Baudline is a real-time signal analysis tool and an offline time-frequency browser. Baudline project has a built-in tone generation capability and it can play back audio files with a multitude of effects and filters.

Designed for environmental analysis missions that range from modulation parameter measurements to searching for transient signals that go bump in the night, baudline combines fast digital signal processing, versatile high-speed displays, and continuous capture tools for hunting down and studying elusive signal characteristics.

Here are some key features of "Baudline":
192 kHz real-time bandwidth
96 dB dynamic range
Real or Quadrature input
Multiple sound card support
Input Digital Down Converter (tuner)
Configurable input channels that can perform various operations
Channel Equalization
Frequency, time, amplitude, and sample probability distribution analysis
Drift Integration "de-chirping"
High speed displays
Test signal generation
