MP3 streaming data usage
Anyone have any idea how much data would be consumed each day streaming MP3 at 128kbps audio stream rate? Thanks.
BEER Not multicast - point to point, US / NZ over TCP. I was refering to traffic in Gb's. The 128kbps is the audio stream rate, obviously there is an overhead on this. I need to know how many Gb we're talking prior to obtaining ISP quotes. /BEER

128kbps, if you multicast it.

Start with 128kbit/s and work out an estimate based on that, perhaps.

/me hands John a calculator...
128kbps = 16kbytes/sec = 960kbytes/min
= 57ish Megabytes/hour = approx 1.3Gbytes per 24 hour period
(Excluding overheads etc)

Thanks, I'm trying to come up with a pretty accurate figure that includes up/down traffic, for quote obtaning purposes.

I am not fimilar with the specifics of MP3 data streams I thought someone here might have figures based on experience.
Hi John, I would recommend buying a flat-rate connection at 192kbps. That way when your server gets attacked you won't get hit with a bill for $10,000 in excess data charges. You might pay anywhere between $300-$600/month for such a flat rate service, depending on where you get it delivered. Streaming audio internationally on a capped plan isn't a particularly good idea.

Good day sir,
Anyone have any idea how much data would be consumed each day streaming MP3 at 128kbps audio stream rate?
It's probably something in the order of 128kbps, multiplied by the number of seconds in a day.
Maybe. YMMV, IANAL.

It is appropriate. We own and manage Internet connected networks and streaming media comprises a substantial part of utilised Internet bandwidth in most ISP networks.

Otherwise beer, beer and more duff beer...

46MB per hour 1105MB per day 7741MB per week 34283MB per month which is why most Radio stations stream at 32kbps and use a better codec Don't get into video, the numbers are bigger :-)

Good thing you pointed that out, John probably didn't realise. John, 128kbps MP3(or whatever) will use.... 128kbps per connection, as several people have tried to point out. The overheads are negligible. -Richard
I am sorry, did I neglect to mention that it is point to point. US / NZ, for streaming vertical interest (ethnic) programming for broadcast over FM in New Zealand. Streaming over the web may happen, but phase one is to use FM as the delivery method.

Here's a stab at the overheads. By the looks of RFC2250 when you take a 44.1kHz 128kbps mp3 and RTP stream it, the minimum you can send it as is a single 417 byte frame. So 3336 bits of MP3 data +128bit RTP header +16bit UDP header +20bit IP header gives a 3500 bit frame you need approx 40 of those a second to give you 128kbps of audio rate So thats a total bitrate of 136.71875 kilobits/sec over 24 hours thats 1.40815973 gigabytes So even with a worst case overhead (not taking into account an insane PMTU) everyone is in the ballpark with approx 1.5G/day Dean Richard Patterson wrote:
