Stable Audio 2.5Pixio audio systemBuilt for structured audio generation

Stable Audio 2.5

Create or transform audio: text-to-audio, inpainting (edit parts of a clip), or audio-to-audio for sound design and music.

Pixio read

Audio prompts work best when they define mood, pacing, structure, and finish. The more clearly you describe the role of the sound, the cleaner the result tends to be.

Best results start with genre, mood, structure, and arrangement.

How to get the best out of Stable Audio 2.5

Compose
Best when the composition, mood, and arrangement need to come together from one brief.
Songs, instrumentals, background music, cue generation.
Structure
Best when you define pacing and sections instead of vague genre labels.
Hooks, transitions, timing, emotion, arrangement logic.
Refine
Best when the source audio is useful but needs cleanup, transformation, or separation.
Stem work, edits, polish passes.
Basic Info

Stable Audio on Pixio (e.g. Stable Audio 2.5) lets you create or transform audio: text-to-audio, inpainting (edit parts of a clip), or audio-to-audio for sound design and music. Use it when you need prompt-driven music or sound design with the option to edit existing clips (inpaint) or transform them (audio-to-audio).

Stable Audio

Stable Audio on Pixio (e.g. Stable Audio 2.5) lets you create or transform audio: text-to-audio, inpainting (edit parts of a clip), or audio-to-audio for sound design and music. Use it when you need prompt-driven music or sound design with the option to edit existing clips (inpaint) or transform them (audio-to-audio).

Use this when

  • You need text-to-audio for music or sound design (describe genre, mood, length).
  • You want to edit part of a clip (inpainting)—replace or fix a segment without re-generating the whole thing.
  • You need audio-to-audio (transform an existing clip with a prompt—style, mood, or content change).
  • You are building sound design, background music, or SFX with Stable Diffusion-style control.

Prompt demo
Melancholic synth-pop cue, slow build, wide chorus, analog bass, glassy pads, cinematic mix with restrained low end and late-night mood.

A strong audio prompt describes role, pacing, tone, and finish so the output feels produced rather than generic.

Modes and controls
Direct the arrangement
Compose

Describe the genre, emotional arc, instrumentation, and structure instead of relying on broad tags alone.

Tips

  • Clear prompt: genre, mood, instruments, and length (e.g. "dark ambient, 60s, pads and subtle percussion").
  • Inpainting when you need to fix or replace a section of an existing clip.
  • Audio-to-audio for style transfer or mood change on an existing track.
Open Generate
1

Use production language, not just genre labels.

2

Tell the model how the energy should move over time.

3

For speech, define delivery style, tone, and pacing.

4

For music, define arrangement and emotional arc early.

Shape the timing
Structure

Define how the piece should progress so the output feels intentional instead of flat or repetitive.

Polish the source
Refine

Split, edit, or reshape useful material rather than rebuilding the whole asset from nothing.

Best use cases
1

Stable Audio 2.5 is strongest when the brief is clear about function: what the sound should do, how it should move, and what it should feel like.

2

Use structure language early so the output lands closer to production-ready on the first passes.

3

For voice work, specify delivery and character. For music, specify arrangement and emotional progression.

Pixio workflow
Step 01
Define the role

Decide whether the output is carrying narrative, mood, rhythm, or all three.

Step 02
Direct the pacing

Describe the build, energy, and transitions so the result has movement instead of flattening out.

Step 03
Polish the usable take

Once the direction is right, refine and separate instead of regenerating blindly.

Best paired with
Voice Clone

Pair voice generation with cloning when continuity across campaigns or characters matters.

Video models

Use generated music or speech as the finishing layer once the visual cut is already working.
