Karaoke Tracks
What is Karaoke Tracks?
Karaoke Tracks at x-minus.pro is a community karaoke library where you search, stream, and download backing tracks across genres and languages. The catalog lists more than 700,000 tracks, with collections for love songs, movie soundtracks, holiday themes, and dozens of other categories. Each track opens in a web player with on-page pitch and tempo controls.
Where commercial karaoke apps license a fixed catalog, Karaoke Tracks relies on community uploads, so you get regional songs, fan-made arrangements, and obscure titles that rarely appear on Smule or Singa. Track quality and metadata vary by uploader, which is the trade-off for breadth across languages and themes.
Registered users can upload their own backing tracks, build playlists, and browse recent uploads or the TOP 50 chart. The site also hosts separate browser tools for AI vocal removal with stem splitting options and a transpose page for changing pitch or tempo on any uploaded audio file.
CassetteAi
What is CassetteAi?
CassetteAi is a real-time audio generation API for developers who need music, sound effects, or speech inside apps and games. Its models render a 30-second music sample in under 2 seconds and a full 3-minute track in under 10, at 44.1 kHz stereo. One SDK covers all three modalities through the same call shape.
Cloud audio APIs usually add round-trip latency that breaks interactive experiences. CassetteAi targets on-device inference with sub-50 millisecond time-to-first-audio and pay-per-second billing instead of monthly seats. The homepage cites 23 ms first-sample latency and deterministic seeds so game loops can re-roll SFX per frame without drift.
Music costs $0.02 per output minute and SFX costs $0.01 per generation, with no tier commitments. You call the models through fal.ai using JavaScript, Python, or cURL. Text-to-speech with zero-shot voice cloning is listed as launching soon.
Game studios, creator tools, and real-time media pipelines are the stated audience. Pixl Technologies runs the company from Salt Lake City, with engineering spread across North America and Europe.
