    I don't suggest to use headphone and analyzer in parallel for various reasons. You will have to keep at high volume for getting full display (vertical) on the analyzer. Impedance mismatch of the headphone and the analyzer may cause the problems you explained. Some music player's output may be coming out of bridged amplifier where grounding one line can cause problem. Thats said, you can experiment and make It working. And make sure grounding is perfect.

    1. 0b00000001 is correct

    2. Next SAMPLES size you can use after 64 is 128 which consumes lots of memory and Arduino-FFT becomes really slow with that number.

    Char consumes only 8 bits compared to 16 bits by int . Here we don't need large numbers hence char is good enough which saves memory.
