Baudline is a time-frequency browser designed for scientific visualization of the spectral domain. Signal analysis is performed by Fourier, correlation, and raster transforms that create colorful spectrograms with vibrant detail. Conduct test and measurement experiments with the built in function generator, or play back audio files with a multitude of effects and filters. The baudline signal analyzer combines fast digital signal processing, versatile high speed displays, and continuous capture tools for hunting down and studying elusive signal characteristics.
The FAAC project includes the AAC encoder FAAC and decoder FAAD2. It supports several MPEG-4 object types (LC, Main, LTP, HE AAC, PS) and file formats (ADTS AAC, raw AAC, MP4), multichannel and gapless en/decoding as well as MP4 metadata tags. The codecs are compatible with standard-compliant audio applications using one or more of these profiles.
WorldStation is a Java-based control panel to control the Ten-Tec DSP RX-320 shortwave receiver. The RX-320 is a "black box" radio which has no front-panel and is controlled via your PC's serial port. With an appropriate antenna, the RX-320 will allow you to listen to thousands of broadcasts from around the world. WorldStation features integrated Xbase frequency database support and advanced scanning to allow the user to visualize the radio spectrum.
ebook2cw is a command line program that converts a plain text file (like an eBook) to Morse code (CW) MP3 or OGG files. Morse parameters like speed and tone frequency, and audio parameters such as bit rate, sample rate, and quality can be changed by command line switches. It automatically splits and numbers the output files by chapters.
