Spectralissime

Spectralissime is a 60, 120 or 240 bands spectrum analyzer application for Windows. Based on optimized band pass filter bank, it performs a high end frequency analysis with the same precision on the full range (20Hz 20 KHz), 10 to 100 times per second. Based on original VB-Audio frequency analyzer engine developed in 2001 as Plug-in, Spectralissime takes advantage of 15 years of experience in audio digital measure, to become simpler but with new essential functions.

Spectralissime can use any audio device as audio source (WDM; KS, MME, ASIO) and can manage up to 64 I/O on ASIO device (patch function allows selecting channel). Two Channels can be selected and called A & B. This first Spectralissime version performs a single channel view, but the analysis can then done on A, B, A+B or A-B. Spectralissime can also get signal from a VBAN Stream and then can be deported to a second computer connected on local network (Ethernet). Monitoring option allows selecting another audio device to monitor the analyzed signal.

Spectralissime proposes new ways of viewing spectrum for a better analysis and comprehension of audio signal. It proposes different scale in gain (6dBfs, 10dBfs, dB SPL) and frequency representation (decade or octave) and can be used as a measuring tool with a calibrated microphone. The Isophonic Scale shows isophonic curve and displays scale in dB SPL. A calibration value can be set to adjust level to any microphone for any acoustic measure.
