How to boost your microphone above the Mac OS limit

If you just bought a good mic but got dissapointed how quiet it is, this post will sort you out. My Blue Snowball iCE was way too quiet out of the box and I've used this procedure to make it sound great.

First we'll set up BlackHole, but the focus will be on Element, which is a great VST host application. It enables the manipulation of an input singnal through VST, AU and its built-in plugins. This is a good alternative to AU Lab, which actually works. We will also install AU Lab for it's plugins however.

The rest of the chain is just passing on a hot potato.

This was initially posted in an kubernetes-sigs/kustomize issue.

We are using Kustomize's vars feature. Initially we didn't understand how to use it for our purpose, but it is a 100% fit. One example is our Ingress resource, which looks like this:

# file: base/ingress.yaml
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: services

Find the key you want to change

• run xev which opens a new window
• when you type the key that you want to rebind, the terminal from which xev is run will display all the info about that key
• look for the keycode section
• gather all the keycodes this way

Rebind the key

• run xmodmap -e "keycode = " where expression is the value (Escape, Control_L, etc.)
