Description |
Baudline is a time-frequency browser designed for scientific visualization
of the spectral domain. Signal analysis is performed by Fourier,
correlation, and raster transforms that create colorful spectrograms with
vibrant detail. Conduct test and measurement experiments with the built
in function generator, or play back audio files with a multitude of effects and
filters. The baudline signal analyzer combines fast digital signal
processing, versatile high speed displays, and continuous capture tools for
hunting down and studying elusive signal characteristics.
Explore, Analyze, and Discover.
