Spectrogram of Violin

A pair of South Korean electrical engineers have worked out a new porn filter that analyzes audio for tell-tale signs of things you really shouldn't be watching at work. By using sound, they avoid the problem of visual porn-identifiers (pornifiers) that can get tricked by any expanse of skin, as in closeups of the face or other not-inappropriate body parts.
The engineers started by making spectrograms, basically a visual representation of a sound clip, of lots of different kinds of audio, including music, non-porn video, and porn. By analyzing these spectrograms, they figured out that pornographic audio has a few unique qualities that make it fairly easy to recognize: Regular speech is low-pitched, music has lots of different pitches, and both tend to be fairly constant. But the porn spectrograms showed a high pitch that changes often and also repeats itself.
Using this data, the engineers developed software that could identify porn correctly about 93% of the time. There were some hiccups; apparently laugh-tracked sitcoms sound like porn (weird fact!) and porn can sometimes sneak by the censors by using background music. Of course, image-recognition porn identifiers are just about as accurate and require much less time to analyze (a single frame, versus the audio identifier's need for a longer clip). But it doesn't necessarily need to be one or the other: Some see a potential to combine the audio and visual identifiers into one super-detector, a gauntlet through which no porn can pass.

Exactly how did this group of engineers developed that data base they use for comparison? I can only assume they got paid to R&D a lot of porn sounds and cross reference achieve. It must of took a lot of research!
Wouldn't that block tennis as well?!
I thought people turned off the sound!
Who- in the bloody fuck- would watch porn at work?!?
What sort of idiotic, useless asswipe has the time and luxury to piss away the day on the internet?
What kind of job even permits that? Do they not have supervisors or blocking systems? You'd think that if an establishment readily employs computers- that they'd have the ability and know-how to keep their salary men from jerking off all day.
This idea is baffling to me.
I don't see why a Government can't control content by a rating system. Why do we restrict porn at a movie theater and never even tried to allow families G rated ISP content. It is way past time. Allowing ISP's to distribute porn to children is as bad as a society can get. Hey, if you are over 18 or 21 what ever floats your boat but families have a hard enough time raising children free of TV and movie madness. Children need to be protected. They should be free to be children.
bAHAHAAHAHAH! Good stuff, good stuff.

This has epic fail written all over it.
I work for a mattress sales company and I have up to 11 hours a day to fill... sometimes I wont see or talk to anyone for 6 hours... Sometimes none all day.
I would be a liar if I said it never crossed my mind... however... I'm really going to have to say I agree with Douglas_Von_Yamoto. Pumping the Porous at work is a quick way to the unemployment line.
That being said, I don't think this is for applications at a job. It will initially to justify its existence; but where we'll see this applied is in mainland China, who, if they had their way, would never let their people have any access to the internet unless every document was redacted and monitored by them. Look at the all out WAR they are waging on Google.
Watch: They'll be using this to block porn from all users in their country within five years.
@seatellite you are probably right about them blocking porn, but i think they would probably use a visual filter it would work faster.
