To extract samples from a Soundfont file, you'll need to use a Soundfont editor. Vienna, Swami, and Polyphone are examples of such software. Once you've chosen a Soundfont editor, load the Soundfont file into the software. Most Soundfont editors or samplers will display the samples in the Soundfont file. Navigate to the samples you want to extract, select them and export them as individual WAV or AIFF files. You'll need to save the exported samples to your desired location on your computer.
