1 Channel Seems To Be Higher Than The Other.....

Post by jb3funk » Tue Aug 23, 2011 9:21 am

Hi Guys!!!

http://imageshack.us/photo/my-images/88/waveform.jpg/

As You See From The Picture Above,1 Channel Seems To Be Louder Than The Other... (Even Though The Sound Seems Pretty Good)

I Dont Know Why This Is As I Have All The Levels Correct On My Mixer (Ecler Nuo 5)

I Dont Know If This Effects The Sound Quality Of My Recordings? But I Would like To Know How To Fix This Problem So Both The Wave forms Are The Same

Hope This Helps

Cheers Guys!!!

Your overall recording level is way too high.
How is the Ecler Nuo 5 connected to the computer?
You need to lower the record level so that the maximum peaks are about half of the track height.
When you've done that (or ask if you need help doing that) please post a new screenshot.

Screenshots can be uploaded directly to this forum (see "Upload Attachment" below the message composing box).
When the picture file is uploaded you can insert it "in line" into your post.

I Have My Ecler Mixer Going Into Line In On My Numark xternal Soundcard (Not So Expensive)

The Numark Plugged Into My Laptop... USB...

When I Record My Vinyl Collection...I Have The Levels At -2 On The Mixer So It Does Not Go Into The Red Zone

As I Said,The Recordings Sound Fine But Something Is Wrong Along The Line

Click the speaker icon by the system clock > Recording Devices, then right-click over the line-in for the Numark > Properties. On the "Levels" tab, turn the input slider down (there may also be a balance control there to correct the channel imbalance). Double-check you are not connecting the mixer to the mic input, that would explain the excessive level.

If you cannot correct the balance problem using the mixer or "Levels" you can use Effect > Normalize in Audacity to do so but that will not correct any clipping distortion you may have due to excessive input level.

If you are hardware monitoring them in the mixer, possibly they do. The point seems to be that you need to correct the excessive input level after the recordings have gone through the Numark.

Have you tried the suggestions in my last post?

Is the sound also unbalanced between channels? If not then you can blame Numark for that. Presumably you can also increase its input level in Windows as I suggested?

The recording level is too high. Both channels are touching the top/bottom of the track and will be clipped (distorted) at those points (if it does not sound bad, then it's just not clipped to badly, but it will be clipped).
The right (lower) channel does appear to be recorded at a lower level, but it's impossible to see exactly what is occurring until you have a recording that is not clipped.

Also, I'd highly recommend that you change the default sample format back to 32-bit float (Edit menu > Preferences > Quality)
If the final destination of your recording is for CD, then it would also be best to change the default sample rate back to 44100 Hz.

We don't understand what is preventing you turning down the input level.

The Audacity input slider in your last image is on maximum but not greyed out, indicating you can use it to reduce the input level. This will prevent loss of audio data in the recording, while still letting you Effect > Normalize it afterwards to the maximum 0.0 dB without data loss if you wish. Effect > Normalize will also correct the channel imbalance - it will scale both channels to 0.0 dB so that the peak volume in each channel is at that level.

If you find after that the tracks do not sound loud or "punchy" enough, you can try Effect > Compressor to reduce the difference between loud and soft in the recording.

Ok...Got All The Levels Right This Time (I Think)

I Put The Input Level In Audicity At 2 Or So...

Picture Above Is The Latest Recording I Did (Still The Lower Waveform Seems To Be Slightly Smaller) I Dont Know If This Is Much A Problem As The Sound Seems Fine To me...

BTW...This Is Dance Music Now That I Am Recording...

Last Question About Normalize:

A Friend Told Me To Record My Songs At -2 On the mixer,Then Normalize It To 0 db To Get That Digital Effect (I Dont know If This Is True)

Remove Any Dc Offset...I Keep This Option Unticked Yes?

Thanks For Your Help Here

Regards
