Multitrack Recorder Input Source Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multitrack recorders face operability issues due to the need for users to manually switch input sources based on track type, leading to potential setting errors when tracks are set to either monaural or stereo types, complicating the user experience.
Innovation Solution
A multitrack recorder with setting means to assign input sources automatically based on track types, using built-in microphones and input ports, ensuring correct allocation regardless of track type, thereby enhancing user convenience and preventing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the number of tracks is limited to a constant value and some tracks can be set to monaural or stereo type, then the multitrack recorder can be made compact for portability, but the user must manually switch input sources according to track type which complicates operation and increases setting errors
Solution Approach 1:
The control unit automatically determines which input sources to present based on the track type (monaural or stereo) without requiring manual user selection. The system serves itself by autonomously configuring input sources according to the selected track mode, eliminating the burden of manual switching and reducing setting errors.
Solution Approach 2:
The system pre-configures the appropriate input sources before the user needs to record. When a track is set to monaural or stereo type, the control unit automatically selects and presents the correct input sources in advance, so the user doesn't need to manually switch or configure input sources during the recording process.
2Adaptability or versatility
If the user manually switches input sources according to track type, then the multitrack recorder can operate with limited tracks, but the user must correctly grasp which track is monaural or stereo type which increases cognitive load and setting errors
Solution Approach 1:
The display unit provides visual feedback showing which input sources are available for each track based on its type. The control unit processes user selections and automatically updates the input source configuration, providing continuous feedback that simplifies the user's cognitive task by automatically managing the complexity of track-type-specific input source selection.
3Reliability
If dedicated screen switching is required to ascertain track types, then setting accuracy can be improved, but the operation becomes troublesome and operability deteriorates
Solution Approach 1:
The display unit serves multiple functions: it shows track information, indicates available input sources, and guides the user through the recording process. By integrating these functions into a single display interface, the system eliminates the need to switch between dedicated screens for different purposes, maintaining reliability while improving ease of operation.

AI summary
A multitrack recorder can allocate an input source in a simple manner without regard to whether a track is a monaural type or a stereo type. The multitrack recorder can set tracks 3 and 4, among a plurality of tracks 1 through 4, to either a monaural type or a stereotype. Track types are stored in memory. On occasion of allocation of an input source to each of the tracks, available input source alternatives are displayed in a display section while being changed according to whether the track is a monaural type or a stereo type.
