Take a voice note without unlocking the device

Sometimes, I want to take a voice note quickly. My ideal approach will look something like this: 1. Take the phone 2. Push a button 3. Speak a sentence (**without unlocking the device**) 4. Done Later, I want to see a list of open voice notes (not handled yet) and reply them. No speech-to-text magic is needed. The primary focus is on speed. Background: If I am talking to someone and want to take a note, I don't want to disturb the conversation since taking the phone, unlocking it, opening a note app, and finally typing it takes too long. Best solution would be this: Start recording without looking at the phone. Like a dictaphone. Anyway to get this thing get done?
