SubRingFM is a dynamic ring modulator plugin designed to create unique and complex sounds. It features two filters that allow precise shaping of the audio signal, providing control over both the input and output tonal characteristics. Additionally, it includes a sub-octave generator that enriches the sound by adding lower frequency content, enhancing depth and presence.

The signal path begins with a pre-filter that helps to reduce unwanted harmonics from the input, preparing the sound for modulation. The core of the effect is the ring modulator, which utilizes an FM oscillator to produce intricate frequency combinations. This approach enables the creation of rich and evolving textures, making it suitable for a wide range of musical styles and sound design applications.

After modulation, the signal passes through a post-filter that further sculpts the tone, allowing for fine-tuning of the complex output. The final stage adds the sub-octave generator, which adds depth and weight to the sound. Together, these features offer extensive creative possibilities for crafting distinctive and powerful audio effects.
