MT-101: Decoupling Techniques - Analog Devices
https://www.analog.com/media/en/training-seminars/tutorials/MT-101.pdf
zThe purpose of this capacitor is to short the high frequency noise away from the chip. All decoupling capacitors should connect to a large area low impedance ground plane through a via or short trace to minimize inductance. Optionally a small ferrite bead in series with the supply pin. zLocalizes the noise in the system.
Power supply decoupling & audio signal filtering for …

The solution is to add two ceramic capacitors to the filter, one immediately adjacent to the power supply pin (C12 and C13 in Figure 2), and the other between the pin and the bulk electrolytic capacitor (C11 and C14 in Figure 2). Capacitor C12 (or C13) is chosen to be very small to pro-vide a short time constant and, consequently, the available

Decoupling capacitors are used in electronic circuits as energy reservoirs to prevent quick voltage changes. Bypassing capacitors clean DC signals by shunting unwanted AC components to ground. A capacitor significantly determines the performance, lifetime, and reliability of an electronic circuit.

The purpose of the 1uF capacitor is to decouple the output of the amplifier from the noise from the power supply. Without this capacitor, it is possible low frequency noise from the power supplywill propagate through the system. Since this capacitor is for decoupling low frequencies it should be rather large, on the order of 1 uF - 10 uF.
Op-amp decoupling - best practice? | diyAudio

"The essential requirement is that the positive and negative rails should be decoupled with a 100 nF capacitor between them, at a distance of not more than a few millimeters from the op-amp; normally one such capacitor is …
How (Not) to Decouple High-Speed Operational …
https://www.ti.com/lit/an/sloa069/sloa069.pdf
When a capacitor is used for decoupling, it is connected as a shunt element to carry RF energy from a specific point in a circuit, away from a circuit power pin, and to ground. Ideally, the impedance of the capacitor to ground should appear as low as possible to the RF energy that needs to be rejected.

When decoupling op-amps, it is good practice (and design) to use both a small capacitance value (with as short a board trace as you can) as well as a larger bulk capacitance (traces not as critical). These capacitors serve to filter/smooth out/reduce high frequency (small caps) and low frequency (big caps) noise.
Coupling Capacitors
https://sound-au.com/articles/coupling-caps.htm
2.0 - Coupling Capacitors. The purpose of a coupling cap is to pass the wanted audio (AC) signal, while blocking any DC from preceding stages or source components. DC will cause pots to become noisy (scratching noises when operate), and cause relatively loud clicks when (if) muting relays or similar are used.
