It is a simple safe abstraction based on speexdsp.

It is available as binding or as pure-rust implementation.

By default the pure-rust implementation is used, optionally the simd-accelerated original C version can be used instead using the feature sys.

The bindings are generated using the headers and libraries that ought to be present in the system.

• Make sure you have clang and libclang installed.
• Make sure the speexdsp C headers and pkg-config files are installed.

• Source build speexdsp
• Simple bindings
• Safe abstraction
• Examples
• Clean pure-rust reimplementation

Currently we have only an integration test to compare the C and the Rust implementation. To run it issue:

$ cargo test --features=sys
