Hello group. Does anyone know of a programme that can produce an audio bandpass filter from a soundcard? I'm trying to find something that will allow me to specify a frequency of interest and to have the DSP remove signals above and below two cut-off frequencies. Reason: twofold, 1) I've recently recorded some EME signals from 70cms as .wav files and I'm trying to recover reasonable audio. 2) It occurs to me that the LF QRSS beacons regularly visible from VO/RU/ etc. are actually very strong and it should be possible to filter and speed up a stored QRSS file to something like normal CW........just for fun Would the new 'filter' incorporated into V2.3 spectrum Lab do this?
