Hi!
Is there any future of the analog audio sources? I mean is there any real developments in this world or the Digital is unstoppable.

If you look at the scource material out there I would say yes.
Lots of stuff that will never be released on any digital format.

Microphones will never go away as an analog source. The delay of the A/D process is not acceptable for Radio and Television. Even the shortest delay is detectable (and annoying) when wearing headphones or earpieces.
All sources of real music are ultimately analogue. The question is simply where (and whether) they get converted into digital for safe storage and propagation before they get converted back to analogue for our ears.
not really correct: it means that electronic music is fake music ?
Maybe it is...who knows ?
Ehm, umh...some controversies in my mind : when I'm singing a tune in my head...are the neurons controlled by electric impulses so I'm on digital playback mode ?
And yesterday I was on my 5 minutes " opera mode" and my voice was very charming and I could play even the vibrato ! But yesterday night I couldn't reach the higher notes of She's Leaving Home...after many years of living lone !
So today I woke up with Dr.Dre tune in my head : " If you wanna make noise, make noise..."
I hate my digital side

Then why do radio and TV in fact use digital (and have done for years)? An audio ADC need introduce no more than a few 10's of uS delay, a video ADC considerably less than that.
O.K.
Is there any research to new audio recording solutions or materials except for the well-known turntable, tape recorder or the master of the analouge sources Reel-to-reel audio tape recording?

ADC/DAC is the easy and fast bit. The hard/slow bit is coding (perceptual or lossless), interleaving and error correction which then require significant buffering. If it has to go over a radio link (e.g. broadcast, or radio mike) then FFT to/from COFDM may be needed too. The result is a significant delay.abraxalito said:
Sure - my question was asking if the A/D process was indeed 'unacceptable' as claimed why was it still in use?
I think he may have meant unacceptable for radio mike use? Or any other situation where close synchronicity is required in real-time.
That is exactly what I meant. Even the shortest delay can be quite annoying when listening to your microphone through headsets.
Can you point out one professional device that doesn't use AD conversion? I mean of this century.
On which field are you working on? What's your application that the μsec (even nsec) delay is annoying?

DPA Microphones :: Digital wireless and mics reports a delay of 3 to 5ms for a digital microphone.
Analogue radio mikes are still widely used. In the UK they were recently moved to a new frequency range, which annoyed some people.

When you say analogue, could you specify what do you mean exactly? Cause when we talk about wireless mics I honestly cannot see how it can be without any digital part.
PS: again talking about today's devices and not devices from back in the 70's.

This is about digital audio .... not digital parts in a wireless mic. An analog wireless mic might use digital circuits to synthesize the operating frequency. That does not make it a digital device. In radio and TV, analog microphones prevail.
Just like most FM tuners are analogue sources even if they use a digital chip for the local oscillator.
