FAQ

  • What does the chorus do?

    It layers slightly detuned copies to make one voice sound fuller and wider.

  • Will it blur speech?

    Keep it moderate on voices so words stay crisp; thin leads and vocals gain the most body, and you can layer Shimmer for extra width.

  • How is it different from Shimmer?

    Chorus Fat thickens and widens the sound with detuned copies, while Shimmer adds bright treble and a glassy sparkle on top.

Supported Formats

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

What the fat chorus effect does

It stacks several slightly detuned, delayed copies of the sound, so a single voice becomes thick, wide and lush. The result feels bigger without changing the words.

Gentle width or full ensemble

A soft setting adds a tasteful spread and richness. A stronger one builds a shimmering, ensemble-like wall of sound.

Tips

  • Thin voices and leads gain the most body from a chorus.
  • Keep it moderate on speech so words stay crisp.
  • Layer with Shimmer for an even wider, glassier tone.
