  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads sound-effects-generator automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

Sound Effects Generator

Generate programmatic audio: pure tones, noise types, DTMF signals, and simple sound effects. Perfect for testing, alerts, audio cues, and placeholder sounds.

Quick Start

from scripts.sfx_generator import SoundEffectsGenerator

# Generate a tone
sfx = SoundEffectsGenerator()
sfx.tone(440, duration=1000).save("a440.wav")

# Generate white noise
sfx.noise("white", duration=2000).save("whitenoise.wav")

# Create a beep sequence
sfx.beep_sequence([440, 880, 440], durations=200, gap=100).save("alert.wav")

Features

  • Tones: Sine, square, sawtooth, triangle waveforms
  • Noise: White, pink, brown/red noise
  • DTMF: Phone dial tones
  • Sequences: Multi-tone patterns
  • Effects: Fade, volume control
  • Export: WAV, MP3

API Reference

Initialization

sfx = SoundEffectsGenerator(sample_rate=44100)

Tone Generation

# Pure sine wave
sfx.tone(frequency=440, duration=1000)

# Different waveforms
sfx.tone(440, duration=1000, waveform="sine")      # Default
sfx.tone(440, duration=1000, waveform="square")
sfx.tone(440, duration=1000, waveform="sawtooth")
sfx.tone(440, duration=1000, waveform="triangle")

# With volume (0.0 to 1.0)
sfx.tone(440, duration=1000, volume=0.5)

Noise Generation

# White noise (equal energy all frequencies)
sfx.noise("white", duration=2000)

# Pink noise (1/f, natural sounding)
sfx.noise("pink", duration=2000)

# Brown noise (1/f^2, deeper)
sfx.noise("brown", duration=2000)

# With volume
sfx.noise("white", duration=1000, volume=0.3)

DTMF Tones

# Single digit
sfx.dtmf("5", duration=200)

# Sequence (phone number)
sfx.dtmf_sequence("5551234", tone_duration=150, gap=50)

Beep Sequences

# Single beep
sfx.beep(frequency=800, duration=200)

# Multiple beeps (same frequency)
sfx.beep_sequence([800, 800, 800], durations=100, gap=100)

# Melody (different frequencies)
sfx.beep_sequence([523, 659, 784, 1047], durations=200, gap=50)

# Varying durations
sfx.beep_sequence(
    frequencies=[440, 880],
    durations=[300, 500],
    gap=100
)

Silence

# Generate silence
sfx.silence(duration=1000)

Effects

# Fade in/out
sfx.tone(440, 2000).fade_in(200).fade_out(500)

# Volume adjustment
sfx.tone(440, 1000).volume(0.5)

Chaining

# Combine multiple sounds
sfx.tone(440, 500) \
   .silence(200) \
   .tone(880, 500) \
   .save("two_tones.wav")

Save

# Save to WAV
sfx.save("output.wav")

# Save to MP3 (requires pydub)
sfx.save("output.mp3", bitrate=192)

CLI Usage

# Generate tone
python sfx_generator.py --tone 440 --duration 1000 --output tone.wav

# Generate noise
python sfx_generator.py --noise white --duration 2000 --output noise.wav

# Generate DTMF
python sfx_generator.py --dtmf "5551234" --output phone.wav

# Generate beep pattern
python sfx_generator.py --beeps "800,800,800" --duration 100 --gap 100 --output alert.wav

# With waveform
python sfx_generator.py --tone 440 --waveform square --duration 1000 --output square.wav
