Pyramic array: An FPGA based platform for many-channel audio acquisition
Array processing of audio data has many interesting applications: acoustic beamforming, source separation, indoor localization, room geometry estimation, etc. Recent advances in MEMS has produced tiny microphones, analog or even with digital converter integrated. This opens the door to create arrays...

| Resumo: | Array processing of audio data has many interesting applications: acoustic beamforming, source separation, indoor localization, room geometry estimation, etc. Recent advances in MEMS has produced tiny microphones, analog or even with digital converter integrated. This opens the door to create arrays with a massive number of microphones. We dub such an array many-channel by analogy to many-core processors. |
