Re: [PD] Advice on how to handle latency in linux with Pd, jack and ardour
Jack cannot automatically know that PD is reading from jack and then sending back to re-record. Because of how jack is designed, there is an inevitable and predictable delay there - determined by jack, not by pd. This has been brought up, ardour already automatically compensates for ladspa plugin latency when it has the proper information, so the infrastructure is theoretically there (ideally they could add a one jack period worth of latency correction toggle to the UI for each track). Simon Iten wrote: afaik all the latency introduced by jack is automatically corrected by ardour. so the latency you observe when rerecording in ardour comes from puredata only. there's not much you can do about this, except optimizing your patch. i'm not aware of any manual latency correction in ardour, but maybe i'm wrong, you should ask this on the ardour forum. you could start your sourceaudio with a short and loud click sound, that way it's easier to align later... regards, simon On Thu, 2009-12-03 at 11:50 +0100, Lorenzo wrote: I've been lately messing around with a fairly straight forward configuration sending audio from ardour to Pd's adc~ (through jack) and back to ardour via MIDI (for controlling automations) or audio (trivially re-recording Pd's dac~ output). In the case of MIDI latency seems no perceptible problem. In the case of audio, where the audio is of course 'processed' in the Pd patch and eventually 'goes back' to ardour, there is latency. This of course is expected for the nature itself of jack, what I'd like to know at this stage is not how to remove latency but the best way(s) to handle it (possibly even through raising the latency itself, as for the moment I'm not doing real-time), for example if there were some way to compensate it automatically (or at least in some 'smart' way). At the moment the best solution is to manually re-align the slightly delayed audio. Any input welcome.

Re: [PD] Max4Live... How about Pd4Live?
The Ableton / max integration is pretty awesome, and it will not be possible to integrate pd into ableton without the ableton source code or some difficult (and illegal) reverse engineering. And as far as open goes, ardour is more open without any integration with any other app (except, as Hans-Christof mentions, pervasively using jack to share audio) than live would be with both max and pd integration. Hans-Christoph Steiner wrote: I don't really know what Max4Live is, but I can say you've been able to send/ receive audio to/from Pd using Jack for years. I believe that the Pd jack implementation supports at least 64 jack connections, so if you use another Jack-enabled app, you can have up to 64 audio connections between them. People do this together with Ardour and soft synths, I saw a very nice demo of this in 2007 by Lluis Carbonell. The nice part of Max4Live is the GUI integration. You could do that with Pd the way Sven Koenig does: he tiles his windows so Ableton is on the top half of the screen, and Pd is on the bottom half.

Re: [PD] [OT] advice about low budget multichannel hardware configs
How important is phase between the channels? If channels drifting out of phase would be a problem, mixing in soundcards that do not share the firewire clock is out of the question. If they do not need to be in phase (ie. the channels are used for isolation rather than mixed for virtual positioning), then there are a larger number of cheaper options to consider. If they need to be in fixed phase than as far as I know firewire cards with a shared clock is your cheapest option aside from soldering soundcards to one another so they share a single clock. Firewire clock chaining is not limited to OSX, it will work under Linux too, and I would be surprised if it did not work under Windows. jurgen wrote: You have to be realistic - 25 channels is an extremely hardware ineffective configuration because audio interfaces come by increments of 8. Meaning for 25 channels you need 4 of those. I believe you can do it cheapest if you use OS X: you may borrow from friends any brand of device and then create in OS X an 'aggregate' device. This combines any number of any audio interfaces into one big virtual interface that you then can address with jack. It also solves the problem of the 25th channel because the aggregate device may include the machines in-built audio hardware on top of fw/usb things.

At least on a Linux platform, jack does actually start to approach this with certain firewire hardware (thanks to a well understood standard that has enough speed and bandwidth for good performance, some well done userspace drivers that avoid the legacy issues of oss and alsa, and some co-operative hardware vendors). I am not sure if this applies to platforms other than Linux though. Sadly the industry seems to be moving away from firewire and toward usb2, and usb2 has no implemented standard and very little vendor co-operation with open source developers. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] latency issue

Any other suggestions as to how I can get it lower? I really wanna use it for live performance. No. That is not the same as using it with jack, at least it would not be on a Linux system, I could be wrong about mac, but from what I know nothing compares to using jack, performance wise. Another issue could be externals, try measuring the performance without any externals loaded and see if one of the ones you are using is causing latency. Also, many commercial audio apps misreport latency; for example a large number, if not most of them, report only the latency introduced by the app itself, which is in their case actually cumulative with the latency introduced with the OS drivers and the latency inherant in the DAC / ADC of the card itself. With jack, at least, you are getting a much more accurate picture of the latency. This is based on reports of users who have measured their latency and compared it with latencies reported by jack and by mainstream nonfree software; there are actually applications to help you measure the latency you are getting by looping back a coded signal between the DAC/ADC and measuring the phase difference, this could actually be coded in PD and would be an interesting exercise come to think of it. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

(I must also add that I have no latency in any other music software I use: pro tools, digital performer, audacity, garageband etc.) I find this very hard to believe, is this just because you are auditioning your realtime input directly through the sound card? Because no software can process audio input and output a modified version without latency. Try playing through a plugin in realtime in protools or dp, I suspect you will notice a latency. If not, maybe you should be translating your pd patches into audio unit plugins, but I strongly suspect you will notice a latency. ... @Justin Glenn Smith: Do you have links or names of some of that measuring software you referered to?

Re: [PD] wacom external on os x

Yamaha nrpn uses msb and lsb addresses, hence the modification. (BTW Wouldn't nrpnin/out and rpnout make sense in the object db?) The difference between the nrpnout/nrpnout-yamaha and my nrpn_out is that mine uses only one ctlout object and uses rightshift instead of div, and mine does not accept a new channel from an inlet. The latter is an easy fix of course, the one I uploaded is a little harder to read and uses less RAM/CPU, for what it's worth. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

It is not so much a question of highpass vs. lowpass as it is a directional filtering - the pop filter attenuates the most direct path of the sound, and if I am not mistaken they are designed to attenuate more with a higher energy burst of sound (this attenuation achieved via air turbulence), in order to filter more strongly on the loudest sibilants (high pitched) and plosives (low pitched) while affecting the quieter sounds as little as possible. This turbulence theory may be wrong, I looked for confirmation or denial online but my google skills are failing me. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
