For anyone that needs to generate or analyse audio files for testing Software Defined Radios and similar, I've placed a number of wav file synthesis and analysis progs on my website in the software download section. Direct access www.scrbg.org/g4jnt/WAVDSP.ZIP
WAVDSP.ZIP contains, amonsgt others, a programme up upconvert multiple source files into one large wide bandwidth stereo I/Q (complex) file with adjustable frequency and time shifts, and amplitude weighting. The target file is aimed at image reject upconversion to RF, allowing the SDR transmit (or receive after upconversion) process to be tested on wideband multiple carrier signals.
A PSK31 generation utility generaes wav files for specified PSK31 message; CW message to audio generation is also included, as well as FSK, QPSK, tone generation, parallel tone testing .WAV file and I/Q file analysis. Further details are given in WAVDSP.TXT, now included in the archive.
