Re: [PD-dev] libPd hanging audio and other questions
Hi Dan, Thanks for your help. I know they're holding off the rewrite in OF 7 due to time and budgetary constraints, but we think there was another reason why it kept hanging. A, external I wrote in C gives out sample accurate events (rather that block-aligned ones) as well as a signal. The outlet_float statements were embedded within the DSP loop. You can get away with this in Pd running on a computer, but it doesn't work on an iPhone. This may be bad programming (I'm not sure - I taught myself) but it does cause Pd to crash when DSP is turned off in ofxPd on iOS. The DSP never got turned off and a chunk of audio was left looping, regardless of what the DSP chain was supposed to be doing, both in the simulator and on the device. Anyhow, I re-coded the external using a Pd clock to block-align the events and the problem went away. And I have finally learned to use clocks in Pd external coding! Ah, what fun I'm going to have ,-) Does anyone know what the standard blocksize for writing RT audio from memory to the SD card in an iPhone is? That's another problem we're facing. Drop-outs happen when recording, and we think it might be because we need to deal with the audio in certain size chunks, but we're not sure what that size might be. And do they have to synchronize with Pd's block size (i.e. 64 samples) in order for this to work?

I'm not entirely sure which version we're using, but the ofSoundStream.cpp file is only 140 lines long. If we upgrade to the latest ofxPd, will it still work with OF 6.2?

Re: [PD-dev] Rewriting a unified phasor / metro object for reading tables
Thanks Katja. I'm doing things in a quick and dirty manner, to see if they work and so that they can be implemented quickly for the 100,000 or so downloads we've had, but I want to get it right. We'll have a testflight version next week so we'll be able to test the new version (it's like a heart transplant for the app). The first thing is that it has to work with the limited resources of the iPhone4 (the most basic device we are supporting). The second is to make it better, so that we can move from tabread~ s to tabread4~s, but I think this'll be just for the iPhone5. I really want it to be super efficient, so I'll study your code. Interesting that the original phasor~ relies on a double precision variable for the wrap. Sometime we need to move onto 128bit architecture, but probably not too soon ;) Cheers, Ed PS thanks for answering the question I asked.

Re: [PD-dev] Filter design for iPhone
mvcf~ - Well, it breaks when the Q is high and freq is moderately high, or at high freq and Q, but it seems to be that the higher you get with either frequency or Q it has a greater probability of breaking (all dac~ outputs at 1 (or possibly 1e+07), no more audio can be played by the patch. What I mean is that with the noise~ object as the input, the filter breaks after about 1-3 seconds when Q=0.70-0.8, f=0.7-0.8, and there are variations on this depending on the settings. Something is profoundly un-robust about this filter, but it's cpu load is very low. I want to have a stable version for not much more CPU. I will look at the RJDJ filters mentioned also. I would like not to have to worry about filters when programming libpd audio engines. It would be nice to get a really efficient IIR with a musical response that uses low CPU into the core - I am not an expert at using poles and zeroes however (but I'm working on my higher math often these days, with the Khan academy :) Some of this is subjective, perhaps the musical nature of filters, but certain types of filter are assumed by many (musicians, DJs etc) in this part of the world to be normally available. The 24dB lowpass resonant filter a la Moog is one of them, and a fundamental analogue processor as well. I understand the analogue better than the discrete, so I'm anxious to know what limit is reached in the coefficients of the filter that causes the undefined result (NaN).

Re: [PD-dev] denormals: svf, freeverb (was Re: [PD] bug in freeverb???)
as stated before in this thread, denormals can slow down the computation on the fpu. the problem is not as big, when compiling the binary to use the sse unit, though (btw, this is the default, when compiling for x86_64) Indeed, but externals that run a little slow are better than those that crash PD in the middle of a performance! This is why I'm trying to find a way of fixing the externals that suffer from this. moog~ is another! Meanwhile, I've rolled back to the old svf~ external so that the metastudio drumsynths don't crash. I had a very successful gig last night as a result.. Who wrote the old svf~? pd devel_0_39 did also set the DAZ/FTZ flags, which affect the denormal handling on the sse unit, but that was never merged into vanilla pd I see there's a new pd_devel branch. I should check it out.

