Most audio and video types this browser can play — MP3, WAV, M4A, AAC, FLAC, OGG, MP4, WebM, MOV, and similar. If this browser cannot decode a file, the kit will say so.

Why might OGG be missing?

Not every browser can write OGG here. WAV and MP3 still are.

Does convert change the sound?

WAV keeps the samples as they are. MP3 and OGG compress, so a little detail can go.
