Re: Comparing 2 Spoken words, FFT function in LiveCode?

LC Script is probably not fast enough for performing a FFT.
But you could use, for example, the following digital signal processing
library for javascript via a browser widget.

Or try to use LCB's java-FFI based on these approaches:

Comparing 2 Spoken words, FFT function in LiveCode?

2017-10-16 Thread Peter Reid via use-livecode 
Does anyone know of an implementation of an FFT function written in LiveCode?  
I've tried joneslib but this doesn't include FFT. I'm hoping to use FFTs as 
part of my attempt to compare 2 short sound clips of people speaking a single 
word.  I'm trying to judge whether a single word spoken by 2 different people 
is the same word or not. Any advice or code that might help with this would be 
most welcome.

Thanks

Peter
