View Translation Comparison →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
python
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
python
sfx = SoundEffectsGenerator(sample_rate=44100)Tone Generation
python
# 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
python
# 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
python
# Single digit
sfx.dtmf("5", duration=200)
# Sequence (phone number)
sfx.dtmf_sequence("5551234", tone_duration=150, gap=50)Beep Sequences
python
# 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
python
# Generate silence
sfx.silence(duration=1000)Effects
python
# Fade in/out
sfx.tone(440, 2000).fade_in(200).fade_out(500)
# Volume adjustment
sfx.tone(440, 1000).volume(0.5)Chaining
python
# Combine multiple sounds
sfx.tone(440, 500) \
.silence(200) \
.tone(880, 500) \
.save("two_tones.wav")Save
python
# Save to WAV
sfx.save("output.wav")
# Save to MP3 (requires pydub)
sfx.save("output.mp3", bitrate=192)CLI Usage
bash
# 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
