hi all When I start recording sound the data from audio hardware is right, but when the data transform to the amr encoder, alot of frames missing. If I recording sound for 8 seconds,but the amr file is only has 2 sec. The Alsa buffer allocated 16384 B in default,if we make the size is equals to the default size,the data maybe missing or the buffer maybe overflow . but if I change the size to 2048 , the amount of recording data transform to AMR encoder is larger than alsa input data . May be there are some operations in the transform process. But can some one tell me how to assign a right size to the buffer?
