The Soundbox studio

Writing

Give the script room and close everything else. The lines hold their place on the timeline while you write them, before any of them is voiced.

Arranging

Both columns closed and the timeline across the full width. The timeline is a panel like the others and can be closed too, for example while you write.

Mixing

The device rack on the right, per track. There are eight kinds (compressor, eq, reverb, delay, distortion, gate, limiter and autotune), so the narration lane can be compressed while the music under it is ducked.

On a narrow screen

Below the layout's breakpoint the columns stop flanking the timeline and stack under it. The same panels stay open, in one column instead of three.

extend

The source unchanged, followed by new material up to the target length. Extend is a repaint whose window starts past the end of the clip, so the source survives sample for sample.

cover

The clip re-rendered in the style of a new prompt, locked to the source's length. A strength setting decides how closely it follows the original.

repaint

Regenerate a window inside the clip and keep both edges. Use it when one moment in an otherwise good take is wrong.

separation

Split a mix into stems. htdemucs gives vocals, drums, bass and other. Separation is a task mode of its own, separate from generation. It needs 44.1 kHz, so Soundbox resamples first.
