Comment on Streaming Audio from Raspberry Pi – part 2 by stefano zorzanello

thank you for your interest!
yes I’ve to look for this USB GPRS modem that supports ARM Linux drivers……. maybe this will be the rock to climb…. I’, pretty sure you will find a more stable sound card…
I was wandering for arduino plus audio codec shields… but it seems that arduino has not enough resources to support both 3g shield and audio codec at the same time……
any way I’ll keep on studying the feasibility…

in the while thank you very much..

ciao

Hi Stefano, your project sounds interesting. I think you can do step 2 with the Pi but you’ll need to find a USB GPRS modem that supports ARM Linux drivers. I have no idea about that though. Also, I found the soundcard I bought not to be very stable: at times the driver seems to crash and the streaming stops. Unfortunately I have very little time to debug this. I’m considering shopping for a board that has native audio input and similar cost.

Hi Stef,
thank you for your great report about Pi audio streaming…..
I’m completely new to this great world
I would like to know if you think the Raspberry Pi would be the right shield for my project.

I am a musician and sound designer, using Max/Msp, particularly interested on soundscape projects and researches, and this project is for an interactive sound installation in a real environment, with the sound produced by cicadas. As I’d prefer not to abandon a computer in a field, I assumed to use a microcontroller for this purpose.

So Raspberry Pi should be involved in steps 1-2-4-5 of the following:

1) sampling the sound locally produced by cicadas males during summer: mono signal is fine.
2) sending a stream of samples through the web in real time: Raspberry Pi should be connected to the web via 3G (no ethernet cable).
3) another computer placed in a studio should get this stream, making the audio treatments, re-sending it trough the web (splitted possibly into four independent synchronized channels-signals)
4) downloading the 4 processed streams;
5) distributing the sounds on a local multi speaker system, 4 channels basically.

If you think that all this is feasible through a Raspberry Pi plus a proper internet networking shield, I would buy it as soon as possible. Could you also tell me in case it would be possible with only 2 channels (stereo) playing?

I thank you very much for your attention, I stay waiting form an answer from you.

Best regards

stefano zorzanello

This is the card I bought: http://www.frys.com/product/6003878;jsessionid=RyXR42h9SrmVCea1JaYN6A__.node2?site=sr:SEARCH:MAIN_RSLT_PG

Could you please give som more information about that soundcard? Can’t find it at Creative.

Comment on Ubuntu is getting closer to Windows and Mac (in a dumb way) by Stef

Even if disabling workspaces is for new Ubuntu users, why on earth does the installer disables them for *old* users like me during the *upgrade* (not a fresh install)? I found this bug https://bugs.launchpad.net/ayatana-design/+bug/868423 where the rationale for this move is explained… The answer is not convincing and there is no evidence to support the decision. If this was my product I would have preferred to keep the option and worked on teaching new users how to make advantage of it: you gain users by showing the power of a tool, not by dumbing it down to the lowest common denominator.

I used unity once, it wasn’t my laptop and there was tons of notifications. That gets me crazy, notifications for emails (mostly spam), notifications for tweets (spam again), gTalk notifications, facebook notifications, facebook chat notifications.

…and…

tons of windows opened in a single workspace. ARGH!

Well, just imagine non-geeky non-techy guys switching to Ubuntu it is very confusing at start. May be it is because of that they disable work-spaces by default. I just hope that they don’t do more changes like this. Although agree with you on how dumb this release can get.

@smaffulli except for code available, right to fork, price, participation, etc

@smaffulli NOBODY, not even Shuttleworth himself, messes with Stefano’s keyboard shortcuts.
