Efficient Subjective Evaluation Testing

■ Create audio material libraries

■ Simultaneously read WAV files and support audio data in ATOM format

■ Build evaluation projects with multiple evaluation tasks

■ Create test users to launch tests for single or multiple evaluators

■ Clear, structured evaluation interface for users

■ Rapid configuration of complex test procedures

■ Customizable scoring criteria

■ Export evaluation results to Excel

Listening Evaluation Methods

■ A-B Comparison Method

■ Ranking Method

■ Categorical Judgment Method

■ Semantic Differential Method

■ Customizable Evaluation Methods

Multiple Evaluation Modes

■ Single-client evaluation mode: sequential evaluation for multiple users; multiple tasks can be created for evaluators to assess in turn

■ Listening room evaluation module: supports time-shared evaluation by multiple participants

Statistical Analysis of Test Results

■ Conduct consistency and correlation analysis on subjective test data

■ Support Pearson and Spearman correlation analysis

■ Identify outliers via box plots

Subjective-Objective Correlation Analysis

Subjective evaluation results can be imported into ATOM Analyzer. Correlation analysis between subjective ratings and objective psychoacoustic calculation results helps establish a sound quality evaluation model.
