🔊 808 Sub-Bass Note Tuner & Harmonics Designer

An untuned 808 sub-bass creates mud, phase cancellation, and clashes with your melodic sample. Select your song's root key to find the exact fundamental frequency (Hz), room wavelength standing nodes, and generate upper 2nd/3rd harmonics so your 808 hits hard on phone and laptop speakers.

Root Note:

Octave Register:

Saturation Drive:

Fundamental (f₀):

43.65 Hz

Wavelength (λ in air):

7.86 m (25.8 ft)

2nd Harmonic (Octave):

87.31 Hz

3rd Harmonic (Fifth):

130.96 Hz

💡 Producer Mix Secret: Most smartphone speakers cannot reproduce below 90 Hz. Boosting the 2nd harmonic (87.3 Hz) and 3rd harmonic (131 Hz) creates the psychoacoustic illusion of deep sub-bass on tiny speakers!
