I am undertaking a project where i desperately need help.
I am aiming to push sound via wifi to users devices (ipads, iphones, Samsung devices etc possibly via VLC media player or a similar client).
Now heres the rub. I need the sound to play simultaneously to all the devices. The sound file would be an hour or two worth of broadcasting or streaming all via wifi.
How does one go about this? A vbrick or similar? Any software solution? Different type of hardware solution?
Any ideas of costs?
I would ideally want the client side to be free but dont mind paying on the server side.
Any help would be most appreciated
Welcome to the forum.
I'm not sure you can accomplish what you are attempting, depending on how you define "simultaneously". If you mean to have all devices playing in sync, such that hearing multiple devices all sound as one, then you are unlikely to get there with dissimilar devices. Wifi will also be an issue.
The only devices that I am aware of that allow synchronized audio are Airplay devices and Sonos. Neither use wifi. It is possible to do this with wifi, but only if you use multicast, and I don't know of any devices that support multicast (VLC probably does). Even with multicast, each device would need to maintain the same amount of data in its buffer in order to stay in sync.
If you don't need all devices to stay in sync, then you could look for software that supports the SIP and RTP internet protocols.
Many thanks for that.
Yes all devices need to be in syn. Basically all users would in effect watch a movie on a large screen but sound would be piped to the devices via wifi.
or that what we were aiming for anyway.
Airplay and Sonos? they are a type of speakers if im correct?
I would ideally need something inexpensive for around 50 users.
Seems a simple idea when we first thought about it but its quite complicated it seems.
Many thanks for your insight. Much appreciated Mark
Sonos is a proprietary wireless HiFi system. If you are looking for something inexpensive, this isn't it.
Not that hard to do, if you just try not to make something harder than it should be. Also, there is no way that every user is going to sit there watching the whole loop, or listening to it the whole time, most will just stop it and go on their way, doing something else.
I just came across this thread and I would like to say that I have been working on a technology that might interest you all. :)
I have been working on it for 6 months now.
Its called the Übercaster, a Real-Time Audio Broadcaster WiFi Hotspot. (http://echosdesign.com)
