The WOLFWAVE advanced audio processor already has bandpass filtering, noise reduction and age-related hearing correction. In a major upgrade, SOTABEAMS has added an effective Morse decoder that can decode signals from 1 to 100 words per minute.
In another new addition, professional musician Chris Rolinson, G7DDN, has composed a "startup" sound for WOLFWAVE, based on "WW" in Morse code. Chris' composition can be heard here: https://clyp.it/lw5qoigs
