Abstract

The intelligent accompaniment generating system includes an input module, an analysis module, a generation module and a musical equipment. The input module is configured to receive a musical pattern signal derived from a raw signal. The analysis module is configured to analyze the musical pattern signal to extract a set of audio features, wherein the input module is configured to transmit the musical pattern signal to the analysis module. The generation module is configured to obtain a playing assistance information having an accompaniment pattern from the analysis module, wherein the accompaniment pattern has at least two parts having different onsets therebetween, and each onsets of the at least two parts is generated by an algorithm according to the set of audio features. The musical equipment includes a digital amplifier configured to output an accompaniment signal according to the accompaniment pattern.

Dependent claims

A method for assisting a user to play an instrument in a system including an input module, an analysis module, a generating module, an output module and a musical equipment having a computing unit, a digital amplifier and a speaker, the method comprising steps of:

receiving an instrument signal by the input module;
analyzing an audio signal to extract a set of audio features by the analysis module, wherein the audio signal includes one of the instrument signal and a musical signal from a resource;
generating a playing assistance information according to the set of audio features by the generating module;
processing the instrument signal with a DSP algorithm to simulate amps and effects of bass or guitar on the instrument signal to form a processed instrument signal by the computing unit;
amplifying the processed instrument signal by the digital amplifier;
amplifying at least one of the processed instrument signal and the musical signal by the speaker;
and
outputting the playing assistance information by the output module to the user, wherein:
the playing assistance information includes an accompaniment pattern;
the set of audio features of the musical signal includes a set of chord information;
the resource includes at least one of a website, media service and local storage;
the system further includes a cloud system;
the musical signal is associated with a database having plural sets of pre-build chord information including the set of chord information of the musical signal;
and
the cloud system or the output module provides the user with the playing assistance information having a difficulty level according to the user's skill level.
