Name: Pitch Shifter with Single-Sideband AM
ID: m15467
Language: English (en)
Summary: Pitch shifting makes an interesting special effect, especially when applied to a speech signal. Single-sideband amplitude modulation (SSB-AM) is presented as a method to shift the spectrum of a source signal in the same way as basic AM, but with cancellation of one sideband to eliminate the “dual voice” sound of conventional AM. Pre-filtering of the source signal to avoid aliasing is also discussed.
Subject: Science and Technology
