A/B comparison listening test script

This script M file automates and manages a double-blind AB comparison test.

Description

This script M file automates and manages a double-blind AB comparison test for subjective comparison of audio file quality. Applications include perceived differences in audio or speech tracks after encoding. The program handles track selection, order, scoring, and storage. Requires WAV files for testing, quality headphones, and listeners to perform tests. Since it is a double-blind test, few listeners are needed to create valid results.
