# Streaming Music

## Streaming Methods
|
|
|
|
Koel supports three streaming methods which can be configured via the `STREAMING_METHOD` setting in `.env` file:
|
|
|
|
* `php`: Use native PHP `readfile()`. This is the default method, and the slowest and most unstable one.
|
|
* `x-accel-redirect`: Use nginx's [X-Accel](https://www.nginx.com/resources/wiki/start/topics/examples/x-accel/) module, designed for serving larger contents directly to the end user. Refer to [`nginx.conf.example`](https://github.com/koel/koel/blob/master/nginx.conf.example) for a sample nginx configuration file.
|
|
* `x-sendfile`: Use Apache's [mod_xsendfile](https://tn123.org/mod_xsendfile/) module. You'll need to install and configure the module manually. A sample configuration is as following:
|
|
```apache
|
|
LoadModule xsendfile_module libexec/apache2/mod_xsendfile.so
|
|
|
|
# These configuration can be put in the VirtualHost directive as well
|
|
<IfModule mod_xsendfile.c>
|
|
XSendFile on
|
|
XSendFilePath /mnt/media
|
|
</IfModule>
|
|
```
|
|
Note that although its home page denotes "Apache2/Apache2.2," the module itself is known to work with later versions of Apache as well.
|
|
:::tip Tip
|
|
If you're using [Koel mobile app](https://koel.dev/#mobile) and can't play the songs, try switching the streaming method to `x-accel-redirect` or `x-sendfile` instead of `php`.

:::warning Notice
|
|
`STREAMING_METHOD` doesn't have effects if you're transcoding or streaming from a cloud storage.

## Transcoding FLAC
|
|
|
|
Koel supports transcoding FLAC to mp3 on the fly when streaming music. This behavior can be controlled via a `TRANSCODE_FLAC` setting in `.env` file:
|
|
|
|
* `false`: Disable FLAC transcoding. Koel will stream FLAC files as-is, producing the lossless audio quality. This is the default behavior.
|
|
* `true`: Enable FLAC transcoding. Koel will transcode FLAC to mp3 on the fly. You'll need to have [FFmpeg](https://ffmpeg.org/) installed on your server and set its executable path via the `FFMPEG_PATH` setting in the `.env` file. The transcoding quality can also be controlled via `OUTPUT_BIT_RATE` (defaults to `128`).
