# Audio search system with Milvus
4+
5+
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.
6+
7+
## Local Deployment
8+
9+
### Requirements
10+
11+
- [Milvus 0.10.5](https://milvus.io/docs/v0.10.5/milvus_docker-cpu.md) (please note the Milvus version)
12+
- [MySQL](https://hub.docker.com/r/mysql/mysql-server)
13+
- [Python3](https://www.python.org/downloads/)
14+
15+
### Run Server
16+
17+
1. **Install python requirements**
18+
19+
```bash
20+
$ cd bootcamp/solutions/audio_search/webserver/
21+
$ pip install -r audio_requirements.txt
22+
```
23+
24+
2. **Modify configuration parameters**
25+
26+
Before running the script, please modify the parameters in **webserver/audio/common/config.py**:
27+
28+
| Parameter | Description | Default setting |
29+
| ------------ | ------------------------- | --------------- |
30+
| MILVUS_HOST | milvus service ip address | 127.0.0.1 |
31+
| MILVUS_PORT | milvus service port | 19530 |
32+
| MYSQL_HOST | mysql service ip | 127.0.0.1 |
33+
| MYSQL_PORT | mysql service port | 3306 |
34+
| MYSQL_USER | mysql user name | root |
35+
| MYSQL_PWD | mysql password | 123456 |
36+
| MYSQL_DB | mysql datebase name | mysql |
37+
| MILVUS_TABLE | default table name | milvus_audio |
38+
39+
3. **Star server**
40+
41+
```bash
42+
$ cd webserver
43+
$ python main.py
44+
```
45+
