I’ve always looked for articles about capacitors for audio, and have a few I can share.
The first is a two-part series by Walter Jung and Richard Marsh, “Picking Capacitors" in Audio Magazine, from way back in February and March, 1980.
The second is WAN_0176 from Wolfson Microelectronics, “A.C. Coupling Capacitor Selection”
The third is a short treatise on how a capacitor’s type influences dielectric absorption, "On Capacitor Dielectric Materials - A Chemist's View” by Karl A. Weber, Ph.D.
The fourth is "Signal distortion from high-K ceramic capacitors” by John Caldwell, Analog Applications Engineer, Texas Instruments - from EDN.com, June 16, 2013

They all generally rank various capacitors in audibility. It’s interesting to see the types of tests and conclusions these different authors make.
