  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. SIGNALBEHANDLING MED AVANCERAD BLUETOOTH-TEKNIK OCH OPTIMERADE OPERATIVSYSTEM : Optimera audiosystemet i ett avancerat inbyggt system med en fler-trådad programvara och synkroniserings mekanism
