Comparing sound files? Anyone that would like to help with a sort of voice verification program, please post.

I was actually thinking of writing a program like this recently so I'm interested

Cool, post your ideas and I will compare with mine. I will post mine too.Here are a few:

01] It would take input from microphone (duh).
02] The file would then be saved to a temp file.
03] After the file was saved, it would be compared to a previously saved file.

** This is where the trouble comes in. Being able to make it give a little slack, because you don't talk the same tone every time. **

04] If maybe the file similarity was 95% or higher, it could be considered a match.

Post your ideas.

Your ideas mirror mine almost exactly!! I guess great minds do think alike. I've been trying to figure out an algorithm that would detect a little change in the voice, that's waht's going to prove the largest challenge. Well, in an 8-bit wave file each data piece is byte sized so I guess you could say if the byte was 10 off it might still work. That's my theory, if you have a better one please post it. [addsig]

No, that is better than what I had.. NOTHING. I will search around for some code that has to do with "disecting" wav/sound files.

I already know how to do that, and I have successfully done it too so we can get right down to the heart of it [addsig]

Oh, good. Well, e-mail me the code that you have so far, and we will go from there.

Geez, I hope I kept the code Will do [addsig]

^^^ what is that????? i think you need something new and innovative ^^^

It was something Wedge said in some Star Wars book that I thought was funny, so I altered it and made it my signature. It's really supposed to say "When I got Crescent, I could have flown without thrusters and shot down TIE Interceptors just by spitting at them." And getting back to the topic, I found my wave hacking program. I refined it and will send it to you soon. [addsig]

Oh, gotcha. I will be waiting for it.

Don't expect it till the weekend. Since my computer lacks a disk drive, I have to drag it out and do a direct cable network to copy stuff to this one, and I hate doing that. [addsig]

Direct cable network? Do you know what you are talking about? Perhaps you mean direct serial connection... or just a straight-thru connecting two computers.. anyways, just get it to me as soon as you can.

It really is a network, but it's officially called direct cable connection. I use parallel to do it. [addsig]

It is Friday night, so I am assuming you will get it to me tomorrow... righT?

I'll get it to you today. Probably tonight. Be looking for it. [addsig]

Waiting... it is 10pm your time.. where is it?

Sorry, I forgot (looooooonnngggg day). I WILL GET IT TO YOU TODAY. That's a promise. [addsig]

Okay... you better. It is 1.31 there and I am waiting..............................

Tick tock tick tock... 4.51 your time.........

dxProg: Do you have any ideas at all on how to do this? The reason I posted the '?' is because I don't, so if you don't I will just give it up.

I thought I said about how to do that in my e-mail. Something like this:

Dim bytOriginal(), bytCompare()

You load the two waves into these arrays, after redimming them of course. Then you filter out all the blank values, values between 0 and 5. This will leave you with the actual voice. You redim both arrays to whichever is smallest so there won't be an error when running the loop. The you run an if statement like:

If bytCompare(i) =--> bytOriginal(i) - 5 Or bytCompare(i) [addsig]

Whatever dude, whatever.
