Prisma is an advanced audio plugin that offers three powerful tools in one: pitch shifting, formant shifting, and pitch quantization. It excels at processing polyphonic audio sources, making it suitable for a wide range of instruments and vocals. The pitch shifter can adjust the tone from one octave below to one octave above the original pitch, delivering clean and natural results. This flexibility allows users to creatively transform their sounds without sacrificing clarity.

At its core, Prisma uses a phase vocoder approach, breaking the audio signal into small frequency bins to manipulate pitch and formants while preserving the original phase relationships. The formant shifter enhances vocal and instrumental textures by enabling fine control over voicing characteristics, which helps maintain natural timbre during pitch alterations. Additionally, the pitch quantizer locks pitches to musical scales, with a dedicated control to add a distinctive color and warmth, ideal for crafting unique bass tones.

Designed with efficiency in mind, Prisma features optimized algorithms that reduce CPU load without compromising sound quality. Although based on FFT processing, which introduces some latency, the plugin minimizes artifacts and preserves audio transients for a clean output. Its minimalistic and resizable interface allows users to quickly access essential controls and achieve desired results with ease, making it a practical choice for producers seeking high-quality pitch and formant manipulation tools.
