  1. 1. Bluetooth audio codecs in a real-time interactive context

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Gustav Johansson; Mattias Adevåg; Jacob Milton; [2023]
    Nyckelord :Bluetooth Low Energy; BLE; audio codec; LC3; aptX; real-time; interactive context; latency; perceived audio quality;

    Sammanfattning : The emergence of Bluetooth Low Energy in combination with optimized coders has made it possible to transfer digital audio at very low bitrates, paving the way for small devices with longlasting batteries. The aim of this study is to compare the audio codecs LC3 and aptX, as well as peoples’ attitude towards audio quality in different contexts. LÄS MER

  3. 2. Evaluation of the Perceived Speech Quality for G729D and Opus : With Different Network Scenarios and an Implemented VoIP Application

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Louise Almér; [2022]
    Nyckelord :Compression; Codec; audio; speech quality; quality of experience;

    Sammanfattning : Communication has always been a vital part of our society, and day-to-day communication is increasingly becoming more digital. VoIP (voice over IP) is used for real-time communication, and to be able to send the information over the internet must the speech be compressed to lower the number of bits needed for transmission.
