what is wrong??? I get glitches!

    I've got a Juli@ sound card and have always recorded with it using synths through audio cables, just the regular stuff, but I've had for quite some time a problem of a certain glitch in the sound (a scratching type of sound) at random parts in my recording.

    I'm using Sonar 3, and have used it for many years, but when I changed from my old AMD PC to a Core 2 Duo pentium, I cannot record long stretches without getting this annoying noise (very abrupt but short) and I have to start all over again...

    at first I thought it had to do with the adapters I was using, since the Juli@ has 2 options for recording: you either use RCA connection or regular plug one. I tried switching from one to the other, but it's always there.

    now, mind you, I don't mean it is ALWAYS there, it just happens ramdomly, like I'm recording for some time and all of the sudden I get it, and it's NOTHING I CAN HEAR, but I only see it once I've finished the take.

    what I did notice some days ago, is that when I was playing (not recording) my synth connected to the computer, I heard an almost imperceptible STOP in the sound and then it continued. my guess is that's the very glitch I'm getting!!!!

    any ideas? is this a configuration/driver problem?
    could it be the mother? it's an ASUS
    could it be the hard drive?

    any help will be greatly appreciated!!!!

    Don't record to your system drive.
    Don't have unnecessary junk running while recording.

    There's zillions of threads on how to optimise a PC for recording, just laying around on this forum.

    Get a second internal hard drive on its own cable and port to record your audio to. Alternatively you can get a USB hard drive (7200rpms) to do the same. Also change the temp folder in Sonar to the recording drive.

    Continue browsing the forum to find the sticky about optimizing your PC for audio-especially turning off all networking components by disabling them.

    what do you think about this setup?

    Pc Intel Core 2 Duo E4300 1800mhz
    mother ASUS p5vd2-x
    hd maxtor 160gb sata2
    2gb ram memory
    sound board juli@ (egosystems)

    I have always recorded in 24bits and 96k

    besides getting an additional hard drive to record into, should I get a BETTER MICRO CHIP? let's say I had the budget to get a CORE 2 QUAD, would it be worth doing it WITH THIS MOTHER BOARD? I mean, would I get better results and more speed or would the motherboard just bring everything down in performance?

    I use win xp, what about perhaps also adding 1gb or ram memory? (someone told me it's the maximum used by the xp)

    I'm aware that this kind of question also pertains to other areas besides recording (general pc performance), but since I'm asking...

    My opinion which is not shared by all my fellow pc gear heads, is that 4 gigs is best-meaning two matched sticks of 2 gigs each. 3 gigs are recognized by the OS so maybe it's overkill, but I always use matched sticks after some less than satisfactory unmatched pairs I've had.

    According to the quick specs I read, your board doesn't support quad core but you could get a faster duo core. That isn't necessary though. You have another SATA connector and two IDE connectors on that board. Get another hard drive and cable and plug it in all by itself on that channel. That will improve your performance drastically as your system cannot read and write to the same drive at the same time.

    OS drive (c: usually) for OS and programs.

    Secondary drive for recording destination and DAW temp files.

    maybe your need to change your buffer setting to something like 256 or 512 when recording your synth????
  7. ferchis

    I see two things, as far as I know, related to this in the Audio options window in Sonar:

    1_ mixing latency, which gives me the option of managing the "buffer size" from FAST to SAFE, should it turn it all the way down to SAFE?


    2. probably what you mean, at the advanced audio options section, I see a tag for "file system" which has a clear option to set the [I/O Buffer Size (KB)is THAT latter which I should turn into 256 or 512? also, there's the option of enabling READ AND WRITE CHACHING, should I do sth about them too?

    I'm desperate!!!!!!! I used to record in my old Athlon 2.0 with only 786mb of ram memory at immense stretches without getting a single problem!!! now with a newer computer, I can't do it!!! and I did it ON THE SAME HARD DISK!!!!

    The hard disc isn't the issue. The motherboard and other components playing nicely together is the issue. You have digital artifacts occurring so something is conflicting with the Juli@ or bottle necking the hard drive bus. Check your IRQ settings and get another hard drive.

    Check these links for streamlining your pc:


    The first one I use and the second looked reasonable enough for me to bookmark.

