Achanak shuruaat ya ant galat kyun lagta hai
Aisa audio jo bina kisi ramp ke turant full volume par shuru ya khatam hota hai, wahi tarah ka sunayi dene wala discontinuity banata hai jiski charcha cuts aur clicks ke saath hui thi — khamoshi se full amplitude (ya ulta) ka achanak jump ek halka pop paida kar sakta hai, ya kam se kam, ek achanakpan jo technically click na hone par bhi unpolished lagta hai. Fades ise shuruaat mein zero se dheere-dheere volume badhaakar, aur ant mein wapas zero par laakar solve karte hain, taaki kahin bhi koi turant jump na ho.
Fade curve ka shape asal mein maayne rakhta hai, sirf duration nahi
Ek linear fade (ek constant rate par badalta volume) sabse aasan option hai, lekin yeh hamesha yeh nahi darshaata ki loudness asal mein kaise feel hoti hai — human hearing loudness ko lagbhag logarithmically perceive karti hai, isliye ek exponential ya S-curve fade seedhe linear ramp se zyada smooth aur natural lag sakta hai, khaastaur par lambe fades ke liye. Kisi cut point par click se bachne ke liye istemaal kiye gaye chote, quick fade ke liye, curve ka shape lagbhag maayne nahi rakhta, lekin kisi track ke ant mein ek jaan-boojhkar, kai-second ke fade-out ke liye, curve ka shape ek real creative choice hai jiske liye kuch options try karna uchit hai.
Fade kitna lamba hona chahiye yeh poori tarah context par depend karta hai
Sirf edit point par click khatam karne ke liye istemaal kiya gaya fade sirf kuch milliseconds ka hona chahiye — itna lamba ki discontinuity se bach sake, itna chota ki jaan-boojhkar kiye gaye fade jaisa feel na ho. Kisi gaane ke ant mein ek musical fade-out ek poori tarah alag, jaan-boojhkar kiya gaya creative element hai jo aam taur par kai seconds, kabhi-kabhi usse kahin zyada chalta hai, aur iska maqsad chhupaye jaane ki jagah piece ke hisse ke taur par suna aur feel kiya jaana hai.
Fades kisi bhi edited audio ke liye sasta insurance hain
Lagbhag kisi bhi trim ya cut kiye gaye audio clip mein — yahan tak ki jinhe iski zaroorat na lage — ek bahut chota fade-in aur fade-out jodna, briefly kiye jaane par perceptually kuch kharch nahi karta, aur yeh boundaries par possible click ya pop problems ki poori category ko khatam kar deta hai. Yahi wajah hai ki professional audio editing tools aksar kisi bhi cut ya trim par apne aap ek chota default fade laga dete hain, ise ek optional polish step ki jagah ek safety measure maante hue.
