Audio Extractor

Extract pure audio from videos and download audio content. Supports format conversion, metadata embedding, and batch playlist processing.

Prerequisites

Executor: Must use the remotion executor (provides yt-dlp, ffmpeg, deno)
JS Runtime: deno is required for YouTube extraction (yt-dlp 2025+ default). The remotion executor includes deno.
ffmpeg: Required for audio format conversion and metadata embedding. Included in remotion executor.

Limitations

Issue	Detail
YouTube rate limiting	Server IPs are frequently rate-limited by YouTube. If you get "This content isn't available, try again later", wait ~1 hour or ask the user to upload the audio file directly.
YouTube JS runtime	yt-dlp requires deno for YouTube. Without it: `No supported JavaScript runtime could be found`.
Geo-restrictions	Some content may be region-locked. Use `--geo-bypass` flag.
Authentication	Some platforms require cookies. Use `--cookies-from-browser` or `--cookies cookies.txt`.

Fallback strategy: If YouTube download fails, suggest the user upload the audio file directly or provide a direct audio URL.

Quick Start

# Extract audio (best quality, original format)
yt-dlp -x "URL"

# Extract as MP3
yt-dlp -x --audio-format mp3 "URL"

# MP3 with metadata and cover art
yt-dlp -x --audio-format mp3 --embed-metadata --embed-thumbnail "URL"

Audio Formats

Format Selection

Format	Command	Use Case
MP3	`--audio-format mp3`	Universal compatibility
M4A/AAC	`--audio-format m4a`	Apple devices, good quality/size
FLAC	`--audio-format flac`	Lossless, archival
WAV	`--audio-format wav`	Uncompressed, editing
OPUS	`--audio-format opus`	Best quality/size ratio
Vorbis	`--audio-format vorbis`	Open source, OGG container
Best	`--audio-format best`	Keep original (no conversion)

Quality Control

# VBR quality (0=best, 10=worst)
yt-dlp -x --audio-format mp3 --audio-quality 0 "URL"

# Specific bitrate
yt-dlp -x --audio-format mp3 --audio-quality 320K "URL"
yt-dlp -x --audio-format mp3 --audio-quality 192K "URL"

# FLAC (lossless - quality setting ignored)
yt-dlp -x --audio-format flac "URL"

Metadata Embedding

Embed All Metadata

# Metadata + thumbnail as cover art
yt-dlp -x --audio-format mp3 \
       --embed-metadata \
       --embed-thumbnail \
       "URL"

What Gets Embedded

Title
Artist/Uploader
Album (playlist name if applicable)
Track number (playlist index)
Upload date
Description
Thumbnail as cover art

Custom Metadata

# Override artist
yt-dlp -x --audio-format mp3 \
       --embed-metadata \
       --parse-metadata "uploader:%(artist)s" \
       "URL"

# Set album name
yt-dlp -x --audio-format mp3 \
       --embed-metadata \
       --parse-metadata "playlist:%(album)s" \
       "URL"

Playlist/Batch Processing

Download Full Playlist as Audio

# Basic playlist extraction
yt-dlp -x --audio-format mp3 "PLAYLIST_URL"

# With numbering and organization
yt-dlp -x --audio-format mp3 \
       --embed-metadata --embed-thumbnail \
       -o "%(playlist)s/%(playlist_index)02d - %(title)s.%(ext)s" \
       "PLAYLIST_URL"

# Skip already downloaded
yt-dlp -x --audio-format mp3 \
       --download-archive downloaded.txt \
       "PLAYLIST_URL"

Selective Download

# First 10 tracks
yt-dlp -x --audio-format mp3 -I 1:10 "PLAYLIST_URL"

# Specific tracks
yt-dlp -x --audio-format mp3 -I 1,5,10 "PLAYLIST_URL"

# Last 5 tracks
yt-dlp -x --audio-format mp3 -I -5: "PLAYLIST_URL"

Extract audio from local video file:

ffmpeg -i video.mp4 -vn -acodec libmp3lame -q:a 0 audio.mp3

Troubleshooting

Issue	Solution
"ffmpeg not found"	Install ffmpeg: `brew install ffmpeg` / `apt install ffmpeg`
No cover art	Add `--embed-thumbnail` (requires ffmpeg)
Wrong metadata	Use `--parse-metadata` to remap fields
Poor quality	Use `--audio-quality 0` or lossless format
