Karaoke Forums

EDIT:  Okay...I'll try to explain my problem again more coherently so that someone may actually be able to help me.

My husband just installed a new sound card on our computer last night, "Sound Blaster Live," and I tried recording today with CEP, which I've been using.  When I play back my recording, the tempo of my vocals is noticeably faster than the backing (especially more noticeable to me after about a minute into the song).   The vocal track is not recording at the tempo it should be for some reason and I don't know if there's a setting either on CEP or on Sound Blaster Live that needs to be changed to make them compatible.  I never had this problem until after this new sound card was installed.  Any thoughts on what's going on?

Geez....... never had that happen before. Maybe some of the Techie people can give ya some good suggestions.....

I have the SoundBlaster Live, never had it do anything like that... I love this soundcard.

(and WHY am I hanging out in the Tech forum today??)  :shock:  :(

Not the most interesting place to hang out...my eyes start glazing over with all this kind of stuff...and my hubby's a computer programmer.  I hope someone will have some answers...I don't know if there's a setting either on Sound blaster or CEP that is making the two programs incompatible.  No recording until I get it figured out.  The tempo of the vocal track is too fast for some reason.

Maybe, just maybe, you may be recording at a different bit rate as compare to the backing track. Check that first.

I dont like venturing guesses and I have no experience with CEP but here are some basic steps in setting up a computer for audio. Its a process of elimination.

Usually the computer is dedicated only to audio and everything not related is disabled
Assuming you have XP here is a link to explain this.
Here is another handytool

Install the latest updates/drivers for the SB Live here

Thanks for the links.  I did try checking the sample rate settings on both tracks and they're the same.

Juan...I just checked the bit rates, too, and they're the same between the backing and vocal track.

Hmmm that's weird.......Asumming your using XP, you could try this......


Go to your start menu, select control panel, select sound, speech and audio devices..
Go into audio menu, on the sound playback and sound recording tabs, make sure your new soundcard is selected as your default device.

Then go into the voice menu, and do the same thing for your voice playback, and voice recording options, not sure if it will work, but it couldn't hurt to try..

Oh yea, this is also assuming your plugging your mic directly into your sound card, if your using some kind of pre-amp, or other device, than that should be your default device for those options.

I checked out all the settings and they're all "Sound Blaster Live."  I also checked CEP to see what soundcard it listed as first in order of preference for both playback and recording and noticed the recording box still had "Wave Mapper."  I changed it and tried recording again, but still the vocal track is out of sync.  Tried going out of CEP and reimporting the backing and recording again...still problem not solved.

I also tried changing the music backing to 48000 instead of 44100, but it changes the pitch and tempo of the backing even though now the vocals are in sync.  Not a solution, but hopefully getting closer to the problem.

Does CEP have a clock option to change the rate? Is it clocking at the right rate?

I checked help under "clocks" and found the following.  Does this look like something that would solve my problem?

"If this box is checked, Cool Edit Pro looks at the exact true time that the record device started and compares that with the time the master playback device started. If different, the recorded block’s position is adjusted so the recording starts in perfect sync with the playback. This option only works with new record tracks, not with recording on top of existing waveforms, or punch-ins.


If you have this option enabled, and you do a loopback test (by connecting the audio Out to the audio In and recording some “ticks”) and each recording is still a fixed amount out of sync, then you can adjust for this by entering this amount (in milliseconds) in the Latency field of Options > Device Properties for the recording device being used. To compute milliseconds, look at the difference in samples, multiply by 1000 and then divide by the sample rate. For example, if the recording consistently appears 27 samples ahead of the playback, the latency would be 27 * 1000 / 44100 or 0.61 ms. (The reason for the milliseconds format and not samples is because at various sample rates this latency will be different in terms of samples, but will be the same in terms of milliseconds.)


On sound cards that support sample accurate devices (i.e., synchronized device starting, and all devices keyed off of the same clock) you don’t need to check this box. This option allows for some measure of near sample-accurate synchronization across different sound cards, or when using with a single sound card that doesn’t use the same clock for playback and recording (such as the Sound Blaster Live! card)."

I don't know if I'm allowed to put long quotes in here or not.

Nope..... back to plan B  I use Sonar isnt there some CEP users here?

 

Errr..... what would plan B consist of Ollie? I've been following this thread, curiosity is killing me, I want her problem figured out as badly as she does now.  :D




Yeah......

Oh, you mean "smart" CEP users, who "know what they're doing"?
Ummm..... No.

>going to have a look-see in mine though, now I'm even more curious<

You got CEP? How do you import the the music backing into a track? Can you change the import sample rate? She needs it at 48 to sync with the vocal...

Here's the answer I finally got from "Creative," the company that puts out Sound Blaster:

"I am sorry but none of our value based cards are going to give you the
results you are wanting with multi track recording. You are going to
have to upgrade to a card that has ASIO support before you can get rid
of the latency between the tracks.
Click on the link below to see more information on ASIO support and
which of our sound cards support ASIO."

I went to the link and looked up which cards support ASIO (whatever that means) and there are three Audigy cards and one FX card.  

Why can everyone else use Sound Blaster Live with CEP?  I'm wondering now if there isn't something to the "clock" fix.  What do you think?

Ummm..... not really sure.

I use Audiograbber, and grab the tracks to cdg + compressed file (usuallly, cause I practice in my comp as well) ... then just insert it like that into CEP. (from a folder)

Other times, if it's a song I don't feel I need to practice with the lyrics, I just right click on the track and do "insert wave".... and yank it off the cdg. (just the wav)

On rare occasion, it tells me "the sample rate blah, blah, blah..." message, I just click "okay" through it, but I think what it puts it at is ...... shyt, lemme go see.... I don't commit this stuff to memory you know. (I gotta save my brains' HD space for lyrics and rythm patterns and such)  LOL

Bologny..... that's a "sorry, we don't know how to answer your question" type of answer. I HAVE a Sound Blaster Live... and use CEP. I don't have this problem at all.

Okay, that may not even be what the heck your talking about, but when CEP converts a file for me to make it work in there, that's what it says it's converting it to.

I really, don't know NEAR as much about CEP and audio recording, and all that jazz as most people do. I haven't played with even a tenth of what that program has to offer, most likely much less than a tenth. (really)

But I'm gonna try to play with that "clock" thingee... which is, again, totally new to me... But I'll dig around in there.

Its not a latency problem Its a sample rate issue... In Sonar under audio settings there is an option to select the sample rate before importing the music backing or recording into another track. I would think if you have this option and imported with a 48 rate the tempo would be right  Maybe Im thinking wrong but thats what I feel...

As far as asio or drivers you want to use wdm rather than mme windows original....
