Flutter 的低级音频插件。

概述

一款高性能音频插件，主要为游戏和沉浸式应用设计，提供低延迟和高级功能。

主要特色

• ⚡ 低延迟，高性能音频
• ⏱️ 采样精确的计划播放：playClocked 用于亚毫秒间隔的播放，无论缓冲区大小如何;playScheduled 用于在引擎自身时钟上调度整批声音的乐谱/清单式排程（可选定定时停止/淡出）。非常适合节拍器、音乐序列器、节奏游戏和精确定时的音频提示
• 🎮 带有多普勒效应的3D定位音频
• 🔄 半开start, end)环区的无间隙环路
• 🔄 带自动暂停缓冲功能的音频流式流，支持PCM、MP3、WAV、FLAC、Ogg（Opus、Vorbis、FLAC）、AAC（ADTS）、AC-3和E-AC-3（注：MP4和M4A不支持流媒体）

A low-level audio plugin for Flutter.

Overview

A high-performance audio plugin designed primarily for games and immersive applications, providing low latency and advanced features.

Key Features

• ⚡ Low latency, high performance audio
• ⏱️ Sample-accurate scheduled playback: playClocked for sub-millisecond spaced playback regardless of buffer size, and playScheduled for score/manifest-style scheduling of whole batches of sounds on the engine’s own clock (with optional scheduled stop/fade). Perfect for metronomes, music sequencers, rhythm games and precisely timed audio cues
• 🎮 3D positional audio with Doppler effect
• 🔄 Gapless looping with half-open [start, end) loop regions
• 🔄 Stream audio with auto-pause for buffering, support for PCM, MP3, WAV, FLAC, Ogg (Opus, Vorbis, FLAC), AAC (ADTS), AC-3, and E-AC-3 (Note: MP4 and M4A are not supported for streaming)
• 📥 Pull-buffer streaming: the engine requests encoded data on demand (MP3, WAV, FLAC, Ogg Opus/Vorbis/FLAC, AAC ADTS, AC-3, E-AC-3), with seek support and callbacks for buffering, metadata, duration and data requests — ideal for network streams and custom data sources
• 🚌 Mixing buses: group voices (music, SFX, UI…) into sub-mixes with their own volume, filters and visualization
• 📊 Get audio wave and/or FFT audio data in real-time (useful for visualization)
• 🎛️ Rich effects system (reverb, echo, limiter, parametric equalizer, pitch shift, ring modulation, etc.)
• ⚙️ Faders for filter attributes (e.g. fade out for 2 seconds, then stop)
• 🎚️ Oscillators for filter attributes
• 🌊 Waveform generation and visualization
• 🔊 Multiple voices, playing different or even the same sound multiple times
• 🎵 Audio playback support for MP3, WAV, OGG, FLAC, plus native platform decoding for M4A, MP4 (audio tracks), AAC, AC-3, and E-AC-3
• 🔴 Capture the master mixer output as a stream for recording, processing, or streaming (with different PCM formats and Opus, Vorbis, FLAC, WAV encoded stream formats)
• ⏱️ Read audio data samples from a file with a given time range
• 🌊 Generate waveforms in real-time with various types (sine, square, saw, triangle, etc.)
