I often have to install and test microphones. Usually, I use KRecord. It has Input level button, that I use to see if microphone captures some environment noise. Usually, I have to test microphone as silent, as possible.

Is there some tool in KDE 4 to look at microphone signal level?

kwave can do it, but it isn't the most elegant tool for the job since it is more of a sound editor.

PulseAudio Volume Meter (Capture)
PulseAudio Volume Meter (Playback)

you get these by yum installing pavumeter

the capture one just has a little meter to show you whats being captured, I dont know how precise it is for you tho

pavumeter may work, but it isn't a KDE 4 tool (it uses gtk). Further, it would only work if pavel is using pulseaudio, which he may not be (by default openSUSE's KDE installation does not use pulseaudio).

Also, since he is on openSUSE, which doesn't have yum, he would need to use zypper (for the commandline) or yast2 (for a gui tool). The application name (pavumeter) is still the same, though.

Thanks, pavumeter will help me, but I wonder if KDE does not have some native KDE's (phonon's) level meters.

Phonon volume meters would be a great feature. I think that it's a great missing in KDE.
