pdf/SMS.pdf</a></div> <div>SPEAR is a popular choice for sinusoidal modeling (without noise):=A0<= a href=3D"http://www.klingbeil.com/spear/">http://www.klingbeil.com/spear/<= /a></div><div>Professor DAn Ellis has some Matlab code for doing sines+nois= e modeling:=A0<a href=3D"http://www.ee.columbia.edu/ln/rosa/matlab/sinemode= l/">http://www.ee.columbia.edu/ln/rosa/matlab/sinemodel/</a></div> <div>I don't know of any software packages which perform, for example, = sines+noise+transient modeling but I imagine they must be out there.</div><= div><br></div><div>A related technique which has seen a lot of focus is har= monic/percussive separation or transient/steady state separation. =A0There = have been many techniques proposed; my favorite is FItzgerald's method = because of its simplicity and effectiveness: <a href=3D"http://arrow.dit.ie= /cgi/viewcontent.cgi?article=3D1078&context=3Dargcon">http://arrow.dit.= ie/cgi/viewcontent.cgi?article=3D1078&context=3Dargcon</a></div> <div>There is an implementation available in librosa:=A0<a href=3D"https://= github.com/bmcfee/librosa/blob/master/librosa/hpss.py">https://github.com/b= mcfee/librosa/blob/master/librosa/hpss.py</a></div><div><br></div><div>Hope= this is helpful.</div> <div><br></div><div>-Colin</div></div><div class=3D"gmail_extra"><br><br><d= iv class=3D"gmail_quote">On Mon, Sep 30, 2013 at 7:48 AM, Matt Flax <span d= ir=3D"ltr"><<a href=3D"mailto:flatmax@xxxxxxxx" target=3D"_blank">fla= tmax@xxxxxxxx</a>></span> wrote:<br> <blockquote class=3D"gmail_quote" style=3D"margin:0 0 0 .8ex;border-left:1p= x #ccc solid;padding-left:1ex">Hi there,<br> <br> Back about 10 or 15 years I remember that some people on this list were res= earching the segmentation of sound into tonal components and noise componen= ts.<br> <br> I was wondering whether anyone on the list has used any free software libra= ries which come from this research to do this and if so whether you could l= et the list know ?<br> <br> I am intersted in software which can do more then monophonic segmentation .= .. if possible.<br> <br> thanks<span class=3D"HOEnZb"><font color=3D"#888888"><br> Matt<br> </font></span></blockquote></div><br></div> --089e01537f209c353304e7aeeaef--
