Abstract
The disclosed technology relates to a process for detecting musical artifacts within a musical composition. The detection of musical artifacts is based on analyzing the energy and frequency of the digital signal of the musical composition. The identification of musical artifacts within a musical composition would be used in connection with audio-video editing.
Claims17
A computer-implemented method, comprising:
- receiving a primary waveform representing a musical composition, wherein the musical composition comprises a plurality of musical artifacts;
- filtering the primary waveform to generate alternative waveforms associated with the plurality of musical artifacts, wherein filtering the primary waveform is performed using two or more interlaced band pass filters that output two or more secondary waveforms, wherein the filtering the primary waveform further comprises:
- calculating a samples' module of the two or more secondary waveforms;
- and
- determining if the samples' module exceeds a first predetermined frequency range threshold;
- and
- automatically analyzing the alternative waveforms to identify time points in the primary waveform that correspond with the plurality of musical artifacts.
A non-transitory computer-readable medium comprising instructions that identifies musical artifacts, the instructions, when executed by a computing system, cause the computing system to:
- receiving a primary waveform representing a musical composition, wherein the musical composition comprises a plurality of musical artifacts;
- filtering the primary waveform to generate alternative waveforms associated with the plurality of musical artifacts, wherein filtering the primary waveform is performed using two or more interlaced band pass filters that output two or more secondary waveforms, wherein the filtering the primary waveform further comprises:
- calculating a samples' module of the two or more secondary waveforms;
- and
- determining if the samples' module exceeds a first predetermined frequency range threshold;
- and
- automatically analyzing the alternative waveforms to identify time points in the primary waveform that correspond with the plurality of musical artifacts.
A system for identifying musical artifacts, the system comprising:
- a processor;
- and
- a non-transitory computer-readable medium storing instructions that are configured to cause the system to execute operations comprising:
- receiving a primary waveform representing a musical composition, wherein the musical composition comprises a plurality of musical artifacts;
- filtering the primary waveform to generate alternative waveforms associated with the plurality of musical artifacts, wherein filtering the primary waveform is performed using two or more interlaced band pass filters that output two or more secondary waveforms, wherein the filtering the primary waveform further comprises:
- calculating a samples' module of the two or more secondary waveforms;
- and
- determining if the samples' module exceeds a first predetermined frequency range threshold;
- and
- automatically analyzing the alternative waveforms to identify time points in the primary waveform that correspond with the plurality of musical artifacts.
