好像你正在尝试进行语音反转。

如果是这样，维基文章就足够了。将波形文件样本与一组正弦波样本（从+1.0到-1.0变化）混合（相乘）并过滤结果。过滤是一个独立的主题。

iam doing a project on speech encryption.. the thing is that i am stuck somewhere.. i need help on how to alter the frequency of a recorded sound using java.. changing its amplitude can also help.. I am REALLY STUCK HERE... please help me out :|.....

Seems like you are trying to do speech inversion.

If so, the wiki article covers it well enough. Mix (multiply) the wave file samples with a set of sine wave samples (that vary from +1.0 to -1.0) and filter the result. Filtering is a topic all its own.
