[PD] writesf~ time to flush to disk…?
Hi folks, The documentation for writesf~ states that: You need not provide any disk access time between open and start, but between stop and the next open you must give the object time to flush all the output to disk This suggests that once writesf~ has received a stop after writing to disk, there is no way to determine whether i) writesf~ is ready to receive another open or ii) the file written to disk is ready for reading. Could an outlet be added to writesf~, outputing the number of samples written to disk? The parent patch could then use this outlet to establish when writesf~ is ready to receive another open.

Of course the changes should be applied, I'm just saying I thought the Connect button label was a little confusing. Apply would work as well in this case, but I think something like Update Connection Settings etc is more verbose, but also more clear. What I meant by not having an apply button a few posts ago, was that in most Mac apps you don't have a 2 step process to change settings aka change then apply. When you change a setting that's it, it's both changed and updated at the same time. I do agree with Jonathan that, in this case, it makes sense to have a 2 step process. I was mainly pointing out I thought the labeling could be more clear. Actually, I don't think I expressed myself very well as I was arguing the opposite. I think the settings should take effect immediately and there shouldn't be an apply or connect or anything button — you just change a setting and that's it — done! Hence my question about when you would want to not apply the settings. I can't find any other application on my Mac that has an apply button in the audio prefs dialog, and FWIW, in Integra Live we managed to create an audio prefs without an apply step, based on Pd using IOhannes' [mediasettings] externals, so it's definitely possible. best, Jamie ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

My question: are all current (and imaginable future) audio APIs able to handle quick changes to the setttings? Say, if a user toggles Use Callbacks three times within 500ms and Pd tries to connect to ALSA each time, does ALSA handle that gracefully? (Or whatever backend-- I can't remember if ALSA has that option available atm.) I think that's a separate issue to whether or not you have an apply button. That is, you could have an apply button, but still be in a situation where the user can change state faster than the backend can respond. In any case, I think adding a UI component the purpose of which is to throttle user input is a bad idea. I don't want to be slowed down ;) I think you should design what you think is the best UI for humans, and then figure out how to make the business logic robust enough to handle problematic cases like the one you describe above as and when they arise.

What if someone wants to change two or more settings without having them activated until all is correct? On the Mac network settings you have an apply button so you can change multiple things without getting stupid error messages because it's only half set up... That makes sense (kind of) for Network Settings because there's a degree of mutual interdependence between the settings — although I'd still prefer no apply (iOS doesn't have one for example). But in the case of audio / MIDI prefs the settings are independent once you've selected driver and device, so users explicitly wanting _not_ to apply a setting immediately seems like an unlikely corner case to me.

It is possible that this problem stems from some weird configuration on my system but before I try digging in that direction, just wanted to see what everyone else's thoughts were on this one. The problem btw manifests both on local build of pd-extended and pd-l2ork. Not sure about vanilla... To add to this, jack-dssi-host fluidsynth-dssi.so works perfectly fine. In pd/pd-l2ork when creating [pluginhost~ fluidsynth-dssi.so] works (creates 3 outlets and reports no errors) but trying to open the gui does nothing. I do get a warning about DSSI path not set, but its defaults are correct (and the external finds the .so file fine). Trying something like [pluginhost~ calf.so:Reverb] (or reverb) or any other legitimate combo that uses :plugin crashes pd immediately. Has anyone else had any luck with it or has any alternatives? My intention is to fully support [pluginhost~] on Linux (dssi~ is deprecated and surpassed by pluginhost~), although I don't use Linux much these days, so I may not notice bugs quickly. I am away from my computer right now, but I'll take a look at these issues tomorrow morning and hopefully provide a fix.

