Spring reverberation model

Abstract

The invention relates to the field of digital audio processing, in particular to a spring reverberation model, comprising an audio input module, used for receiving original audio signal input; a reverberation generating module, used for reverbing original audio signals; a special sound effects generating module, used for impacting circulating vibrato unique to spring reverberation to the original audio signals; an audio output module, superposing output signals of the reverberation generating module, output signals of the special sound effects generating module and the original audio signals and outputting them via the audio output module. The spring reverberation model is simple in structure, easy to implement and high in echo density without acoustic coloration, provides well natural sound and can serve as an excellent reverberation model in practice.

Description

technical field [0001] The invention relates to the field of digital audio processing, in particular to a spring reverberation model. Background technique [0002] Reverb sound effects play an integral role in the production and playback of radio, television, and musical productions. It plays a very important role in beautifying the timbre of music, singing and voice, recreating art and producing special sound effects. [0003] For the research on reverberation sound effects, there are no published models except several classic models. At the beginning of 2010, Lexicon, the world's largest manufacturer of reverb effect hardware, released the high-end reverb effect LexiconPCMReverb, which integrates all the excellent reverb algorithms of the company over the past 35 years, including hall, room, reverb There are many different reverb effects such as reverberation room, concert hall, plate type, classic plate type, and various algorithm effects have their own characteristics....

AI Technical Summary

Problems solved by technology

The current spring reverb has the following problems: 1. Due to the high requirements of the spring material and manufacturing process and 2 impedance converters, the price of the spring reverb is relatively expensive; 2. The volume is large and it is not easy to install; 3. Usually the spring The reverberator is relatively close to the speaker and transformer, because they are all inductive devices, which are prone to mutual interference, bringing hum and noise, and because the signal is extremely small, the post-stage amplification gain is very high, and it is easy to howling and self-excitation
