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....
