blepfx – prisma v1.0.8 for WiN

Prisma is a 3-in-1 plugin based on the Fast Fourier Transform. It is a pitch shifter that works even with polyphonic sound sources, a formant shifter, and a pitch quantizer (useful for creating the iconic sound of colored basses).

Prisma breaks the signal into tiny fragments (bins), adjusts them to the nearest frequencies within the scale, and reassembles them into an audio signal, trying to preserve the phase relationships of the original signal.

Pitch quantization is great for adding pitch to sounds or retuning them to match the key of a track. Color values ​​above 100% add additional filters on top of the pitch quantizer, which is useful for creative sound design!

Prisma is an easy-to-use formant shifter for more precise sound control. It allows you to independently change pitch and formants. Adjust the Voicing parameter to fine-tune the formant shift to your liking. Works well with vocals.

Clear sound. Clean interface. CPU-friendly:

Reduced artifacts, ringing, and CPU load compared to alternatives. Note that since this effect is FFT-based, it has a noticeable latency (approximately 85 ms at 48 kHz).
