New Interference with New Computer.

23 posts in this topic

I got my Tascam connected to my new computer. I downloaded Audacity and tried it out. I get a regular interference blip which I recorded for a diagnosis!

It's on both mic and guitar in. On this recording I have boosted the sound with volumes on max and some compression so its easier to hear. I don't think the hiss is a problem at normal levels, but the bleeping is. It never happened on my old computer. I've switched off lights etc and nothing got rid of it. I'm guessing its the 50Hz thingy (don't know anything about it, and even less about how to get rid of it!)

I'm going to download Reaper now to see if it's there as well. In the meantime, any suggestions would be much appreciated. Thanks in advance. :)

Carol,

I used Audacity for a while but can't really remember, does it have a built in metronome? That sound is cyclical but sounded an awful lot like a midi metronome. Sorry I couldn't be more helpful, but I am sure someone will be able to assist.

Hi Knight, I looked to see if a click track was playing - no sign of one from what I could see. When I get Reaper going, that might give a clue. :)

Bad news! I'm getting the same bleep in Reaper as well...:brickwall:

and for those that were reading the other thread about Vista, the courier has lost my Macbook...I'm having a bad week!

Which Tascam have you got Carol, I'm having a bad week Courier wise the Aardvark soundcard I bought from the US in April is still floating around somewhere I'm having an argument with the Courier at the moment who vaguely know where it is, I used all my swear words up on them yesterday.

Anyway you mentioned the 50hz thingy is that to do with the wordclock is that mentioned in the manual at all, that sound is very consistent.

That definitely sounds like some kind of metronome, Carol. Does the Tascam have a metronome or click track of some kind built into it?

It doesn't sound like the default click track that Audacity uses - it's much too low-pitched - so I'd suspect it's coming from elsewhere. The fact that you got it in Reaper too leads me to believe it's in the Tascam somewhere. I haven't messed with midi yet, so don't know if the wordclock could cause such a thing or not.

Sorry to hear about the troubles with your lost Mac, too - hope it all works out for you!!!

That sounds like a kick drum. perhaps the click is sending out a MIDI note being picked up by internal sounds.

I don't think it's the Tascam because it doesn't have its own metronome or click track - I haven't loaded the software package that comes with it. The other thing is that I haven't changed anything on the Tascam and I didn't have it before. Today I'm going to try plugging straight into the computer via line in (not using the Tascam) and see what I get.

I'm not sure what effects the 50Hz might produce - I think its the current (?) used by household electricity systems that can sometimes be a problem (what sort of problem I've no idea).

It crosses my mind that my old computer is sitting there unused (possibly feeling rejected?) and sending bad vibes? If I was getting my Mac I could have used that for recording.

If necessary I could use my old computer for recording but that would be a pain and take up all my space and patience.

PS It's time my hardware learnt who is the boss around here :devil2:

I've just timed it and it's at 100bpm so maybe that would fit with a 50Hz problem (AC current?) OK, I'm waaay out of my depth in the Physics department here :laughingg:

You're outside of my depth of expertise also, but I've never heard of household current causing a rhythmic sound like you recorded. Over here our AC current is 60Hz, and it usually manifests itself in a 'hum'.

That is a very strange problem.

I've never heard 50Hz/60Hz buzz do that either. This is what 60Hz buzz sounds like:

I don't think it's a metronome/click track either. Especially since it is doing that in Reaper, because that is definitely not Reaper's click sound.

You're using Vista, correct? If so, I'd say look no further. ;)

Do you have the latest driver for the Tascam installed?

Hi Tekker, I'm on XP Prof SP2 (AMD not Intel). It has to be the computer itself because if I click Record on Freecorder, I get the bleeping with nothing at all plugged in. My computer has its own heartbeat!

OMG!!!! It's gone!!!!! I'm going to experiment with every light and power source in the house!

Awwwww, we don't get to blame Vista for it??? You're no fun at all! :lol:

Go pick on some other PC Stratrat- my PC is coooool - and it sometimes has a heartbeat :wow: - I bet no MAC has that!

Besides, MACs clearly have a mind of their own and can go off with complete strangers - even couriers!!

(and we don't mention Vista within earshot of any of our gear) :winkthumb:

Yep - must be the influence o' them free-thinkin', sandal-wearin' hippies up in Cupertino that build 'em! :yes:

I've been messing around a bit with GarageBand when I have time, trying to put together a backing track to play over. As soon as I manage to sit down long enough to get something together, I'll post it. I'm going to see if it has a "heartbeat" effect in there somewhere just for you, Carol! :D

Darn, and I had a whole bunch of Vista wisecracks ready to go.... Oh well. :dunno:;)

My beeping is back and I've been experimenting. I can't find the source but I can get around it by having guitar vol almost max (I get a hum if the guitar is on max), the input on the Tascam very low and then add gain after the recording.

About Reaper:when I arm a track for recording, there is a number at the right hand end of the window that opens. On my settings it varies between -70 and -20 and it changes for no reason I can work out. I'm curious about what it is.

Also, what are the ave sort of settings for sampling for the basics of ave recording quality? (there seem to be dozens of different types of sampling and a wide range of choices) and......does dither (and other things) and all the tweaking options they give you really matter?

I don't think I've seen a Tekker lesson with guidelines for these things, but if I'm wrong, a pointer to where they are would be great. Thanks in advance:winkthumb:

That is a number value for your volume. If it's changing then your signal level or the noise level is changing.

16-bit 44.1kHz is standard CD quality. You can record at higher bit rates (24 bit) and higher sample rates, but you will have to convert back to 16-bit and 44.1kHz to put on a CD.

Personally I have not done any experimenting at higher rates. But I have heard that 24 bit gives much better results. Whether or not higher Sample rates makes much of a difference has been debated back and forth among high-end professionals. Some say it makes a difference and others say they don't notice enough improvement to warrant the larger file sizes that get recorded. But 24 bit seems to be the best bet across the board. I may have to give this a shot and hear the differences for myself. :)

Dither does make a difference if you recorded at a higher sample rate and convert back to 44.1kHz. But if you initially recorded at 44.1kHz then you don't need to do it. If you do try recording at higher rates, you want to make sure that dithering and converting back to 44.1kHz are the very last steps you do before burning your CD. This way all your effects and mixing is calculated with the higher rates.
