# General Tools FAQ

> Quick answers about Vocuno's general tools — Create Song, Stems, Lyrics, the pipelines, and the Toolbox.

Quick answers about the tools in the **General Tools** section. For questions about the platform itself, plans, or distribution, see the [General FAQ](/faq/general).

<AccordionGroup>
  <Accordion title="What's the difference between the pipelines?">
    [Create Vocals](/create/create-vocals) generates a full song from scratch. [Add Vocals to Track](/create/add-vocals-to-track) lays AI vocals over your instrumental. [Add Instrumental](/create/add-instrumental) builds a backing track under your vocal. [Transform Vocals](/create/transform-vocals) re-sings a vocal in a different voice. [Voice Conversion](/create/voice-conversion-1) directly swaps the voice on existing vocals.
  </Accordion>

  <Accordion title="When should I use Voice Conversion vs Transform Vocals?">
    Voice Conversion is one-shot — fastest, keeps your original phrasing exactly. Transform Vocals re-generates the take from scratch using transcribed lyrics, which often sounds more natural for full performances.
  </Accordion>

  <Accordion title="Which stem-separation model should I pick?">
    Start with Vocuno's advanced splitter or LALAL.ai (the widest custom-stem support — drums, bass, guitar, etc.). Moises, BandLab, and LANDR are worth trying when a mix separates poorly. Suno's stem split is only available on tracks generated with Suno inside Vocuno.
  </Accordion>

  <Accordion title="Why are some models more expensive?">
    ElevenLabs, MiniMax, and Lyria 3 have higher provider costs and use more credits per generation. Suno and MusicGPT are the most credit-efficient. Full breakdown on the [Credit Costs](/credit-costs) page.
  </Accordion>

  <Accordion title="What audio formats are supported for uploads?">
    Most tools accept MP3, WAV, FLAC, AAC, OGG, M4A, Opus, and AIFF. Clean, dry recordings give the best results across stem separation, voice conversion, and de-reverb.
  </Accordion>

  <Accordion title="Do failed generations cost credits?">
    No — credits are auto-refunded when a generation fails on our side.
  </Accordion>

  <Accordion title="Where do my generated tracks go?">
    Everything lands in your library and stays available across the app — you can pull any track into the [Studio](/using-the-studio) or send it to [Distribution](/distribute/overview).
  </Accordion>

  <Accordion title="I deleted a track by accident. Can I recover it?">
    Yes! All your deleted tracks stay in the trash for 30 days after initial deletion. To access the trash you can go to your projects and click on trash.
