The audio signal coming from your music player needs a bit of massaging before it can be read by the analog inputs on the NeoTrellis M4. We'll build a small circuit using two capacitors and two resistors to remove the DC bias and center the incoming audio around the correct voltage for the NeoTrellis M4's analog-to-digital converter (ADC).

https://electronics.stackexchange.com/questions/486219/line-input-circuit
I'm trying to design an unbalanced line input for an audio device using a single supply. I would like the input stage to provide variable gain between 0 and 2. This is what I have come up with so far: I have been running some basic simulations in LTspice that suggest the circuit is working as intended, so I hope I'm not too far off the mark.

The circuit in Figure 5a acts like a unity gain buffer, with a voltage divider on the input voltage. The gain will be at its minimum value of –17 dB (1/7). For RS = 470 Ω, R1 can be calculated: The circuit in Figure 5b acts like a non-inverting gain stage, with the input resistance R1 being ignored. The gain will be at its maximum value of 17 dB (7).
