DetectionAPI supports mono Wav only

I am working on a clap detection android app. i am using musicg api for this.

I imported the project from github and run on android device. then this error shows - DetectionAPI supports mono Wav only

the detail LogCat is-

DetectionAPI supports mono Wav only
java.lang.NullPointerException: Attempt to invoke virtual method 'int com.musicg.wave.WaveHeader.getBitsPerSample()' on a null object reference
at com.musicg.api.DetectionApi.isSpecificSound(DetectionApi.java:80)

at com.musicg.demo.android.DetectorThread.run(DetectorThread.java:106)
at java.lang.Thread.run(Thread.java:818)

Do anyone have any suggestion how to solve this ?

supports mono Wav only

You should record as a wav file as api mentioned. I would recommend you to check musicg_android_demo sources.
