Hello, I need to increase my microphone sound volume above default KDE 150% ( I have Audio-Technica high-quality microphone and Asus Xonar Essence STX II soundcard, but their recording sound volume is low).
Previous KDE versions allowed to increase volume only up to 125%. And currently it’s 150%. I think it’s possible to make 200%. So, I think somewhere in configs should be an option to increase to 200% https://i.imgur.com/dSo8VTp.png
This is my alsamixer view: it is not possible to increase the volume even to 150% if it’s not available from Plasma settings before. So, I think it’s not the case to use alsamixer for my case. Also it doesn’t save the settings after reboot (according to forums). https://i.imgur.com/2PgdSOM.png
I have perfectly clear sound even if add 10db in Audacity. So, noise is not the problem. Just need to add 5-10 dbs
Replace battery, try another microphone.
You need additional power for Condenser Microphone.
The PRO 24-CM camcorder microphone…
The microphone is designed for either battery operation or battery-free operation when used with camcorders that provide plug-in power at the mic input.
Stereo microphone designed to attach to a camcorder
For camcorders with an accessory shoe and stereo microphone input
What about using hardware the right way?
You’re lowering sound quality with programmatic magnification.
You can achieve the same sound quality with a cheap microphone without additional power input.
Yeah, thanks! There is no option to use up key but M added +20dbs to the volume. Think, I also need to save this settings (at least to make a script) to use them after reboot.
Yeah, adding +20 db added some noise. But my mic costs $99 while I bought it half a price somehow. Need to check if there a possibility to use a better battery, because I don’t want to add something with a size of UPS to my mini-PC.
Disabled HDA in BIOS and it feel the sound became slightly better (maybe not). No need to restart alsamixer every time, so mission seems completed. Maybe some hardware issues like extra power and mic stance will be solved later.
Every condenser microphone needs power to operate. Plain and simple. How much power, and where that power comes from, depends on what kind of mic you are using. When it comes to using a video mic, there are three main power sources that will provide the juice it needs: your camera (called ‘plug-in power’), batteries, or what is known as ‘phantom power’. The type of power your mic uses will depend on its size, features, and capabilities. Let’s take a look at the differences between the three.
