vdisk~ uses [readsf~] in conjunction with [block~] and [tabwrite~] to read a file from disk at any pitch/speed.
Usefull for situations where you need to load very quickly any soundfile from any folder and want to read them at any pitch.
I made this because I needed it and some externals such as [sfread2~] from moonlib tended to crash pd on my system, so I decided it wasn't reliable.
