I still use Swift for finer gradation. It also worked for video files, which was fantastic (mine never did that). Swift is 32-bit and will stop working soon. I haven't found a replacement yet.
(On iOS, at least, the 1.25/1.5/2.0 thing is because that's what the OS provides for very little effort. Finer controls require use of a supported-but-undocumented API or AudioUnits.)
