GMC Forum _ Recording _ Delay Problems (with Reaper)

Posted by: Rob_g Aug 6 2007, 10:54 PM

Ok so i've made this cool sounding backing track with guitar keyboard and bass, and had no delay problems. When I tried adding a second guitar that track would be delayed. But this only happens sometimes. Sometimes the timing will be perfect and others will suck. Anybody got a solution to my problem?

I know Andrew has mentioned you have to download something for it not to delay but I forget what it was. Im using my pod xt live for recording the guitars and my peavey pv14 mixer to record the keyboard and bass. could this be the problem? im open to suggestions.

You may need ASIO drivers for low latency. In your soundcard. If that's what you need.

blindwillie posted a link just rescently.

Yes, I mentioned ASIO4ALL which supports lots of soundcards that doesn't have an ASIO driver (or have a very poor one). But if you have a POD you shouldn't need ASIO4ALL, the POD ASIO driver should do the job. Make sure you are using POD's ASIO and not the regular Windows driver.

If you still get the delays it could be your computer that's overloaded, or your soundcard. I guess adding more tracks or effects would add up on the CPU load. Same with the soundcard. I've set all the Window settings to POD XT (input, output, MIDI) so when my POD is on all windows sound is routed (or mapped) through my POD and not the soundcard. So I can't say for sure what load an extra track adds to the souncard. I do know that adding several effects in a DAW-application really puts pressure on your computer and the different effects can be more or less well written and optimized and because of that I'm guessing more tracks would do the same.

A sidenote about the quality of ASIO drivers:
On two different computers I get lower latency in both a guitar amp simulator and a DAW with ASIO4ALL than with Creative ASIO.

woah man. I dont know how to do all that. Im really computer literate so this might be a little hard. All I know what to do really is change the recording device to my pod and change the playback through my computer. Can you make it easier for me to understand?

Sorry about this I kinda feal like a noob

You had no problems to record first guitar track right?
Than you probably pressed monitoring button on second guitar track channel which gave you delay(latency in this situation).
Look around and try to turn it off...
Tel me if is it working ok?

Let us know if Muris is on the right track (hihi). He knows way more about recording (and Reaper) than I do, I just starded to explore this. If that didn't help, post again in this thread and I will get some screenshots of my set up and post them here, that will make it easier to understand what I was trying to say, I'm no good at explaining stuff in an easy way smile.gif.

Actually,I used Reaper once or twice,not more wink.gif
That's just something I think it MIGHT be the problem rolleyes.gif

Reaper gives you a numerical readout of its i/o measured latency - top right hand corner. Assuming you are using the Pod's usb lead to the pc then I'd have thought that you would automatically having started the Pod's ASIO? (Sorry I don't have a Pod so I'm not sure.) If you are then I wouldn't think that you'd need ASIO4ALL as that is really for people who have sound cards that don't have ASIO at all.


IF you are using the Pod's ASIO driver then you might have to adjust the settings to reduce latency (Options-Preferences-Audio-Device and drop down box for ASIO (or POD ASIO) in Reaper). You need to lower the latency/buffer size until you start to hear pops and clicks then increase it one setting. Watch your pc overhead though as when you drop the latency/buffer you can increase the load on your pc.

Also are you interfacing the Peavey and Pod via USB to your pc? Two devices on a USB can cause problems for audio (not always though). Other biy for USB - there are different types of USB - USB 1, USB 1.1, USB 2. You really need USB 1.1 as a minimum and preferably USB 2 for audio . USB 1 is too slow here and will cause bandwidth problems, latency, drop outs, pops, click and so on particulalry if you share it with any other USB device. Also if you're using a usb hub it's best that it is self-powered rather than pulling off the buss.

Last bit - did you know that you can set a latency compensation in Reaper? Options-Preferences-Audio-Recording. Probably already defaulted to auto adjust for recording latency. Once you arm the track to start monitoring for recording the latency compensation should kick in.

Cheers,
Tony

All great advice Tony smile.gif

I'd just like to emphasise that in my experience you shouldn't have to adjust the latency yourself, especially with the Pod, if all is set up correctly you shouldn't have any problems, so exhaust the other possibilities around drivers and such before you go down this route.

Tony solved all again biggrin.gif
Thumbs up!!!

Sorry, I meant you shouldnt need to adjust the latency compensation ... adjusting the latency settings to eliminate pops an clicks as Tony described is something I do fairly often (you need higher latency for more complex mixes, lower latency for recording)

Posted by: tonymiro Aug 8 2007, 02:32 PM

Andrew's right here, I wasn't being clear before. The check box for auto latency correction should be checked and if so it's ok. If it isn't check it. YOu can of course play around a bit with the setting if you want and maybe put it back to auto later biggrin.gif . Must admit I tend to play with settings quite a bit just for the hell of it. Sometimes I remember far too late that I should have made a note of the settings that worked before I goosed it all blink.gif . Every now and then I even remember that I should rtfm, well I remember that I should but don't laugh.gif .

BTW the Reaper wiki has some great video 'how to's'. Great for people like me who can't/won't rtfm.
Cheers,
Tony

sweet man I got it to work. Lol found out I wasen't even using the pods asio so I just switched it over and it sounds great and no delays thanks everybody. And thanks for makin a little easier to understand tony.

Excellent, glad it is working, looking forward to hearing some killer tracks soon smile.gif
