HpW is proud to announce the new version 3.4 of the unique
FFT-based analysis software HpW Works. The new release includes an
improved lookout and several new display options, like Real Time display,
THD, THD+N, Dynamic range (DR), SNR and level calculations, phase view,
min/max band view, which can be displayed on each spectrum. The analysis
data showing more detailed information is presented on a separate
data window. Using dual channels, the phase relationship is also shown.
Analyzing signals, in the labor, development or music studio is the
target use of HpW Works. HpW delivers high-end measurement for an
astonishing low price. The full system includes a FFT-software plus
signal generator, operating with any PC sound card or digital I/O hardware.
For the input and output section various plugin modules are available
and custom plugin build.
