Cycle Map Audio Synthesizer for Complex Sound Reproduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wavetable synthesizers are inadequate for recreating complex acoustic sounds like singing or talking, as they do not accurately store and reproduce the evolving pitch and volume of each cycle in the original sound.
Innovation Solution
The UltraWave method uses a Cycle Map to store and manipulate audio, frequency, and volume data for each cycle, allowing for precise recreation of sounds by altering pitch and volume over time, and incorporates an Arc Map to efficiently represent and manipulate audio data, enabling more accurate playback of complex sounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional wavetable synthesizers are used to store cycles in a wavetable, then the synthesizer can reproduce sounds, but it cannot accurately store and reproduce the evolving pitch and volume of each cycle in complex acoustic sounds
Solution Approach 1:
The patent divides the audio signal into individual cycles and stores each cycle's characteristics (pitch, volume, waveform) separately in a Cycle Map data structure. This segmentation allows precise storage of evolving pitch and volume for each cycle, enabling accurate recreation of complex acoustic sounds like singing or talking, which conventional wavetables cannot achieve.
2Manufacturing precision
If the Cycle Map stores variable length and variable height data for each cycle, then the sound quality and accuracy improve, but the data structure and processing complexity increase
Solution Approach 1:
The patent implements nested data structures where the Cycle Map contains arrays of Cycle objects, each representing a specific cycle with its own waveform data, pitch information, and volume envelope. This nested organization allows the system to handle variable length and height data efficiently while maintaining a structured approach to processing, balancing precision with manageable complexity.
Solution Approach 2:
The Cycle Map dynamically stores and processes variable-length cycle data with varying pitch and volume characteristics. The system adapts the data structure to the specific requirements of each audio segment, allowing flexible manipulation of pitch and volume envelopes without requiring a fixed, rigid data format, thus managing complexity through dynamic adaptation.

AI summary
A sound synthesizer including an audio import system, a database, and a processor. The processor is configured to compile audio data into a cycle map to represent pitch as a series of variable lengths, and volume as a series of variable heights. The processor is further configured to compile the audio data into an arc map to represent audio data as a series of variable lengths, and volume as a series of variable heights.
