The bass is the part recordings hide most

Low frequencies blur into the mix, and old transfers bury them entirely. Slow the track without changing pitch and the line opens up; transpose up an octave to hear a murky note clearly, then drop it back. Loop the pocket until it is in your hands. The five-band EQ can lift the low end out of a dusty mix, and the heat map shows which fundamental is actually moving under the chord.

A detail worth knowing: walking lines reward the per-track memory — every tune reopens at your speed, on your loop. Everything else SlowBird does — the searchable library, per-track memory, the five-band EQ — is described on the main page, and the core tools in depth under slow down, looping and notes.
