Thanks for remembering but today is baudline's 12th birthday. Version 0.78
was first released on September 27 2000.
I'm busy working on the next version of baudline. It will be faster, have improved spectrogram image quality, support larger FFT sizes, and fully utilize 64-bit memory addressing for larger buffers and loading bigger data files. There are also two new display windows for visualizing data in unique ways. Some other new features might make it too.
