Thread: Decibel Meter?

is a discussion within the

I had one on my old Nokia 5100. Anyone care to make one for the iPhone? Seems like this platform would make one hell of a DB Meter!

    Ask the author of the Guitar Tuner application.

    He already has to sample the microphone in order to get it to hear what sound you're producing, it shouldn't be too much harder to get it to use the data it already has available to measure the sound pressure levels and then display that information.

    (The app that calls itself "Guitar Tuner" doesn't use input...you are probably thinking of Funiculus Guitar Tuner). I would doubt that a decibel meter is feasible...it is a whole lot of calculations (on top of a fast fourier transform), and would require some sort of calibration. However, I'm not an expert on sound-math, so I may easily be wrong...

    It's not a dB meter, but you can try running Funiculus and looking at the amplitude meter. It correlates with dB. It won't give a dB value, but it will allow you to compare one day with another.

    VNotes has a meter that has units in dB, but I wouldn't call a dB meter...it shouldn't register negative values in the presence of sound.

    There is one in the AppStore, it's called SoundMeter, so it is possible.

    Anyone care to make a free one for Cydia/Installer? :P Or a free one on the AppStore?

    I have SoundMeter and it's quite accurate. I recommend it.
