 # Discord Audio Stream
 
 [![npm](https://img.shields.io/npm/dw/discord-audio-stream)](http://npmjs.org/package/discord-audio-stream)
-![GitHub package.json version](https://img.shields.io/github/package-json/v/FrauJulian/discord-audio-stream)
+![latest release](https://img.shields.io/badge/dynamic/json?label=release&query=$.name&url=https%3A%2F%2Fapi.github.com%2Frepos%2FFrauJulian%2Fdiscord-audio-stream%2Freleases%2Flatest&color=blue)
 ![GitHub Repo stars](https://img.shields.io/github/stars/FrauJulian/discord-audio-stream?style=social)
 
-**This module is designed to work with [discord.js/voice](https://www.npmjs.com/package/@discordjs/voice) v0.19. This
-package doesn't support older
-versions!**
+> **Designed for 24/7 Discord audio playback.**  
+> `discord-audio-stream` is a small TypeScript library for managed Discord voice playback through
+> `@discordjs/voice` and ffmpeg.
 
-> **Designed for 24/7 audio playing on discord.**  
-> Discord has many unwanted rate limits, especially in the audio area. This package does all the work and ensures that
-> your music never stops playing due to ffmpeg or Discord, with as little effort as possible.
+Discord voice streams need careful lifecycle handling. This package manages the voice connection, ffmpeg process,
+raw PCM resource creation, optional reconnect renewal, and predictable cleanup so your bot code stays small and readable.
 
-> **Recommended best Practise:**  
-> Create a global Map<GuildId, AudioManager> (Map<KEY, OBJ>) list. When the feature is used on a guild, add a new
-> instance of AudioManager to the Map. When starting the connection or audio, overwrite the respective configuration with
-> the override methods provided. To finally start, use the respective method. For each call and each change, retrieve the
-> AudioManager object from the list and perform your actions. When the feature get stopped, first execute StopConnection
-> and then Dispose to save as much power as possible. Garbage collection does the rest.  
-> **For large systems:** For large systems, it is recommended to queue each start with the
-> packet [p-queue](https://www.npmjs.com/package/p-queue), to give ffmpeg enough time..
+> **Recommended best practice:**  
+> Keep one `AudioManager` per guild, usually in a `Map<string, AudioManager>`. Update the connection or source through
+> `setConnection()` and `setSource()`, then call `start()`. When playback stops, call `stop()`. When the manager will not
+> be reused, call `dispose()` to release timers, streams, ffmpeg, and the voice connection.
+
+> **For large bots:**  
+> Queue many simultaneous starts, for example with [`p-queue`](https://www.npmjs.com/package/p-queue), so the host does
+> not spawn too many ffmpeg processes in the same tick.

 ## 📝 Usage
 
 ### Installation
 
-**Node.js 22.12.0 or newer is required.**
+**Node.js `22.12.0` or newer is required.**
+
+Install the library and the required voice packages:
 
 ```bash
-npm install discord-audio-stream
-yarn add discord-audio-stream
-pnpm add discord-audio-stream
-bun add discord-audio-stream
+npm install discord-audio-stream @discordjs/voice prism-media @snazzah/davey opusscript
 ```
 
-#### Required Dependencies
+`libsodium-wrappers` is optional. Install it only when your runtime does not support `aes-256-gcm`:
 
