[Douglas Repetto]

I get reports about this every couple weeks. Because it's a double opt-out
no one is actually being unsubscribed from the list unless they want to be.
So please ignore these bogus unsub messages. It's not worth spending time
worrying about it.

That's a function of your email client, not the list. The list just sends
through whatever you send to it. Your mail looks fine to me, no HTML to be
seen, nice formatting, etc. This is in Chrome/gmail. So if you're seeing
markup then it's your client that's displaying it as code instead of
rendering it.

[Douglas Repetto]

We've had a couple of these in the last week. The list requires a
confirmation email for unsub requests, so I don't think anyone has
actually been removed. I'm not sure there's much to be done about this
sort of thing.

[music-dsp] [admin] list etiquette

[Douglas Repetto]

Hi everyone, Douglas the list admin here.

I've been away and haven't really been monitoring the list recently.
It's been full of bad feelings, unpleasant interactions, and macho
posturing. Really not much that I find interesting. I just want to
reiterate a few things about the list.

I'm loathe to make or enforce rules. But the list has been pretty much
useless for the majority of subscribers for the last year or so. I
know this because many of them have written to complain. It's
certainly not useful to me.

I've also had several reports of people trying to unsubscribe other
people and other childish behavior. Come on.

So:

* Please limit yourself to two well-considered posts per day. Take it
off list if you need more than that.
* No personal attacks. I'm just going to unsub people who are insulting. Sorry.
* Please stop making macho comments about first year EE students know
this and blahblahblah. This list is for anyone with an interest in
sound and dsp. No topic is too basic, and complete beginners are
welcome.

I will happily unsubscribe people who find they can't consistently
follow these guidelines.

The current list climate is hostile and self-aggrandizing. No
beginner, gentle coder, or friendly hobbyist is going to post to such
a list. If you can't help make the list friendly to everyone, please
leave. This isn't the list for you.

Hi,

Just a reminder that if you are new to the list you should read the
music-dsp FAQ. It contains answers to both technical _and_
adminstrative questions that often come up on the list. If your question
appears in the FAQ it is safe to assume that it has been discussed on the
list many times in the past, and you should probably have a look through
the list archives before posting your question to the list.

[music-dsp] [admin] list blurp

[Douglas Repetto]

Hi everyone,

Columbia is switching some servers around, so there may be a slight
blip in the list sometime this week. Hopefully no big deal. The list
address should stay the same, and the archives will be preserved.
Everyone will be resubscribed to either normal or digest mode,
although if you've tweaked any of your other settings they will be
lost. And if you're set to no mail for some reason, you won't be
transferred. You also won't receive this email, so it'll be a big
mystery!

Hi,

Just a reminder that if you are new to the list you should read the
music-dsp FAQ. It contains answers to both technical _and_
adminstrative questions that often come up on the list. If your question
appears in the FAQ it is safe to assume that it has been discussed on the
list many times in the past, and you should probably have a look through
the list archives before posting your question to the list.

Hi folks,

This is generally a friendly, tolerant list. I feel like this conversation

for a bit to try and reset the tone.

Let's give each other the benefit of the doubt and assume good intentions -

Re: [music-dsp] music-dsp mailing list digest settings

The digest doesn't go by number of messages, it goes by size. It was

know how that feels.

 We (well, at least I) only get 2 or 3 emails,

 less messy if I didn't had subscribed to the
 digest version, since then I could have read the
 subject of each mail in the mail list overview.

 I've looked into the configuration, and couldn't
 find a way to set this number myself.

 I think other digest users agree with
 me about this, since on other mailing

 like 10-20 mails (plus at least one mail
 per 24 hours if there had been any posts

 I realize that this is slightly off the beaten path for this group,
 but it's a problem that I've been trying to solve for a few years:

 I had written software for notation-based composition and playback of
 orchestral scores. That was done via MIDI. I was working on porting
 the original C++ to C#, and everything went well...except for playback.
 The world has changed from MIDI-based rack-mount samplers to computer-
 based samples played back via hosted VSTi's.

 And unfortunately, hosting a VSTi is another world of involved software
 development, even with unmanaged C++ code. Hosting with managed code
 (C#) should be possible, but I don't think it has been done yet. So
 I'm stuck. I've spoken to Marc Jacobi, who has a managed wrapper for
 VST C++ code, but VSTi hosting is still not that simple. Marc is very
 helpful and generous, and I pester him once a year, but it remains an
 elusive problem.

 It occurred to me that one of the resourceful people here may have
 ideas for working around this. What I'm looking for, short term, is
 simply a way to play back orchestral samples or even guitar/bass/drums
 as a way of testing my ported C# code. Ideally send note-on, velocity,
 note-off, similar to primitive MIDI. Continuous controller for volume
 would be icing.

 Any ideas, however abstract, would be greatly appreciated.

[music-dsp] [admin] music-dsp FAQ

[douglas repetto]

Hi,

Just a reminder that if you are new to the list you should read the
music-dsp FAQ. It contains answers to both technical _and_
adminstrative questions that often come up on the list. If your question
appears in the FAQ it is safe to assume that it has been discussed on the
list many times in the past, and you should probably have a look through
the list archives before posting your question to the list.

