Analog signal sound indicator

[J_man]

Hi,

I would like to have a sound indicator for an analog signal.

I have a detecor which generates an voltage signal and I would like to indicate the strength of the signal with a sound.

Low signal menas a low frequency sound and a high signal means a high frequency sound.

Any hints ?

You mention strength of signal one place and frequency of the signal another. Strength is usually associated with an amplitude such as voltage or current or power rather than frequency. Can you clarify what you want?

The sound output VIs can be used to generate an audio signal through the computer's sound device. You can control the frequency, amplitude, and duration of the signals you send to the sound output. So you should be able to do what you want, once you have it well defined. It may not be a pre-packaged solution, but it should not be too difficult to write oyur own.

Dear Johnsold,

thanks for your reply. I meant frequency, sorry for the sloppy writing.

I have managed to find some code on the forum which allows me to do almost what I want.

However, it is not a continous sound. It is more like the beep.vi where one have to type the duration of the signal.

It makes a beeping sound rather then a continous one.

Maybe if I could speed things up it would sound continous but I am not sure.
