Why extract audio from YouTube?
YouTube hosts the world's largest library of audio content — podcasts, music, lectures, interviews, conference talks, and audiobooks. But YouTube doesn't offer a way to download audio files on desktop. You're forced to stream with the video running, draining battery and requiring an internet connection.
Common reasons to extract YouTube audio on Mac:
- Podcasts — many podcasters publish to YouTube first. Save episodes as MP3 for offline listening
- Music — save live performances, DJ sets, and unreleased tracks for offline playback
- Lectures — university lectures and conference talks are easier to review as audio
- Interviews — save long-form conversations to listen during commutes
- Language learning — extract audio from language lessons for repeated listening
How to Convert YouTube to MP3 on Mac — Step by Step
Download Star Video Downloader
Get the free app from starvideoapp.com. Unzip and move to Applications. Works on macOS 14+ with Apple Silicon and Intel Macs.
Copy the YouTube video URL
Open YouTube in your browser, find the video you want to extract audio from, and copy the URL from the address bar. Works with regular videos, Shorts, and playlist URLs.
Download the video
Paste the URL into Star Video Downloader and click Download. Choose the highest quality available — higher video quality means better audio source for conversion.
Open the Convert tab
Switch to the Convert tab in Star Video Downloader. Drag in the downloaded video file, or use the file picker to select it.
Choose audio format and convert
Select your target format — MP3, FLAC, WAV, AAC, OGG, or OPUS — and click Convert. The audio is extracted locally on your Mac and saved as a standalone file.
Tip: For the best audio quality, choose FLAC (lossless, smaller files) or WAV (lossless, uncompressed). For universal compatibility and small file sizes, MP3 at 320kbps is the standard choice.
Supported Audio Formats
Star Video Downloader's converter supports all major audio formats:
MP3
Universal format. Plays everywhere. Good quality at 320kbps with small file sizes.
AAC
Apple's preferred format. Better quality than MP3 at the same bitrate. Ideal for Apple devices.
FLAC
Lossless compression. Full quality, smaller than WAV. Best balance of quality and size.
WAV
Uncompressed audio. Maximum quality. Best for editing and professional use.
OGG
Open-source format. Excellent quality at low bitrates. Popular in gaming and open-source software.
OPUS
Modern, efficient codec. Outstanding quality at very low bitrates. Great for voice recordings.
YouTube to WAV on Mac
If you need the cleanest possible output for editing, archiving, or importing into audio software, WAV is the best YouTube audio format to choose on Mac. It stores uncompressed PCM audio, which makes it ideal for Logic Pro, Final Cut workflows, transcription tools, or any setup where you do not want extra compression.
FLAC gives you the same lossless quality in a smaller file, while MP3 is still the most convenient format for phones, cars, and general playback. If you want to fine-tune formats after downloading, the built-in video converter for Mac lets you switch between MP3, WAV, FLAC, AAC, OGG, and OPUS locally.

Why Not Use Online YouTube-to-MP3 Converters?
Online YouTube-to-MP3 websites may seem convenient, but they come with serious drawbacks:
- Aggressive ads and pop-ups — deceptive download buttons, auto-playing ads, and malware-laden redirects
- Malware risk — many sites bundle browser extensions, adware, or worse
- File size and length limits — can't convert videos longer than 10-20 minutes on most services
- Quality loss — server-side re-encoding at low bitrates produces noticeably worse audio
- Privacy concerns — your URLs and browsing habits are logged on someone else's server
- No lossless formats — online tools never offer FLAC or WAV output
Star Video Downloader handles everything locally on your Mac. No uploads, no tracking, no ads, and no restrictions. You can convert to lossless formats that online tools don't support.
