Audio Device Dynamic Display for Seamless Music Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing acoustic device and software for Digital Audio Workstation (DAW) and Desk Top Music (DTM) applications are insufficient in allowing users to easily set reservations for mixing music pieces while a music piece is being played.
Innovation Solution
An acoustic device with a display controller and reservation unit that allows users to set playback start points and mixing points for multiple music pieces during playback, enabling seamless switching between playback and reservation-setting screens, with the display controller showing waveform information to facilitate intuitive mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display shows a moving waveform indicating playback status, then the user can visually track playback progress, but the user cannot easily access reservation-setting functions without interrupting playback
Solution Approach 1:
The display dynamically switches between two modes: a first display mode showing the moving waveform during playback, and a second display mode showing the reservation-setting screen. This dynamic reconfiguration allows the system to adapt to different user needs without interrupting playback, resolving the contradiction between ease of operation and time loss.
Solution Approach 2:
The display functionality is segmented into distinct modes that can be activated independently. The waveform display and reservation-setting interface are separated into switchable segments, allowing users to access reservation settings without stopping the playback waveform, thus maintaining both continuous playback and easy access to settings.
2Adaptability or versatility
If the display switches between playback screen and reservation-setting screen, then the user can access reservation functions, but the visual continuity of playback status is disrupted
Solution Approach 1:
The playback action continues uninterrupted in the background while the display mode switches. The waveform keeps moving and playback proceeds normally, maintaining the continuity of the useful action (music playback) even as the display adapts to show different information based on user needs.
Solution Approach 2:
The display controller acts as an intermediary between the playback system and the user interface. It manages the switching between display modes without affecting the underlying playback process, allowing versatile screen functionality while preserving visual information about playback status through the moving waveform indicator.
3Measurement precision
If the waveform is fixed on the display, then the reservation-setting interface is stable, but the user cannot track current playback position
Solution Approach 1:
The waveform display transitions from a static reference position to a dynamic moving indicator. The waveform moves in sync with playback progress, providing precise visual feedback about current playback position without requiring complex additional indicators or controls.

AI summary
An acoustic device configured to mix two or more music pieces is provided. The acoustic device includes a display controller configured to switchably display information related to audio mixing on a display device; and a reservation unit configured to set the music pieces to be mixed and a playback start point in each of the music pieces. The display controller is configured to switchably display on the display device a first screen, on which a first image indicating a playback status of a first music piece being played is moved based on a second image indicating a current playback point of the first music piece, and a second screen, on which the first image is fixedly displayed and the second image is moved based on the first image in accordance with the current playback point. The second screen includes a reservation-setting screen related to the reservation unit.
