Glitch
by michael strohmann 04 Jul '18

04 Jul '18

Hello! from time to time my patch produces this beautiful, but unwanted glitch. (audiofile attached) are there any ideas what could cause this behaviour? i am running this on a RPi B+, using sfplay~ to playback a 4 Channel Audiofile. the playback is triggered via a sensor/GPIO or via OSC. restarting the RPi eliminates the glitch. the only thing i can think of is that there is a "memory leak” in one of the objects, that uses up the RAM and eventually produces this glitch. but i am not a c++ programmer, so this is a wild speculation. in any case i would not know how to solve it…. cheers! Michael

pd list/text objects possibly causing audio dropouts when used a lot?
by Matt Davey 03 Jul '18

03 Jul '18

Have been hunting down some possible causes of audio dropouts, and it seems that [list] and probably also [text] are possible causes. Removing them and replacing with table lookups whenever possible certainly seems to have helped. Are these objects calling memory on the audio thread? Is that possibly the issue?

Good question. I don't believe so as that work will be in the next libpd release. I've been behind on this and we may just put out what we have soon/now. The main thing holding it back is a big fix for iOS sample rate conversion. > On Jul 2, 2018, at 6:34 AM, pd-list-request(a)lists.iem.at wrote: > > Date: Mon, 2 Jul 2018 01:17:52 +0200 > From: Johnny Mauser <joson.android(a)googlemail.com <mailto:joson.android@googlemail.com>> > To: pd-list(a)iem.at <mailto:pd-list@iem.at> > Cc: pd-announce(a)lists.iem.at <mailto:pd-announce@lists.iem.at>, Joe Bowbeer <joe.bowbeer(a)gmail.com <mailto:joe.bowbeer@gmail.com>> > Subject: Re: [PD] [PD-announce] pd-for-android 1.1.0 released > Message-ID: > <CAMJUsDZc5u=E0bbdWVansAasdVBNMPqsORzG09A-uUC6eWFWjg(a)mail.gmail.com <mailto:CAMJUsDZc5u=E0bbdWVansAasdVBNMPqsORzG09A-uUC6eWFWjg@mail.gmail.com>> > Content-Type: text/plain; charset="utf-8" > > Hi Tal, > > Cool thing! > Does this include a new libpdcsharp.so compatible with other projects?

[PD-announce] Release of tpf-client / tpf-server
by Roman Haefeli 02 Jul '18

02 Jul '18

Hey all Let me a announce a by product that was created while working in a research group exploring formats for telematic performances. tpf-client[1] is a graphical multi-instance jacktrip clone built in Pure Data. It establishes low-latency multi-channel audio connections between two or more endpoints. Unlike the traditional jacktrip utility, it doesn't require any of the endpoints to have public IP address, a requirement that is hard to fulfill in many concert venues. The client connects to a server - the tpf-server[2] - that keeps track of connected clients and lets client agree on common parameters like samplerate and blocksize. The server acts as a UDP proxy between clients and thus allows clients to send audio among each other even when they are behind firewalls. Alternatively, clients may establish a direct peer-to-peer connection by using a technique called UDP hole punching. This feature is still considered experimental and may not work in certain network environments. We have been successfully using this setup in a number of concerts with two or three concert venues and the additional latency due to the UDP proxy was small enough for our purposes, since we run the server close to our university. The client comes pre-configured to use our server running at telematic.zhdk.ch. However, we advise other interested groups to set up their own server for productive use, on the one hand to keep latency as small as possible, on the other hand we're still doing experiments and might restart or adapt services. If groups or institutions are interested to use this setup, we would appreciate to get some feedback. Contact me directly. The client: [1] https://gitlab.zhdk.ch/TPF/tpf-client Standalone-App for macOS: https://gitlab.zhdk.ch/TPF/tpf-client/tags/v1.0.0 The server: [2] https://gitlab.zhdk.ch/TPF/tpf-server Thank you, Roman _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce
