+# Play multiple format music from microSD card
+
+- [中文版](./README_CN.md)
+
+## Example Brief
+
+This example demonstrates playing music in MP3 formats from online HTTP stream via HTTP IO. The music files are then decoded using a decoder element, processed by audio effects, and finally output through the CODEC_DEV_TX IO.
+
+## Example Set Up
+
+### Default IDF Branch
+
+This example supports IDF release/v5.3 and later branches.
+
+### Configuration
+
+
+This example requires prior configuration of Wi-Fi connection settings. Please specify the `Wi-Fi SSID` and `Wi-Fi Password` by navigating to `menuconfig > Example Configuration`.
+
+
+### Build and Flash
+
+Before compiling this example, ensure that the ESP-IDF environment is properly configured. If it is already set up, you can proceed to the next configuration step. If not, run the following script in the root directory of ESP-IDF to set up the build environment. For detailed steps on configuring and using ESP-IDF, please refer to the [ESP-IDF Programming Guide](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/index.html)
+
+```
+./install.sh
+. ./export.sh
+```
+
+Here are the summarized steps for compilation:
+
+- Enter the location where the HTTP music playback test project is stored
+
+```
+cd $YOUR_GMF_PATH/gmf_examples/basic_examples/pipeline_play_http_music
+```
+
+- Select the target chip for compilation. For example, to use the ESP32S3:
+
+```
+idf.py set-target esp32s3
+```
+- Select the compilation board, taking esp32 s3 Korvo V2 as an example:
+
+```
+idf.py menuconfig
+In 'menuconfig', select 'GMF APP Configuration' -> 'Audio Board' -> 'ESP32-S3-Korvo V2', and then save and exit
+```
+
+- Build the Example
+
+```
+idf.py build
+```
+
+- Flash the program and run the monitor tool to view serial output (replace PORT with the port name):
+
+```
+idf.py -p PORT flash monitor
+```
+
+- Exit the debugging interface using ``Ctrl-]``
+
+## How to use the Example
+
+### Example Functionality
+
+- After the example starts running, it will automatically play the music files transmissed by the HTTP, stop and exit after playback is complete, with the following output:
