Crate fundsp

Expand description

FunDSP is an audio processing and synthesis library.

See README.md in crate root folder for an overview. For a list of changes, see CHANGES.md in the same folder.

The central abstractions are located in the audionode and audiounit modules. The combinator module defines the graph operators.

Constants§

DEFAULT_SR: Default sample rate is 44.1 kHz.

simd_items: Convert amount from samples to (full or partial) SIMD elements.

Type Aliases§

F32x: Blocks are explicitly SIMD accelerated. This is the type of a SIMD element containing successive f32 samples.
I32x: The 32-bit signed integer SIMD element corresponding to F32x.
U32x: The 32-bit unsigned integer SIMD element corresponding to F32x.
