engine from the Sony S-SMP audio processing unit in the
[Super Nintendo Entertainment System (SNES)][SNES]. The sample playback engine
has a compression ratio of _32:9_ over standard 16-bit PCM, and includes a
reconstruction filter.
Super VCA is an emulation of the BRR filter & Gaussian interpolation filter
from the Sony S-SMP audio processing unit in the

audio inputs and outputs of the module are locked to _32kHz_.
- **Multi-channel Processing:** 8 different mono sample playback channels.
- **Stereo Panning:** Split mono samples into the stereo field and introduce
surround sound effects.
- **Reconstruction Filter:** Four-mode reconstruction filter including a
bypass mode and three low-pass filter modes.
Super VCA provides the key features of the BRR filter and Gaussian filter
of the S-SMP chip, namely,
- **Stereo Processing:** Dual processing channels for stereo effects or other

- **4 BRR Filter Modes:** 4 filter modes from the BRR sample playback engine
that act as low-pass filters.
- **Gaussian Interpolation Filter:** A filter that removes high-frequency
content and adds subtle distortion. This filter provides the muffling
character that fans of SNES audio will find familiar.

Each voice produces an output signal of at most $10V_{pp}$ when the amplifier is maxed out. The individual oscillators cannot be overdriven to produce clipping, distortion, or aliasing. However, outputs are normalled forward into a sum mix where hard clipping \textit{can} occur. Excess clipping will introduce an aliasing effect to the mix.

When the \textbf{ENV} switch is pointing up, the global envelope generator is enabled for the voice. When pointing down, the noise generator is disabled for the voice.
