Re: [PD] [OT] Pd to play sounds simultaneously on 8 speakers with cheap computer
Just started some docu on puredata.info especially for BBB (to be updated next week with new mor up to date reports). http://puredata.info/docs/embedded/ http://puredata.info/docs/embedded/bbb/sound/ cheapest 8 channel USB sound-device I know of and working: Logilink 7.1. Cutting the power of the USB cable, adding a filtered powersupply helps for the sound quality which is quite the same as the ESI card for unsymmetrical DAs Testing and feedback is appreciated. mfg winfried Am Sonntag, 30.

There's definitely a lot of quirkiness to getting it running... for example ALSA gets in an infinite restart loop when attempting low latency on pd-extended, but vanilla starts up fine under the same settings. And then there's the fact that an issue in the kernel screws up USB audio on major distros like Raspbian. I'm using the Satellite CCRMA distro right now with much better success. So far I've got various delays, a looper, and a waveshaper distortion running within the same patch, at 20ms latency with very few noticeable dropouts. Parameters are adjustable with a QuNeo MIDI controller and with a button attached to the GPIO pins. The Pi is a bit more affordable than the UDOO boards, but then again I had to buy a powered USB hub. Ultimately for one audio input the Raspberry Pi could probably serve most purposes, while the UDOO is more likely to scale to bigger installations. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -- --- Ritsch, Winfried, Ao.Univ.Prof. Dipl.-Ing.

[PD] [OT] Jobs: PhD fellowship in Spatial Audio and Signal Processing
Hello, sorry for off-topics, but maybe somebody interrested in. Kategorie: Jobs Titel: PhD fellowship in Spatial Audio and Signal Processing Verfasser: Brigitte Bergner (IEM) Contact: office _at_ iem.at ___ The Institute of Electronic Music and Acoustics group of University of Music and Dramatic Arts Graz, Austria invites applications from outstanding investigators for a PhD student fellowship to contribute and take part of the Advanced Audio Processing Project. This project is founded by the “Österreichische Forschungsförderungsgesellschaft (FFG). Advanced Audio Processing (AAP) is a consortium built on three internationally successful audio research groups at Graz University of Technology (TUG), University of Music and Dramatic Arts Graz (KUG) and Joanneum Research (JR), and three internationally active and successful Austrian companies (AKG Acoustics, Atronic Austria and Philips Speech Processing). The scientific partners are considered as the most important Austrian research groups in the field of advanced audio processing. They have many years of experience and will now bring together their competencies to build an “audio processing expertise center” in Graz. The industry partners of the consortium are among the most important companies in Austria that implement top-level audio expertise within their products. We are looking for post-graduates who have already profound knowledge in digital signal processing. The applicant will operate within the field of spatial audio processing and perceptual audio evaluation. Therefore besides comprehensively programming skills in MATLAB, C and Pure Data (PD) knowledge within psycho acoustics is necessary, too. Further required abilities should comprise experience with experimental design, self management, ability to work in a team, and the proof of scientific paper writing. CV and publication: Applicants should provide a CV with relevant publications to '[EMAIL PROTECTED] target=_blank target=_blank’ before 12th of December 2008. Decision will be taken on the 19th of December. The annual salary for the proposed fellowship amounts to 33 600 EUR (gross income). The proposed position within this AAP project is planed for a period of 2 years.
