FAQ

  • What is tremolo?

    A steady rise and fall in volume that adds a pulsing, rhythmic motion.

  • How is it different from Vibrato?

    Tremolo pulses the volume up and down, while Vibrato wobbles the pitch — use tremolo for a rhythmic, throbbing motion.

  • What does the depth control?

    A light setting adds gentle movement, while a deeper one turns the pulse into a clear, hypnotic throb.

Supported Formats

Input: audio/video. Output: MP3, WAV, OGG, FLAC, M4A, MP4.

What the tremolo effect does

It moves the volume up and down at a steady rate, adding a smooth, pulsing rhythm to the sound. The motion is felt more than heard as a change in tone.

Subtle motion or deep pulse

A light setting adds gentle movement and life. A deeper one turns the pulse into a clear, hypnotic throb for retro and atmospheric moods.

Tips

  • Sustained sounds and pads show the pulse most clearly.
  • Subtle tremolo keeps voiceovers lively without distraction.
  • Combine with Vinyl for a warm, vintage character.
