Input on right channel only??

New to Mac, Mainstage, but not new to recording. I just don't know a ton about how to use this stuff.
I've got my acoustic plugged into a basic M-Audio USB interface. Interface into the USB port on my Mac Book Air. MainStage is set to use the Interface as Input/Output. I play, I hear it in my speakers, it's all gravy. EXCEPT... In stereo, only the right channel shows any input! The reverbs come out stereo, which sound very nice, but it's as if the guitar itself is somehow panned to the right. I don't get it.
If I record it and play it back, it sounds exactly the same. Main signal comes out of the right speaker, but all the reverbs/delays come out stereo. It's a trip.
If I set the thing to "Mono" then I get nothing at all.
Anyone?
Thanks for dropping any help you can give.

Oh, I didn't just blow out the speaker. I would know, because I was using headphones at the time. I also made sure right away to test with other devices being played through the analog stereo 1/8" input. All play through JUST the left side, regardless of output device.
However, sounds/noises/music/etc. generated by the computer itself (iTunes, movies, alert sounds, and such) are all stereo.

Can I copy right-channel only content to the left channel?

no. what are you trying to accomplish?

Audio input issue - No stereo... Right channel only.

Hi
First to thank you for taking the time to read and consider this if you do - any help in this would be hugely appreciated
Ok - I'll try to make this as concise as poss but it needs some explanation:
I'm home-recording hobbyist musician. One of the things I would very much like to use the iMac for is to back up old four-track tape recordings, recording them as wav or mp3 as the case maybe and saving them to my hdd. Easy right? Apparently not, so far... let me explain:
On the tape recorder there is only an RCA stereo out (red and white, left and right). The very first thing I did when I got the iMac was download Audacity (the audio software), hooked up a stereo lead to the RCA outs on the tape recorder, and ran it into the line-in port on the iMac, using the 1/8" jack.
Now, sound came in, but only the right channel. The left channel was completely dead (ie when I panned the audio to the left, or if there was a sound in the mix that was only in the left channel, it was absent).
Since then I've bought Logic Pro and and an audio interface and this presents the EXACT same problem... Nothing in the left channel. (please note, I am aware you can "fake" stereo by setting a channel-strip to "mono" so that there is sound on both sides, but get this - it only splits the right channel in two - so you still don't have the left channel or genuine stereo signal frustratingly)
It should be noted that stereo sound is not a general problem on the system. Stereo output is perfect (ie on itunes, cds, online etc - or if I'm using softsynths in Logic for instance) it is solely an AUDIO INPUT issue.
Needless to say I've explored all options in sys prefs to no avail.
It should also be noted that I have also tested the actual output of the tape recorder and used the same leads to line into a home stereo system no problems.
Does anyone have any idea what I'm talking about or how this could be resolved? I am even open to suggestions for peripheral equipment, sofware additions etc - any questions at all, just ask.
Thanks again, any input would be welcome.
EDIT: I also posted this in the general iMac forum. Posting here for people w specific audio knowledge thanks!

Pancenter, thanks once again.
Sorry about delay replying - have had an internet outage here just to add to my woes haha.
Anyway, the good news is that I think I've cracked it:
After updating the OS per your suggestion, uninstalling both Audacity and the m-audio (profire 610), and lastly resetting defaults on sys audio midi prefs I was still experiencing this problem - just on a line-in to Garageband. Pure frustration.
So eventually I just elected (in lieu of chucking the hardware out the nearest window lol) to do a cold re-install of the OS (erase and install option, backup hdd done). As I bought the iMac in January the OS is 10.5.5 I think.
After install, before doing anything else at all, I opened Garageband, set up an audio track and set input prefs to Line in Stereo 1/2 etc, and hooked up the tape unit via rca and the line-in port. The result? Perfect 2-channel stereo.
My personal theory is that the problem was created by the audio interface installation - an m-audio "profire 610" - Tho Audio interfaces are a frickin minefield anyway between Macs and PCS, chipset compatabilities, dodgy beta drivers, worthless gadget-hawking etc etc... I also realised that while my first original attempt was on Audacity I had already installed the profire unit just immediately before (but didn't use it). I doubt it was Logic which is designed specifically for the mac - I feel this theory might be proven when I reinstall these.
So there you go - get the Audio interface right it seems.. And I've got stereo audio.
Thanks for your help and input Pancenter - much obliged.
Peace.

