+# Audio search system with Milvus
+
+This project uses [PANNs](https://github.com/qiuqiangkong/audioset_tagging_cnn)(Large-Scale Pretrained Audio Neural Networks) for Audio Pattern Recognition to perform audio tagging and sound event detection, finally obtaining audio embeddings. Then this project uses [Milvus](https://milvus.io/docs/v0.11.0/overview.md) to search for similar audio clips.
+
+## Local Deployment
+
+### Requirements
+
+- [Milvus 0.10.5](https://milvus.io/docs/v0.10.5/milvus_docker-cpu.md) (please note the Milvus version)
+- [MySQL](https://hub.docker.com/r/mysql/mysql-server)
+- [Python3](https://www.python.org/downloads/)
+
+### Run Server
+
+1. **Install python requirements**
+
+   ```bash
+   $ cd bootcamp/solutions/audio_search/webserver/
+   $ pip install -r audio_requirements.txt
+   ```
+
+2. **Modify configuration parameters**
+
+   Before running the script, please modify the parameters in **webserver/audio/common/config.py**:
+
+   | Parameter    | Description               | Default setting |
+   | ------------ | ------------------------- | --------------- |
+   | MILVUS_HOST  | milvus service ip address | 127.0.0.1       |
+   | MILVUS_PORT  | milvus service port       | 19530           |
+   | MYSQL_HOST   | mysql service ip     | 127.0.0.1       |
+   | MYSQL_PORT   | mysql service port   | 3306            |
+   | MYSQL_USER   | mysql user name      | root            |
+   | MYSQL_PWD    | mysql password       | 123456          |
+   | MYSQL_DB     | mysql datebase name  | mysql           |
+   | MILVUS_TABLE | default table name        | milvus_audio    |
+
+3. **Star server**
+
+   ```bash
+   $ cd webserver
+   $ python main.py
+   ```
+
