808 and sub bass sound design: building low end that survives a phone speaker
Most phone speakers cannot reproduce the fundamental of a deep 808, so the bass you hear on a phone is mostly its harmonics. This guide is about designing the sound itself, before mixing: picking the note, shaping the pitch drop and decay, adding harmonics on purpose, and testing on the speakers your listeners actually use.
