the power of software?

panabox - 2010-07-05 08:57

I was just listening to itunes on my computer and had it playing thru my panasonic rx-dt680. I adjusted the equalizer on itunes to fit my preference ( namely the 32hz freq up to the max). It sounded good playing thru my 680. It got me to thinking:
how is it that an eq software can give off the same effect as an actual eq (hardware) with heat sinks, capacitors, amps, etc? If I was able to enhance the sound that easily without the addition of any actual amps, equalizers, or power upgrades, how hard is it for engineers of boombox's to better a box's sound by merely adding aditional software such as an eq? It seems like a simple upgrade with extraordinary results.

good thinking PANABOX, maybe radio techs will add this feature to future boomboxes, who knows??
but i gotta say, would it really make a difference these days with the shaddy workmanship and the ugly very low wattage boxes that we see churned out today.
in my opinion NO it would,nt, technology on radios was lost somewhere back in the 80,s/90,s and i gotta say, there,s nothing like the feel of the material when adjusting sound.
even if this feature was to be added to future boxes i don,t think it would appeal to any of us guys who love our old skool boxes.
personally it would,nt bother me if the feature was ever added to new boxes, because i would never buy one No No
having said all this, i do see your point Nod Yes Wink

Perhaps it could be made available on only the high end models from the manufacturers that have proven their products over the years: panasonic, jvc, phillips, etc. All box's don't have to be low wattage. And if power consumption is an issue, then adding software as oppose to hardware seems like the way to go. You get the sound, the power, and the bass without a single piece of added hardware.

ye i see what you mean here Nod Yes also it,s deffinetly the way forward in terms of going green Nod Yes why don,t you apply for a job at one of the above mentioned manufacturers Big Grin seems like you got the tech brain Wink

lol. the only thing i have are ideas. I wish I had the tech brain. lol

In software, such as an "equalizer" function in audio-editing software, where the audio is a string of numbers instead of an electrical signal, it's done mathematically, with Fast-Fourier analysis for example. For MP3s and most other similar formats, it'll have already been split into a bunch of pass-bands when it was originally encoded, and will be stored in the file as separate pass-bands, in which case it becomes trivial: just change the levels of the pass-bands during playback before they're recompiled into the output audio, add an interface and you're set. The interface is probably the clinker though: do you want to have to surf around with buttons to change an EQ band, and probably have to select and change them one at a time? Most manufacturers aren't likely to want to add a bunch of slider-encoders, except for a very high-end box maybe. But some cool things would be possible, like a "paragraphic" EQ, or specifying as few or many bands as you want.

I thinks the mathematics should be done when designing the product, not in post processing of the sound signal. But no doubt, eq:ing and fiddling with the sound makes a poor product sound better...

Add to that the cost of a computer powerful enough to model the electronics of any eq or amplifier... maybe it is not just worth it. Very interesting idea though... Smile

And there IS good quality audio equipment nowadays too... for example Tivoli Audio and Tangent Audio. Brought home this week a Tangent Quattro MK2. Just 5 watt RMS and no audio adjustments other than volume and sounds nice as hell!

i have a sony NWZ-A818,8GB mp3/mp4 player,its got the best eq and stuff i've ever had,it has 3 stage "clear bass setting" like loudness..it also has a 5 band EQ,and i can adjust each band seperately..its also got surround sound,it sounds awsom on my philips headphones..

I was at walmart yesterday and was reading in Mac World magazine about a new app for the iphone called Amplitube. It's simulates a real guitar amp all through the power of software. Imagine the endless possibilities if this technology entered the world of boomboxes. Imagine being able to hav a 100 watt rms boombox that can still run off of batteries. Inside you won't find the usual hardware found within boomboxes, you;ll only find circuit boards.
It's like the time we went from vacuum tubes to capacitors.

okay. For the past couple of days I've been imaginig a future boombox by Panasonic. It looks like the RX-DT75 only bigger - about the size of the rx-c100 and thats with the top panel closed. It's even bigger with the top open. Imagine this guys: in the back panel sits two subwoofers built into the panel itself. It would resemble the Bob Carver sunfire. sunfire with their own air tight compartment having a freq response as low as 6 hz.
In front of that panel would be two mid bass drivers also having their own compartment. In front of that would be the front panel which houses the tweeters and the squakers. I would like for the squakers to be able to produce the warmest of sounds super loudly with zero distortion. I've never heard the surround sound of the dt 707 but others have said it's good. I'd like for this boombox to have that plus multiple ambience settings ( concert hall, stadium etc) heck lets throw in 7.1 surround. The top panel would be a coumpter screen that houses itunes, wifi indicators, the equalizer, the visual spectrum all sorts of goodies.
The finish would be an elegant black piano finish with silver accents around the speaker rims. What a box! It could be called the "ibox" by Panasonic with the lighted apple logo on the top panel ( similar to where the camerea is located on most laptops). Panasoninc needs to shake hands with Apple and build this monster of a box (egg). It would be the ultimate audiophile's studio all in one. There's many other features that I have in mind but just don't feel like typing a book.
Powering it all would be nothing more than software. The power of software! Just imagine the possibilities.
Just my 2cents of an imagination...

Umm... but you still need a real hardware amplifier to produce the sound! A digital sound projector like the Yamaha YSP series would do the surround trick in one box if it is really necessary. Music is best in >>>>STEREO<<<<...

would a sound card work?
how does a laptop produce sound via headphones - is there an amplifier somewhere?
