Method and relative device for producing echo effect

Abstract

This invention provides a method for generating echo sound effect and related devices to generate an output signal with an echo effect according to the input signal. This invention first of all sets a fixed value echo interval and delays the said input signal to sequently generate multiple delay signals and makes each delay time of a delay signal to the second signal equal to the said echo interval and numbers of the signals are determined according to the numbers of the echo intervals in the echo time step in the early stage of the echo effect. The delayed signals can be early stage echo part of output signals after the low-pass filter, and can form the later echo part in the output signals.

Description

technical field

[0001] The present invention relates to a method for designing and realizing reverberation sound effects and related devices / circuits, in particular to a reverberation sound effect generation method and method for adaptively generating a delay signal based on the number of echo intervals in the early reverberation to realize the early reverberation part Associated devices / circuits. Background technique

[0002] Touching music can soothe people's hearts and has become an important part of human life. According to research, pleasing music is not only related to the vocal characteristics of the instrument, the personal skills of the performer and singer, but also the environment in which the music is played. For the audience, the music performed in the professionally designed concert hall will be more vigorous and beautiful, with lingering reverberation. The special sound effect presented by music resonating and reverberating in the concert hall can be called ...
