I think convolution filters are perhaps best used with headphones than anywhere else.
Easier perhaps because you can use filters already created for most headphone models but equally applicable for room correction and other primarily audio production use cases.
See this:
The Basics of Convolution in Audio Production (izotope.com)
A convolution filter merely allows one to digitally impose one signal upon another over a chosen frequency range. In case of room correction, the signal imposed is that created to compensate for room acoustics across the entire frequency range that human ears hear.
In the case of room correction, each room is unique and requires a custom filter be created somehow.
Here is the recipe I plan to follow to do it with Roon. For this in addition to Roon you just need a suitable microphone and to download some freeware. I’m hoping the mike I bought for $139 will be one the best investments ever for my sound at home and save me a lot of time and money potentially twiddling with components otherwise.
