[music-dsp] Call for Contributions DMRN+7: Digital Music Research Network One-Day Workshop 2012
- Apologies for cross-posting - Dear Music Science people, Digital Music Research Network (DMRN+7) will take place in London on 18 December 2012. Please pass on to colleagues and other researchers who may be interested. Any abstracts by 16 Nov 2012 please! Best wishes, Panos. *** CALL FOR CONTRIBUTIONS *** DMRN+7: Digital Music Research Network 1-Day Workshop 2012 People's Palace Lecture Theatre One (PP1) Queen Mary University of London 18 December 2012 http://www.elec.qmul.ac.uk/dmrn/events/dmrnp7/ * Keynote Speaker Prof. George Tzanetakis (University of Victoria, Canada) will talk on Reinventing the vibraphone using non-invasive sensing. Digital music is an important and fast-moving research area. Sophisticated digital tools for the creation, generation and dissemination of music have established clear synergies between music and leisure industries, the use of technology within art, the creative industries and the creative economy. Digital music research is emerging as a transdiscipline across the usual academic boundaries of computer science, electronic engineering and music. The Digital Music Researh Network (DMRN) aims to promote research in the area of Digital Music, by bringing together researchers from UK universities and industry in electronic engineering, computer science, and music. DMRN will be holding its next 1-day workshop on ** Tuesday 18 December 2012 ** The workshop will include invited and contributed talks, and posters will be on display during the day, including during the lunch and coffee breaks. The workshop will be an ideal opportunity for networking with other people working in the area. There will also be an opportunity to continue discussions after the Workshop in a nearby Pub/Restaurant. * Call for Contributions You are invited to submit a proposal for a talk and/or a poster to be presented at this event. TALKS may range from the latest research, through research overviews or surveys, to opinion pieces or position statements, particularly those likely to be of interest to an interdisciplinary audience. Most talks will be 20 to 30 minutes, although there may be some flexibility to accommodate other lengths depending on the number of submissions. Short announcements about other items of interest (e.g. future events or other networks) are also welcome. POSTERS can be on any research topic of interest to the members of the network. Posters (A0 portrait) will be on display through the day, including lunch break and coffee breaks. The abstracts of presentations will be collated into a digest and distributed on the day, and authors will be encouraged to submit an electronic versions of posters (e.g. in PDF format) to allow the posters to be viewed after the event. * Submission Please submit your talk or poster proposal in the form of an abstract (maximum 1 page of A4) in an email to d...@eecs.qmul.ac.uk giving the following information about your presentation: * Authors * Title * Abstract * Preference for talk or poster (or no preference).

[music-dsp] need help with gnuplot and octave on my mac.
say, any among you using a Mac and Octave and gnuplot? i used to be
able to plot with Octave, it would start up X11 and if i set the
variable GNUTERM=x11 before starting Octave this would work. now it
doesn't :-(
anybody know what i'm doing wrong? i could use some help. thanks for any.

Hi guys, I wanted to let you know that we launched a free public beta of sonicAPI.com, a web API for music processing and analysis. For now, it features a limited set of zplane technologies (time stretching, pitch correction, reverb, tempo tracking, key detection, loudness analysis), but eventually, all of our SDKs will be accessible through the HTTP interface. Although at the moment this is rather basic (limited processing power, simple front end) we would appreciate your feedback!

Re: [music-dsp] sonicAPI.com audio processing service/API
Hey alexander and all! Thanks for the link - great service, hopefully we will see more of those in future ;) We, auphonic, recently also released a free RESTful web API for direct audio post production algorithms: - short introduction: https://auphonic.com/blog/2012/10/08/auphon...ion-1-released/ - homepage: https://auphonic.com - short video: https://www.youtube.com/watch?v=Y6uXP-MGt8I Some algorithms and features: - audio loudness normalization to new loudness standards (EBU R128, ATSC A/85 and more) - intelligent leveler, which balances levels between speakers, music and speech and applies compression as needed - audio restoration algorithms, e.g. the automatic noise reduction classifies segments with different backgrounds and automatically removes noise and hum - audio and video encoding to all common formats, metadata management automatic content deployment via Dropbox, FTP, SFTP, HTTP, YouTube, SoundCloud Someone could build a nice mashup of those APIs :) Thanks, LG Georg Am 2012-10-26 15:03, schrieb alexander lerch: Hi guys, I wanted to let you know that we launched a free public beta of sonicAPI.com, a web API for music processing and analysis.

