The capacitors that are used in the high-impedance parts of condenser microphones also need to be low-leakage, as they have to work with 1 Gohm to 10 Gohm bias resistors. I think those are usually plain old MKT capacitors, but it's been a while since I last opened up a condenser mike.

Low Leakage: An ideal capacitor doesn’t have any electrical connection between the plates, so there would be zero DC current across the capacitor. This is not an ideal world, and so real capacitors do leak DC. The formula given in the spec sheets is of the form: Leakage current = Constant * Capacitance * Voltage,
What is Capacitor Leakage Current and How to Reduce It

The leakage current of capacitor is a crucial factor for the application, especially if used in Power electronics or Audio Electronics. Different types of capacitors provide different leakage current ratings. Apart from selecting the perfect capacitor with proper leakage, circuit should also have the ability to control the leakage current.

Low volume, strange sound or hum in the audio output – these are symptoms of aged or leaked electrolyte capacitors. Electrolyte from capacitors can cause severe damage, sometimes unrecoverable. Electrolyte causes corrosion of copper traces. Result can be completely eaten traces on printed circuit board, released components, etc.

Leakage is predictable and can easily be distinguished from DA. For example, after 100 time constants, the charging current should be 20µA/e^100=1.49e-48A. That's 100s for the 1µ, and 330s for the 3.3µ.
