I'm just returning to your post again to refresh my memory of your advice.
Btw, my comment there was just about how I can come across a long "article" and you're not quite sure what it's going to be about.
Often I'm opening up several links to scan them and see if any of them might address something I'm researching, so it helps to know early on what it's going to be about - that was all.
Anyway, I had this idea to use a bluetooth transmitter, and people could listen using their cell phones, as where I am here in San Francisco, almost everyone has a bluetooth enabled phone.
But then I read that there is always a tiny delay with bluetooth transmissions because of the time necessary for compression of the signal. It might be even worse if you take into account how long it would take for the iPhone, whatever to decompress.
People say it's not an annoying delay if it's pretty short.
It's a bit unfamiliar territory so I'm not sure. And that's why I returned to your article to have another look.
What kind of radios to people bring along ? I have a pocket Sony FM radio that was something like $8 on Amazon, and it's actually quite good.
I don't know anyone else that actually owns a small FM radio though. I guess I could buy a bunch of cheap ones and the couples could share one with a headphone splitter jack.
Just thinking about all this.
Ok, so a little background for you. I've had my BYT since 2005, since 2006 I have broadcasted my audio, first over AM, because I had an AM transmitter already. I didn't like the way speakers worked in my yard so it was a natural step. Eventually I made the investment in an FM transmitter. So I don't really know what my AM transmitter did in it's previous live but it came with 4 radios that we fixed to AM 650, actually they were built to only receive that channel. So folks bring their own radio and if they forget I have 2 that still work I can loan out (1 was stolen 1 quit working). Today I actually transmit using both the AM & FM transmitters just because I want to continue to use the AM loaners that I have, that and I'm a sap for old technology.
Back to your question about radios. I've seen all kinds. Some cell phones today apparently have FM receivers so a few folks do that. Some bring a small portable, some walkmans. After all these years all the regulars are use to it so it's not an issue except for the occasional newbee who doesn't know or someone that has there batteries run out. But that's where the loaners come in. I highly doubt that you would need to supply a radio for everyone, but it would definitely be a good idea to have at least a couple loaners available. When I first started broadcasting my sound it was common for all 4 radios to get loaned out, now it's maybe once or twice a month that one will get loaned out. Like anything folks get use to it.
Two reasons I went to broadcasting my sound back in 2006, one was I didn't like having speaker wires all over my yard, and my yard was so big I had to crank the sound so loud that it would get the neighbors all worked up. Having folks bring their own radio meant a couple of things to me. No more speakers to setup and take down as well as lower over all sound volume because folks had their radio right next to them rather than speakers across the yard. I had a pretty strict volume rule at the theater before we moved it, and I had several regulars that walked in each night with a Walkman and head phones. Listen to it as load as you want on headphones no one will complain. I have never had to require everyone to use headphones, though I did consider it in the early years at one point. I never had to go that route.
Honestly when I wrote the article I had no idea that someone would be thinking broadcasting Bluetooth, and to be honest with you I didn't realize that you could even do that. With that in mind if and when I write a ver 3.0 I will make it clear early on that it is radio broadcast and not some other form. I took no offence to your comment merely tried to explain reasoning, of course at the time I didn't realize you were looking for Bluetooth info. It's all good on my end anyway.
So for me radio broadcasting has worked out really, really well and I wouldn't want the hassle of speakers and the associated wiring and equipment, but that doesn't mean that it's right for everyone. Please let me know if you have other questions, I really enjoy the topic and am happy to help.
