Ok situation, a character has Mk 4 cybereyes installed is the Eye Laser Microphone, said character has cyber ears Mk 4 with all the audio goodies, audio link and video links are installed.

Can the character use the eye laser microphone to pick up a conversation ongoing inside a room via the window glass and use the cyber ear audio enhancements to clean up and/or enhance the signal from the eye laser microphone?

Sure, sounds reasonable.

Dangerous ground using the pre-built characters as support for a position ;p

that said yeah, it sounds totally reasonable - the character has hardware for enhancing audio. If you wanted to be a total hard-ass you could raise the threshold of the cyber-technology test for implantation by 1 for installing extra wiring.

I actually would have to argue NO, or at least add some caveats. For example, "audio enhancement" extends the frequency range of hearing; this at least partly requires a HARWARE improvement. You can't boost the frequency range via digital post processing in the ears if its not there in the signal picked up by the laser mike in the first place. Similarly, you couldn't listen to a recording made with a stock comlink and gain the (full) benefits of (all of) your hearing mods.

The alternative is obvious; stuff the needed mods into the laser mike itself.

A laser mic will reliably pick up any frequency greater than its own, assuming the amplitude is great enough. Any cutoff comes from digital signal processing, which sets cut offs for anti-aliasing, and to avoid processing unneeded information (i.e. frequencies beyond human hearing). If you send raw mic data to your ears for processing, the resolution is probably limited only by how much of an expanded range your cyber ears give you.

Jot down one more vote for "resonable", please. He who brings food to the table might even convince me to use video enhancement instead.

Catharz Godfoot - I doubt even a very good laser mike has as good response as modified ears are built with. It essentially uses a window pane or other surface as a the mike diaphram, because that is what it really looks at- vibrations of surfaces. You probably get a hideous amount of low frequency noise, and a really strong roll-off at the high end. The quality of the mike and processing circuitry would be somewhat irrelevant- you are recording vibration in a window frame (or whatever).

But I suppose most of that should be accounted for in the mods for using a laser mike to begin with, regardless of other factors.

Anything that enhances hearing "quality" rather than bandwith enhancement should work by removing background clutter (by making sense of it). So the sound source should not make much of a difference.

Ok more details are needed I feel

Cyber Ears Rating 4
Audio Enhancer 3
Increased Sensitivity
Select Sound Filter 4

Note increased sensitivity that brings the cyberears "listening" range from ultrasonic to infrasonic ranges.

Audio enhancement allows user to receive a broader spectrum of audio frequencies(including those outside the normal range of hearing).

Selective sound filter allows user to block out background noise and focus on specific sounds like a conversation.

To me this cyberear package can process the sound? data from the eye laser microphone very easily.

Your eye laser can pick up the sound fine, but unless you have a speaker around for playback to your cyberears, then you're just hearing it in your head. Pick up an edit program, and edit your sound that way instead. I say this because cyberears are made to process the sound as they hear it, not as it comes in from the laser mic. The laser mic sends the info it got to your brain via DNI. Your cyberears never hear any of it. So, either record it and play it back through a speaker to your ears (thus letting them process it) or get an edit program and do it yourself.


Audio enhancement doesn't increase frequencies, thats what increased sensitivity does. Enhancement just makes your hearing better, clearer, etc, however you'd like to describe it. But someone with just audio enhancement can't hear any new sound frequencies that they couldn't before.

or . . you know . . wire it so the sound actually passes the ears so they can give you the filtered sound and it can be stored in the recording unit that ears come with, if i remember correctly? O.o

And how would the sound pass by the ears? Its a data signal from the eye laser mic processing being sent. Your cyber ears edit what they hear. Since no actual sound was made, they can't hear it, so how can they edit it?

If you apply the conventional logic of audio signal reception and processing, cyberears would be something like

Microphone -> Digital Converter -> DSPs (Digital Signal Processers-> Neural Interface.

So logically (logically mind) in the SR world of unlimited interconnectivity, you could easily substitute the ear mics for the laser mic.

Laser Microphone -> Digital Converter -> DSPs -> Neural Interface.

Cthuludreams- your right. The question is, is the laser mike feeding an comperable signal to the digital converter as a set of ear mikes (from ears with all the propper mods) would?

cyberears have a sound link. you can pipe the sound through said sound link. the ears can (presumably) hear that sound link.

The signal processing has to be pretty heavy-duty already. Every heartbeat is going to interfere with that signal. Every microsaccade., every breath, and every involuntary twitch is going to muddle it. It's not like you're using a laser on a tripod or something.

So once you get signal processing good enough to distinguish in real time between window vibration and your cheek twitching from all the Jazz you took, you're into the realm of 'sufficiently advanced technology' anyway.

I agree with Catharz, the laser mic is made of magic as is, because you cannot hold your head still enough for it to work.

Personally if you asked me the same question I'm not sure what I'd say. Another poser: Can I record sound and hand it off to someone else with mods later for a better analysis?

I'd be tempted to say yes but its a tricky question.

@Tarantula
BBB page 324 yes it does (Audio Enhancement) gives you broader spectrum of audio frequencies including the ones outside the normal audio spectrum. And yes so does increased sensitivity. :)

Pathway could always be, cybereye laser mike, to cyber ears via the much ballywhoed wireless link. :)

You're right WMS. Audio enhancement to me means you would hear all possible sounds for the human ear to hear. An example is that as children humans have a higher frequency range than as adults. With audio enhancement, you would be able to hear those ranges.

With increased sensitivity, it explicitly is ultrasonic and infrasonic sound, which are beyond regular high and low frequencies.

As far as the magic eye laser mic, maybe the cybereye is able to move minutely inside of the socket to correct for the minor vibrations caused by breathing/heartbeats etc.

Hmm, I could have swore that it was clarified in the monster "Ask the Devs about AUG" Thread that there really wasn't any reason to get both Hearing Enhancement and Aug's Increased Sensitivity because Hearing Enhancement already had it covered.
