Examples with Parameters

    text="Gentle forest ambiance with birds chirping",
    duration_seconds=10.0,

    prompt_influence=0.8,
)

Output Formats

Pass output_format as a query parameter (cURL) or SDK parameter:

Format Description
mp3_44100_128 MP3 44.1kHz 128kbps (default)
pcm_44100 Raw uncompressed CD quality
opus_48000_128 Opus 48kHz 128kbps — efficient compressed

  • Specify style: "Cinematic braam, horror" or "8-bit retro jump sound"
  • Mention mood/context: "Eerie wind howling through an abandoned building"

Error Handling

python
try:
    audio = client.text_to_sound_effects.convert(text="Explosion")
except Exception as e:
    print(f"API error: {e}")

Common errors:

  • 401: Invalid API key
  • 422: Invalid parameters (check duration range, prompt_influence range)
