Apps Hi! Please help me develop an acoustic guitar tuner for android phones

[Esther Ann]

HI! I'm new to android programming and needs to finish a project on frequency detection for android chromatic guitar tuner. Any idea please. I have already prepared the UI for the app, and I was able to finish the manual tuner. I'm now working on the automatic tuner portion of the application.

Thanks!

You need to find a realtime digital signal processing library or make one on your own i can't help you more cause this isn't an easy thing for me

Thanks ThanosF. I hope someone can help me too. I would like to use FFT for for analyzing the sound frequency.

Then have a look at libgdx project. Its a game development framework but it has extensions like gdx-audio.jar which can perform FFT calculations check the source code here and see if it fits your purpose