EQ in the right channel only

Hello
Yesterday I had my 4 year old son as assistent.
Using Behringer 2442.
After the session I noticed that he had raised
the EQ mid to +6dB and the Freq stood in position 800 hz on the mixer.
It was 2 monotracks panned L & R. It was only for right channel that he EQed.
The left channel is neutral. Is there any way to restore this recording
in Logic?
with regards Nygade 48

Luckily for you the "Pan" control in Logic's mixer is actually a "Balance" control when using stereo tracks, which I am guessing you're using.
So if you simply make a new stereo channel in the arrangement, and make a copy of the offending region onto it (so there are two side identical regions). Then in the mixer pan the original left and the new duplicate right, you should hear exactly what you were hearing before making the duplicate, but now you can apply an EQ to one of the channels and it will only affect the left or right channel independently.
Next time check your employee's qualifications!

I am getting audio from the right channel only my iPad and it is distorted with static. How can I resolve this problem?

How do I adjust the audio output of my iPad? There is sound only from the right channel and it is distorted with static.

There is no adjustment as the iPad 2 speaker is on the right side only.

Sound messed up right channel only not the headphones

Anybody else have this problem: When headphones are plugged all the way into the jack only the right channel works. Pull the headphones slightly out of the jack and the left channel works. Both channels sound a little faded. Tried other headphones and same problem.

yea i have the same case, i was thinking that might have been a problem. yea i have to send mine back again the second time for the same problem. I think if Ipod just made them right in the fist place mabey they could save some money on all the returns. good luck with your ipod. and remember if you send it back more than 3 times apple sometimes gives you some free loot.

HUGE audio problem - Right channel only?

Editing i hear both channels or atleast 1 channel split. Regardless, after i export all of my clips except some sound loops/musc is on the right channel... What happened?
Had a video where only some clips(coincidently from a certain camera) were all right channel where as all other clips where both channels.
Confused. Give me some help over here.
Thanks

You got it!
That solved evrything.
Now my next audio thing is that my footage will come in one one side(left channel) so i have to put it from stereo to dual mono. However that is due to a setting of recording on my cam im sure.

Left /right Channel balance

Not a specific Logic question as such, more a general one on sound balance. Have been using a pair of Klipsch speakers for about a year now and have started noticing a decided swing of volume to the left hand channel when everything is set to centre like drums etc. Tried swinging a drum snare to the left and right and the right hand channel is just so much quieter to the point of al most losing the snare ! Tried it on my headphones and its the same. Could my mac be giving a hiccup?

Hi,
You might do well in calibrating your audio outputs.
Here's a quickie:
1. Turn OFF your speaker system. Failure to do so will not only blow them up, it might get you evicted...or thrown out from your parent's...or the neighbor going after you with a shotgun, you get the picture. I won't be held responsible if you skip this step, and become deaf as a result.
2. Open a blank Logic song, and make 1 track. Insert a tone generator plug-in,and set it to 0dB (the maximum output level). Make sure the pan is set to centered.
3. check your audio device's output level meters. they should MATCH. If not, there is an issue with your audio device. consult the mfr to get this fixed ASAP. If this step is ok, move on to no.4.
4. If you have a mixer after your audio device, look at the INPUT GAIN on the channels that your main outputs from your audio device are fed into. Put the left channel into SOLO, and calibrate the input gain so it clips, and tehn back it off just slightly, until no clipping occurs. Do the same for the right channel.
5. Set the OUTPUT of the mixer faders to 0, and pan each channel hard left and hard right, respectively (ch1 left, ch2 right, etc.)
6. Look at the mixer's OUTPUT meters. Do they match? If they do NOT match, you need to contact the mfr of the mixer, and have this fixed ASAP/ If they DO match, then proceed to step 7.
7. Look at the amplifier that your speakers are hooked up to : does it have an INPUT gain knob? If it does, then you can calibrate your speaker amplifier. If it does not, REPLACE this speaker amp with one that DOES have input gain knobs. If it does have input knobs, you now can calibrate the speaker levels. Go to step 8.
8. With a good SPL (Sound Pressure Level) meter, place the meter on a mic stand or other sturdy device, and place it in your mix position, pointing towards the exact middle of your speaker spread (exactly between the speakers). Turn the meter on, and set it to read 80dB sensitivity.
9. Set your mixer's monitoring output (the one that turns the output up and down to your speakers) SLOWLY... until you get 80 dB on your meter.
10. MUTE the right speaker output. You can do this on your mixer, by muting the left channel. then turn up the monitoring level up until you get the same 80dB. What is the level difference? Note this.
11. MUTE the left channel, and turn on the right channel. turn up / down the monitorin levle until you reach 80dB. What is the difference? not this too.
12. On the speaker gain knobs, notice where they are BEFORE you calibrate the speaker amplifiers.
13. Put your monitor level back to about 10 am position. This one is the one on the mixer. NOt the one on the speaker amp!!!
14. While still on the RIGHT channel only playback, notice where the level meter is now. Adjust the RIGHT speaker input so that it reads 80dB upon playback at the 10am position on the mixer monitoring knob.
15. MUTE the Right playback, and turn on the Left channel playback. notice where the level meter is, and adjust the LEFT speaker input until you get the 80dB.
16. Now, turn on BOTH Left and Right channels, and it should be louder than each channel separate.
17. Adjust the monitor level knob on your mixer until you reach 80dB. MARK THIS SPOT.
You now have a calibrated listening system.
Enjoy

