DetectionAPI supports mono Wav only

2020-05-03 09:34发布


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(
at com.musicg.api.WhistleApi.isWhistle(

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.
