Comment The Analog Hole Is Uncloseable (Score 2, Insightful) 275
When will people learn that this is impossible? How is the broadcast going to play if there is no "analog" output? Sure, they can disable the line-out jack or whatever, but given the mere fact that the broadcast is audible we can deduce that:
1. A transducer is converting electrical energy into acoustic energy (almost certainly by driving a speaker cone)
2. Said acoustic energy (Sound) is an "analog" phenomenon. The compressions and rarefactions in the air that carry sound are continuous phenomena, there are no jump discontinuities in sound pressure, all sound is analog both in theory, and for all the sounds that we use to communicate or make music etc, in practice.
3. Thus, said transducer is being fed an analog electrical signal somehow (digital to analog conversion is beyond the scope of a transducer, they expect an analog voltage input, typically provided by a DAC somewhere in the hardware path between the CPU and the speaker)
4. Therefore, no matter what type of software bullshit protections there are, if I can hear it, I can record it in HIGH FIDELITY by simply ripping my speaker cone off, and connecting the former speaker input +/- to the line-in jack of my laptop or whatever.
I take for granted that most of you already know how obviously easy it is to obtain a recording in low fidelity: use another transducer, i.e. put a microphone in front of your speaker.
So what's the deal with the MPAA? The government? And any other group of morons who keep trying to defy physics by making media that can be played multiple times but not recorded? There is no such thing as DRM short of installing chips in everyone's brain.
