It is the problem with your driver which creates this chopping effect.It is not able to read the data properly and if you check your kernel messages there would be a buffer overrun message.This happens because Linux is not RTOS and audio is running in real time.
What you are recording is noise also along with voice data.So you need noise cancellation algorithm also if you want proper sound. There is one more problem with respect to sampling rate.If your driver supports "x" sampling rate and you want to sample at "y" sampling rate then there is resampling that takes place which causes some loss in data.So your re-sampler also should be good enough to do re-sampling. Generally audio re-samplers provided by android is not of good quality and if you do playback and recording simultaneously then you can make out that playback is not proper(there would be some audio distortion in your playback audio). -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
