1. 1. Exploiting the Overtones in Online Localization of Sound Sources

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :David Sundström; [2022]
   Nyckelord :Multi-pitch estimation; localization; block sparsity; sparse recursive least squares; online estimation; ADMM; adaptive dictionary; Mathematics and Statistics;

   Sammanfattning : 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

3. 2. A Parametric Method for Multi-Pitch Estimation

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Filip Elvander; [2015]
   Nyckelord :Mathematics and Statistics;

   Sammanfattning : This thesis proposes a novel method for multi-pitch estimation. The method operates by posing pitch estimation as a sparse recovery problem which is solved using convex optimization techniques. In that respect, it is an extension of an earlier presented estimation method based on the group-LASSO. LÄS MER

4. 3. Multi-Pitch Estimation of Inharmonic Signals

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Tommy Nilsson; [2013]
   Nyckelord :Mathematics and Statistics;

   Sammanfattning : A signal with harmonic structure is often characterized by its fundamental frequency, or pitch. This single parameter contain vital information of a range of applications such as musical transcription, tuning of stringed instruments, speech processing and more. LÄS MER
