Using 1 stereo input as 2 mono

Hi... I have a problem to solve and I dont know if I can use a single stereo chanel as 2 individual mono chanels (individual record start/stop). If yes then how ? For example: There is 2 phones connected to one stereo inptut. tel1 is chanel left and tel2 is chanel right. is that possible to record phonecalls individoal or do i have to use the whole stereo chanel to record something even if it's mono.

I don't know that there's necessarily a built-in way to do it, but, you could certainl write code to do it...
If you just read from a recording source and break the audio stream into samples, they're interleaved left-right-left-right...so you could simply redirect every-other-sample to a file, and handle the two redirections individually...

1820m Stereo inputs split into mono inputs?

Hi,
I want to split the stereo inputs of my 1820m into mono inputs so I can record multi-tracks on Cubase. Is this possible?
Thanks in advance.

When you set up a strip in PatchMix, it is seen from inside Cubase as a stereo ASIO channel regardless of whether you use both inputs. Pan one hard to the left, the other hard to the right, and then work out your VST connections in Cubase, and route (say) the one you panned hard left to a mono Cubase channel's input, and the one you panned hard right to a second mono channel etc., then you can record each input signal onto different tracks.

Stereo Input=Mono??

I'm new to Garage Band and macs in general. I was using Adobe Audition 3 on a Vista based laptop and have just switched to a Macbook (black)I'm using the same set-up as I was with Audition. A Behringer (Xenyx 802 with 2 mics) mixer with L/R 1/4" patch cables (for output) into a 1/4" Y to stereo 1/8" jack into the line input of the macbook.
I have the proper input set up in preferences and select Stereo input. When I record It shows two channels recording, but on the meters only the upper one is working. If I switch to mono, it shows 1 channel recording, but BOTH meters are now active.
Am I missing something??

This may be a dumb suggestion, but I have the same set-up, and sometimes when I am getting only half the signal, I just turn the line-in around a bit. That usually does it.
If that doesn't solve it, I would suggest using the RCA out straight to the line-in on the laptop (I assume your mixer has them) instead of the 1/4''-it could be something weird with your adapter.

I have a Sherwood home stereo w/2 audio inputs on the front,Is this an excepted way for hooking an ipod touch to?.Useing a stereo cable of course.

My new stereo has all kinds of inputs to include HDMI. I hooked my ipod touch 4 to the CD player audio inputs on the back
and it was OK w/the vloume at 30%.
When I hooked/pluged my ipod into the LINE IN audio inputs in the front of my stereo I had to raise the volume up to 50%.
I tried my CD player the same way(from headphone jack to LINE IN on the stereo) and I also have to raise the volume.
I'm useing a stereo cable. Thanks

Once again I've answered my own question. If I knew how to delete my question I would.

Importing Stereo File to Two Mono Tracks?

I have a stereo audio file. I'd like to put it into GB2 with one side of the stereo file as one mono track and the second side of the stereo file as a second mono track.
Is there any way to do this?
Thanks,
Leon

Leon, Here is a file explaining what Monomaker does.
Monomaker is a simple mono-merging and stereo-recentering utility plugin.
You can use the mono merge parameter to progressively merge your stereo audio channels into a single mono signal. Turning mono merge all the way up to 1 will make your sound completely mono. Turning mono merge all the way down to 0 will leave your audio unaffected.
You can then recenter your signal using the pan parameter. The panning is equal power (meaning that as you move further over to one channel, sound from the other channel is copied over to the first channel in order to keep the total volume consistent).
Also, in case it's useful, you can re-route the 2 input streams in a variety of ways by using the input selection parameter. "Left-right" means that everything is normal, "right-left" means that the left and right streams are swapped, "left-left" means that you lose the right stream and get the left stream copied to both inputs, and "right-right" means that you lose the left stream and get the right stream copied to both inputs.
Monomaker's signal path is input selection first, then mono merge, then pan.
I have just downloaded it myself and have not looked at it yet. I apologize in advance for not checking it first before posting it. It may or may not help you, and I do not know if it works in Garageband.
Here is the site I got it from

Stereo input on SB

When I send a stereo signal on SB 5. using a Y cable into the input, my computer only receives a mono signal.

Does line-in on the SB Audigy 2 Value card have stereo input? Whenever I've tried to record, I have only been getting the left channel. 2) Where's the game controller / midi input? Do I have to purchase the optical digital i/o 2 add on? And if I do, will this even work with the Audigy 2 value? 3) Does the SPDIF work as a stereo input for any of the devices I've been trying to record from at all? or does it require the I/O device I just mentioned?Thanks in advance,Tyler Pantella
You just can't record analog mono instruments as stereo without a stereo microphone.
If you mean to record a signal which 'stays in the middle' and not 'panned left or right' then you need
- mono to L+R (stereo) convertor adapter
or
- mono to R+L (stereo) cable
between (pre)amplifier output and soundcard input.
<i>Note: Normally instruments are recorded mono --> easier to set instrument positions in final stereo mix</i>.
) yes it is stereo
2) no game/midi on Value. Purchasing Digital I/O won't make any difference to this.
3) dunno, see yoyr user manual

Stereo audio rendering as mono

My husband and I recently purchased a MacBook Pro last November, recently installed Final Cut Pro 5 on it 2 months ago, and now we're experiencing audio problems we've never encountered before.
Fresh new project, new timeline, import a stereo audio file, double click and playing from the viewer it's perfectly fine, but put it on the timeline, shows up on two separate tracks and needs rendering, we render it and it turns into mono. It didn't do this before, we don't know what we changed, it used to work but now it doesn't. We must have changed something but we can't figure out what we did wrong. Even if we separate the stereo track into two mono tracks on the timeline, pan one left and the other right, it remains mono.
Please help, we're completely stumped on this one! Thanks!

