Introduction

Trinnov SRP offers high quality surround recordings from a compact microphone array placed in the middle of a sound scene. It has been specially designed to meet modern production challenges to deliver high quality surround sound experiences to the end listener with reasonable engineering effort.

Features

The Trinnov SRP package includes: The SRP digital signal processor dedicated to High Spatial Resolution multichannel recording. SRP receives the signals from a microphone array composed of 8 omnidirectional microphones and delivers the multichannel signals. The Omni-8 microphone mount with sets of adaptation rings to build the microphone array by accurate placement of 8 omnidirectional microphones. The HSR-5.0 software package including 8 filterbanks dedicated to High Spatial Resolution 5.0 recording. Additional software plug-ins for temporal and spatial monitoring.

Trinnov SRP is easy to operate:

• The microphone array is placed at the recording point like a stereo pair.
• The microphone signals are sent to the SRP using standard studio preamp and converters.
• The SRP delivers 5.0 sound respecting ITU standard.
