1. Approach for frequency response-calibration for microphone arrays
M1-uppsats, KTH/Hälsoinformatik och logistikSammanfattning : Matched frequency responses are a fundamental starting point for a variety ofimplementations for microphone arrays. In this report, two methods for frequencyresponse-calibration of a pre-assembled microphone array are presented andevaluated. LÄS MER
2. Stereo techniques and time delay compensation in classical music recording, the impact on the preferred spot microphone level in a mix
Kandidat-uppsats, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälleSammanfattning : This study investigates whether different stereo techniques used as a main array influences the preferred level from spot microphones when combined in a mix. Time delay compensation and its influence on spot microphone level was also examined. A clarinet soloist and a violin & piano duo were recorded as stimuli. LÄS MER
3. Gunshot Detection and Direction of Arrival Estimation Using Machine Learning and Received Signal Power
Master-uppsats, Linköpings universitet/Institutionen för systemteknikSammanfattning : Poaching is a persistent issue that threatens many of earth’s species including therhino. The methods used by poachers are varied, but many use guns to carry outtheir illegal activities. Gunfire is extremely loud and can be heard for kilometres. LÄS MER
4. Exploiting the Overtones in Online Localization of Sound Sources
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Localization of multiple sound sources from a microphone array is a challenging task that has been a research topic for decades. The challenges stem from the diversity of acoustic contexts due to reverberation and disturbances. LÄS MER
5. Automatic Virtual Tracking in a Multi-Participant Scenario for a Mobile Device
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : The aim of this thesis is to identify a speaker in a video stream by only using the camera of a smartphone. This creates the opportunity for a mobile application to track the speaking participant during a conference call. Conference systems that include this feature use a microphone array to localize sound and who the speaker is. LÄS MER
