Re: Waveform not symmetrical

"The way I see it, you have two options right now. 1) Tell us the model number of the stereo amp you have and we can try to find a manual online. You might have the output you want on there, but it may be labeled with an odd name. Audio electronics (especially older models) are like that." Well, don...

Re: Recognize noise in a waveform.

Quote " Proper playback only happens when the needle is suspended carefully between the two walls of the groove. The needle doesn't touch the bottom of the groove--ever. " (Maybe the following should be a different thread.) I am sure I read that the new "gramophones" don't have a needle anymore to p...

Re: Recognize noise in a waveform.

Serious pops or clicks are "spikes" either up or down on the blue waveform. They usually are pretty large and significant compared to the musical performance. However. If the pop is not serious, you will never be able to take it out manually from the blue waveform. OK, I might be able to do that, b...

Recognize noise in a waveform.

After recording from a vinyl record, viewing the waveform gives me no clue where the noise is. The noise I am trying to edit out, using "effect", is the crackling noise of the needle in the groove which occurs periodically. Not consistently. Does anyone know the waveform pattern of the noise that th...

Re: Waveform not symmetrical

Quote: "Ideally you would connect the pre-amp out to the line in - that is, before the power amp. A speaker output is not designed to go into a line input, " How does one connect to the pre-amp? There are no convenient jacks, like speaker jacks. So should I clip onto the internal wires coming from t...

Re: Waveform not symmetrical

Quote: "No Phono Preamplifier in the middle? Do the transfers sound OK, not high and peaky?" The record player is part of an stand alone old-fashioned stereo system. The Line Input of the computer soundcard gets its input via a red-white cable which is plugged into the back of the stereo. Those same...

Re: Waveform not symmetrical

It sounds like a hardware problem - something like a capacitor breaking down and putting a DC voltage on the audio input, which gradually (exponentially) returns to the correct level (zero DC offset). Can you test the line in of your soundcard by connecting a different audio source to it? I tested ...

Re: Waveform not symmetrical

Are you using a dreaded, evil USB Turntable? Koz No, I am using an old-fashioned turn table which does not have an USB connector. The 2 conductor red white cable connector inserts into the plug of my computer i.e. line input. Also very recently I installed a new stylus on the record player, just to...
