The baudline time-frequency browser is a signal analysis tool designed for scientific visualization. It runs on several Unix-like 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.




Baudline binaries are available for free download.[4] The binaries may be used for any purpose, though no form of redistribution is permitted.[24] Source code is available for purchase under a number of licenses.[1] While the Baudline website states that the source code is dual-licensed, under both a proprietary license and a version of the GNU General Public License, no source code released under this dual-license is made available for download on the software's website nor has been shown to exist elsewhere.[25]
