Agar recorded exam class ki awaaz aur video ek hi amount se aage-peeche hain, pehle chhoti local recording mein gap naap kar OBS ke Advanced Audio Properties mein us audio source ka Sync Offset badlein. Agar video ko delay karna hai, to us video source par Render Delay filter test karein. Lekin agar mismatch waqt ke saath badhta ja raha hai, to ek fixed offset lagana kaafi nahi hoga: pehle recording ya stream ko monitor playback se compare karke drift ka pata karein.
Pehle pata karein: constant delay hai ya drift?
Recorded lesson stream karte waqt ek saaf event chun kar audio aur picture compare karein—jaise bolte hue chehre ka mouth movement, clap, ya slide change ke saath boli gayi line. Dekhein ki mismatch poori recording mein lagbhag ek jaisa rehta hai ya dheere-dheere badhta hai. OBS community forum bhi in dono ko alag symptoms maanta hai: ek constant offset ko naap kar adjust kiya ja sakta hai, jabki waqt ke saath badhta mismatch alag diagnosis maangta hai. OBS Project Community Forums
- Gap lagbhag constant hai: pehle relevant audio source ka Sync Offset naap kar adjust karein; zarurat par video ko Render Delay se delay karne ka test karein.
- Gap badhta ja raha hai: output recording/stream ko monitored audio se compare karein aur monitoring path, clocks, aur performance ki jaanch karein. Ek hi fixed offset drift ko theek nahi karega.
- Problem sirf headphones ya OBS monitoring mein sunai deti hai: recording ya stream ko alag se check karein. Monitor playback ko final output ka pakka saboot na maanein.
Exam class se pehle test recording banayein
OBS ke preview ya live monitor sunne bhar se sync confirm nahi hota. Chhoti local recording banayein aur us file mein wahi clear event dekhein. Jab mumkin ho, class se pehle private ya unlisted test stream karke uski playback bhi check karein. OBS apni Quick Start Guide mein pehli stream ya recording se pehle kuch minute test karne ki salah deta hai. OBS Quick Start Guide
- Sahi source dekhein: OBS ke Audio Mixer mein intended microphone, desktop audio, media source ya interface ka meter bolne/playing par move hona chahiye. Agar meter nahi hilta ya galat input capture hota hai, audio Sync Offset badalne se pehle device selection theek karein. OBS Quick Start Guide device ko manually select karne ki salah deta hai jab capture sahi na ho.
- Chhota sample record karein: lesson ka aisa hissa chalayein jisme bolna aur koi saaf visual cue ho. Playback mein cue aur sound ka relative gap dekhein.
- Output ko alag se verify karein: recording file dekhein; test stream ki playback bhi check karein, agar test stream ki ho. Isse pata chalega ki issue actual output mein hai ya sirf monitoring mein.
Constant audio delay ko Sync Offset se theek karein
Jab recording mein audio ka gap stable ho, tab usi audio source ko adjust karein jo late ya early hai. OBS mixer ke Advanced Audio Properties mein us source ka Sync Offset millisecond mein set hota hai. Positive value audio ko delay karti hai; negative value use pehle laati hai. Ye sign convention streaming-platform help article mein diya gaya hai: Kick Help: Audio issues on your Kick stream.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- Audio Mixer mein gear/menu khol kar Advanced Audio Properties chunein.
- Jis source ki timing galat hai, usi row mein Sync Offset badlein. Agar awaaz picture se pehle aa rahi hai, audio ko delay karne wali positive value test karein. Agar awaaz picture ke baad aa rahi hai, negative value test karein.
- Koi universal millisecond value copy na karein. Sahi amount aapke computer aur audio/video processing par depend karta hai; Focusrite bhi apni OBS setup guidance mein ise experiment se nikalne ko kehta hai. Focusrite Support: How to set up a Focusrite interface in OBS
- Nayi chhoti recording banayein aur wahi event dobara compare karein. Zarurat ho to value ko chhote increments mein refine karein, aur har change ke baad output recording ya stream playback verify karein.
Agar picture ko delay karna ho to Render Delay test karein
Kabhi-kabhi audio ko aage-peeche karne ke bajay video source ko delay karna zyada munasib hota hai—khaaskar jab aapka audio sahi ho aur picture pehle aa rahi ho. OBS ka Render Delay filter kisi source ki rendering delay karta hai aur OBS ise audio/video sync mein madad ke liye document karta hai. OBS Filters Guide
- Source list mein relevant video source—jaise recorded lesson ka media source ya capture source—par filter kholein.
- Us source par Render Delay filter add karke ek measured test value se shuru karein.
- Ek waqt mein sirf ek source ya timing control badlein. Chhoti recording dobara banayein aur wahi visual cue/sound compare karein.
Audio Sync Offset us audio source ki timing badalta hai; Render Delay us video source ki rendering ko delay karta hai. Faisla recording ya stream ke measured output se karein, sirf monitoring se nahi.

Agar mismatch waqt ke saath badhe to kya jaanchein
Monitoring aur output ko alag compare karein
Agar headphones mein sunne par gap badhta dikhe, lekin recording ya stream mein nahi, to mumkin hai masla monitoring path mein ho. OBS forum support mein ek sambhavit wajah batayi gayi hai: monitoring device aur OBS alag clocks follow kar sakte hain, jisse monitor buffering waqt ke saath badh sakti hai. Yeh har setup ka pakka sabab nahi hai; pehle output recording aur monitored audio ka farq establish karein. OBS Project Community Forums
OBS performance ko symptom hone par dekhein
Agar OBS render ya encode karne mein struggle kar raha ho, tab output frame rate/resolution, scene complexity, filters aur system resource load check karein. OBS in cheezon ko performance par asar daalne wale factors ke roop mein list karta hai; ye har audio-sync problem ka universal fix nahi hain. OBS Encoding Performance Troubleshooting
