Wow Flutter
An effect that adds subtle pitch variations to your music, similar to the natural wavering sound you might remember from vinyl records or cassette tapes. This creates a warm, nostalgic feeling that many people find pleasing and relaxing.
Listening Experience Guide
- Vinyl Record Experience:
- Recreates the gentle wavering of turntables
- Adds organic movement to the sound
- Creates a cozy, nostalgic atmosphere
- Cassette Tape Memory:
- Simulates the characteristic flutter of tape decks
- Adds vintage tape deck character
- Perfect for lo-fi and retro vibes
- Creative Atmosphere:
- Creates dreamy, underwater-like effects
- Adds movement and life to static sounds
- Perfect for ambient and experimental listening
Parameters
- Rate - How fast the sound wavers (0.1 to 20 Hz)
- Slower (0.1-2 Hz): Vinyl record-like movement
- Medium (2-6 Hz): Cassette tape-like flutter
- Faster (6-20 Hz): Creative effects
- Depth - How strongly the delay time is modulated, which makes the pitch waver (0 to 40 ms)
- Subtle (0-6 ms): Gentle vintage character
- Medium (6-15 ms): Clearly audible tape/vinyl feel
- Strong (15-40 ms): Dramatic special effects
- Ch Phase - Phase difference between stereo channels (-180 to 180 degrees)
- 0°: Both channels waver together
- 90° or -90°: Creates a swirling, rotating effect
- 180° or -180°: Channels waver in opposite directions
- Randomness - How irregular the wavering becomes (0 to 40 ms)
- Low: More predictable, regular movement
- Medium: Natural vintage variation
- High: More unstable, worn equipment sound
- Randomness Cutoff - How quickly the random changes happen (0.1 to 20 Hz)
- Lower: Slower, more gentle changes
- Higher: Quicker, more erratic changes
- Randomness Slope - Controls how aggressive the randomness filtering is (-12 to 0 dB)
- -12 dB: Smoother, more gradual random variations (gentler effect)
- -6 dB: Balanced response
- 0 dB: Sharper, more pronounced random variations (stronger effect)
- Ch Sync - How synchronized the randomness is between channels (0 to 100%)
- 0%: Each channel has independent randomness
- 50%: Partial synchronization between channels
- 100%: Both channels share the same randomness pattern

Quick Start Guide
- For a Natural Vintage Sound:
- Start with slow Rate (0.5-1 Hz)
- Add light Depth (2-6 ms)
- Include a little Randomness (1-4 ms)
- Use Randomness Cutoff around 0.5-3 Hz
- Keep Ch Phase at 0° and Ch Sync at 100%
- Adjust to taste
- For More Character:
- Increase Depth gradually
- Add more Randomness
- Experiment with different Ch Phase settings
- Reduce Ch Sync for more stereo variation
- Trust your ears
Remember: The goal is to add pleasant vintage character to your music. Start subtle and adjust until you find the sweet spot that enhances your listening experience!
