Terminal Device for Real-Time Audio Track Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing musical performance systems lack a simple and efficient method for users to switch playback parts while playing electronic musical instruments, as current systems require complex operations to manage audio source separation and mixing.
Innovation Solution
A musical performance system comprising an electronic musical instrument and a terminal device, where the terminal device processes and outputs track data or pattern data based on user instructions from the instrument, allowing seamless switching of playback parts through a user-friendly interface, such as a foot pedal or keyboard operation, to generate and mix audio signals in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio source separation technology is used to separate audio data into multiple parts, then users can select and play specific parts (e.g., piano, vocal, guitar), but the operation complexity increases when switching between different playback parts
Solution Approach 1:
The system dynamically switches between different playback parts (piano, vocal, guitar, etc.) based on user input during performance, allowing the audio mixture to change in real-time without requiring complex reconfiguration. The terminal device receives simple switch commands from the electronic musical instrument and automatically adjusts which separated audio tracks are played back.
Solution Approach 2:
The terminal device automatically manages the complex task of selecting and mixing multiple separated audio tracks based on simple switch commands from the electronic musical instrument. The system self-adjusts the audio output without requiring the user to manually configure each track, thereby simplifying operation while maintaining versatility.
2Adaptability or versatility
If multiple audio tracks are mixed and played back through a terminal device, then audio quality and flexibility improve, but the system complexity and number of required components increase
Solution Approach 1:
The terminal device performs multiple functions: it separates audio sources, stores multiple audio tracks, mixes them according to simple switch commands, and plays back the resulting mixture. This multi-functional approach consolidates what would otherwise require separate devices into a single terminal device, reducing overall system complexity while maintaining audio playback flexibility.
Solution Approach 2:
The electronic musical instrument serves as an intermediary that sends simple switch commands to the terminal device, which then handles the complex audio processing. This intermediary role allows the system to maintain simplicity at the user interface level while achieving sophisticated audio mixing and playback capabilities through the terminal device.
