The only solution for directional underwater recordings.
The Sonar surround Directivity-Sphere gives omnidirectional hydrophones a directivity close to a supercardioid. Usable up to a depth of 1000m. Maritime life fills the underwater world with countless interesting sounds. Due to the particular acoustic characteristics of that medium, it has been impossible to make high quality multi channel recordings under water, until now.
After two years of research, Sonar Surround has succeeded in developing a new awarded and patented technique to give omnidirectional hydrophones a polar pattern close to a supercardioid. Thus audio engineers now have the possibility to utilize approved recording techniques even underwater.
Harmonic sound despite directivity. Being close to the human head shape spherical microphones are known for their natural, "humanly" sound perception especially pronounced with multichannel arrays. By directing the hydrophone in a mainly additive way most interferences can be avoided.
