I wish i knew more about audio and mixerctl on openbsd For example for some reason i hear the microphone and line-in while i'm using the computer mixerctl has some output and some input settings is there a simpler way for example any graphical interface mixer for sndio ? Also if someone knows more i would glad to learn more about audio and sndio

@"rvp"#p6819 You mean the mixerctl man page?

@"rvp"#p6870 I have a line-in cable not used at the moment.

I use a simple terminal application called cmixer. It is very basic with controls for input and output using arrow keys. There are more advanced graphical applications but I do not remember their names off the top of my head.

Just mute, or remove, the unwanted channel using mixerctl. The man-page has examples.

rvp i know how to mute it completely but if i want to just mute its playback but leave its input to be recorded ?

rvp You mean the mixerctl man page?

You've lost me, mate... I thought your line-in was interfering/getting mixed with the mic?
Post the output of: mixerctl -av

chrisfromgreece You mean the mixerctl man page?

Yes.

chrisfromgreece

rvp i muted it completely and i have no problems from what it seems it doesn't record it either

chrisfromgreece

rvp now the only thing i need is to add some noise reduction filters for my mic on the ffmpeg.

I don't understand what you mean here...

chrisfromgreece now the only thing i need is to add some noise reduction filters for my mic on the ffmpeg.

Can you make a recording/video of what this noise sounds like?

You seem to have 2 mics, a line and a line-in. Can you keep just 1 mic and mute the other 3 using mixerctl (or reduce their volumes to 0)? If that doesn't help, remove the extra input sources from inputs.mix_source and record.adc-N:N_source.

And, why does it say outputs.mic_sense=unplugged, but, the other 2 lines are sensed as plugged-in?

chrisfromgreece

rvp I
have a line-in cable not used at the moment.

For what you want to do, which is make screencasts with background music and commentary, you just need a mic as a physical input source (use a good external mic here; mute the built-in one--if present). All other inputs can be muted or disabled. (The monitor source for background music is a virtual device.)

You can also test out OBS Studio

rvp i have made a ffmpeg script and it records audio from mic and desktop combined to an audio file and same time it records video only to another file then it combines them , it takes no time and its fully syncronised thats the good part.
The problem is that i want to combine audio(mic+desktop) and video together when i want to stream it right now i can stream on youtube etc using only sound from either the mic or only from desktop using two ffmpeg command using pipe.
Must look up the ffmpeg man pages for some more information i guess i can do it if i try.
For the time streaming is not required

rvp

chrisfromgreece OK. How did you fix the "noise", though? (which I still haven't heard)

chrisfromgreece

rvp I'm working on it i'm waiting for my green screen for my chair if i don't get scammed .
Ffmpeg supports some noise reduction filters as i mentioned before i think.
The noise is not very very loud most of the noise was coming from line-in i will try to apply the filters and post back
The problem you know comes from the grounding of the power supply wall-plug , i use a power-strip also which i have connected too many devices , this problem is caused from bad grounding from what i searched.
Of course i need buy a microphone amplifier there's really not another way for quality audio !!!
