Edges in waveforms indicate high frequencies
The frequency perception in humans is exponential (that’s why 10khz isn/t in the middle)
Half/double of a given frequency is an octave
Ex: 500 - 1000 - 2000hz
ADAT Connection (important) interface expander
5.1 (5 speakers, 1 subwoofer)
DSP (Digital signal processors) -
The built-in digital signal processor (DSP) calculates plug-ins directly in the audio interface and thus saves the long diversions via the computer. In this way, computationally intensive effects such as reverb can be used in real time and without burdening the CPU.
Allpass filter - used in phasers
Linear is better than no linear
Transitor - hard clipper
Tube - smooth behavior
Saturation also cause compression
