Multi-track Audio; latency, sync, or what?
on Dec 30, 2016 at 7:04:30 pm

OK, so i started out years ago with Vegas 4, but have taken over 10 years off due to health issues. Now i'm on Vegas Pro 10...

I don't remember ever having the following issues on my old Win XP system: I use this solely for audio (NO video)...by the time i get to my second audio track (Playback & record) it's already off by a split second. I tried nudging it to line up, but then it's like the rest of the song is now slightly out of sync. I searched all over the internet, and only find the threads about "Audio out of sync with video"...but nothing about multi tracking out of sync. I checked my Performance (ie. CPU & Phys Mem usage) while running vegas...seems extremely low. So, i'm assuming it's my settings???? Any hints, tips, tricks would be greatly appreciated.

System Specs:
Win7 Ultimate (64 bit)
AMD FX8120 (8 core) 3.1 GHz
(2x) EVGA 2GB GTX550ti's (SLI)
16GB DDR3 G.Skill Ripjaws
Corsair 120 SSD
Seagate 750 HDD
Seagate 1.5TB HDD
(WEI Score = 7.3)

This might help. Seems like a known issue.

Paul, thank you very much for the assist. Unfortunately, i just read that post & it doesn't give an answer...just says i may have to do what i've already been doing..."nudging." It's so odd that i never had this issue with previous versions of Vegas Pro, let alone a much older PC. And while i am embarrassed to admit this, i am recording acoustic guitar through the mic on my Microsoft HD PRO Webcam at the moment (USB). At least they are for scratch tracks...and sounds "so-so" for my current needs. I don't really have a lot of driver options (ie. ASIO), unless i run DI through my line-in on the sound card (Me thinks). Thanks again for your (And anyone's) input.

Although i dont have this issue, its a tricky one for some users.
You tried adjusting latency settings in the audio driver settings?

[Mike Otto] " I don't really have a lot of driver options (ie. ASIO), unless i run DI through my line-in on the sound card (Me thinks). "
You need ASIO drivers if you want to do multi-track recording in Vegas Pro without latency. It's that simple. Buy yourself an audio device with ASIO drivers and you should be fine. I'd recommend the PreSonus AudioBox USB. It's an awesome little box for audio.

I would stay away from anything M-Audio. While I've recommended M-Audio for years and they do make great hardware, their driver support (or rather lack of it) has left me cold. M-Audio has a nasty habit of abandoning their hardware leaving customers with little more than a "door stop". I have a perfectly good M-Audio Firewire 410 that doesn't have Windows 10 or macOS drivers so it is now completely useless. I have a friend that has an M-Audio Firewire 610 in the same position. DO NOT buy from M-Audio unless you want to throw out a perfectly good device because they stop making drivers for it! By comparison I have a PreSonus FireStudio Project that I bought around the same time as the M-Audio Firewire 410 and PreSonus still make drivers for it. So I can't in good conscious recommend M-Audio anymore.

Once you have an audio device with ASIO drivers, the latency problem will be gone.

John is right. That story is pretty much why I stopped buying good sound blaster cards about 5 years ago. There was really no other reason to stop supporting the Audigy 2 card that supported relevant formats, other than to obsolete hardware and sell more hardware upgrades to end users. The lack of good driver support lead to playback and stability issues in vegas. Once I removed the audio interface and used the more contemporary onboard audio interface stability improved in Vegas. Of course the signal to noise is a lot less, but few have really quiet / dampened listening environments.

Your latency is likely due to the poor audio implementation on the webcam to USB. Ironically, some programmer probably spent time aligning the audio to the video on the webcam by adding delay to the audio.

John, your advice is, as usual, excellent. It seems Cow has become my go-to Vegas problem solving resource.

Thanks Barry! That's one of the great things about the Creative COW community... People share the road they have travelled and tell you where all the potholes are. :-D

John, I wholeheartedly agree! Thank you very much (As well as the rest of you) for your helpful replies. When i read what you mentioned about the whole audio/video aspect of the USB CAM...it made a lot of sense. Much appreciated everyone.

Just a thought...

ASIO4ALL is a universal audio driver that has worked for me on sound devices that don't come with ASIO drivers in the past and it supports Win10.
