AUDIO TEST and MEASUREMENT … FOR HOME, STUDIO, BROADCAST and LIVESOUND

Many things can happen in the complex world of audio and acoustics. Our highly developed test and measuring instruments and long years of experience help us to find and solve all sorts of audio related problems for our clients. We are offering the following T&M services and measurements:

 

· Sound pressure level (SPL) and energy-equivalent sound level (Leq) acc. to DIN 15905-5, SLV 2007, etc.

· Evaluation of acoustical quality of rooms and electro-acoustical systems, engineering reports

· Speech intelligibility (STI-PA), reverberation time (RT60), delay times, speaker polarity

· Linear and non-linear distortions (frequency- and phase-response, THD+N), signal-to-noise ratio

· Calibration and adjustment of PA and monitoring systems for mono, stereo and surround sound

· Calibration to X-curve (cinema-EQ according to DIN/IEC/ISO 2969 and Dolby, DTS and dci specifications)

· Analysis of analogue and digital audio interfaces (AES/EBU, AES3-id, ADAT Lightpipe, etc.), jitter analysis

· Analysis of  multichannel audio bitstreams (Dolby Digital, Dolby E, DTS) including metadata

· Loudness acc. to RLB, R2LB (ITU BS.1770/1771) und Leq(A) (IEC 60804), Dolby Dialogue Level, DialNorm

· Solutions and general problem solving for audio, video and broadcast systems
