I learned about SoundSoap just in time to avoid a disaster. Here's the backstory that involves the two videos above. When Dennis (who shot the videos) and I got back from the Pepcom Spring event and uploaded the videos we were in for a big surprise. I had used an older mic with the much newer Galaxy S6. You can do that with no problem as long as you insert a special dongle between them. (It does something important like changing the way audio connections are wired between the two devices.) Without that dongle, the Galaxy S6 not only records the external Audio Technica mic audio, it also records all the unwanted and loud background noise via the built in phone mic. So for a while we thought the videos for the Waspcam & the Kube+Clock above were totally unusable. (We couldn't reshoot them because Pepcom is a one-time 3 hour event.) But after doing some quick research online I found out about Sound Soap and it saved the day. (And the two videos.) All I did was open the media to be cleaned in SoundSound and I let it adjust the settings. Then I saved the results in a different file than the source video. Its was that easy! They were more adjustment that could be made but I was happy just to know I could use our two videos. SoundSoap works on Mac OS X or Windows 7/8/10 as a standalone application or a plug-in. The company says it supports most popular media file formats. I used SoundSoap5. There's a more advanced version called SoundSoap5+ which allows for more adjustments. The plug-in version is $79.99 and the full desk version is $149.99. There's more info on the company webssite.
Here's a quickie Giz Wiz video demo: The first 10 seconds of the video is the way it was recorded. The second 10 seconds is the result after SoundSoap Software automatically cleaned it up enough for us to use.
