# Add music to your podcast — made for this episode, not found for it To add music to a podcast in Cast, open the music lane and say what you want — a background bed that loops, an intro/outro, or a short sting — and Cast generates an original track sized to the episode. Or bring your own file. Either way it ducks under the speech on its own; nothing is searched, nothing is reused by a thousand other shows. Full answer in the docs: https://mubert.com/tools/cast/docs/generate-music ## The catalogue is the problem A track you found is a track you now have to fit: cut it to length, loop it, fade it, and ride its volume around every sentence. The fit never gets better than nearly, because the track was not made for your episode. A track generated inside the editor knows about your episode. The Match chip sizes the bed to your voice track, and once it lands on the timeline it ducks under the speech automatically — cut a minute of filler and the music re-balances itself. ## Nearly right means re-roll, not re-search When a result is close, you do not go hunting for a different track — you regenerate. And a generated track comes apart into its parts, so “the track is right but the drums are too busy” has a precise answer: re-roll only the drums, keep everything else. On Plus and Max the music carries a commercial license, and every export made on those plans ships its own license record. The price is shown next to the Generate button before you commit. - Bed, intro/outro or sting - Sized to your voice track - Ducks under speech on its own - Re-roll one part, keep the rest ## Bring your own track Already have a theme? Upload it on the Upload page tagged as Music and it lands in your Library; from there it goes on a music lane like any generated track — same auto-ducking, same level and depth controls. One catch, stated plainly: Cast licenses the music it generates, not the file you brought. Clearing a third-party track is on you. Which music, and how loud, is a craft of its own — a warm bed for an interview is the wrong bed for a narrated story, and under a voice it should sit 15–20 dB below the speech. The guides below cover the choosing and the mixing; this page covers the making. - [How to choose background music for your podcast](https://mubert.com/blog/how-to-choose-the-perfect-background-music-for-your-podcast) - [How to add intro music to a podcast](https://mubert.com/tools/cast/how-to/add-intro-music-to-a-podcast) - [Auto-ducking: music that stays under the voice after every cut](https://mubert.com/tools/cast/features/auto-duck-podcast) - [Loudness presets: export at −16 or −14 LUFS](https://mubert.com/tools/cast/features/loudness-presets) ## FAQ ### How do I generate music for my episode? Describe what you want, pick what kind of track it is — a background bed that loops, an intro/outro, or a short sting — and Cast generates an original track for the episode. It is generated for you, not pulled from a catalogue other shows are also using. More: https://mubert.com/tools/cast/docs/generate-music ### How do I add my own music? Upload it on the Upload page, tagging it as Music, and it lands in your Library. From there you can put it on a music lane in the Studio — either by picking it from the Library, or by using Replace on an existing music clip. More: https://mubert.com/tools/cast/docs/add-own-music ### Can the music fit my episode length automatically? The length, yes. When you generate a background bed, the Match chip in the Length row sets the track to your episode’s duration, instead of you guessing a length and hoping it fits. More: https://mubert.com/tools/cast/docs/match-voice ### Why does the music get quieter when someone talks? That is auto-ducking. The music drops under the voice and comes back in the gaps, automatically — and because the duck follows your actual voice clips, it stays correct after you cut. Trim a minute of filler and the music re-balances itself. You never draw a volume envelope by hand. You can set how far it drops, or switch it off.

A generated track comes apart into its parts, and you can re-roll one of them — the drums, say — without touching the rest. The parts on offer depend on the track: a gentle voiceover bed may have no drums to swap. More: https://mubert.com/tools/cast/docs/music-stems ### Is the music licensed for commercial use? Yes — music you generate in Cast comes with a commercial license on Plus and Max, and every export made on those plans carries its own license record. Free music is only free until a platform, a client or a rights holder asks where it came from; here you have a license record on file to show where the music came from. (Free and Lite have no commercial license, and music you upload yourself is yours to clear.)