Is that correct? anyhow: originally OSC did not define how to transmit OSC-packets over a stream-based protocol like TCP/IP (that has no notion of ending packets). implementations that wanted to transmit OSC over stream-based protocols had to find solutions for themselves. a few years ago, the OSC specs have been extended, to explicitely mention SLIP encoding as the means to packetize streams of OSC-data. This was added to OSC 1.1, iirc. OSC 1.0 proposed to prepend to each OSC packet a 4 byte header that contains the byte count of following OSC packet. Old versions of [packOSCstream]/[unpackOSCstream] implemented this proposal. The latest version of liblo does exactly this. See liblo-0.26/src/send.c at line 411. It actually sends a packet containing only the length of the OSC message that is sent next. Thanks everyone, for the helpful suggestions and insights. It turns out that liblo-0.26 does indeed use the 4-byte header extension, however the current liblo git revision also contains functionality for using SLIP instead. I tested this with [unpackOSCstream], and I am now able to correctly receive OSC messages over TCP from liblo just fine. In case anyone finds this thread, looking at a similar issue, the solution on the liblo side is (with liblo from git), to add a call to lo_address_set_flags() on your lo_address before calling lo_send_*, i.e.: lo_address_set_flags(address, LO_SLIP); best, Jamie ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] bi-directional OSC over TCP from liblo
Hi all, Apologies for the rather esoteric question. I'm trying to send OSC to/from Pd over TCP using the liblo OSC library and the mrpeach/ OSC externals [tcpserver], [packOSCstream] and [unpackOSCstream]. I've attached my testing patch. I am able to connect to [tcpserver] from liblo, and receive raw bytes. However, [unpackOSCstream] seems unable to unpack the data. It just outputs nothing for the bytes received. Likewise, if I send to liblo from [tcpserver] using the |client( selector, liblo crashes with the message error? message too short?. So, it seems like [packOSCstream] and [unpackOSCstream] are (un)packing message in a format that can't be used with external clients/servers. Is that correct? Has anyone else managed bi-directional communication using OSC over TCP with an external application?

Re: [PD] bi-directional OSC over TCP from liblo
Hi Pedro, Thanks for the reply. To clarify I can OSC over *UDP* from liblo to/from Pd just fine using the mrpeach externals. It's using TCP, where I run into trouble. I think it's due to the streamed nature of TCP, and message boundaries, but I am not an expert on this.

So you send from liblo and pd receives, but no data unpacks? Did I get it write? If you open a ./oscdump on command line you get the data? (meaning it would be a pd-side issue...) Yes that's correct. There is an example echo server that comes with liblo. I can get bidirectional communication liblo - using this example. If I replace one end of the communication with [tcpserver], liblo can connect, [tcpserver] receives data, but [unpackOSCstream] can't seem to unpack the data. Likewise [packOSCstream] doesn't seem to generate a data format that liblo can understand. best, Jamie ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

The question to answer is: who are the people going to be building this from source? The vast majority of users will want to download the binaries and never even think about the source code. From my experience, I would guess that people who would want to compile it themselves will likely be interested in DSSI and LADSPA for other things also, and therefore will need to have those headers in a simple place for other projects too. I probably came across as more grumpy about this than I actually am! I agree with the exact points you've made here, but I can also think of cases where it's more desirable to commit things to svn. I tend to take a pragmatic view, weighing up the reasons for / against on a case-by-case basis. In this specific case I think you're right that the people compiling from source are likely to be on either a Linux audio box or Mac with Fink / MacPorts / Homebrew so I'm perfectly happy with the decision to remove the headers :) Does pluginhost~ work on Windows? I didn't realize that. Does anyone distribute dssi or ladspa binaries for Windows? It *should* work on Windows. The Audacity project provides a bunch of LADSPA plugins for Windows: http://wiki.audacityteam.org/index.php?title=Ladspa_Plug-ins pluginhost~ doesn't require that the UI part of DSSI is running, so it should make it possible to run some of the synths under Windows with no GUI.

