How to remove vocals from a FLAC file
FLAC gives you lossless compression at about half the size of an equivalent WAV, which means you can fit more music under VocalSplit's 100 MB limit without sacrificing quality. It is the format of choice for audiophiles feeding our separator.
VocalSplit accepts FLAC directly — no need to convert to WAV first. The decoder runs on the server and the stems come back as lossless 24-bit WAV regardless of your source format.
Step-by-step
- Open VocalSplit.io. Works in any modern browser — Chrome, Safari, Firefox, Edge.
- Upload your FLAC file. Drop the file into the upload area. Files up to 100 MB are supported, which at FLAC compression is roughly 30+ minutes of CD-quality audio.
- Pay for the split. One split is $0.99, 10 splits for $4.99, or 50 for $14.99. Credits never expire.
- Wait around 25 seconds. FLAC processes a bit faster than uncompressed WAV because the file is smaller, but slower than MP3. Most FLAC tracks finish in under 25 seconds.
- Download WAV stems. Vocals and instrumental are returned as 24-bit WAV files — lossless all the way through, no quality lost at any stage.
Tips for better results
- FLAC files from Bandcamp or HDtracks are ideal sources — they preserve the full studio master quality.
- If you want FLAC output instead of WAV, convert the downloaded WAVs locally with ffmpeg or xACT.
- Multi-channel FLAC (5.1 surround) is not supported — convert to stereo first.