Premiere Elements 13 (not Pro), recorded a video with mono mic input (left channel only), need to create 2-channel (left and right) audio track for finished product. Help?

The question says it all. I have been all over the tutorials as well as the menus inside Premiere 13 and cannot find how to edit the audio track beyond basic balance, volume, etc.
I can see the Audio 1 track, shows audio in left channel only, but it will not respond to attempts to select, cut/copy, paste, etc.
Basically I just want to turn one-channel audio into two-channel audio.

Sure you do not want to give the Fill Left and Fill Right another try?
According to the Adobe document Adobe Premiere Elements Help | Effects reference
Fill Left, Fill Right
The Fill Left effect duplicates the left channel information of the audio clip and places it in the right channel, discarding the original clip’s right channel information. The Fill Right effect duplicates the right channel information and places it in the left channel, discarding the existing left channel information. For example, you might use this effect on footage shot with a monaural microphone plugged into only one channel of a camcorder, extending the voice of a speaker from one channel to both.
From what you wrote, your Premiere Pro video seems to be saying the same.
If that Premiere Elements Fill Left or Fill Right is no go, you might want to explore what you can do in this regard using the free audio editor Audacity.
Audacity: Free Audio Editor and Recorder
And, then import the Audacity edited audio back into Premiere Elements project as source media.
Is the speaker system OK?
We will be watching for your results.
Thanks for the follow up.

Power Mac G5 Audio is outputting only the right channel

I have an audio problem with my PowerPc Audio card, I presume. It is only outputting the right channel. I have a set of computer speakers and when I go into System Preferences and move the balance slider, there is only sound coming from the right channel. Absolutely nothing from the left.
I found this problem when editing in FCP and needing to do a split track with VO on channel 1 and Nats and music on channel 2. I could see the meters showing the audio output from channel 1 but no sound coming through the Mac's left channel output.
Also, I have a DeckLink extreme card in my system and when I test the L-R channel output I get the same problem. I do not know if the decklink is somehow using the Mac audio card for help with its output. I would think that it is using its own hardware for generating the audio output from the card.
Hardware issue? Time for a Mac Genius repair? Don't know if there is any workarounds or fixes before I go that route. Any help would be appreciated.
Thanks
Doug

No I didn't but I run my Mac's output into an analog mixer and then out to my speakers.
When outputting through channel 2 only, both speakers work, yet when I pan to channel 1 the sound drops out. As I pan from full channel 2, where both speakers are up full, you can hear the sound fade out.
Also, I got the Deck Link card to work through my mixer. The L and R channels are outputting through separate inputs in the mixer and work independently and correctly. I even changed out the mini stereo cable just in case and still no left channel out of the Mac.
Very weird! I've even repaired and defragged my system disk in case it is some sort of corrupted code. Just grasping at straws before I take it to a Mac Genius.
Thanks for writing. I appreciate any and all suggestions.

I'm using GarageBand 10.0.1. Do the built-in drum tracks only come in mono format, or is it possible to make them true stereo (i.e. Left and Right channels outputing different signals, to sound like the kit has been panned across the stereo field)?

