Mixing and sound effects

Mixing is not one of the three Audio Studio tools, and sound effects do not have a maker of their own. Both live in the Audio Editor, a separate surface that opens from a finished clip. Generate a voiceover, jingle, or podcast first, open it from the Library, and click Edit. That is where layers come together.

The four tabs

The editor has four tabs. Trim is a waveform where you mark the regions to keep, with fades and a master normalize pass. Transcript turns the audio into words so you can cut by deleting text instead of dragging the waveform, which is far easier than finding a phrase by its shape. Enhance is one-click voice isolation and denoise. Tracks is the mixer.

Tracks is where voice, music, and sound effects meet. You stack lanes, set gain and fades per lane, duck the music under the voice so narration stays on top, and the master comes out loudness-normalized. This is also the only place sound effects exist in the product. There is no standalone effects generator in Audio Studio; you add an effect as a lane here, while mixing an existing clip.

What is free and what bills

The deterministic passes, trimming, layering, and normalizing, are plain compute and are not billed. The passes that run a model do bill: transcription for the Transcript tab, voice isolation in Enhance, and generating a music bed inside Tracks. A pure trim and mix costs nothing; an isolation pass or a freshly generated bed does.

Because the editor works on any audio creative, treat it as the finishing step after you generate, the way you master a track only once the parts are recorded. The edited result saves as a child of the original, so your source clip stays untouched.