Re: [PD-dev] denormals: svf, freeverb (was Re: [PD] bug in freeverb???)
I wonder if this line, right after you check in for denormality, might not be causing trouble: // very slight waveshape for extra stability sv-b = sv-b - sv-b * sv-b * sv-b * 0.001f; Since cubing a tiny number and multiplying it by .001 could end up creating a denormal, which isn't checked for until it's gone through a series of further computations and ends up as the new in. Could be, but I tried applying an the exception handler to sv-b (which has a cubed version of itself - 0.001f taken away from it) and still pegged the CPU. Also (I don't really know), I thought that denormals were caught as a processor exception whenever they occurred, so neutralizing them in the code after the fact won't do anything to speed up the process, except to prevent a cascade of denormals. The thing to do would be to replace the exception handler with your own. It seems from the article you flagged up that the Denormals-Are-Zero (DAZ) mode we really need is an SSE instruction. I wonder if you can do this without using intrinsics and native Intel code. I think there's some resistance to this since the code is meant to be compilable on PPC, i386, i686 and all variants, not just P3-and-beyond, and I'm trying to make my work generically compatible with all Pd-Extended distributions from 0.39 onwards. To avoid serialization and performance issues due to denormals and underflow numbers, use the SSE and SSE2 instructions to set Flush-to-Zero and Denormals-Are-Zero modes within the hardware to enable highest performance for floating-point applications. Once again, I personally would like to have this implemented in the PD core, since denormals are a real pain in the ass and often cause CPU pegging. This limits the real-time uses of PD, since there are some performance patches that are realizable but ultimately un-performable. As such I'm surprised it doesn't class as a bug, but I guess this is up to the extern writer. I notice a post on the pd-dev list - denormal bashing for feedback filters - ID: 1145279 cpole~ and rpole~ filters are not denormal save(sic) yet How did zmoelnig fix this I wonder?

[PD-dev] denormals: svf, freeverb (was Re: [PD] bug in freeverb???)
We have to sort this out! The denormals bug in freeverb~ _seems_ to have been fixed by following Julius' advice. I made a makefile with -fno-trapping-math as a flag and so far so good. I haven't had a problem with the freeverb~ object pegging the CPU. May I advise that this is implemented in PD-extended, since it causes my patch to NOT WORK AT GIGS! I simply cannot take any more embarrassment. I want to play live, otherwise there's simply no point doing anything! The second one I have discovered is in bsaylor/svf~ and there's no makefile for this in the subversion repository. I notice in the source code there is a FLUSH_TO_ZERO definition. Interestingly, when I try to compile this external using a bog-standard makefile on Ubuntu 8.10, it causes an error: cc1: warnings being treated as errors svf~.c: In function ‘run_svf’: svf~.c:59: error: dereferencing type-punned pointer will break strict-aliasing rules svf~.c:60: error: dereferencing type-punned pointer will break strict-aliasing rules Now, I'm trying to unpick the statement: #define FLUSH_TO_ZERO(fv) (((*(unsigned int*)(fv))0x7f80)==0)?0.0f:(fv) which is being called on lines 59 and 60 of bsaylor/svf~.c, causing the compiler to choke, and (perhaps) causing my drumsynths to break! And by the way, where is the source code for the _other_ svf~ external?

You should also be able to add a small constant to the input signal. I notice gcc has the option -fno-trapping-math which may make the problem disappear if my theory is correct. (I hope the FPU simply sets underflows quietly to zero when no trap can be generated.)

[PD-dev] bug???!?!?
Hi there, I've encountered this before, but now it has sabotaged one thing I wanted to play at pdcon, I want to work out why it happens. Enclosed is a folder containing two versions of my clinoker~ drum synth. On one of them, the filter for the noise generator does not work, and on the other it does. The only difference between them is an [envrms~] measuring object on the frequency signal to the filter - but it's not even in the chain of signals that affects anything. Have a look. Ideas please?

