patest_in_overflow.c File Reference

Count input overflows (using paInputOverflow flag) under overloaded and normal conditions. This test uses the same method to overload the stream as does patest_out_underflow.c – it generates sine waves until the cpu load exceeds a certain level. However this test is only concerned with input and so doesn't ouput any sound. More...
