NEED HELP WITH MIC DELAY

Posted: Mon Apr 14, 2008 3:43 pm

I use Sony acid, and every time I record vocals I know my timing is on point, but when I hear the playback the vocals are either delayed or ahead of the beat. I've tried every thing but nothing has worked. Do you guys know what the problem is?

First of all, one post is enough. Look on the right hand side where it says current topics.

Secondly, it would greatly help if you posted your system specs, otherwise any advice you get will be blind speculation.

The possiblity is that it's a latency issue but it is entirely possible that you are in fact off time. That's not unusual. Being exactly on time is not a natural thing. It helps to have some sort of click track going when you record.

Latency issue?

I don't know it's a stab in the dark without more info. I personally think it's user error but it's so hard to say without knowing more.

-Serious stab in the dark.

Are you recording to the same drive containing the OS?

Tried raising or lowering the buffers?

Are the vox accurate across the timeline, but just might need to be selected and moved a few ms forward or back to match up - quick and easy fix there, until you find the root of the problem that is...

3 feet = 1ms of delay i believe

This is slowing me down, after every track I record, I find myself going back and fixing the vocals to match the track. I say the time I spent trying to fix it is about I'll say 30 mins in total. Its very tiring when you have 30 separate takes that you have to fix. The computer is at my friend's house I have more info tomorrow.

I second that.

Google "Audio Recording Latency". That's more than likely your problem, especially if the vocals are the only live intrument track you are recording.

1 foot = ~ .88ms delay based on close proximity to sea level and 76 degrees farenheit.

Though this doesn't sound like it's the problem - it's a system latency, not a sound propogation latency.

Erm...I thought it was 1m = 1ms as well. I agree it ain't the problem but still.
And btw, 76F here is like WOOOFT. (24C I believe?)

Can you group the tracks, and move them all at once? If it's a fixed time offset, that is.

Really? Are we quibbling over +/- .22 ms?

No, 2'3".
Cucco said that "1 foot =~ .88 ms" which I'm guessing now is probably a typo.

Nope - no typo.

Speed travels at approximately 1130 feet per second (given the air temp of about 76 degrees farenheit at less than 100 ft above sea level and a humidity of about 50%). Divide 1130 feet into 1 and you wind up with 8.8 x 10 (-4th power) which is the same as .00088 or 8.8 ms per 1 foot.

I was just guessing and making a late night joke at this person who skipped reading his manuals

OK now there IS a typo.

I'll assume it's .88 ms per 1 foot as said earlier, and not 8.8 as you just said (although 0.00088 is .88ms).
