Audio Extractor
Drop in a video and Spark Tray lifts the audio out for you — or paste a link and it pulls the sound straight from the web. Copy the original track losslessly in an instant, or convert to MP3, M4A, WAV, FLAC or Opus at the bitrate you pick.
Extracted audio saves to your Audio folder.

What it does
Everything Audio Extractor handles
A focused set of jobs, each done well — and nothing that phones home.
Extract original, instantly
Copy the existing audio track out untouched — no re-encode, no quality loss, and it finishes almost as fast as a file copy.
Convert to any format
Prefer a specific format? Re-encode to MP3, M4A, WAV, FLAC or Opus, and dial in the bitrate from 128 up to 320 kbps.
From a file or a link
Drop in files you already have, or paste a video URL and Spark Tray probes it — thumbnail, title and duration — before pulling the sound.
Whole batches at once
Hand it several files and each becomes its own job, so you can convert a folder of clips in a single pass.
Playlists, one job each
Point it at a playlist link and every video turns into its own extraction job you can follow or cancel individually.
Runs on your machine
ffmpeg does the work locally — nothing uploads, no account, and the audio never leaves your PC.

Under the hood
The engines, named plainly
The Audio Extractor leans on the same trusted tools as the downloader — here's the stack.
- Media processing
- ffmpeg (stream copy or re-encode)
- URL fetching
- yt-dlp (for From URL and playlists)
- Formats
- MP3, M4A, WAV, FLAC, Opus
- Bitrates
- 320, 256, 192 or 128 kbps (lossy formats)
- Modes
- Extract original (lossless copy) or convert
- Output folder
- Audio
- Platform
- Windows 10/11 (x64) — runs fully on your machine
“Extract original” stream-copies the audio with ffmpeg, so it's instant and bit-for-bit lossless; converting re-encodes to the format you choose. Pulling audio from a link uses yt-dlp, the same fetch engine as the Video Downloader. Only extract audio you have the rights to.
