1. Bluetooth audio codecs in a real-time interactive context
Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologiSammanfattning : 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
2. SIGNALBEHANDLING MED AVANCERAD BLUETOOTH-TEKNIK OCH OPTIMERADE OPERATIVSYSTEM : Optimera audiosystemet i ett avancerat inbyggt system med en fler-trådad programvara och synkroniserings mekanism
Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : This study is about replacing an old bluetooth module with a new variant, namely the BM83 which is an integrated circuit that contains an internal DSP circuit, profiles and important functions such as noise reduction, acoustic echo removal and EQ filtering. The purpose of this study is to replace the old module with the BM83, as well as explore the internal DSP circuit in the BM83. LÄS MER
3. Evaluation of the Perceived Speech Quality for G729D and Opus : With Different Network Scenarios and an Implemented VoIP Application
Master-uppsats, Linköpings universitet/InformationskodningSammanfattning : 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.
