FYI, I have a:

1.5ghz, 512 megs ram, 60 gig hd PC with a Studiophile 2496 recording in Cakewalk at 24/48.

So, I'm recording, and when I play it back, I get popping and clicking in a predictable rate; about the speed of a ceiling fan on medium speed if you were to touch it with your fingers while it spins. When you look at the waveform that was recorded close up, there are parts in the wave where it just spikes down to zero, then back up to where it was (there's the pop).

The thing is, I don't hear this while I'm recording... not till after I play it back. The frustrating thing is that is does this unpredictably... sometimes it does, sometimes it doesn't (I had it not do then do it back to back when recording, hitting stop, and recording again... and I changed NOTHING!)

The fact that I hear only after I play it back suggests that's an internal problem, otherwise I would hear the popping sound while tracking. I consulted the Studiophile trouble shooting, the only solution they offered was to try turning off graphics acceleration, which I did, and it still does it.

Any ideas? Anyone ever have this problem? I'm going to contact M-Audio later on today, but I bet that the help I get here will be much more prompt and much better than their tech support =)

Let's just see. Thanks in advance!
 
...just a thought ...could it be your recording software that's having problems during playback? Try exporting the song to a WAV and play it through a regular wav player. If you've still got the click, you'll know.
 
Nope, already thought of that. I can visually *see* the pops recorded into the wave file when I view it in a wave editor.

It's happening somewhere after it reaches the analog input and the signal is being turned into a wave file.
 
Play with the buffer settings in both your software and the audiophile control panel.

For instance, if I'm using WDM drivers, I have to set the Delta buffers to 128 or 256 samples (the Delta and Audiophile drivers are the same, I use a Delta1010), and then adjust my software to use ~50ms of playback buffer. If I'm using ASIO, I have to set the Delta buffers to 2048 samples, which is then inherited by all of my ASIO applications.

It was nice when they had different settings for ASIO and WDM in the control panel...but no longer.

Ah! There you go: finally you need help from us!

That may be an indication of VIDEO problem, if you are running PCI videocard. Some cards interfere with the whole PCI bus more than they should.
Cure: get an AGP card. Or at least borrow one to test.
 
Popping

I don't use windows amchines I use Macs, so I don't know about the matter the one guy suggest before-that some video cards conflict the pci bus. But, I can say that it sounds very much like you don't have your sapmle rates setup correctly somewhere-either @ the card, or the software, or somehwere along the line. Check any & all devices in your recording & playback chain, and make sure they are all set correctly. I sometimes will send audio signal into my ADAT Xt20, and lightpipe it to my 2408, then on into the Mac recording to Digital Performer-I don;t actully run tape anymore, I just use the ADAT for the A/D converters and record straight to DP. Once I was tracking a sax player and I didn't have DP set to recognize the ADAT as the sync (sample) source. I didn't hear any clicking during the recording, but after the session was over & the sax player had gone, I found all kinds of clicking in the playback. Luckily it wasn't serious enough to be heard in the final mix.

Too, like you said about the ceiling fan thing-I've got a field by my house with horses, and we have an electric fence to keep the horses in-electric fences work by running a ground wire into the ground. I always have to shut that off when recording, because I get a pop everytime the fence charger box hits its' cycle. So yeah you could have some kindof ground thing going on.

Good Luck
 
You know, I think it's Cakewalk 9.... I've tried recording on a couple of other software packages and don't have this problem, only on CWAP 9.

Strange.... *ponder, ponder....*

Click to expand...

Solution:

Turn off your ceiling fan.