OK. I tried it before with vanilla, but I was using the same pd/extra directory as pd-extended.

Re: [PD-dev] poly library
Yep, that's true, but OTOH a wrapper is just a Pd patch, which is much easier to change than a dynamic patching construct. That has to be taken into account when it comes to longer-term maintainability. Generally less dynamic patching is better. Well...if objects to be used within a dynamic patching system conform to some kind of standard, then dynamic patching is a good thing. I'm using it a bit in the forthcoming release of metastudio. It's really time-consuming and cumbersome to create large polyphonic structures in PD. So I'm making a client in which my machines can be dynamically created as patches. Can anyone explain to me why the dynamic patching aspect of PD is not documented? Some have suggested that it might change at some point in the future. I can't see how basic [obj $1 $2 myvoice $3 $4...$n-1( syntax could change without a radical change to the structure of PD. Can anyone enlighten me?

OK, so I thought I understood cvs, but what as I thinking? again, the v3directory shows up on the autobuild, but I'm sure I deleted that this week. Am I missing something? I sync-ed my (local) externals repository with the cvs on sourceforge, and then from there I deleted all the files in maskxor/v3, removed v3 and deleted erroneous files in cvs repos, then committed those changes.

[PD-dev] error handlers
Hi list, I've just been looking through source code from cvs, picking at random, and looking for an example of the void error (char *fmt, ...) from the externals howto. I can't find one anywhere! Am I stating the obvious here? It's just that this means that PD patches made using anything other than internals are almost impossible to debug if they're extremely complex like mine is: there simply isn't a way of finding out where the errors are occurring. I think, IOhannes, if you could explain to me precisely how to use this function, I would be willing to (slowly) go through and make some changes. This is a massive hole in PD! Could PD or desiredata have a step-trace function, like MAX? Ouch!

Re: [PD-dev] error in maskxor in CVS
Hey Tim, Sorry, that's my fault. I was a klutz, and uploaded from a messy directory. Can anyone tell me how to get rid of stuff from the repository? I only uploaded before, and it seems that until now I have not made this silly mistake (but I did commit some bad code a week ago ;-( ) These things happen. Until I sort it out you can just delete everything except the files maskxor.c, maskxor.pd_linux, help-maskxor.pd and makefile from the maskxor directory (including that stupid v3 directory) and the compilation will work.

Here is our function prototype: EXTERN void *copybytes(void *src, size_t nbytes); The thing to see here, is that it doesn't actually copy the data to a location you specify.

So... if I initialize the pointers the first time they are used, maybe that
will help. It makes sense that the _new routine would be causing the problem,
since it crashes when I load the object (PD disappears...)
I'll try it!

I guess because you don't initialize the pointers the first time. Your
maskxor_new has:
SETFLOAT(x-masking.maskr[0], 0);
SETFLOAT(x-masking.maskl[0], 0);
SETFLOAT(x-masking.maskxor[0], 0);
...but x-masking.maskr etc. don't yet point to anything, they were
declared as:
t_atom *maskxor, *maskl, *maskr;
...but not given any value. If it doesn't crash right there it will do
so when you try to free the pointers:
if (x-masking.maskl) {
freebytes(x-masking.maskl, x-lengthl * sizeof(t_atom));
x-masking.maskl = 0;
x-lengthl = 0;
}

Re: [PD-dev] Trouble with memory+pointers
Splendid! It doesn't crash any more. It doesn't work either, but at least I'm
in more familiar debugging territory! Thanks.
I used a x-firstl, x-firstr and x-firstx variables that were tested and set,
so that the first time each list is initialized, the first thing that happens
is e.g.
x-masking.maskl = getbytes(n * sizeof(t_atom));
and then the freebytes is used the second, third, fourth etc times.
