An android app that provides real-time dsp mutation options on music
Use the test bench in src/test/java/ch.zhaw.ch/ generate transformed output for comparison. Additional test files can be added in src/test/res/audio/in/. The generated output files can be found in src/test/res/audio/out/.
Any audio file that is streamed on the app is written to /Android/data/ch.zhaw.ch/files with the same name as the original file. The app releases the file only after the song has ended or another song has been selected. The written file contains the exact data that has been streamed to the phones speakers.
