Wav sound files typically have names that attempt to suggest what they sound like. But keep in mind it's just a name: a file named moo.wav may actually make a bell ringing sound when it's actually played. After downloading, rename the file to the sound name expected by your template code.
Copy the sound file to the ScoutPalDB database location on your pda's data card, then use the Pocket PC File Explorer program to find and then tap on the sound file. The PDA's Media Player program should then play the sound, over and over again, if you like. This test procedure is to be sure that the sound can be played on your particular Pocket PC, as some devices are not able to play certain peculiar sound files.
Most boilerplate templates look for a sound file named "ding", and this ding file gets updated to its default sound after each weekly DB Update process. So after each DB update, you will need to replace the ding file with your custom one. Better yet is to edit the code inside your template file (using the Notepad program on a Windows computer) so that it instead looks for a completely different sound file name. Copy and paste a working copy of your spdbtemplate file from your datea card to your computer, edit it to change its sound file name reference, then put it back on the card. You can also directly edit the template file while it's in the data card, while the card is plugged into your computer, although making a backup copy first is recommended. After you change your template to look for a different particular sound file name, name your downloaded sound file accordingly.
For example, suppose you are using the template titled "Play Ding Wav If Lowest Gt 7 And Rank Lt 2500k". Save your sound file with a unique and different name (for example, 'mysound' or some other unique name) and edit your template change its internal reference to a 'ding.wav' to be 'mysound.wav' instead.
Click on a sound file below to hear it play on your computer. If you like the sound and want to get a copy, right-click on its name, then select "Save Link/Target As..." (the exact wording will depend on your type of browser, e.g. chrome, firefox.) You will be given a chance to alter its name, and more importantly, to choose the location on your computer where it will get saved. Choose a place that you know how to get to, like on the desktop, or in a downloads folder. Name it to match your template's sound file name requirement now, or you can do that later, it doesn't matter until it gets copied into the data card in the same folder with the template and the database files. (For 99% of users: this will be a folder named "spdb2" on the root of the storage card.)
To test a template, tap in "x42" instead of an ISBN. The ScoutPalDB program will then bring up random books from the database, each time you tap "seek", so you can quickly see how a template will work with various price/rank scenarios.
