Never mind, it's my fault! I'm very sorry!
I didn't seen that the two Y scale are different!!

I've take a look to boost::pool, tell me if I understand well.
I have to allocate contiguous memory to store a recorded audio samples.
So, is legal to do something like this:

//Allocate chunks of 65535 bytes
boost::pool<> p(65535);
//Allocate 100*65535 bytes of contiguous chunks
void * pMem = p.ordered_malloc(100)

Now, assumes that I have a function like:

void MyMemoryObj::Write(long pData, long byte_to_write)
{
  // In windows I write the data pointed to pData into the buffer with:
  RtlMoveMemory pMem, pData, byte_to_write
}

Is there a way to copy memory in boost?

Thanks,
Daniele.
