Also, there is already simple command line program included in V8Power Tools
that can perform this task and a little more.
vpcspkr — https://github.com/LoopZ/V8Power/blob/master/README.md#vpcspkr-hzms
<https://github.com/LoopZ/V8Power/blob/master/README.md#vpcspkr-hzms>
It will also do multiple items, something like (hz:ms):
vpcspkr 200:200 0:50 300:200 0 100:500 0
