echoprint codegen for Java/Android

Question

Is there a way to run the echoprint-codegen on Android or is there a Java implementation for it?

Echoprint codegen on github: https://github.com/echonest/echoprint-codegen

There is a C++ implementation for it? I just cannot figure out how to port it to Java so that I can run it on an Android device, assuming Android 2.2 and up.

Answer 1

Take a look at Alex Restrepo's port of Echoprint to Android. His blog posting with the technical details is here:

The complete code along with a sample Android application using it can be found here:

Answer 2

Try this open source project by Jacquet Wong, it's written in Java and Android compatible.

http://code.google.com/p/musicg/

It handles wave spectrogram, fingeprint and other audio features with FFT and other dsp algorithms.

Answer 3

There are java libraries to deal with FFT / Audio which may already do what you need. Ropy van Rijn already did this, and got slap from Shazam patent holders.
