Measuring Microphone input sound wrt decibels and frequency

Recommended Posts

Hi All,

I am new to VB and I need your valuable suggestions on the following requirement,

- I need to build an App which constantly monitors the decibel and frequency of computer's microphone input and records it when the input is of a certain frequency and decibel combination.

- I am not aware of the restrictions of VB6, so if this is not possible, please suggest alternate technology and also how to go about this with that particular technology.

Any help is greatly appreciated. Thanks !

I'm not sure about microphone inputs with VB, but assuming you can get the input waveform in some kind of data array, you'll want to lookup the Fourier Transform (or an implementation of the FFT) in order to convert time domain waveforms to get the frequency content.
