CWBot is an IRC bot to provide online services in Morse usable with the CWirc client. It can broadcast world news in Morse and Hellschreiber, RAC ham news, act as a MorseMail to CWirc repeater, be a CW tutor, or send fortune cookies in Morse, over an IRC channel or through DCC chat, with adjustable keying speed and Farnsworth spacing. It is easily extendable with scripts or external programs to provide additional services in Morse.
SvxLink is a flexible general purpose voice services system for ham radio use. It can act as a repeater controller or operate on a simplex channel. The server consists of a core that handles the connection to the transceiver. The transceiver audio is connected to the PC through the sound card, and the PTT is controlled by a pin in the serial port. The voice services are loaded into the core as modules. Examples of existing voice services are a help system, a module that plays back everything you say, a module to connect to other EchoLink stations, and a voice mail module. The project also includes an EchoLink client GUI application (Qtel).
gMFSK is a multimode HF terminal program that can send and receive many digital conversational modes typically used by radio amateurs on HF. It uses the computer soundcard to interface to an SSB capable transceiver. All digital signal processing is done in the main CPU so any soundcard should work.
linSmith is a Smith charting program. Users can enter either discrete components or transmission lines, see the results on screen, and/or generate Postscript output. Component values can be changed numerically or using scrollbars. Problems can be solved on-screen, and high-quality Postscript can be output for publication.
PicoStreamer is a complete server for live audio/video streaming. It can stream MP3, AAC, and video live using Flash FLV. It does not require any Flash server. It only needs a Web server with Perl and PHP. It requires neither expensive dedicated servers nor compilation on the target machine. A source client (for Win32) is included. A management/playing framework written in PHP makes PicoStreamer simple to use. The PicoIcy component acts as a local shoutcast server emulator, so you can use your preferred shoutcast source client to stream or stream Flash format directly from the Web.
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.
