Frequency Shifter raises or lowers the frequency of an input signal using a complex amplitude modulation-like technique. Unlike the pitch shifter, it does not preserve the harmonic relationships between the various tones and harmonics in the input signal. In the next...

Amplitude panning originates from stereophony, initially developed by Blumlein in the early 1930s. In essence, this system transforms the phase and amplitude difference of a signal recorded by stereophonic reception systems (mic stereo pairs, or the ears for that...

The A/B stereo recording technique is also known as “Spaced Pair”. It involves two microphones positioned anywhere from 3 to 10 feet apart, meant to capture the same sound source. The distance between them will create time-of-arrival (phase) and level...
