Hi James,

I just manually compiled it using javac, then ran it through the jar command. There’s a build.sh script with with source code for compiling it – which I think contains an obfuscation step too.

In principle you could adapt this to work on mobile – assuming you can access the microphone. However this really isn’t a very efficient way of pitch detection. For that you probably need to look at something like the “Fast Fourier Transform”, but that’s quite a bit more complex.

I’m new to java, what did you use to compile the jar program?
Also would this work on a mobile, this is my eventual aim.

Thanks

Hi Kadir,

there is an artificial delay that I introduced to stop the app chewing up 100% CPU, so maybe start by removing/reducing that. Look at line 241 in GT.java and you should see a call to Thread.sleep() being passed a value of 250ms (quarter of a second).

Hi John,

i am doing a project for my studies and i needed some code to get the frequency out of the mic. so i found your tuner which helped me a lot, but there’s one little thing i have to get rid of though: theres always a delay of about half a second. could you tell me how i could do that. i can send you my project if it helps. thanks in advance

@corly – I wouldn’t worry about the size too much. Your tuner seemed to load up fast enough. Though, as yours is in Flash you’ll need to wait for the latest version to come out. At the moment the current version can’t access the microphone, but that’s set to change with the new version.
