How to encode WAV file to MP3 file.
4+
5+
### Command Line
6+
7+
```powershell
8+
enc_mp3_file --input <wav file> --output <mp3 file>
9+
```
10+
11+
### Examples
12+
13+
List options:
14+
15+
```powershell
16+
./bin/x64/enc_mp3_file --help
17+
Usage: enc_mp3_file --input <wav file> --output <mp3 file>
18+
-h, --help
19+
-i, --input input WAV file
20+
-o, --output output MP3 file
21+
```
22+
23+
Encode the input file `./assets/aud/equinox-48KHz.wav` into output file `./output/enc_mp3_file/equinox-48KHz.mp3`:
24+
25+
```powershell
26+
mkdir -Force -Path ./output/enc_mp3_file
27+
28+
./bin/x64/enc_mp3_file `
29+
--input ./assets/aud/equinox-48KHz.wav `
30+
--output ./output/enc_mp3_file/equinox-48KHz.mp3
31+
```
