//! Iced Audio is an extension to the [`Iced`] GUI library with useful widgets //! for audio applications such as VST / LV2 plugins. //! //! # Installation //! //! Add `iced_audio` as dependency in your `Cargo.toml`: //! ```toml //! iced_audio = "0.7" //! ``` //! Or if you want to use the GitHub version of `iced`: //! ```toml //! iced_audio = { git = "https://github.com/BillyDM/iced_audio", branch = "iced_git" } //! ``` //! __Both Iced Audio and [Iced] move fast and the `main` and `iced_git` branch can contain breaking changes!__ If //! you want to learn about a specific release, check out [the release list]. //! //! # Simple Usage Example //! //! This crate assumes you know the basics of how to use [`Iced`]. If you //! haven't alreay, please check it out [`here`]. //! //! ```no_run // Import iced modules. //! use iced::{ //! Align, Column, Container, Element, Length, Sandbox, Settings, Text, //! }; //! // Import iced_audio modules. //! use iced_audio::{ //! h_slider, knob, tick_marks, v_slider, xy_pad, FloatRange, FreqRange, //! HSlider, IntRange, Knob, LogDBRange, Normal, VSlider, XYPad, //! }; //! //! // The message when a parameter widget is moved by the user //! #[derive(Debug, Clone)] //! pub enum Message { //!
