Does this sound like S3, or just wide split S2?

I am not sure, but it sounds interesting. Recorded about Erb's point while lying on the stomach. There is also a little whooshing noise? What do you think?

I think I hear a split S1. Using youtube's x0.5 playback speed makes it more obvious, and you can see it in the sonogram. Not sure about S2 - it sounds longer than usual, but not sure if it's split or an early diastolic murmur.

[footnote]

I listened to your recording attentively. Your heart sounds are beautifully strong and interesting indeed. However, this recording sounds more like a split S2 rather than an S3. And S3 is very distinct at the end, like a recoil, and has the rhythm of when you speak out the word Kentucky. It can be best heard at apex or point of maximum impulse when you lay down on your left side. My heart has an S3 that can be heard as example in my videos.
