Please clarify "There isn't much variety in the ones available." with regard to your assessment of Premiere Elements 12 Sound Effects. Under the Audio Tab, there are 13 categories of Sound Effects. And, the total number of free Sound Effects from those categories is 267 to 268.
Please see my blog post Premiere Elements 12 First Look blog.
Part 3. Content.
The following is an excerpt from that blog post
Sound Effects has 13 subcategories and a total of 267 or 268 free sound effects. The Sound Effects subcategories and the number of sound effects in them are Ambience (49), Animals (10), Cartoon Effects (20), Crashes (10), Fire and Explosions (18), Foley (30), Impacts (20), Industry (10), Liquids (10), Science Fiction (30), Technology (29 or 30), Transportation (11), and Weather (20).
The same Music Score and Sound Effects offerings are available in the Expert and Quick workspaces. All these files appear to be .wav files on Windows and .aiff files on Mac.
Are you not finding all that under the Audio Tab of your Premiere Elements 12?
We will be watching for your reply.
Add On...Have you updated your Premiere Elements 12 to 12.1 Update yet? If not, please do so. Thanks.
Yes, I saw all the categories...just couldn't find a few sound effects I want. (i.e. I want sound of someone whistling...I checked under cartoon sounds, but all they have under that category is balloon noises!)
Is there an option to download more? Or can you recommend a website to download effects?
Thanks for the follow up.
There are no options to download more Sound Effects from Adobe. And, if you go online beware on the links that you click on to avoid virus attacks.
If all those 200 plus sounds effects in Premiere Elements do not target the sound effect that you need, why not create your own using the Windows
Sound Recorder or with the Narration Tool of Premiere Elements (wav files)?
Have you done any Google searches for whistle sounds? Premiere Elements uses .wav Sound Effects. So, I would favor those sound effects that you find with the .wav file extension. Most of the whistles that I found online sound to me like bird noises.
