Abstract

The invention relates to a real-time audio signal editing method and circuit.The circuit consists of a power generating circuit and an overtone synthesis circuit, wherein an audio signal is input to the power generating circuit, the output end of the power generating circuit is connected with the input end of the overtone synthesis circuit, and the overtone synthesis circuit outputs a processed overtone signal.The real-time overtone editing circuit adopts an analog circuit to achieve a frequency multiplication function, utilizes the advantages of high speed of the analog circuit, can operate any audio input signal to obtain higher-harmonic signals.

Description

Technical field [0001] The invention belongs to the field of audio signal editing, in particular to a real-time overtone editing circuit. Background technique [0002] The frequency of the audio signal is (20~20000) Hz, and the span reaches 3 orders of magnitude. If overtones are considered, the upper frequency limit is at least 100kHz. Subtle changes in the frequency spectrum of the audio signal will cause different hearing sensations. Therefore, the processing of audio signals has long become an indispensable method in electronic audio production and performance aggregation. [0003] Overtone is the superposition of fundamental frequency and octave frequency signal. The fundamental frequency determines the pitch, and the octave determines the timbre, so the overtone has a timbre. Electronic music production or live performances often require specific timbre, and various effectors can achieve rich timbre. But the sound of the effector is fixed. For example, the commonly used...
