Preset data file created by SampleTank, a sound sample creation application; created with .STH and .STI files; contains the instrument waveforms for audio output for the Instrument User Preset .STIP file; must remain in the same folder as the related STH, STI, and STIP files; not meant to be manually opened.

For every STIP file created, an STH, STI, and STW file will be created. Each of the three files contain data the STIP draws from. To create a STW file, edit your sound in the application, click SAVE in the User Preset area, name your sound, click OK, this creates a STIP file which also creates the STW file and will be located in the folder of its "Parent Sound." The related STH, STI, and STIP files will all be named after the same instrument. If your instrument is called, "Clarinet," then your STW file will appear like this: Clarinet.stw.
