Sure, I can help you with that. Here is a basic Python code snippet that can download a video's audio from YouTube (assuming the video is available for download and you have the YouTube Data API set up):

```python
import os
from googleapiclient.errors import HttpError
from google.oauth2.credentials import service_account

# replace with your own values
SCOPES = ['https://www.googleapis.com/auth/youtube.readonly', 'https://www.googleapis.com/auth/youtube.force-ssl']
SERVICE_ACCOUNT_FILE = 'your_service_account_file.json'
VIDEO_ID = 'your_video_id_here'

def download_audio(service, video_id, destination_path):
    try:
        response = service.media_files().list(
            part='id',
            body={
                'id': video_id,
                'fields': 'id,contentDetails.inputVideo.caption.articleTrackIds.trackId.src'
            },
            media_type='media'
        ).execute()

        caption_track = response.get('items', [])[0].get('contentDetails', {}).get('inputVideo', {}).get('caption', {}).get('articleTracks', [])[0]
        source_url = caption_track.get('src', '').replace('https', 'http')

        if not source_url.endswith('.mp4'):
            source_url += '.mp4'

        download_command = ['youtube-dl', '--quiet', '--skip-download', '--extract-audio', source_url, '-o', destination_path]
        os.system(' '.join(download_command))

        print("Audio download complete.")

    except HttpError as error:
        print("An error occurred: {}".format(error))

if __name__ == '__main__':
    # set up authentication
    credentials = service_account.Credentials.from_service_account_file(
        SERVICE_ACCOUNT_FILE,
        scopes=SCOPES)

    # construct the client object and get a youtube data object
    youtube = googleapiclient.discovery.build('youtube', 'v3', credentials=credentials)

    # replace with your own values
    video_id = 'your-video-id-here'
    destination_path = 'path/to/destination/file.mp4'

    download_audio(youtube, video_id, destination_path)
```

Note that this code is written using Google API client libraries, so you'll need to install them if you haven't already. You can do this using pip:

```bash
pip install google-auth google-auth-oauthlib google-auth-httplib2 google-auth-httplib2-mock google-apis-python-client googleapis.client.discovery
```

Also, you'll need a service account key for your YouTube channel, which can be obtained from the Google Cloud Console (if you haven't already):

1. Create a new second project in the Google Cloud Console.
2. Enable the YouTube API on this project.
3. Create a new service account, choose the "JSON" file format, and click "Create".
4. Download and save the JSON key file.

Sure, to download audio from a YouTube video, you can use a Python library called `pytube` along with `moviepy` to extract audio. Here's a simple script that does that:

```python
from pytube import YouTube
from moviepy.editor import AudioFileClip

# YouTube video URL
url = 'https://www.youtube.com/watch?v=dQw4w9WgXcQ'  # replace with your YouTube video URL

# Create a new YouTube object
yt = YouTube(url)

# Get the first video stream
video = yt.streams.first()

# Download the video
video.download('/path/to/download/directory')  # replace with your path

# Convert video to audio
AudioFileClip('video_file_name').audio.write_audiofile('audio_file_name.mp3')
```

Replace `'/path/to/download/directory'` with the path where you want to download the video and `'video_file_name'` and `'audio_file_name'` with the names you want for your video and audio files.

Please note that this code will download the video first and then convert it to audio which might take some time depending on the size of the video.

Also, you need to install the required libraries if you haven't done so. You can install them using pip:

```bash
pip install pytube moviepy
```

For `moviepy`, you might also need to install or update `ffmpeg` and `imageio` which are used by `moviepy` for video processing. You can install them as follows:

```bash
pip install imageio ffmpeg
```

If you are on Linux, you might need ffmpeg system package which can be installed as follows:

```bash
sudo apt-get install ffmpeg  # for Ubuntu, Debian, etc.
sudo yum install ffmpeg  # for CentOS, RHEL, etc.
```

On Windows, you can download a static build of ffmpeg from https://ffmpeg.zeranoe.com/builds/ and add it to your system PATH.

Please ensure you have the necessary permissions to download and convert videos from YouTube in accordance with their terms of service. This script is intended for personal use and educational purposes only.
