Embedded Acoustics is the manufacturer of Pebbles: a covert distributed audio recording system which uses multiple recorders (up to 30 pcs) for blanket coverage of large areas. Pebbles recorders can be deployed ad hoc and with minimal preparation time (minutes). Pebbles offers a convenient and cost-effective solution whenever larger numbers of microphones are needed. Software is provided to recombine audio from multiple recorders into a single output file (e.g. "walk and talk" scenarios).
