Q: I recorded my podcast intro and outro separately. How do I merge them?
A: It's surprisingly annoying to do this on a phone. That's why this tool exists.
You literally just upload File A (your intro), and then upload File B (the main podcast body). The digital tool aggressively glues the end of File A directly to the precise beginning of File B without losing a single millisecond of quality. It takes exactly three seconds.
Q: Does joining two songs together create a nasty pop sound where they meet?
A: It absolutely can, if you aren't careful. If you violently cut a drum beat exactly in half and glue it to a totally different song, your speakers will audibly click.
The safest bet is to ensure both songs fade out totally to silent zero before they join. Or, actively use the crossfade option to smoothly blur the two tracks together so you never hear the hard digital cut.