    It could as easily be Sonar 3 that is at fault. Have you (OP) considered this?
  10. ferchis

    ferchis Active Member

    well, now I can officially say that it ISN'T the BUFFER SIZE, etc etc, since I increased it to 512 in sonar and still get the glitches...

    you know, I forgot to mention that some times, BESIDES getting the annoying little noises in the recording, it sometimes happens that the recording STOPS and I get a message that the audio disk may be full... before you ask... OF COURSE IT'S NOT FULL!!! i still have plenty of space, and I have also tried now to free more, but it did remind me of the HARD DISK suggestions...

    could it be, after all, that my hard drive (maxtor btw, which I've been told is not good at all...) ISN'T actually capable of reading and recording at the same time, or sth like that, so I should go and get a second drive??????

    if that's not it, perhaps the MOTHER BOARD?

    PLEASE!!!!!! my recording life depends on this!!!!!

    any other ideas?
  11. TheJackAttack

    No hard drive is capable of reading and writing at the same time. You are sending more data to it than you have before and that is why it is faulting out. GET A USB HARD DRIVE.

    Just for the record, 512 is not that big of a buffer in many cases. It may be big for a decent PCI bus but again, it's the fact you are overloading your IDE bus.

    Your disc may not be full, but you may be out of continuous data space. Try a defrag a few times to straighten a few things out.

    EDIT: But also...get an external ^

    Well, instead of huntin' and peckin' maybe this will be more help to you:

    search engines

    So many variables, it is just to complicated to say without missing something...especially when you aren't giving as much help to those trying to help as you could ;)

    You never addressed this post and it can be one of the MAIN reasons why people get drop outs.

    I would get out of crisis mode and try to relax, but that's just me ;)

    thanks space, you see, I actually paid attention to the advice on optimising the pc, did a lot of fiddling around with parameters, still get the same thing, that's why I didn't say anything...

    and... I DIDN'T say I got dropouts, since I have already solved THAT problem some time ago by increasing the buffer size, as someone also suggested here, the problem is that the machine KEEPS RECORDING but when I finish a take, I see the bumps in the visual display of the take and HEAR THEM as well!!!

    if you asked me, it looks as if the disk is not able to cope with the whole thing... but that's what's amazing, since I used to record with my old amd pc some years ago, using the juli@ card, and NEVER got anything like it...

    the cables/audio in port of the board are also out of the question, I've already tested almost (if not) everything in relation to them

    I'm going to read the sonar help link you gave me, cheers!

    Just a note - you could've said you'd optimised various parts of the system. This way we know that it isn't MSN running in the background.
  16. ferchis

    ferchis Active Member

    it surely isn't... I just don't know, I'm not even sure it's the hard drive.

    I think I've mentioned that this NOT ONLY HAPPENS WHEN RECORDING, it seems to be a technical/configuration/HARDWARE problem, since I was once JUST PLAYING with the synth connected to the pc (not recording) at a relatively loud volume to check sth in the sound I was about to use, and I NOTICED A MINUSCULE, almost imperceptible STOP IN THE SOUND!!!! it was just a second, and then the audio went on playing...

    the way I see it, it was the same GHOST haunting me!!!!! because that's the way this thing works: it's sporadic, not systematically happening in regular intervals or sth of the sort

    that's why I keep thinking about the mother board... it's ASUS P5VD2-x, should I expect anything to go wrong with it?
  17. TheJackAttack

    TheJackAttack Distinguished Member

    The Asus P5 series in some incarnations has been used for audio for a long time. It could be the board or it could be a short in the Juli@ if it has age on it or was spiked while being handled. Additionally, if we are just talking system issues, if there is not sufficient ventilation then too much heat can cause ghosts in the machine as things begin to fry out.

    ferchis Active Member

    well, the ventilation MIGHT be, but I'm not so sure, since I've never had any issues regarding that, I mean, any overheating or similar.

    I bought the card in 2004, does it mean it's old? already??? what exactly do you mean by "spiked"?

  19. Guitarfreak

    Pretty much. 5 years is a lot by today's standards. For gaming, 'top of the line' video cards only last for a year or two at best. I can't imagine this would be much different.

    We're always looking for ways to make things better, faster, cheaper.
  20. Codemonkey

    Codemonkey Well-Known Member

    Actually they last for maybe 5-10 years.
    They become too slow for the current standards after about 2, but the card still works.
