# install ffmpeg

```bash
apt-get install ffmpeg

# Convert .wav file to mp3

```bash
ffmpeg -i track01.wav -acodec mp3 track01.mp3
```

You can also specify the bitrate of the MP3 with the -ab flag. 

```bash
ffmpeg -i track01.wav -acodec mp3 -ab 64k track01.mp3
```

Convert a folder full of .wav into .mp3 

```bash
for i in *.wav; do ffmpeg -i "$i" -acodec mp3 -ab 64k "$(basename "$i" .wav)".mp3 ; done
```
