(e.g.  Hann, Lanczos, etc)\n- Functions for creating common types of FIR filters. (e.g.  low-pass, high-pass, etc)\n\nThis library was written for use in a real-time audio context. `Convolver`\nallocates all of its buffers up-front and `Forward`/`Inverse` (FFT/IFFT) operate\nin-place. This is to avoid allocations in the hot-path. I've used this library\nto implement convolution reverb and perform various types of filtering.\n\n[Usage Examples](https://godoc.org/github.com/brettbuddin/fourier#pkg-examples)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbrettbuddin%2Ffourier","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbrettbuddin%2Ffourier","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbrettbuddin%2Ffourier/lists"}
