The baudline time-frequency browser is a signal analysis tool designed for scientific visualization. It runs on several Unix operating systems under the X Window System. Baudline is useful for real-time spectral monitoring, collected signals analysis, generating test signals, making distortion measurements, and playing back audio files.
