4
+ - Model registry (metadata.json)
5
+ - Audio upload & reuse

+ Backend **TIDAK melakukan processing audio**.
9
+ Processing dilakukan oleh worker terpisah.

+ # Worker – RVC Processing Engine
2
+
3
+ Worker bertugas:
4
+ - Membaca job dari backend
5
+ - Menjalankan voice conversion menggunakan RVC
6
+ - Menyimpan output audio
7
+ - Update status job
8
+
9
+ Worker berjalan **terpisah dari backend**.
10
+
11
+ ---
12
+
13
+ ## Requirements
14
+ - Python **3.10 (RECOMMENDED)**
15
+ - FFmpeg (tersedia di PATH)
16
+ - (Optional) NVIDIA GPU + CUDA
17
+
18
+ ### Python 3.13 **tidak didukung** oleh sebagian library audio & ML.
19
+
20
+ ---
21
+
22
+ ## Install dependencies
23
+ ```bash
24
+ pip install -r requirements.txt
25
+ ```
26
+
27
+ Jika terjadi error terkait pip:
28
+ ```bash
29
+ python -m pip install "pip<24.1"
30
+ ```
31
+
32
+ ## Run worker
33
+ ```bash
34
+ python main.py
35
+ ```
36
+
37
+ Worker akan:
38
+ - mencari job dengan status queued pada `status.json`
39
+ - memproses audio
40
+ - menghasilkan `output.wav`
41
+ - mengubah status menjadi done pada `status.json`
