 r with cosparsity\, by S. Kiti\, et al. 2014 IEEE International Conference
  on Acoustics\, Speech and Signal Processing (ICASSP).Abstract\nIn this re
 search proposal an introduction to compressed\nsensing applied to problems
  in acoustics is given. Due\nto different types of sparsity that live in t
 he acoustic domain\,\nsparse methods are a crucial tool for handling acous
 tical high dimensional\ndata. The focus is on the sparse inverse problems\
 nrelated to the reconstruction of sound pressure field in a room\nfrom a s
 mall number of microphones randomly distributed.\nA combination of knowled
 ge in signal processing\, acoustics\,\noptimization and algorithms is esta
 blished as the framework for\nproblem solving in this domain. Overview of 
 the current results\nis given\, as well as the ideas for further research 
 directions.
