For audio, the signal has been inverted many times getting from microphone to recording to speaker. Most audio boxes try to invert an even number of times. (not inverted) Your eyer can not tell if audio is inverted.if it will cause any problems how invert the inverted output?
Your output filter (4.7uF/8Ω) will remove everything below 4kHz.What about this circuit
If you are bothered, then connect the speaker reversed with the - terminal to the signal and the + terminal to ground, then the signal will be the right way round again.
Similar to your circuit, it has low efficiency, high distortion, and a poor low frequency response (due to the low value output capacitor).What about this circuit
That is a misconception.Human voice ranges from 85Hz to 255Hz
Define "audio".What value of cut-off frequency is required for audio?
That is still a vague question.So what value of cutoff-frequency will generate a natural sound not too low or too high?