Re: [music-dsp] need help with gnuplot and octave on my mac.
Hi Robert,
Not sure I can help because I am not a Mac user, but I do use Octave
and Gnuplot fairly regularly.
I wonder is there systematic change in the way Mac supports X graphics?
One thought, I stopped using environment variables with Gnuplot
and always use a .gnuplot config (according to man gnuplot it doesn't
need any ENV variables and prefers the .gnuplot file)

Re: [music-dsp] need help with gnuplot and octave on my mac.
Robert, did you upgrade Mac OSX to 10.8? If so, it no longer supports
PPC binaries via emulation, and it looks like you're using a PPC version
of gnuplot...

Re: [music-dsp] Please consider this Parallella supercomputer kickstarter
I've been discussing this Adapteva outfit's Kickstarter with a bunch of other embedded processing / ASIC / DSP guys and it just doesn't add up. For $99 they're promising a devboard which in addition to their parallel processing chip also contains a Xilinx Zync SoC that costs more than $200 in 1000pc quantity today. Assuming a low-ball BOM of $300/ea, that means they're going in the hole roughly $600k to build the ~3000 boards that they're currently promising. Considering that the $750k Kickstarter has to fund not only the devboards but also the NRE costs for the parallel chip production, it's hard to see how the numbers add up. Since it looks like they're closing in on the goal at a rate that will put them over the top in a few hours, it's likely that this one will fund. This means that if their business plan isn't viable, the backers are out their pledges unless the company works out a refund deal. I'd love to see this succeed - it's a neat idea and would be useful in a lot of areas, including music DSP. Something about it seems hinky though... TLDR: Approach with caution.

Re: [music-dsp] Please consider this Parallella supercomputer kickstarter
(because I guess I'm an NVIDIA whore?) I'm skeptical of the Adapteva claim of 50 GFLOPS per Watt on a system that only has 16 cores. The top of the line NVIDIA cards will only do 13 GFLOPS per Watt (single precision). No way are you going to get better power performance than GPU's with very large numbers of cores. I get that it's a pipelined RISC chip, which sounds a lot like the IBM Power series (I guess the modern equivalent is their BlueGene products). See the green500 rankings to get a better picture on what energy efficient supercomputers are like. For example, here http://www.green500.org/lists/green201206 The top efficiency for a supercomputer comes in at 2 GFLOPS per Watt. I won't say that alternatives to the Parallela project are cheap--but the processor sounds almost too good to be true. Once you add in the power requirements for the infrastructure built around that smokin fast multi-core processor, the total FLOPS per watt figure will decrease too. I for one have more computers than I care to learn how to program for already.

Robert, did you upgrade Mac OSX to 10.8?
no, i'm a luddite; 10.5 .
i didn't think i changed anything since the last time i used Octave to
plot something. there is a variable GNUTERM that gets set to x11 but i
don't know what other unix variable needs to be set to something.
thanx, douglas.

If so, it no longer supports PPC binaries via emulation, and it looks
like you're using a PPC version of gnuplot...

Hi Robert,
Not sure I can help because I am not a Mac user, but I do use Octave
and Gnuplot fairly regularly.
I wonder is there systematic change in the way Mac supports X graphics?
One thought, I stopped using environment variables with Gnuplot
and always use a .gnuplot config (according to man gnuplot it doesn't
need any ENV variables and prefers the .gnuplot file)

say, any among you using a Mac and Octave and gnuplot? i used to be
able to plot with Octave, it would start up X11 and if i set the
variable GNUTERM=x11 before starting Octave this would work. now it
doesn't :-(
anybody know what i'm doing wrong? i could use some help. thanks
for any.
