Detailed Description

template<class T>
class audio_tools::ICYStreamT< T >

Icecast/Shoutcast audio stream that separates ICY metadata from audio bytes.

ICY/Shoutcast servers interleave metadata blocks into the audio byte stream. This wrapper enables ICY metadata handling while exposing a clean audio-only stream via the standard read/available methods. Metadata is parsed by MetaDataICY and delivered through a user-supplied callback.

The class inherits from AbstractURLStream and delegates network/HTTP work to an underlying URL-like stream instance of type T. ICY support is enabled by adding the request header "Icy-MetaData: 1" and by removing metadata bytes from the returned audio stream while forwarding metadata via the callback.

Notes

If you run into performance issues, check if the server delivers data with HTTP chunked transfer encoding. In that case, using protocol "HTTP/1.0" can sometimes improve performance.
Audio bytes returned by read()/readBytes() contain no metadata; metadata is only available through the callback.
Use the following predefined usings:
- ICYStream = ICYStreamT<URLStream>;
- BufferedICYStream = ICYStreamT<BufferedURLStream>;
- ICYStreamESP32 = ICYStreamT<URLStreamESP32>;

Template Parameters

T	Underlying URL stream type; must implement the AbstractURLStream interface (e.g., provide begin/end/read/available/httpRequest, credentials, headers, etc.).
