Problems solved by technology

It can be seen that when the reverberation circuit has more orders, such as the fourth order, fifth order, or even more, the reverberation circuit needs to process the input signal multiple times, multiple delays are superimposed, and the circuit implementation is also very complicated. As a result, the circuit area is larger, the product volume is larger and the cost is higher

Abstract

The invention discloses a reverberation circuit, a control method of the reverberation circuit, a chip adopting the reverberation circuit and a device adopting the chip. The reverberation circuit is asimpler reverberation circuit, and the high-quality reverberation effect of adjustable reverberation orders and reverberation depth can be realized.

Description

technical field [0001] The invention relates to the field of sound synthesis, in particular to a reverberation circuit and its control method, a chip using the circuit and a device using the chip, in particular to a reverberation generating circuit in a sound synthesis device. Background technique [0002] The main technical solution for generating reverberation sound effects is to adopt the principle of delay superposition. Through various technical means, the sound source is processed first, and then the processed signal is delayed and superimposed, so that the reverberation effect can be realized. Existing reverbs include spring reverberators, DSP digital reverberation chips, and the like. The spring reverberator is a mechanical reverberator, which is bulky and cannot be miniaturized; while the DSP reverberation chip is expensive and complicated to use. For the existing reverberation circuit, if multi-order reverberation needs to be realized, the input signal needs to b...
