Rain-soaked alley at midnight, distant thunder rumbling, dripping water echoing through narrow stone walls, footsteps fading away into the mist.
Abandoned subway tunnel, faint metallic creaks and echoing drips blending with low, humming air vents and faraway train rumbles
Underwater world — low rumbling currents, muffled bubbles rising, distant whale songs, a calm, otherworldly resonance.
Battlefield aftermath — faint crackle of fire, metallic debris shifting, wind carrying distant echoes of explosions and screams
Sound of a cold winter wind blowing through empty fields and forests, with distant howls and rustling trees.
Fire crackling in a quiet wooden cabin with occasional pops and the soft creak of floorboards.
Ocean waves crashing on rocky cliffs, seagulls calling, and wind sweeping through the coastline.
Medieval blacksmith hammering metal, fire roaring, and the sound of steel cooling in water.
Forest at dawn filled with chirping birds, rustling leaves, and distant animal calls.
Gun being reloaded with metallic clicks, followed by a single gunshot echoing in an open field.
Generate cinematic sound effects directly from text. Describe the scene or action, and Kling creates matching foley, ambience, risers, booms, whooshes, and textures—perfect for trailers, shorts, games, podcasts, and multimedia projects.
Describe what you want to hear. Example: Cold winter night with howling wind across barren fields; deep gusts; distant creaks; approaching snowstorm tension.

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/kwaivgi/kling-text-to-audio with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Kling Text To Audio below.

Kling Text-to-Audio turns text prompts into custom sound effects for videos, games, and multimedia using KlingAI's audio model. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/kwaivgi/kwaivgi-kling-text-to-audio.
Kling Text To Audio starts at $0.035 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
Key inputs: `prompt`, `duration`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/kwaivgi/kwaivgi-kling-text-to-audio.
Average end-to-end generation time on WaveSpeedAI is around 20 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.
Commercial usage rights depend on the model's license, set by its provider (Kuaishou). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
