Hai these are Hiss sounds,.all u need is a noise reduction plugin,.

audacity is so basic will not help u,.

and adjusting EQ will make u r sound missed in freq,.

if u want high quality playback without hiss,popup and noise.

do record via Soundforge it has noise cancelling in recording setting it self,.like it chooses noise floor and start recording above the noise floor decible rate.and plus it also has a noise reduction plugin,.



get online help.,i will give u some cool links read those articles.



wishes,

It's virtually impossible to make vinyl tracks sound "CD quality" no matter what you do. If the records are scratched, they'll sound scratched when you upload them to Audacity. However, with a bit of work you should be able to improve them somewhat.



Let's start with the sound source. If you're running your record player through an amplifier, check that the EQ settings (treble, bass etc) are "flat", that is, set to 0 or neutral. If the sound is still muffled, try putting the treble up and the bass down a bit. Make sure all the cable connections are firm (try twisting them in the sockets to remove corrosion). And, most importantly, check that the record player needle is free of dust, as well as the records.



Next, make sure the input signal to your computer is nice and loud. Assuming your vinyl player is plugged into the Line In socket on your computer, the selected input source should be "Line In", not "Stereo Mix" or anything else. Click the recording level meter in the top right corner of Audacity to monitor the input signal (if the record is playing, you should see the red bars moving). Use the recording level slider to bring the audio signal up so it hovers around at about -12db, or as high as you can safely make it without EVER letting it touch the right end of the meter, even in the loudest parts of the song (this is very important).



After uploading to Audacity, you can sometimes improve the quality of the recording by trying out the Noise Reduction feature in the Effects menu. Select a "silent" piece of audio with just the static, click on "Get Noise Profile", then select the whole track and apply the noise reduction. You can move the slider to experiment with different amounts of noise reduction - I recommend starting near the low end. (Remember to undo the effect before trying it again.) However, if the static is too loud you will probably hear noise artifacts (weird whistling or watery sounds) even on low levels of noise reduction, so be careful. You can undo any changes you make.