-- > You only need to install `libsodium-wrappers` if your system does not support `aes-256-gcm` (verify by running
-  > `require('node:crypto').getCiphers().includes('aes-256-gcm')`).
-- `@snazzah/davey`
-- `opusscript`
-- `prism-media`
-- **FFmpeg** (one of those)
-    - [`FFmpeg`](https://ffmpeg.org/) (installed and added to environment)
-    - `ffmpeg-static`
-
-### AudioManager Instance
-
-#### Options
-
-**Declaration:**
-
-```
-AudioManager(ffmpegMode: string, renewInMs, number, connectionData: VoiceConnectionDataModel, audioData: VoiceAudioDataModel): IDisposable, IAudioManager
+```bash
+node -e "console.log(require('node:crypto').getCiphers().includes('aes-256-gcm'))"
+npm install libsodium-wrappers
 ```
 
-- `ffmpegMode`: 'Native' or 'Standalone'
-    - Native: [`FFmpeg`](https://ffmpeg.org/) installed on your system
-    - Standalone: FFmpeg-static as NodeJs library
-- `renewInMs`: renewal time > default is 1,5h (5400000ms)
-- `connectionData`: Options for voice connection. (type of **VoiceConnectionDataModel**)
-- `audioData`: Options for audio player. (type of **VoiceAudioDataModel**)
+For bundled ffmpeg support, install `ffmpeg-static` and use `ffmpeg.mode: 'static'`:
 
-#### Example
+```bash
+npm install ffmpeg-static
+```
 
-```js
-let audioManager = new AudioManager(
-    'Native',
-    5400000,
-    {
-        VoiceChannelId: 0, //voice channel id where to play music
-        GuildId: 0, //guild id
-        VoiceAdapter: 0, //guild VoiceAdapter
+If ffmpeg is already available on the host PATH, use `ffmpeg.mode: 'native'`.
+
+### AudioManager Example
+
+```ts
+import { AudioManager } from 'discord-audio-stream';
+
+const manager = new AudioManager({
+    connection: {
+        guildId: guild.id,
+        channelId: voiceChannel.id,
+        adapterCreator: guild.voiceAdapterCreator,
     },
-    {
-        ResourceType: '', //resource type like link or file
-        Resource: '', //auto play link or file name
+    source: {
+        type: 'url',
+        url: 'https://example.com/live-stream.mp3',
     },
-);
+    ffmpeg: {
+        mode: 'native',
+    },
+    renewIntervalMs: 5_400_000,
+});
+
+await manager.start();
 ```

+| ------------------------ | ---------------------------------------------------------------------------------- |
+| `setConnection(options)` | Replaces the voice connection target.                                              |
+| `setSource(source)`      | Replaces the audio source.                                                         |

+| `dispose()`              | Idempotently releases timers, ffmpeg, streams, player state, and voice connection. |
+
+### State
+
+```ts
+manager.state; // 'idle' | 'connecting' | 'ready' | 'playing' | 'paused' | 'stopped' | 'disposed'
+manager.isPlaying;
+manager.isConnected;
+```
+
+## 🔊 Audio Options
+
+### Volume
+
+Inline volume has a runtime cost in `@discordjs/voice`, so it is disabled by default.
+
+```ts
+const manager = new AudioManager({
+    connection,
+    source,
+    volume: {
+        enabled: true,
+        initialPercent: 50,
+    },
+});
+
+await manager.start();
+manager.setVolume(25);
+```
+
+Calling `setVolume()` without `volume.enabled: true` throws `AudioManagerStateError`.
+
+### ffmpeg Modes
+
+- `mode: 'native'` uses the `ffmpeg` executable from the host environment.
+- `mode: 'static'` resolves the optional `ffmpeg-static` package.
+- `executablePath` overrides both modes and is useful for Docker images or custom ffmpeg builds.
+
+Default output is raw Discord-compatible PCM: `s16le`, `48000 Hz`, `2 channels`.
+
+You can override ffmpeg arguments through `ffmpeg.inputArgs` and `ffmpeg.outputArgs`. When you override them, you are
+responsible for keeping the output compatible with `StreamType.Raw`.
+
+### Renewal
+
+By default, the manager schedules a renewal after `5_400_000 ms` so long-running streams can reconnect periodically.
+Set `renewIntervalMs: false` to disable this behavior:
+
+```ts
+const manager = new AudioManager({
+    connection,
+    source,
+    renewIntervalMs: false,
+});
+```
+
+`stop()` and `dispose()` always clear the renewal timer.
+
+## 🧯 Errors
+
+The package exports these error classes:
+
+- `AudioManagerError`
+- `AudioManagerConfigError`
+- `AudioManagerStateError`
+- `FfmpegProcessError`
+
+Configuration problems, such as a missing source or invalid URL, throw `AudioManagerConfigError`. Invalid lifecycle
+operations, such as calling `pause()` while nothing is playing, throw `AudioManagerStateError`.
+
+## 📋 Migration From `0.7`
+
+Version `1.0` intentionally breaks the old PascalCase API.

+## 🧑‍💻 Development
+
+```bash
+npm ci
+npm run check
+npm run build
+```
+
+`npm run check` runs formatting, linting, type-aware linting, TypeScript type checking, and unit tests.
+
+Release version stamping is separate from normal builds:
+
+```bash
+npm run release:version
