I record audio commentary with Audacity and gameplay with OBS.
OBS records 2 audio tracks : the game audio and my microphone, so that I can sync up the microphone recording from Audacity by simply overlaying that track in Sony Vegas Pro when editing the video.
I count down and do a tap to sync up the audio perfectly at the start of the video. However after mere minutes the audio track that was recorded with Audacity will start drifting out of sync, with a recording of 20-30 minutes it can get as much as a full second or more out of sync.. The audacity track will start getting ahead of the OBS recording. It either starts going faster, or the OBS recording goes slower.
Audacity is set up to record at 48khz with 32 bit-float quality. It is suggested to leave it at 32 bit for editing purposes and then export it into a .wav 16 bit file.
OBS records the video on CBR at 30fps and the audio on 48khz with a 160 bit rate (this audio gets muffled anyway, so the quality here is not important). I'm not sure if OBS records in 16 or 32 bit, I can only assume it's 16.
Sony Vegas Pro is set up to use 30 fps and 48khz.
I am not sure what I am doing wrong or what could be a possible cause of the 2 audio tracks drifting from perfect sync to out of sync. As it stands currently I am spending forever splitting my audio track and moving it around manually to keep it synced up with the recorded game audio&video from OBS.
Please help :)
