>>107903905You should not let Yotsuba listen to dubstep.
negative volume is kinda rad as a concept
>>107906298If you take amplification to broadly mean multiplying your signal by a scalar, then you can kind of stretch "negative amplification" into being an inversion of polarity of your signal. Balanced cables implement this all the time by having two copies of the signal being sent down the line, side by side, while one of them is inverted at the source. Since both are so close they basically accumulate the same noise, and you can invert one of the two at your output so that two inversions lead to the signal being in-phase and the noise accumulated instead gets inverted. When you then sum the pair, the noise cancels out
