Nelson Acoustics Trident software is a real time multichannel, multiple analysis acoustic measurement application for use in acoustic and hearing sciences laboratory applications.
SigPro generates various noise sources or sine waves and plays WAV files at the desired sound pressure levels. Up to 8 independent sources can be generated real time of either pure tones, white, pink, red, full or 1/3 octave band-limited noise. WAV files of any sample rate can be looped to the desired length.
The Sound Quality Analyzer (SQA) from Nelson Acoustic Software conducts psychoacoustic sound quality analysis on standard audio WAV format files. SQA is a low cost, easy to learn to use, sound quality analysis tool for use with product and equipment noise emission recordings.
The WAV File Analyzer (WFA) from Nelson Acoustic Software is a post process analyzer for audio WAV Files that provides A-weighted and 1/3 octave band sound pressure levels versus user selectable time intervals. An integrated WAV file player allows users to listen to the file while examining the sound level vs time history. The Wave […]
