Nah, more like shortage of supply. You will get one. Recall would cost them too much so they want to get it as good they can. I think that’s case from what I hear.

“Compatible” is an iffy concept when dealing with analogue electrical values. Getting them as balanced and slick with all possible connections and variations is an art itself sometimes.

I can’t help but think if you want to stream to the net a dedicated system is better than just a piece of PC software and a home PC- but I also can’t think that a dedicated MP3 recorder, networked to a home PC or regular media swapping, might be less hassle and more reliable than using a Raspbery Pi as part of the recorder. Just my 0.02 cents, I wish you joy of the chase anyway.

Have a tune into our radio stream here, there very rarely any problems with sound quality and people are just using standard PCs/Laptops to stream.

I’d be amazed if it wasn’t powerful enough to do something with audio. also another part of the project (which should be easier) was to create a small size player for online radio (perhaps with some sort of graphics display) so you could use it away from your main computer/laptop, perhaps add speakers and amp to it like a micro system based on 1980s ghetto blaster (the big ones). its more a concept than set in stone and TBH much of this raspberry pi stuff is “a bit much for my old brain”, only just getting to grips with stuff like linux and back into AV after spending a lot of time with corporate IT stuff. Only recently got a telly with HDMI on it lol! hence why I threw the idea open to the younger folk with fresh minds…

OOh, just saw my first real one at close hand… These things are awesome in terms of potential!

A friend was borrowing it from a mate whose Dad picked one up etc etc etc… but they’re coming! THEY’RE COMING!!!!

It’s only 256mb, RAM, but the operating system is small enough that it takes up very little. You’d just need to plug in some USB cables for the audio because it doesn’t come with an audio input jack I don’t think.

Might be a plan to plug in a USB hub as a first step? Nope, no audio in as standard.

There’s a standard 3.5mm jack for audio out. You can add any supported USB microphone for audio in.

a small hub would be worth adding simply to provide a keyboard / mouse interface. TBH it would probably be worth starting on the audio playout section first as it would be easier, also I think this would encourage more folk to listen to our radio broadcasts at time of TX.

At present, “tuning in” means either being very near a computer, or waiting for one to start up, remembering the page/URL etc – whereas with a conventional radio all you need to know is the frequency. Also not everyone works in/with IT and has more than one computer or keeps it in the same area or connected to the rest of their AV equipment, especially folk who keep their hi fi downstairs.

Philips did make a “wifi online radio” but it was about £160 which is way expensive when a normal Band II set costs a fraction of the amount.

Another playout idea for broadcasters would be to emulate a cart machine for jingles, news, short voice items etc. whilst there is PC software to do this (one of the best ones was developed for our local community station), it normally means dedicating a PC for this (there are good reasons why for any broadcasting running all the same software off one PC is a bad idea).

A Raspberry PI connected to a normal cheap keyboard and even composite video would be perfect for this. Also via the NTP daemon it can provide a useful source of accurate time.

Yeah, but don’t forget, you don’t get an operating system. So whatever USB hardware you plug in – you got to have a compatible driver for it.

Processor on a Raspberry Pi isn’t x86 compatible. Oooh… some people are going to have SO MUCH FUN learning the joys of Acorn Risc to write their own USB drivers, let alone the rest of the software required. They’ll probably have receding hairlines within, ooh, minutes of realising this fact. I could be wrong on that but it is my understanding of the Pi.

The GOOD NEWS – ‘cos there’s a lot of interest then sooner or later solutions will appear. In terms of interfacing USB gear, at any rate.

I think that’s why GL wanted help from some of the guys what know programing off here. 😉
