I need to build a prototype of two pieces ,
tx and rx at 2,4 - 5, 8 ghz to transmit wireless uncompressed audio , low power.
Tx and rx have to work on up to 40 stereo channel (double for diversity system),
work with rechargeable battery . The Rx have to be a SDR system .
The critical of this project is to remain under an ultralow fixed delay from source to final user.
There's a device that do this work, claiming 2,5 msec of latency, that is what we need
Is the [url removed, login to view] device, but i ignore his components.
I need to start some small production, i have some time to respect and i will pay only if the prototype will result replicable from my chinese factory and passes tests, that have sense for me , i dont know site rules..
This Tx-Rx devices are only few parts of a more complex project , if you'll do a good work, we can go further and i will ensure job for the next steps of the project and complex features involving Mirocontrollers and audio Dsp.
I don't understand if the price for this type of work is low or high , let me know some opinion.
going deep Probably will need a non disclosure agreement.
let me know
I was suggested to change the description of this work :
I have a probably winning set of products in mind, i would build ,and launch them with a crowfunding campaign , i reached some small funds to start but i have not experience.
The devices to build are more than one, and run different functions, but each of this part is a tx or an rx and his functions, start from a robust hi fi digital audio onnection without much latency.
Need a serious help to not fail, mainly an electronic developer with skills on Rf and embedded, that own too some ideas about state of art of stage pro audio and commercial products standards .
I would that developer relates to a Chinese factory*or wherever is good, to test, build a working prototype and follow production (better if already had experience and can advise one good of them).
The entire set are different fashion of a tx and an rx, at 5, 8ghz, to transmit wireless uncompressed audio 24 bit .
I could not use prebuilt modules like AWM655 or similar. they don't meet requirements, and there's no way to modify it.
I would test your solutions on this critical part, to seriously hire you for the entire project.
Follow a case, by a final utilization of this Audio connection.
In the tx ideally we break the B.F in-final antenna chain, inserting I.E. a simple audio effect, a chorus, to do this, the developer can choose the way.. but in each case will manipulate really fast data of uncompressed audio stream thru a fast circuit That act as a DSP, but have to surpass normal DPS integrated solutions, to fight Latency.
At this point we have a 5,8Ghz 48-96khz/24bit tx with a CHorus on bord. well.. how we regulate level, rate and depth of the new on board effect?
I have a solution that needs a bluetooth connection as subcarrier of the system.
If the IC the developer will choose have not an internal subcarrier, maybe useful to use bluetooth and direcly drive the "DSP" functions.
That's another way to see all the project, and is only the Transmission part.
Another explanation will need the receiver.. SDR and fast processes , to do the same thing
break the chain and insert a trigger for some DSP functions, we can need to regulate volume remotely at first. The enemy is the total latency.
To do a good product, it cannot cost a life, but as the destination is not the home consumers, we cant do magic to achieve quality. I.E. AD DA conversion aim to have superfast chips, bad converters are not suitable from studio final users and they recognize it with their ears without any measurations.... and so on.
So some other tech note: Tx and rx have to operate on up to 40 channel (double for diversity system on rx). The bands have to be selectable to cover different national laws about frequencies.
The Rx ask to be a SDR radio, here too i need to manipulate data it cannot be a commercial module.
The critical of this project is constrain the audio link, to remain under an ultralow fixed delay from source to final user.
There's a device on the market that do this work, claiming 2,5 msec of latency,
Is the stageclix. com device, i ignore his components.
Isn't my idea to build a replica , this piece is only part of the final device , that have different scope and final specifics.
Please note that i'm conscious that the price for your skill, on my offer is low, and i'm rewriting this just cause was misunderstanding about the whole project.
so i think will le go down this offer and will rewrite another one with an higher price.
in meantime i will follow your proposals.
I'm not a Company, I launched this project on different platforms and got high interest from chinese factories, but seems they don't have the know-how to project it.
The only way to develope this device is to hire smart professionals , discuss about any aspect and partecipate the project conscious that the way to pay all the production chain will need a well made Crowfunding on kickstarter.
This project is on Hwtrek. com too
