Optical isolation for audio amplifiers
https://commons.lib.niu.edu/handle/10843/16973
An optical isolator circuit has been designed to allow audio signals to pass while providing the isolation necessary to protect users from a wall outlet power source short circuit. The optical isolator used to pass the input signal in this design is a Fairchild 6N136 high speed opto-isolator.

Application Notes—Analog Optical Isolators Limiters If the magnitude of an AC signal varies over a wide range, it may be necessary to amplify or compress the signal before any audio processing can be performed. In other cases, the audio power has to be limited to prevent damage to an output device. Circuits that perform
optical isolation transformer for audio | diyAudio

I just read about the effect of bad input grounding on hum. And I read that an isolation transformer (copper + iron core) helps to reduce to the hum caused by bad connecting arrangement between two equipment. Would anyone tell if it is possible to use optical isolator (LED + light sensitive...

light—not electricity, thus the term optical isolator. These optical isolators are primarily digital in nature with fast response times suitable for interfacing with logic gates. Rise and fall times of a few microseconds, faster for some isolators, are typical. The analog optical isolator (AOI) also uses an optical link between input and output.
OPTO•USB Optical Isolation for USB DACs – AudioWise
https://audiowise-canada.myshopify.com/products/opto-usb
OPTO•USB™ is a USB optical isolator that provides RF isolated transmission of high-resolution digital audio from source to a USB DAC. OPTO•USB is better than any inline isolator, exotic USB cable or a lternative USB-over-optical solution* that uses an embedded copper wire in the optical fiber. OPTO•USB uses all-dielectric multimode optical fiber for total RF isolation: there is no ...
MT-071: Analog Isolation Amplifiers
https://www.analog.com/media/en/training-seminars/tutorials/MT-071.pdf
Capacitively-coupled isolation amplifiers have lower accuracy, perhaps 12-bits maximum, lower bandwidth, and lower voltage ratings—but they are low cost. Optical isolators are fast and cheap, and can be made with very high voltage ratings (4 -7 kV is one of the more common ratings), but
