Full Version: a gadget that "improves audio clarity and lessen hearing fatigue&

hi, I just found some info on a new audio gadget:

http://intunition.com/tech/tech.html

So what do you think of this?

Can it really do what it claims?

Digital encoding schemes like MP3, AAC and satellite radio produce unnecessary digital artifacts hidden in the sound waves, and prolonged exposure even at low volumes can be damaging to the ear’s internal hearing mechanism.


This is what everyone knows, digital audio is bad!!! It is unnatural!!! It is harmful!!! Vinyl is what we need!

I think this is a compressor so reducing the dynamic range and maybe some high off filtering. So it probably does something audible. If the effect is strong, this might be the ultimate gadget to get AM-radio sound from your iPod.
A better way to cure hearing fatigue is to shut the damn thing off.

Clari-fi's VVCE is specifically designed to operate within the voltage and impedance constraints of the MP3 player market.
This is the sort of language which makes me wonder about this thing's legitimacy - using technical terms like "impedence" where they convey no information whatsoever. Sure, this does mean something - but not a whole lot more than "it doesn't catch fire when you plug it in". Any decent audio device will be designed "to operate within the voltage and impedance constraints" of the required application.
QUOTE
The device employs a new technology that uses semiconductor chips to miniaturize, and drive down the cost of, accomplishing a similar type of audio compression to what previously could only be done with vacuum tubes.
Wow! Semiconductor chips! That would have been really cutting edge in the 70s.
QUOTE
At the heart of the clari-fi is a semiconductor chip featuring new voltage variable compression element (VVCE) technology. VVCE technology allows for real-time, compression of MP3, AAC & satellite radio signals, removing harmful digital artifacts and spikiness, while remaining faithful to the music's original recorded tonal quality and dynamic range.
So it compresses peaks, but doesn't change the music's dynamic range? Does it also reduce the amount of fuel your car uses without changing it's fuel consumption?
QUOTE
Additionally, VVCE technology is passive (powered by the audio signal), requiring no batteries for operation and having no negative effect on an MP3 player's battery life.
Ok, that's interesting.
QUOTE
Distortion resulting from digital encoding produces what is commonly referred to “spiky-ness” in the audio.
Does it? That's not something that I have noticed in MP3 files - but I might be wrong.
LANjackal
Utter nonsense. Avoid.

any audio 'commercial' that talks about it's aging founder is smelly by default, that's what i noticed anyway. (i bet version 2 of this device will have the ability to improve AAC edginess as well, but then you will have to upgrade...)

I found this one to be more creative than "Creative" tongue.gif

At least, they don't use graph.

I'm sure that the thing will do something but what does it do? well, who know..
DVDdoug
Just what we need... A few more dB of compression. crying.gif Actually, this is likely to increase "listening fatigue".

Here's a 'gadget' I use to improve audio clarity and lessen hearing fatigue:

Hehehe. Nothing beats a good night's sleep wink.gif
WonderSlug
Hmm... there's an available downloadable PDF review on that site, from a guy at SlashGear where the reviewer claims it actually improves the sound. He said he even noticed a difference (read: improvement) when using it with his iPod and 320 kbps MP3s.


EDIT: Anyone care to try it for 30 days free as offered on the site? wink.gif
smok3
well, ask her;

she seems happy, obviously it works.

I love this sort of thing, fair play to people extracting money out of idiots.

It's not the encoding: they listen to over-compressed pop rock. After 30 minutes of listening to Franz Ferdinand, I get hearing fatigue too. Compressing dynamic range further certainly won't help.

high-amplitude excursions of MP3 reconstruction are progressively restrained with a parasitic compression function, so that the waveform modification does not produce secondary artifacts

They bargain that once you realize that this sentence does not make sense, you'll blame your own lack of understanding.

It reads like a tube-amp, or LP simulator.

I'm taking no position on value. If there is any difference in the output, we're in preference-land.

If a person says to me that they like vinyl and knows that it adds BS to the sound, that is fine with me, it is a preferred thing, but then they say that it is truer, that is when I have problems.

Digital waves are like, totally jagged, and they can cut your eardrums.

Turning the volume down will do more to prevent listening fatigue than just about anything.
mrbruno
well in fact if it is a compressor, it can be useful.
For some podcasts (talkshows), it could help to keep the overall
volume more stable.
I mean, when some people talk too loud
or soft and this device could make it all at the same volume.
probedb
Hmm, I've emailed them asking for more info....no reply amusingly enough!

I'm gonna ask how much money there is in something like this, good little earner I reckon

there are no software DSPs for IPODs?

The problem with compressors is that they add harmonics, which is distortion, which seems to kill the whole idea of high fidelity. The problem with a lot of popular music today is that it is compressed already.

Slipstreem
Whether or not the harmonics generated are a problem to the listener is going to depend upon the 'flavour' of the harmonics to a large extent though. If the harmonic distortion is predominantly even harmonics then the ears and brain perceive it as harmonious distortion as opposed to dissonant distortion, if you get my meaning.

This is pure conjecture, but I'm beginning to wonder if the advertised device is removing or attenuating original high-frequency content from the 'offending' MP3 and then replacing it with an artificially generated 2nd-harmonic distortion which could, in theory, be cleaner (ie, less distorted when compared to a pure sinewave) than the original HF content.

I'm not defending the deliberate introduction of any form of distortion as it's a perversion of the original signal, but, not all forms of distortion are equally unpleasant or equally intolerable. smile.gif

I more then understand this on distortions not being equal, but it is false advertisement if nothing else. It adds sound Quantity, not, improves sound Quality.

"Possibly improved perceived sound quality" would have been my way of phrasing it in the advertising literature. Not quite so catchy for the numpties who buy into this kind of stuff though, is it? tongue.gif

a device which could add sidebands, compression and tiny distortion
like an analog tape machine would be fine...
