While looking for so info on audio apps I ran across this site that seems to have a small but good collection of a number of different projects and DOS programs... these may be of interest to some folks of the group so I am passing this along. The web addy is:
http://www.qsl.net/dl4yhf/The DOS programs are as follows:
Spectrum Lab - a tool for audio analysis, DSP, beacon logging, etc.
WOLF GUI - a graphic user interface for Stewart Nelson's WOLF (Weak-signal Operation on Low Frequency)
Sound-Utilities - read from the soundcard's ADC and send to DAC
Audio I/O library - exchange audio in real time between different applications (also for audio streaming using winamp / oddcast)
CalcEd - a text editor which calculates with complex numbers !
CurveEdit - a primitive, graphical viewer / editor for array data ("curves")
PIC programmer - DL4YHF's WinPic for Win95+98+XP, uses LPT or COM1..4, and supports a variety of PIC microcontrollers.
RDF Calculator: for radio-direction finding, topographic map display, GPS track display, etc
There are a number of other things including one that has caught my interest is his QRP Indoor Loop that uses a standard tuning capacitor instead of a 'butterfly' cap.
I hope this might be of interest to the group.
