YouTube Audio Extractor - Audio Files & Transcripts

Turn YouTube and YouTube Music links into downloadable audio and timed transcripts.

How It Works

Looking for a YouTube audio downloader or a practical YouTube audio API alternative? Paste public YouTube or YouTube Music links and choose MP3, M4A, WebM, FLAC, WAV, Ogg Vorbis or ALAC. Every saved track includes a public download link, title, artist, duration, thumbnail, views, likes, publish date and optional timed transcript.

Use the dataset for podcast production, audio archives, research and AI training data. Export as JSON, CSV or Excel, or pull results through the Apify API. Pay $0.008 per track plus $0.0025 per saved MB; failed downloads are not charged.

Pricing

Event	Cost
Audio track	$0.008
Saved audio	$0.0025/MB
Transcript	$0.0015
Residential proxy	$0.02/MB

There is no included storage allowance: every saved megabyte is billed from the first one. A 5 MB track costs $0.0205 and a 50 MB track costs $0.133. Failed downloads are not charged for the track or saved MB, but metered proxy bandwidth that was already consumed is billed. Set maxProxyMb to 0 if you want to avoid residential proxy charges entirely.

FAQ

Which formats are supported?

MP3, M4A, WebM, FLAC, WAV, Ogg Vorbis and ALAC. M4A and WebM keep the native audio profile; other formats are converted.

Can I download only part of a track?

Yes. Set startTimeSeconds and endTimeSeconds to keep a section.

Where are the audio files?

Each row includes a public downloadUrl that does not require an Apify login. Files are also listed in the run's key-value store.
