Unit testing of ETSI DECT codec

Abstract

The low complexity communication codec (LC3Plus) plus performs audio quality tests which are both subjective and objective ranging from narrowband to fullband are tested at clean and distorted channels. The relevant DECT scenarios for transcoding and VOIP are investigated. In this paper we take LC3Plus from ETSI and test the correctness by compiling the program under linux environment. A careful planning of the test stimuli helps create useful test cases for `testing the LC3Plus encoder and decoder. Testing is performed meticulously to verify the correctness of the standard.
