Hear what Cast does to a raw take

Four takes with the problems every podcast has. Pick one, play Before, then After — it picks up at the same moment, and every “after” is Cast’s own output.

01

A café recording, cleaned two ways

Hum, hiss and an espresso machine under the voice. The first pass runs the Noise Remover and trims the dead air; Enhance voice goes deeper and lifts the voice off the room.

  • Noise Remover · strong
  • 4 fillers removed
  • 3 pauses shortened · −1.3 s
  • Calm Acoustic bed · style picked by the first pass, generated in Cast
The raw take, then the same lines after Cast
Before · raw take

Hi, um, so this is Episode 12, and, uh, I'm recording from the cafe down the street because, ‹ 0.8 s › um, my apartment is being painted. Ha ha ha. So if you hear, ‹ 0.9 s › uh, cups and stuff, ‹ 0.8 s › that's why.

The voices are synthetic (ElevenLabs), scripted to carry the usual problems; the café noise and the USB-mic colour were mixed in. The music is generated in Cast and mixed the way its export does it. Voice clips are level-matched to −16 LUFS, so you compare the sound, not the loudness.

Upload the raw recording and get the pro sound in a few clicks

Clean the voice

AI Noise Remover scrubs the hiss and hum; Enhance voice lifts the voice clean out of its background and levels the loudness. Cast also flags every long pause, filler and mouth sound for a one-click cut.

Edit the words

Select words in the transcript and the audio follows — cut them, mute them, or fix the wording. Chapters, speakers, pauses and fillers live in the same text.

Generate your own music

Intro, outro, transitions and beds — original music made for this episode. It matches the length you need and ducks under the voice automatically.

Export with rights

Publish with commercially licensed music — every export on a licensed plan ships its own license certificate.

We reveal the episode inside the recording.

Start editing

( problem )

Recording is the easy half. Finishing is where podcasts get stuck.

You hit stop. The conversation was good. But now there’s the part nobody looks forward to. The awkward pauses. The “uhms”. The section that should be shorter. The intro you still don’t have. The background music that sounds like every other creator used it already. The licensing question you would rather not think about.

Mubert Cast puts that last mile in one place: clean the voice, shape the episode, add music, export.

Start with your recording

We cut what gets in the way.

Clean up your audio

( How it works ! )

Drop in the recording. Walk out with an episode.

Voice Editor

Clean the mess

Find fillers, long pauses, repeated words, hesitations, and noisy moments without hunting for them manually.

Cut words, not waveforms

Edit the transcript like text. Remove a phrase, tighten a segment, fix the structure.

Music Editor

Add music to each segment

Generate background music, intros, and outros for each part of your episode. Pick the vibe; the track comes back sized to the segment and ducks under the voice.

Layer in sound effects

Drop in transitions, stingers, ambient textures, and SFX right where you need them. Fine-tune timing and volume per segment.

Export

Download the mix

One finished file, normalized to the platform you pick — Spotify, Apple Podcasts, or broadcast EBU R128.

Export stems

Vocals, music and SFX as separate tracks (Plus & Max).

We do the cleanup. You keep the flow.

( voice editor )

If you can edit text, you can edit the episode.

Waveforms are great for engineers. Words are better for everyone else.

Mubert Cast turns your recording into a transcript, so you can find the messy parts fast and clean them in context.

Delete the sentence. Cut the audio.

Or mute instead of cutting — the words drop out, the timing stays.

Shorten the dead air.

Tighten slow moments without making the episode feel chopped up.

Chapter the episode.

Find the filler words and mouth clicks.

Jump straight to "um", "uh", "like", and other verbal clutter.

Keep speakers organized.

Say who is talking once — Cast labels the rest of their lines.

Break the show into sections while the structure is still fresh in your head.

( voice cleanup )

Make the voice easier to listen to.

A good podcast does not need to sound fake-polished. It just needs to stop fighting the listener. Cast cleans up the things that pull people out of the conversation: noise, uneven pacing, long silences, mouthy bits, repeated words, and filler sounds.

Less noise

Reduce background noise so the voice sits closer.