Not the zero'th device, because for Output devices, both outputs are prefixed with (0). Why is Microphone truncated to Microph? Are these names coming from Portaudio? Or is Pd additionally mangling the names? best, Jamie ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Looking for a way to add bytes to beginning of a file using [binfile]
On 20 Sep 2012, at 17:33, Antonio Roberts anto...@hellocatfood.com wrote: I'm attempting to use [binfile] to add additional bytes to a file. If I first read the file - using [read( - and then specify the write position - [writeat 0 ( - when I add bytes they _overwrite_ the already existing bytes instead of adding new ones. Previously I have used one [binfile] object to read a file output each byte of it to another [binfile] object. This method has worked great for small files but when I'm faced with 60mb files it takes far too long! Is there a way to add bytes to the beginning of a file without overwriting? DId you solve this in the end? [binfile] could be trivially extended to allow an |insert( method, which inserts bytes without overwriting. However, I suspect this kind of insert operation is going to be relatively inefficient even if it's done on the C side. Another option, as I suggested off-list is to use [shell] + cat, but this isn't portable. Something else you could explore is using [pdlua] and a bit of Lua script: http://www.lua.org/pil/21.2.2.html For the sort of work you're doing it wouldn't hurt to incorporate pdlua into your toolbox anyhow. best, Jamie ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] packOSC integer marshalling
Hi list,
It looks like the mrpeach [packOSC] external converts Pd floats to OSC integers
if the float value is equal to the float value cast to an int. From the source
code:
/* It might be an int, a float, or a string */
switch (a-a_type)
{
case A_FLOAT:
f = atom_getfloat(a);
i = atom_getint(a);
if (f == (t_float)i)
{ /* assume that if the int and float are the same, it's an int */
returnVal.type = INT_osc;
Implicitly converting floats to integers based on an arbitrary rule seems a bad
idea to me. Why bother making the conversion? Why not send floats as floats?
It's certainly going to cause problems for some clients. For example, if the
client is expecting floats on a given OSC address, it may get:
0.5 - float
1.0 - int ???
1.5 - float
Which may result in dropped values or other anomalies.
I am happy to send a code patch if people agree that this is a bug or at least
bad design...
best,
Jamie

DspFuncLib is in: /System/Library/Extensions/AppleHDA.kext/Content/Plugins/DspFuncLib.kext/Contents/MacOS. If you run command nm on the lib, you'll see a plethora of dsp functions like MultiBandCompressor, NoiseCanceller, Loudness, Softclip, Limiter and whatnot. Functions in this lib are called when the internal soundcard is used. When using an external soundcard with Pd, DspFuncLib is not called and that makes the big difference in CPU load. AppleHDA and mach_kernel are Apple libs as well and together with DspFuncLib they are responsible for the crazy CPU load in the 'idle-but-dsp-on' case. PortAudio functions are apparently statically built into Pd and they consume very little CPU time. It seems that you're right, so I've closed the bug (my apologies to PortAudio!). I guess the real 'fix' for this is that Pd now has a block size setting in Preferences. With a block size of 1024, using the PortAudio driver I get a CPU use of 2% with DSP on. Checking use callbacks also seems to reduce CPU. Here, I got a reduction of ~2% with that checked. Also, I'm not sure if this is an improvement in recent versions of OS X, but Pd now runs at only ~5% with DSP on using the PortAudio driver with a blocksize of 64.

Only after turning dsp on, and off again, the adc/dac are off. As you're on OSX, you can use the magnificent performance profiler Shark.app to get a better view of CPU load of functions. Most CPU time for adc/dac is consumed by DspFuncLib, AppleHDA and mach_kernel. Apparently, the system does a lot of processing on the audio stream without us asking for it. There's denoise, equalizer and fft functions amongst others. I don't think Pd can influence these routines, except by not using the adc/dac. CPU load for adc/dac depends on hardware.

It seems I need to create the graph then switch DSP on. Jamie ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Pd 20% idle CPU usage on MBP

I think I already wrote about it on pd-list this autumn, no...? But it's hard to search the archives about the frequency of that thread, as the keywords might not be consistent. I just know that the problem has existed for quite a few years and that I read about it on pd-list more than a handful of times. Indeed! I remembered it coming up and so I searched the archives before posting, but keywords like 'cpu' and 'usage' don't do very much. However, digging a little with Shark, I see that a high proportion of Pd's CPU time is spent talking with the audio hardware, so I try Google: DspFuncLib portaudio, and lo and behold: http://www.google.co.uk/search?q=DspFuncLib+portaudio Trouble is use jack doesn't solve the problem, it merely avoids it. So, zooming in a bit, I see at least two issues here: 1. there is a lot of activity in the underlying audio drivers when using the Portaudio driver on OS X, even when audio is off in the application. Let's call this the 'idle' CPU usage. IMO, this should be less than 1% on modern CPUs for well behaved applications. I've added this to the bug tracker. 2. there is a lot of activity in the underlying audio drivers when using the Portaudio driver on OS X, when audio is on in Pd. Comparison with AudioMulch, which also uses Portaudio suggests that is only in part a Portaudio problem. AudioMulch idles at ~10% on my machine. I suspect that the problem with Pd+portaudio may be due to a small buffer size used by Pd. I thought Pd's 'Delay' setting in audio preferences was supposed to handle this, but changing delay to 500ms, has no effect on CPU use. Also added to tracker.
