Frequently Asked Questions
Silence detection kitni accurate hai?
RMS windowing method use hoti hai — har 50ms window mein energy calculate hoti hai. Threshold -40 dB most recordings ke liye perfect hai. Studio recordings ke liye -50 dB, noisy field recordings ke liye -30 dB try karo. Settings tab mein real-time adjust kar sakte ho.
Export ke baad quality loss hogi?
Bilkul nahi — WAV lossless format mein export hota hai. Audio buffer directly encode hota hai, koi re-compression nahi. Content regions precisely joined hote hain — no crossfades, no artifacts.
"Remove All Silences" aur "Export Selected" mein kya fark?
"Remove All Silences" sare content regions ko join karta hai — ek complete cleaned file. "Export Selected" selected regions ko alag alag WAV files mein download karta hai — useful jab aapko specific parts chahiye.
Kya file private rehti hai?
100% private. Web Audio API browser mein process karta hai. Koi file kabhi server par nahi jaati — isliye large podcasts bhi safely analyze ho sakte hain.
Podcast editing ke liye best settings kya hain?
Threshold: -40 dB. Min Duration: 0.5s (natural pauses rakho). Merge Gap: 200ms (closely spaced silences ek mein merge honge). Re-Analyze hit karo — adjust karo jab tak results perfect na lagein.
