For years now I've been uploading my podcasts to Soundcloud. Suddenly my latest audiofile looks weird (waves instead of vertical stripes, as you can see in the picture) and the audio quality is also much less. It's an MP3 format like I always do. The only difference is: the podcast is longer as usual (2 hours and 15 minutes). But that shouldn't be the problem right? What's going on here, who can help me?
