what parameters can i mention and monitor to check the quality of a sound-file created on real time.
Any framework would be so helpfull.specific for any Linux distribution.
Thanks in Advance

?????????????????

What is the purpose of your monitoring ?
How do you define sound quality ?
Why do you want to monitor file contents in real time and not the sound stream itself ?

If suppose in case the recorded sound quality coming is not good, then i gotta go for network health check and all.
so,i can not find criteria to monitor-sound-stream with built in libraries itself.
Any idea please share

I am asking you again: "How do you define sound quality ?".

yeah off-course, the criteria is not certain and that's the only thing i wanna discuss for.
i gone for research & found.let me point out
1.NOISE
2.THERSHOLD

will there be others.please discuss for both the above.
means how could be judge of "noise" and "thershold" value of existing media file.
thanks

Regarding noise. In a recorded sound how are you going to distinguish microphone amplifier noise from, say, noise present in the recording hall ?

Regarding threshold - threshold of what ?

so,what parameters would you like to suggest..

In Russian there is a saying/joke: "Пойди туда, не знаю куда, принеси то, не знаю что", and even there is an article on that in Wikipedia: https://en.wikipedia.org/wiki/Go_I_K..._Know_Not_What . It looks to me this thread of yours fits the article perfectly well.

I have no idea what you want.

Probably if you start learning stuff about signals and sound, you'll be better able to formulate the problem in a manner that makes solutions feasible.

thanks for that!!i got the meaning.
so,here i am describing:
i will record few sorts of sound in ".wav" format.
Now matter is this,if the ongoing recording quality of media-file is not good.
then i have to stop recording.
I have parameters to stop recording by sending interrupt signals to hardwares through my program.But not getting, what parameters should i monitor to check the real-time-sound-file quality.
thanks in Advance

You have so far failed to define "quality". For example, non-linear distortions of electric guitar sound may be good - if the guitar player is using the distortion effect.

OTOH, non-linear distortions of human voice most likely are not good.

Anyway, in order to measure distortions you need you need to have access to the undistorted source sound in the first place - which I guess you do not have.


Again and again, it is you you has to define what sound quality is WRT task at hand.

and what in case if i record sound from any channel.like through a call or any online media.

How else should I tell/explain you that monitoring quality is senseless until/unless quality is defined in practically measurable terms ?

To be very specific,need "voip monitoring tool" source in c-language,compatiable with gcc compiler.
and parameters i check are 1.Network delay,2.Drop,3.Jitter,4.Loss,5.Noise..
any furthur suggestions!!plz post in here.
Thanks

@niteen I wonder if JACK could help you. Perhaps with it you could redirect a copy of the audio to another monitoring server somehow.

- how do you measure network delay ? Regardless of sound. Or in the context of sound, does the protocol you are to use have provisions to measure network delay ? Anyway, if you listen to, say, sound stream playing Janis Joplin or Jimi Hendrix (IIRC both died in 1970), does it matter if their songs play 1 second later ? In other words, when does network delay matter ?

- of what ?

- of what ? And are you sure your SW doesn't take care of jitter ? Ever heard the "reclocking" word ? If not, try https://duckduckgo.com/?q=DAC+reclocking .

- of what ?

- I have already pointed your attention to difficulties distinguishing noise from signal. You think if you just repeat the "noise" word it starts making more sense ? If you have no idea how do distinguish signal from noise why are you mentioning noise in the first place ? If you have an idea, would you share it ?

Maybe before even thinking of monitoring sound quality you should first learn what sound is and also learn a number of important things on signal processing ? This is of/from "furthur suggestions" department.
