Frequently Asked Questions
What is a beat blueprint? +
A beat blueprint is a comprehensive AI analysis of your beat including BPM, musical key, energy mapping, hook window detection, groove analysis, vocal space measurement, platform virality scores, and actionable tips — all in a downloadable PDF.
How do the viral loops work? +
After analysis, our AI identifies the highest-energy, most loopable sections and cuts 3 perfectly-looping clips: a short TikTok hook (~7s), a standard loop for Reels (~15s), and an extended version (~30s). Each is beat-aligned and crossfaded for seamless infinite repeat.
Is FlowSoHot really free? +
Yes! Full beat analysis, downloadable blueprint PDF, AI-powered answers, and 3 viral loop cuts — completely free. We ask for your email to send results and notify you about Pro features.
What file formats do you support? +
MP3 and WAV files up to 20MB. For best results, upload a clean instrumental beat rather than a full mixed song with vocals.
How accurate is the BPM detection? +
Very accurate — we use the same professional-grade audio analysis libraries used by major platforms. BPM detection is typically within ±1 BPM for beats with clear rhythm.
Can I use the viral loops on TikTok and Instagram? +
Absolutely. Loops export as MP3s you can upload directly to TikTok, Instagram Reels, YouTube Shorts, or any platform. They loop seamlessly, which is exactly what these platforms reward with algorithmic reach.
