iPhone as Sound Level Meter

[mjb]

This looks pretty neat for iPhone users, turn your device into an audio signal scope, level meter, or signal generator: http://www.faberacoustical.com/products/iphone/

wow....that looks nifty...although I'd have to say it can't be ALL that accurate.

I have one on my Windows Mobile PDA phone... I forgot where I got it though, half of it is in chinese. It's fun to play with for stuff like loud sports events or movie theaters and such.

that iphone one looks pretty awesome though.

I agree with Dougie--cool, but not a tech spec microphone you're using.

Now if you replace the internal mic with a nice quality microphone or something....could be useful

Apparently the second generation iPhone microphone is not too bad, and there is a calibration process to nullify it's effects further.

From their website:

The iPhone’s built-in and headset microphones exhibit a remarkably flat frequency response, making them suitable for basic sound level measurements. However, due to sample rate limitations and frequency response degradation, SoundMeter is not recommended for use with the built-in microphone of first-generation iPhones.

Even though default sensitivity values are included for the iPhone’s built-in and headset microphones, for best results, SoundMeter should be calibrated before use. Sound levels may be off by 6 dB or more when using the default microphone sensitivity.

The all mighty and powerful Iphone. I love it.

I'm just impressed by their detail in describing the frequency response of the phone's mic!
