Trucs d'Acoustique
Personal Programs For Acoustic Applications
Project management tool for building acoustics. Vectorial floor plan drawing, multi-level management, regulatory compliance calculation, sound mapping and CATT-Acoustic export.
Impulse response, decay and FFT analyser for room acoustics and audio measurements. Integrated signal generator, sound level meter and STI calculation.
Sound absorption coefficient database for acoustic materials - research, comparison and reverberation time estimation.
3D waterfall spectrum analyser - displays the time evolution of a signal's frequency content as a cascaded FFT surface.
Core Acoustics
Impulse response, decay and FFT analyser for room acoustics and audio measurements. Integrated signal generator (noise, sine sweep), sound level meter and STI calculation.
- Impulse response analysis - EDT, T15, T20, T30, C50, C80, D50, TS
- FFT and frequency domain analysis
- Signal generator: white / pink / red noise, sine sweep (lin. / log.), tones
- Sound level meter with hardware device input
- Speech Transmission Index (STI) - IEC 60268-16 (2020)
- Schroeder integral, energy decay curves, RT cursor and magnitude range
Sound Absorption coefficient database
Sound absorption coefficient database for acoustic materials - research, comparison and reverberation time estimation.
- Search, selection and comparison of absorption properties of acoustic materials
- Simple estimation of absorption coefficient of porous materials
- Reverberation time estimation - Sabine, Eyring, Millington
Waterfall
3D waterfall spectrum analyser - displays the time evolution of a signal's frequency content as a cascaded FFT surface. Suited for room acoustics decay visualisation and loudspeaker analysis.
- Temporal decay (envelope) per frequency
- Selection of the analysis time and temporal resolution
- Frequency resolution selection (1/3 to 1/48 octave)
- 3D waterfall display (frequency × time × level)
- Configurable FFT window size, overlap and weighting
- Adjustable time and frequency resolution
