How to avoid a electrolytic capacitor on a (audio) signal ...
https://electronics.stackexchange.com/questions/391775/how-to-avoid-a-electrolytic-capacitor-on-a-audio-signal-path
I've built a compressor basing on the all-in-one chip THAT4301. It works well. But I'm still not happy because of the electrolytic capacitor I used in the signal path. My design was based on the reference design of THAT corporation: The capacitor above is a polarized type. The signal is not biased before. As far as I know, this is a bad use.

If you have about the same potential at both ends of an electrolytic capacitor, you turn it either way and use the effect that an electrolytic capacitor can be biased with around 1V the "wrong way" without damage. Better is to use a bi-polar (non polarized) audio capacitor, in particular if it is in the signal path.

Electrolytic capacitors are generally the best performing for this purpose. They are very linear when biased by the Common Mode voltages present in most SigmaDSP audio paths and their low ESR (Equivalent Series Resistance) makes them attractive as an 'invisible' component when designing a circuit.
Audiophile Grade Capacitors

Back to those evil electrolytic capacitors: Electrolytics in the power supply need the same attention as signal path capacitors. The power supply is actually part of the signal path, even though we tend to consider it as a “separate circuit,” and the caps used there can cause the same types of distortion.

Read somewhere that if you are going to replace a 10uF electrolytic capacitor in the signal path with a film cap you can do it with a1uF PET, as a thumb rule. What if the cap is bi-polar, does the same thumb rule apply?

Even a new electrolytic cap allows a considerable amount of current across the plates; this makes them less than ideal for audio signal path usage. You can replace the electrolytics in your amplification stages with film capacitors; as I said above, doing so might improve your sound, or not.

On the flip side, it is important that a capacitor in the signal path not have voltage-dependent capacitance (some ceramics are a bad choice for this reason) whereas in a power supply this aspect is unimportant provided the capacitance …
polarized caps in audio path? | All About Circuits
https://forum.allaboutcircuits.com/threads/polarized-caps-in-audio-path.102559/
One difference between electrolytic (polarised) and non polarised capacitors is thier relatively high leakage which leads to pops and other noise. This is not necessarily an 'in audio path' effect but due to charging and discharging of the cap through the leakage resistance. The effect gets worse with the age of the capacitors and their life history.
High End Audio - Electrolytic capacitors
http://tech.juaneda.com/en/articles/electrolyticcapacitors.html
Standard capacitors (like Sprague) still good choice for standard audio devices. It sounds better than inadequate low ESR capacitors. This test confirms good reputation of Panasonic FC. It is the best no-audio grade capacitors. Audio grade capacitor (Elna, Black Gate) sounds better than all over. Theses devices are designed for high end audio.
