conversion of single ended audio input to differential ...

The vintage way of getting differential audio signals from a single-ended input consisted of merely using an audio frequency transformer, usually a 2 pin input 3 pin output little thing, with a 1:1 turns ratio. The single-ended signal feeds the transformer input, and the output side is a differential signal pair you can bias to wherever you need it to be - connect the middle pin of …
Balanced and Differential - Hairball Audio
https://www.hairballaudio.com/blog/resources/diy-resources/balanced-and-differential
The differential input senses a signal by measuring the voltage difference between conductors. Signal voltages common to both conductors (the noise) are ignored. So in an impedance balanced line that has a 1V signal on one conductor and no signal on the other (0V), the input would pass a 1V signal ( the difference between the two conductors). This is an example of a …

With the differential input, a dual potentiometer is a must for a mono system and a quad must be used for the stereo system. The easiest implementation is to place the resistor in the potentiometer between the input audio signal and ground. The wiper will connect to the audio amp's input. The output from the wiper is a ratio of the input signal.

measured using a multi-channel differential input ADC. Differential inputs can offer a performance improvement over single-ended inputs by measuring the difference in voltage between the positive and negative terminals of the sensor. This provides common mode rejection. Choose pseudo-differential ADCs for DC common-mode voltage rejection. For sensors

https://electronics.stackexchange.com/questions/349890/is-audio-signal-passing-through-headphone-differential
Any time a voltage is applied thru a pair of wires to a load, it is differential but not necessarily balanced. However some signal pairs have differential drivers such as car audio power amplifiers and RS485. But don't confuse that with the fact that what is received is a differential voltage, even if the return reference is 0v or ground.
Single Ended versus Differential Inputs (Analog Input)
https://kb.mccdaq.com/KnowledgebaseArticle50277.aspx?Keywords=Analog-Input&Keywords=Analog-Input
Most data acquisition systems provide both a single ended and a differential input connection. The one difference between the two types of configuration is the common connection (low level ground). a) A single ended input measures the voltage between the input channel high and low level ground common to all the inputs. This type of configuration allows for the DAQ …

Many headphone amps, or chip speaker amps have differential input, which makes life easier as you just require ~1uF ceramic caps. It is also preferable to keep the signal fully differential if you can as the common mode noise on these bluetooth SOC's is pretty horrendous - which is partly why they have differential outputs, the other reason being they have built-in …