All the Drum Kits available for GarageBand are mixed in stereo.
Logic provides the same 18 Drum Kits also as "Producer Kits", which are multi-track outputs,. Each Drum Kit Piece (Kick, Snare, HH, etc) and also room mice and overheads are routed to individual channel strips.
Here is a screenshot of one Drum Kit in Logic Pro X with individual Channels Strips. Each Channel Strip can be loaded with individual effects (compressor) and adduced with individual sends, etc.
What that means is that all the Drummers are professionally recorded and sampled with individual mics. The Stereo Drums Kits are just "stereo mix-downs" for easier handling and less CPU demand. I explain all the details about the Drummer ecosystem in my graphically enhanced manual "GarageBand X - How it Works"
Hope that helps

Audio Input on the Left Channel is fine, Right Channel, Not So Much...

Okay, so I'm attempting to record some audio into my eMac using it's 3.5mm Line Input Jack, but Sound Studio is telling me that all of the audio is coming out of the left channel.
I checked balance, it's a new cable that works fine otherwise, the device I'm recording from sounds fine on headphones.
Any suggestions?

Hmm. I think someone more technically-inclined with audio could help you out here. I tried recording audio on my eMac with QuickTime Player (I'm not sure if you need QuickTime Pro to do this, otherwise I would suggest you try the same thing). I have a similar experience as you. The QuickTime A/V window (control-K) informs me that the audio balance is shifted completely to the right channel (rather than left, as you observe in Sound Studio). And there is no way to adjust this, it is also "greyed out". This QuickTime recording is through the built-in microphone on my eMac. Might there exist (pricier) external microphones that are specifically capable of stereo recording? Or perhaps our eMacs aren't capable of stereo recording, at least without hardware modifications. I don't know. Clearly, I'm ignorant about this. Perhaps there is a Discussion going on somewhere else around here that is more Audio-specific?

My external audio recording device only records to the right channel. How do I send the sound in the right channel thru the left one in Final Cut to get a full stereo sound?

My external audio recording device only records to the right channel. How do I duplicate the sound in the right channel and run it to the left one in Final Cut to get full stereo sound?
I've already copied and pasted the right channel (A2) onto the left channel (A1) but that just doubled the volume on the right channel.
For instance, when I listen to my audio with headphones it only comes thru the right one. How do I make it so that it comes thru both headphones?

Stereo is something else. It is a sound field where the individual elements are located through varying the amount of electrical energy for each element delivered to each channel.
What you have is a mono source that should be panned to center. This will equally divide the signal so it will be delivered out both the L & R channels.
Load the original clip to the VIEWER and set the PAN to 0 (zero). Delete any duplicates. They are unnecessary.

Only recording on right channel

I have an apogee duet and I'm hearing audio, but it's only coming through in the right channel. How do I get it to go to both?

)Re: Line In Recording Left/Right ChannelleI use Adobe Audition. I played arround with my settings and found out that to mute the right channnel or unmute it does not effect the li've-playback of line in. Only the left Channel (mute / unmute) has an effect. So if I put an Instrument on both channels, both channels go through the left channel while playing. If I put an Instrument only on the rigt Channel I hear nothing. If I put an Instrument only on the Left Channel I can hear it. So for li'veplayback only the left channel works. Recording uses two channels. I found out in the Audio-Creation Console of the Xfi- Titanium that, looking at the Playback Volume Meter, only the left channel shows something, while? the Record Volume Meter shows something on both channels. It seems that the Soundcard handles realtime-playback of line in and recording of line in different. Realtime - playback of line in seems to be mono while line in recording seems to be Stereo. Is there maybe a switch or a setting to get realtime playback of line in to stereo? Is it a driver problem and realtime Stereo isn't supported by line in on the X-fi?

Speaker jack only plays right channel

Hi everybody,
since a few days when i plug my speakers or earplugs into the speakers-jack, only the right channel has been playing. I already checked "balance" in the system preferences - it is centered.
Can someone help me with this?
Thanks.

Hey thanks for replying so quickly. Could have been the solution (jack in/out too often). Though my problem was solved in a different way a minute ago:
After plugging in my earplugs again i just realised, the balance-settings automatically change depending on which output you use. So some days ago I must have been dragging the balance-fader to the right and unplugging the speakers then the system auto-saved.
So you always have to check "System Preferences / Audio" with the plug inside the jack.
