Yes, it is. Apple's sounds effects are royalty-free.

I would like to try recording sleep with an iPhone, connected to a power source overnight. However, I'm not sure if the default camera is capable of recording videos that long. A colleague suggested using a video codec with very few key frames, just saving the changes between frames.
My questions are twofold - are there any open source projects that already do long(3+ hours) video recording on iPhone. How would I extract the file from the iPhone if it is 3 Gb or so in size?
At first glance this doesn't really appear to be a programming question...but you hint that you may be looking for open-source code for a video codec.
However I thought I might shed a bit of light on the iPhone itself.
If you're recording at 320p, that averages out to about 15mb per minute. Calculating 8 hours, equals 7.2GB.
To my knowledge, there is no time limit, just the limit of your iPhone empty HD space. However, some people have reported that the video recording stops sometimes, seemingly randomly, during very long recordings.

I am trying to build a webpage that shows the video of a webcam on live.
Right now, I have no webcam, so I'll have to buy one. I don't mind how much it costs, I just want it working with a good resolution (at least 720p).
I don't know which kind of camera I should buy and which programming language is better for that (if it's possible I would prefer not to use Flash).
Can you help me?
Sorry for my bad English, I'm trying to improve ;)

To show in a webpage, you can use IP-Camera. They cost a little more, but they can serve their images as independent network node. They also supports voice and live compression (H264 and MPEG4).
Best brand is Axis, but there are lots of options.
For Axis camera models, adding view to page would be as easy as add this item to your page:
<img src='http://192.168.1.20/axis-cgi/mjpg/video.cgi'>
It works for most browser, not IE. For IE, they have support as well here.

I'm currently doing an internship in a medical laboratory
They want to buy Ipad and medical device connected to it
example: diabet tester http://www.ibgstar.us/
blood pressure monitoring system http://www.ihealth99.com/
I'm wondering if I can code my own application that gets the data from the medical device and then handle it?
thks for your answers
I think they're some step to success it .
At first you need a Hardware solution like said "Mundi".
You need to grab data from device and store them somewhere accessible (like in a BDD with online acces).
And then the iPad application just have to connecte to the data-Source and play with it
The short answer is YES.
There are many ways to get the data into the app via a network. If you would like to read from the device directly, you would have to additionally find a hardware solution.
I'm not sure this applies, but I've seen some really cool medical apps written using Harvard's SMART project. They provide a simple but effective framework, which is independent of the Hospital Information System (like Cerner, Epic, VistA).

I am working on a musical instrument app for iPhone and need sample sounds that I can use for the various wind instruments. I'll be using OpenAL with looping, so a 1 second sample that is spot-on in-tune and without vibrato or other variation is essential.
My question is: Where can I find audio samples that are, or can be converted to .CAF format for looping play? Need these to be "realistic" sounding, not electronic sounding. Not looking for freebie, looking for professional quality.
Thanks in advance!
Here's the command for converting to CAF format:
/usr/bin/afconvert -f caff -d LEI16#44100 myaudiofile.wav myaudiofile.caf;
Regarding finding samples, there's a ton out there. Search Google with "free audio samples".
Magazines like Sound On Sound and Computer Music will often have deals. Although sometimes you'll need to buy the magazine, or be a subscriber. They do lots of reviews of commercial sample CDs. Often these are quite reasonably priced (e.g. $50).
As with everything, the key is to check the license carefully to make sure it's full use and that you can redistribute in your app. That also applies to samples that you can download for free.

I need to develop an iPhone/iPod application which runs in the background and can measure audio output. It is part of a research project to measure how loud people have their music. Unfortunately I am unfamiliar with the iOS 4 SDK.
Ideally, the application would have to know if headphones are plugged in, be able to measure the volume of the audio signal being outputted (and calculate some data) and then be able to, at some point, update data to a central database.
Taking into account the multitasking capabilities, is it possible to develop such an application for the iOS 4?
I am aware that multitasking on this platform is quite limited, however I also noticed that audio processing seems to be possible (only to an extent perhaps?)
Here's a question which shows how it can done, but unfortunately, you can only do it for your app (or more correctly, I should say only when your app is active), you can't add a global hook to be notified in the background when the volume is changed by another app.
iOS (4) doesn't have background services like Android which is what I believe you're looking to do.
