memory leaks

memcpy(static_cast<void *>(data), static_cast<void *>(data_), bytesRecorded);

This line can be wrong if compiled when char != 1.

memcpy(static_cast<void *>(data), static_cast<void *>(data_), bytesRecorded * sizeof(char));

Binary String? you mean like "01010101". Shouldn't that fit into chars? you can also cast char to unsigned char as well.

typedef basic_string<unsigned char> ustring;

I think for the moment I'll use this:

At least it looks better
