I think you want to try this:
Select the middle keyrames(the keyframes in between the first and last keyframes), then:
Animation>Keyframes Interpolation
and change the dropdown in the “Roving” box to “Rove Across Time”
Search forr roving keyframes in the AE Help, those roving keyframes can be very handy sometimes.

This may be what you want.

Adobe has some great After Effects Tuts at their Support sit:
https://studio.adobe.com/us/search/main.jsp
Just select “After Effects” from the Product Drop Down (middle of the page), and leave “All” in the Topic, Content Type, and Level boxes. This will bring up the Adobe tuts.
Two of them do what you want to do with – Animation>Keyframe Assistant>Convert Audio to Keyframes.Using Music to Animate Text
https://studio.adobe.com/us/tips/tip.jsp?p=1&id=396&xml=aft6audio
Let Sound Drive the Motion
https://studio.adobe.com/us/tips/tip.jsp?p=1&id=100172&xml=aft6ttsound
This one is better taking you through the process step by step, and at the end showing you how to tweak the expression to get the amount of change you want.
Trapcode’s Sound keys is great, but this native AE feature will do quite a bit too.

Once you get the Shatter part down you can do tweaks, like Scatter (for smaller particle) and glow – my two favs, change the color, or whatever looks good to you.

You might try Windows Media Encoder:
https://www.microsoft.com/windows/windowsmedia/9series/encoder/default.aspx
It’s free. There is a little learning curve, but I too a 720×480 down to 480×360 (both 29.97, 90 sec long down to 6.5 MB (506 kbps) from a 1.2 GB Uncompressed avi. Try the “DVD quality 1 Mbps” or “VHS quality 250 kbps” (about 2 steps into encoder), then modify from there as need be. If the file comes out too big, click the “Properties” on the tool bar, then the “Compression” tab, then “Edit” button, and change the codec, or click on the tab that says how many “_____ Kbps” (only other tab on top), there you can directly change the video and audio bitrate, the fps, and the video size. With a little trial and error, depending on you last results, you get down to where you want to go pretty easily. Also in properties go to “Output” tab and change the name of the output file.
WMEncoder is 2 pass variable bitrate, and though some people are crazy about the “soft” look at low bitrates, I like it.Anyway, it might be worth a try for you.

Advanced search for “exponential expression” yielded this for scale:
https://forums.creativecow.net/cgi-bin/new_read_post.cgi?forumid=2&postid=703921&archive=T
Dan Ebbert’s last post in the series gives an expression for an exponential curve between two keyframes and the original poster said it did the job. When I have free time, I just search for Dan’s name and expressions and always turn up interesting posts.
