g729 Codec Calculation


Sr = 8kps (Sample Rate – How often audio is sampled per second.)
Ss = 20ms (Sample Size – This is the duration of each sample delivered. (Can also be 30ms))

Pb = Payload in bits
PB = Payload in bytes

To calculate BW usage:

8000 / 50 (g729 sample size / codec transmission rate in pps)

160 Kb / 8
20 KB

Sr / Ss = Pb / 8 = PB + headers

Never perfect is it :|

Seems the IOS5 shipped on Apple’s new iPhone 4S is bugged.

Mine is claiming 4.4GB is in use by “Other”. This seems to be a common problem shared amongst the community.

Once such report is https://discussions.apple.com/thread/3442555?tstart=0

Time to backup and reinstall I think.

Oh and..

I got an iPhone 4!

Well… It was a week ago 🙂

I’m pretty happy with it too. It’s only the 16GB (free upgrade) but It’s a shit load better than the 3GS (obviously), I’d list why but a tech spec comparison on the Apple site is a much better move.

If I did have to name one particular feature, it would have to be the Retina display! It’s gorgeous to look at and somehow pleasureable to touch.

I definitely, definitely like this screen.

The text is sharp, icons are clear and colours are all perfect.

If you don’t have it, you’re missing out. Big time.

I wonder if it’s that simple…

In the run up to IOS v5.0 being released I thought I’d try and update my 3GS to 4.3.3. I keep having performance issues (apps closing, slow response to actions etc) so I figure that 4.2.1 could well be the cause of my issues and as it’s quite a little out of date it really needs bringing closer to the currently released stable version (4.3.5).

I wonder if it’s as simple as just Updating through iTunes…?

So, in summary…

Just completed my first post using the WordPress app for the iPad.

Hardly intuitive.
Keyboard doesn’t integrate quite as well as I’d hoped.. no copy+paste on short cuts, keep having to touch the screen which is exactly what I wanted to get away from…

Perhaps I’m missing something?

Maybe I should have bought the dock…

edit: Just found out how to select all, cut, copy and paste all from the keyboard. Rather than CTRL+key its CMD+key!

Good ol’ Apple eh 😉