Re: [music-dsp] Duplicate digests?

[Douglas Repetto]

Hi Mike,

What address have you been using to contact me? I haven't received anything
from you.

I'm sorry about the extra digests. No one else has mentioned it, which
suggests it's a problem with your email provider or client. Resubscribing
with a different address would be a good test. You could also toggle the
digest setting.

Let us know if those ideas work.

Best,
Douglas

 Is anyone getting multiple mailings (duplicates) of this digest?

 It started for me about a week ago.

 I sometimes get over 10 duplicates within a day.

 I contacted the list-serve moderator - they have not responded yet.

 Could a rogue subscriber be doing this unintentionally?

 Any ideas how to resolve this?   Unsubscribe/resubscribe?

 Regards,
 Mike

Re: [music-dsp] DSP/Plug-in Developers in the Big Apple

[Douglas Repetto]

Well, the music-dsp list lives in New York City! And all of the
universities in the city have active computer music programs. Plus there
are lots of freelance developers and several audio-oriented startups. I'd
recommend checking out the various music hack days, hacker spaces, dorkbot,
experimental music venues, etc. All sorts of interesting audio fun
happening in NYC!

 *and* there's a lotta good music.  unfortunately Tramps and the Bottom
 Line are gone, the Knitting Factory ain't what it used to be, but life goes
 on and now there is the Rockwood Music Hall.

 what else might you suggest, glmrboy?  Bowery Ballroom?  now i only visit
 the place once every odd-numbered year (in the fall).  but when i'm there,
 it's the Rockwood i go to.

 i still love NYC, even though i don't get there as often as i wish.

Urs, I don't know if you're referring to music-dsp here, but this list 
is specifically not meant to be in the academic realm, but rather a 
place where people of all sorts with an interest in music and digital 
signal processing can chat. So I encourage you to share your results here!


I'm sorry there has been unpleasantness on the list recently.

we might just share it in more practically oriented place (KVR dev
forum).

Re: [music-dsp] Missing replies for the past year or possibly more

[douglas repetto]

I've just added a new obnoxious warning to the reminder that goes out to 
the list 2x a month. We should obviously change this policy in some way, 
but I can't deal with it at the moment. I'll figure something out soon.


Sorry for the missed messages and disrupted conversations.

douglas

Sorry to anyone that has tried to get feedback from me in the past
year or more, I have been posting but in html format, and the email
list deamon failed silently so I never knew they weren't making it

time to put together. I'll search through my sent mail and re-send a
bunch of emails.

All the best,

Hi,

Just a reminder that if you are new to the list you should read the
music-dsp FAQ. It contains answers to both technical _and_
adminstrative questions that often come up on the list. If your question
appears in the FAQ it is safe to assume that it has been discussed on the
list many times in the past, and you should probably have a look through
the list archives before posting your question to the list.

[music-dsp] [admin] Re: HTML

[douglas repetto]

Hi list.

I'm on the road, so a full response will have to wait awhile. A couple 
quick notes:


* the HTML mail no bounce issue is specifically mentioned in the faq:
http://music.columbia.edu/cmc/music-dsp/musicdspFAQ.admin.html

* there have been times when the list and server were being attacked 
24/7 by 1000's of spam robots, which is why the list is configured in 
this peculiar way. Not sure of current situation.


* I'm of course all for making the list as useful as possible to all 
involved, and will take a look at our options when I return mid-month.


best,
douglas

  Here are some other papers that are worth looking at.  One of the more

I've found the multi-band Klapuri approach [6] to be quite effective for
detecting notes with strong attack transients.  For notes with less
pronounced attacks, the method covered in [5] is designed to detect
changes in pitch.  The method in [5] is also discussed in the tutorial
paper [4] (Spectral features using phase), so definitely read that paper.

And FWIW, maybe it's time to change that. Spam filters have gotten a lot 
better in the last few years. This is an OLD list, and back in the day 
attachments/HTML caused lots of problems.


What do you all think? Should we allow HTML/attachments?

Hi,

Just a reminder that if you are new to the list you should read the
music-dsp FAQ. It contains answers to both technical _and_
adminstrative questions that often come up on the list. If your question
appears in the FAQ it is safe to assume that it has been discussed on the
list many times in the past, and you should probably have a look through
the list archives before posting your question to the list.

Sorry, I looked at rbi's peak spec and it is symmetrical—I was

Oh, and for cut…it depends on if you want symmetrical response or

multiplying by the A^2 factor so it ends up on top)

OK, I had (well, took) time to think:

You need to divide the numerator by the gain (A), and multiple
the denominator by the gain (aka multiply the numerator by
A^2). That will keep the peak at unity. Swap the numerator and
denominator if you want the EQ to be symmetric for cut and
boost. If you need the BLT worked out, let me know.

