# TuneStem

> TuneStem is an independent browser-based AI vocal remover that separates authorized music into vocals and instrumental tracks. Users can upload MP3 or WAV audio, or start from a public Suno song URL, then preview and download the separated tracks.

TuneStem produces two outputs: vocals and instrumental. It does not provide separate drums, bass, guitar, or piano stems. Local uploads support MP3 and WAV files up to 100 MiB; FLAC must be decoded to WAV before uploading. Separation quality depends on the source mix, and vocals, harmonies, reverb, or other artifacts can remain.

Anonymous access depends on the available daily allowance returned by the service. Signed-in vocal separation currently requires 5 AI credits per task. Signed-in users can receive 5 daily credits on their first eligible visit of the business day, subject to server-side eligibility and deduplication. These are not promises of unlimited free processing.

Users must own or have permission to process the audio. Separation does not grant copyright, ownership, licensing, or commercial-use rights. TuneStem is not affiliated with or endorsed by Suno. Public guides are informational; account data, task pages, source files, and generated audio are not public reference material.
