    I analyzed the created waveforms with a spectrum analyzer and found that the output includes a lot of harmonics and and very wide frequency spread.
    Is there a way to influence the "quality"/spread of the created frequencies to get more distinct frequencies.
    Settings Isochronic / base frequency 220 Hz / beat 4 Hz
    gnaural 1.0 Java
    This becomes even more pronounced at lower frquencies and creating a 70Hz Isochronic beat (4 Hz) combined with a 75 Hz Alt Iscochronic appear to melt into one sound completely.
    Any ideas about that. Thanks a lot.

    "Isochronic" in this the autitory context basically means simply turning a tone on and off. The process of abruptly turning anything on and off sharply (e.g., a "square wave") will create, as Fourier shows, lots of odd-order harmonics (infinite ones, actually, in the theoretical model of a perfect square-wave).
