My Big Blue 32 Band Audio Spectrum Analyzer Lady Gaga

Awesome Music is owned by Streamline Records. SOME PEOPLE DO NOT LIKE GAGA, BUT THIS LICENSED SAMPLE WAS ALLOWED TO PLAY ON YOUTUBE. Spektra is the Ideal RTA analyzer as finally one song was allowed.

Short audio clip of Poker Face as visualized by dual PIC16F871 processors mapping 512 LEDs. This is my 2nd generation RTA; the Spektra II. This is the most accurate looking audio analyzer on the market. What you see is what you hear.

Breath release into the mic is often sexy when recorded. MP3 compressed recordings sometimes miss this to reduce data bandwidth, but full bandwidth audio CD captured it; as seen here on Spektra.

Audio is mute until analyzer starts working.

Entire unit is designed to fit into a standard 8" tall rack enclosure for the display.

good times of the day

if not hard to tell

how much do you sell this miracle?

is it possible to reduce the size so that I can set it to the panel in the car?

And the last question

which supports this frequency range? 15-20Hz support? 9kHz?

difficult, if not, write to the email (dvorovii@gmail.com)

PS. sorry for my mediocre English

[gavincurtis]

@DvoroviiAS There is a small bar-graph display option. The actual display area is 2" X 14" and has 640 LEDs.

Lowest band is 15Hz and top band is 20kHz

[DvoroviiAS]

@gavincurtis hmm ... okay ... but the question of price ... and whether there is any budget option, simplified

[gavincurtis]

@DvoroviiAS @DvoroviiAS Hi, Cost is 650 for a 32 band controller board core fully assembled; without the power supply or the LED arrays.. you will have to wire up a matrix of 512 LEDs of your choice.

Please understand this is a side hobby, not a money maker. Parts are expensive, good PCBs are expensive; time to compose the software, the time to put them together correctly. Just proud to show off the achievement. Not being greedy.

I designed original Spektra as on my channel.

This is the most attractive analyzer i've ever seen Mr. Curtis. I'm planning to build a smaller one for myself. There are other ones which uses a software FFT, but i think you are using active filters for analyzing spectrum instead of FFT. Could you feed me with some technichal specifications about the filters you used. ie, the type of filters. you are using opamp 1 or 2 pole BP filters (butterworth??) i presume. if then, what is the Q-factors, gain, or op-amp type best suits for this project?

[gavincurtis]

@IAeoNI MBP filters.

[gavincurtis]

@IAeoNI MFBP Multiple feedback bandpass filters.

Very beutifull work. I am an audiophile and electronics/audio engineer. I would love to buy this in kit form. Please let me know when one will be available. I love the liquidness of the lights. They seem to be switching on and of very nicely. I guess that is because of the microprocessor. I would like to build an old school analyzer someday when I have time. I like Cartmans version of pokerface on South Park better! You can make good money selling these kits my friend.

@KayWal1981 Building up another 32 band analyzer unit for a customer right now. I will try and post a video of it visualizing AC/DC d.t. on youtube if copyright infringement does not block it.

no manchesss esta cado hingo emm emseñame como aserlooo estoy en wuauuu exito

[RayZorbackWPS]

I know you said this was a hobby, but if I were you, I'd patent the thing and give LEDGlow a call. You may get to quit your day job.

Nicely done. I would be interested in purchasing one that is professionally produced and "plug & play" ready. Good luck.

[RaLxMar]

Você pode fazer um para mim quanto ficaria ?

[st9v8hotrod]

hi if you sell these could you contact me or if you could tell me what you need to build one thanks

[0GSystem]

this is great, is there a guide on how to build this? I would love to have this in my studio!

I'm wanting to make a curtain with tri-color RGB LEDs. The project would use LED 1440 RGB tri-color or 30 rows x 48 columns. I wish, if possible, you rode in on a project in this style and send the value of the total project and the necessary equipment apart. Remembering q I want just the design and components, for I will ride it right here, eg Matrix Driver, program, LED, resistor to connect the LEDs and an outline of how to connect the LEDs. My intention is to display images on the curtain.

[kpopRC]

lady gaga? really?

[DJacDIGITAL]

DO U HAVE THESE FOR SALE???????? I WOULD BUY THIS! EMAIL ME @ JPETE822362@YAHOO.COM

[moefis]

@DAmoreEngineering

can you make it like this one for full produktion

[blistic3000]

Where can I get one
