  • Indie musician needing fast, affordable mastering
    Pick: LANDR Mastering

    LANDR provides AI mastering with reference matching, album mode, and stem control (Studio Pro) at $10/track or $19.99/month — far cheaper than a human engineer.

  • Content creator who wants to clone their voice for narration
    Pick: Voicebox

    Voicebox offers local voice cloning from just 3 seconds of audio, multi-voice storytelling, and unlimited TTS — all free, with full privacy.

  • Privacy advocate needing offline dictation/transcription

    LANDR Studio Pro now supports stem mastering (up to 4 stems), as announced in January 2024, giving more granular control than standard AI mastering.

    Pick: Voicebox

    Voicebox supports MCP (Model Context Protocol) for agent speech, making it a natural fit for AI assistant projects requiring local voice output.
