3PASS flex: New Background Noise Simulation System for Multi-Microphone Arrangements

3PASS flex is HEAD acoustics new simulation system for measuring speech quality performance in the presence of background noise. It is particularly suited for testing multi-microphone systems, microphone arrays or beamforming microphones in real world conditions where multi-point noise simulation with flexible microphone and loudspeaker arrays is required. 3PASS flex reproduces any previously recorded sound field at distinct microphone positions, representative of typical use cases.

During Musikmesse 2017, Audionamix, officially released the world's first speech-specific, stand alone separation software, TRAX Pro 3 SP. TRAX Pro 3 SP allows audio engineers to isolate speech from background elements in mono or stereo recordings, separate speech from any kind of noise, improve speech intelligibility in archival recordings, clean up dialogue in film post-production without the need for ADR, and much more.

NTi Audio, headquartered in Schaan, Liechtenstein, NTi Audio attended this year’s meeting of the Swiss Acoustical Society (SGA), held under the theme “Practical Sound Measurements”. NTi presented its XL2 Audio and Acoustic Analyzer and provided practical demos of environmental noise, speech intelligibility, RT60 and sound insulation measurements.