Thanks Nigel - I have just been playing around with the
pole/zero plotter (very helpful app for visualising the
problem) and thinking about it. You guys are probably right
the simplest approach is just to scale the output and using
the peaking filter.

Additional optional mumblings:

I think really there are two 'correct' solutions to
manipulating only the coefficients to my ends (that is,
generation of coefficients which produce filters
interpolating from bandpass to flat):

The first is to go from pole/zero to transfer function,
basically as you (Nigel) described in your first message -
stick the zeros in the centre, poles near the edge of the
unit circle and reduce their radii - doing the maths to
convert these into the appropriate biquad coefficients. This
isn't really feasible for me to do in realtime though. I was
trying to do a sort of tricksy workaround by lerping from one
set of coefficients to another but on reflection I don't
think there is any mathematical correctness there.

The second is to have an analogue prototype which somehow
includes skirt gain and take the bilinear transform to get
the equations for the coefficients. I'm not really very good
with the s domain either so I actually wouldn't know how to
go about this, but it's what I was originally thinking of.

Thanks for the help

Thomas-it's a matter of manipulating the A and Q
relationships in the numerator and denominator of the peaking
EQ analog prototypes. I'm not as good in thinking in the s
domain as the z, so I'd have to plot it out and think-too
busy right now, though it's pretty trivial. But just doing
the gain adjustment to the existing peaking EQ, as Ross
suggested, is trivial. Not much reason to go through the fuss
unless you're concerned about adding a single multiply. (To
add to the confusion, my peaking implementation is different
for gain and boost, so that the EQ remains symmetrical, a la
Zolzer).

Yes I think this is essentially my problem, there are no
stop bands per-se just zeros which I was basically trying
to lerp away - which I guess isn't really the correct
approach.

The solution you are proposing would work I believe; along
the same lines there is a different bandpass filter in the
RBJCB which has a constant stop band gain (or 'skirt gain'
as he calls it) and peak gain for the passband - so a
similar technique would work there by scaling the output.

However I was hoping to avoid scaling the output since if I
have to do that then I might as well just change the
wet/dry mix with the original signal for essentially the
same effect and less messing about. I feel in my gut there
must be some way to do it by just manipulating
coefficients.

Re: [music-dsp] need help with gnuplot and octave on my mac.

Robert, did you upgrade Mac OSX to 10.8? If so, it no longer supports 
PPC binaries via emulation, and it looks like you're using a PPC version 
of gnuplot...

[douglas repetto]

Hi,

Just a reminder that if you are new to the list you should read the
music-dsp FAQ. It contains answers to both technical _and_
adminstrative questions that often come up on the list. If your question
appears in the FAQ it is safe to assume that it has been discussed on the
list many times in the past, and you should probably have a look through
the list archives before posting your question to the list.

Re: [music-dsp] ### Pointers for auto-classification of sounds?

metric doesn't get stuck on a local minimum and miss the global minimum.

Andrew Horner, of course, has written many AES articles about applying
GA to parameter estimation for a variety of synthesis techniques, most
often wavetable synthesis (of which i have an interest).


I agree. Genetic Algorithm/Evolutionary Programming are cute names that 
have stuck, and are quite resonant, even though they're the cause of a 
lot of confusion and spurious discussion. That said, especially in the 
early days, there was quite a lot of earnestness in regards to the 
parallels with real evolution. I'm not at all trying to say that 
GAs/etc. aren't useful for lots of things. They are.

Phil, these are nice examples, but they really highlight the difficulty 
of using the evolution metaphor in a consistent way. What, exactly, is 
evolving?

If you just start with something that generates a sequence of numbers
then it is not likely to generate audible tones very quickly. But nature
did not start out making sound using non-oscillating number sequences.
Wind was howling and rain was generating grains of sound before life
even evolved.


I agree with this, but if the goal is to make/twiddle physical models of 
sound producing physical situations, then the evolutionary metaphor 
isn't needed at all.



Animal sounds arose from the beating of insect wings, or from breath
causing flabby bits of flesh to oscillate in the throat. Matter
resonates naturally. So it seems fair to start a GA with some resonating
elements. Maybe you could evolve a network of mass+spring units
connected together randomly. They would quickly make some audible sound.


But again, this begs the question of what is actually being evolved? 
Starting with a phenotype (network of mass+spring units) and using that 
to specify a genotype and then using that to wiggle around the features 
of the phenotype is exactly backwards in terms of evolution. That's not 
to say that it's not interesting or useful, just that it's a real mess 
if the story you're telling is that you're somehow using evolution.




Add in some higher level fitness functions for communication or
species recognition and you could evolve some nice soundscapes.


And this is what lots of people have done to make interesting work. But 
I would argue that it's a lot more like intelligent design then it is 
like evolution. And again, I'm not saying that's bad. Just that there's 
a level of romance/wishful thinking involved in telling ourselves we're 
doing something that's like evolution. And I think the core of that is 
the idea that biological evolution (and whatever came before biological 
evolution kicked off) managed to create something (us!) out of nothing. 
Wouldn't it be wonderful if we could do that with our computers?!? 
Except that we can't.
