Jose, thanks for the report. You could also try to use my other program SDRadio for what you do, as it does have the AM, the ECSS and the FM demodulators which are absent (for the time being) from Winrad. Additionally, at least for my personal taste, the noise reduction of SDRadio works just a bit better than that of Winrad. To answer the natural question that can arise after such a statement, yes, it is in my plans to eventually transplant the SDRadio denoiser into Winrad. The algorithms are quite similar, if not identical, only a few parameters and the sampling frequency at which they operate are different. 73 Alberto I2PHD _______________________________________________ Winrad mailing list [email protected] http://winrad.org/mailman/listinfo/winrad_winrad.org
