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.
Applications
- Acoustic cryptanalysis[4][5][6][7][8]
- Audio codec lossy compression analysis [9][10]
- Audio signal processing
- Bioacoustics research
- Data acquisition (DAQ)
- Gravitational Wave analysis[11][12]
- Infrasound monitoring
- Musical acoustics[13][14][15]
- radar[16][17][18]
- Seismic data processing
- SETI[19][20][21]
- Signal analysis
- Software Defined Radio[22][23]
- Spectral analysis
- Very low frequency (VLF) reception[24]
- WWV frequency measurement[25][26]
Features
- Spectrogram, Spectrum, Waveform, and Histogram displays
- Fourier, Correlation, and Raster transforms
- SNR, THD, SINAD, ENOB, SFDR distortion measurements
- Channel equalization
- Function generator
- Digital down converter
- Audio playing with real-time DSP effects like speed control, pitch scaling, frequency shifting, matrix surround panning, filtering, and digital gain boost