Better pacing

Shorten the pauses that make the episode drag.

Fewer distractions

Remove fillers and repeated words when they get in the way.

You stay in control

AI helps you find the problems. You decide what gets cut.

( Music ♭♭♭ )

Stop using the stock Make your own intro.

Generate music inside the same workflow where you edit the episode.

Music is where a podcast starts to feel like a show. With Mubert Cast, you do not have to search through stock libraries, trim random tracks, or wonder whether the license will become a problem later.

The Cast editor's audio tracks: chaptered voice waveform, a generated music bed with auto-ducking, and an SFX lane

Intro music

Give the first seconds of your show a recognizable sound that listeners associate only with you.

Transitions

Move between guests with intention.

Outro music

End cleanly instead of fading.

Background beds

Add music under speech without burying it — the bed ducks when you talk.

License

Creator commercial license on Plus & Max, with a license certificate on every export.

Matched length

Generate music for the exact moment you need, down to the second, rather than forcing your edit to fit a stock loop.

( license )

The music comes with a paper trail

Music you generate in Cast comes with a commercial license on Plus and Max, and every export carries its own license certificate — the document you point at if a platform, a client or a rights holder asks where the music came from.

( who it's for )

For podcasters who care about sound, not software.

Cast is for audio-first creators who want a finished episode without learning a full DAW or stitching five tools together.

Solo hosts

Record, clean, add music, export.

One person, every role. Cast finds the fillers, generates the music, and sets the loudness — so editing stops eating the whole evening.

Interview shows

Tighten conversations without losing the natural flow.

Cut the rambling by deleting sentences in the transcript; the pauses close on their own and the chat still sounds live.

Image

Narrative podcasts

Use music and transitions to make the story feel produced.

Score every chapter with music generated for it — intro, transitions, beds under the narration — without touching a DAW.

Image

Educators and experts

Turn lectures, lessons, and long conversations into listenable episodes.

Cut the tangents in the transcript, chapter the topics, and level the loudness — a long recording becomes an episode people finish.

( export )

One file. Ready to go.

When the edit feels right and the music fits, export the finished episode as one audio file, normalized to the platform you pick — Spotify, Apple Podcasts, or broadcast EBU R128. Upload it to your host, send it to a client, or share it with your community.

FAQ

8 items

01Is Cast a podcast editor?

Yes — but the better way to think about it is a podcast finisher. It helps you clean voice, edit by transcript, add music, and export a finished audio episode.

Read more →
02Does Cast support video podcasts?

No — Cast is audio-first on purpose: there is no video timeline, and video files are rejected. Bring the audio track of your show; captions and chapters export as sidecar files you can publish alongside the video.

Read more →
03Can I remove filler words?

Yes. Hesitations — "um", "uh", "mm" — are flagged by default and you can cut them all in one click. Every cut is snapped to a quiet point in the waveform, so the edit lands between the sounds instead of through them.

Read more →
04Can I edit by transcript?

Yes — select any run of words and a menu appears: delete them (the audio is cut and the gap closes), ignore them (the audio is muted, the timing stays), correct the wording, mark a chapter, or assign a speaker.

Read more →
05Can I add podcast intro music?

Yes. 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. Once it is on the timeline it ducks under the voice automatically.

Read more →
06Is the music licensed?

Yes — music you generate in Cast comes with a commercial license on Plus and Max, and every export made on those plans carries a license certificate for each generated track. Free music is only free until a platform, a client or a rights holder asks where it came from; here you have the answer on file. (Free and Lite have no commercial license, and music you upload yourself is yours to clear.)

Read more →
07Can I upload my own music?

Yes — upload it tagged as Music and it lands in your Library, ready for a music lane in the editor. Once on the timeline it behaves exactly like generated music: it ducks under the voice automatically. Cast will not license music you brought yourself — clearing third-party tracks is on you.

Read more →
08What do I export?

A finished MP3 or WAV, normalized to the loudness of the platform you pick — exporting costs no credits, on any plan. On Max you can also switch on stems and get a ZIP of the separate parts of the mix alongside the full episode.
