Analysis of audio input in VBA

Hi all,

Hope you can help. Is there a way to analyze the input of audio through the mic-in and compare it to a standard stored either in a sheet or in a way file or database? Effectively, what I'm looking to do is compare an audio input and see if it matches a designated sound.

I found Sox online which converts wav to txt but am (a) not sure if it would work in this application, and (b) would increase processing time dramatically as I'd have to save the audio input as a way file each time.

I would ideally like to run the processing through vba code as I will be doing other operations at the same time.

Any ideas good people?
