I have a Macbook Pro 2012 and a pair of headphones (without their own sound volume adjuster). These headphones are awfully loud and even with quarter bar sound level, I have to turn the audio volume slider in apps all the way down to get a decent volume level. My ears aren't super sensitive or anything, I think it's just these headphones. Is there a software that I can download which will act as a virtual cable type thing where the app will feed audio data to the virtual cable (VC), the VC will then allow me to edit the sound (in my case I want to alter volume levels) and then output to my headphones.
This isn't something that you can do in the default Mac OS (I don't think so anyhow). I'm asking if anyone has heard of something like that.