The only problem with converting the audio files to 48 is that we have about 200+ audio files, living on about 17 layers, each with their own settings for speed and reverse and eq and more. Going back to reimport all that stuff would kill our deadline by about 40 hours = not possible.
But I did download that utility you suggested, it discarded our prefs, and now everything seems to be better. I'm having to "fool" FCP by placing an EQ filter set for 0 gain (i.e. no change) onto each clip, which trashes the render file, and when it rerenders it's ok, sometimes. For the ones that aren't changing out of mono I go back in and throw away that eq filter and re-render and then it's in stereo. Very strange. Also strange is that some of these animation clips now have 1 frame of black at the tail end before cutting to the next clip - very odd since the original files have NO black at all.
Something very strange happened.

Stereo import problems creates mono to stereo problem/question

After 10 hours of uploading video to the hard drive I'm finally ready to work on the project, but something odd happened. After the first tape upload all the files switched from two track stereo to one track mono.
How does this happen? I don't relish redoing 9 hours of video input and I'm hoping there's #1 a simple way to return it to stereo with out it ever doing this again and #2 are the mono tracks still recorded in stereo and able to be processed into two track stereo.
I've looked around the archives and found little, I'm even having difficulty finding the audio capture settings as I'm working off an FCP book.
In all the years of recording off his camera it's never switched from it's stereo settings so I'm a bit befuddled.
Any help/hope is appreciated.

Do you still have two audio tracks, eg. A1 & A2?
If so, select both tracks and hit Option-L.
This will make two mono tracks a stero pair. You will see two sets of small forward facing triangles to indicate the action is done.

No stereo input in logic8, analog or digit., when not in universal track m.

till now , in logic7 , I didnt work in Unversal track mode. When upgrading to logic8 ,its not possible to create a stereo input, analog or spdif,. When I try to record , I cannot see the waveform in arr. window, but when I stop rec. , the record is done. There is no problem in universal track mode,
but I dont want to change because of my older songs. Is there a solution ?
Message was edited by: ernesto e.

With UTM disabled, only the odd numbered tracks can be made stereo. This is because for a track to be a stereo track with UTM off, it needs the even numbered channel beside it.
If you click on the circle at the bottom of an odd numbered track (1, 3, 5, etc...), making it a stereo track, look at the even numbered track beside it. It no longer exists, because it has now been put to use as the "right" side of the stereo image.
I'm wondering if this is what you are experiencing, and getting confused by...?

Fcp5 stereo to fcp 4 mono

i know this is a pretty obscure issue, but recently i digitized some footage in FCP 5.1 onto an external HD, then opened the scratch clips in FCP 4.5 and upon importing the audio automatically converted from stereo to channel 1 mono (erasing audio channel 2).
has anyone else ever experienced this, or know of a way to preserve the clip's stereo soundtrack?
thanks in advance!

both computers are running the same version of QT, any other ideas?
the raw QT file on the 4.5 computer is in stereo and plays back just as it should in QT, but it changes to mono upon importing. i haven't tried exporting separate audio tracks in linking them in FCP...
Actually, Andy and Leigh are on the right track - this is a QT-related issue.
FCP 5.x (or later) captures dual mono media as two separate sound tracks in the created QT file (do a quick Command-J in QT Pro to observe 2 Sound Tracks). Previous versions of FCP, as you're seeing, expect to see dual mono in a single sound track in QT.
The only workaround that I can remember - and it's been a long time since I've had to do this - was to open the QT files in QT Pro and export using Stereo audio. FCP 4.5 should then see both channels.
Of course, you'll probably have to break the stereo pair in FCP, but at least you'll be able to work with both channels...

How record line-level stereo input on GarageBand iOS?

I'd like to record line-level stereo input sent from my Mackie mixer to GarageBand on my iPhone 4S. I tried plugging a standard 1/8" stereo cable into the headphone jack, but no luck. The GarageBand manual suggests that this is possible, and there is one (pricey) cable I've found that seems to handle this, but it claims that the audio input is mono only, suggesting that I may need a cable connection to the dock (not the headphone jack) to handle stereo. I can't find a cable to do this, however...ideas?
Many thanks,
Jim

Sonoma Wire Works' "GuitarJack Model 2" iOS peripheral can help you do that. It's expensive though.

How do I use the analog input (ADC) to drive a motion profile in MAX

We are trying to use an anolog input signal from a DAQ card to control the motion contol axis. For now, we want the motor speed to follow a sinusoidal voltage waveform, and later on, we will be using a more complex velocity profile.
In order to accomplish this task, we have searched the user forum, and found information suggesting to operate the servo motor in 'slave' mode under the 'gearing' option. Therefore, we have set the Gear Master to 'ADC Channel-1', Mode set to 'absolute', Gear ratio 1:1, and provided the sinusoidal voltage (+/- 5V, 3 Hz) to the AIN1 connector on the MID-7654 controller. When using the 1-D Interacitve 'single axis' control panel, the motor runs at constant speed in one direction only. It does not react to the sinusoidal speed profile request as we expected.
How do we 'turn on' the 'slave' mode in MAX? Please talk us through the necessary steps and settings? Thanks.
Staffan

Staffan,
you can configure and enablethe Gearing mode in MAX and it should be activated after saving the settings and initializing the board. In 1D-Interactive you can't use Gearing. For better flexibility I recommend not using MAX for configuring and enbling Gearing. You better should do this in your application.
In fact there is a perfect LabVIEW-example that ships with the NI-Motion driver (Master Analog Input - Slave Axis Gearing.vi)
I hope this helps,

Can a ComboBox be used for Text Input ?

Hi
In Ms Access the combo box can be used for text input for creating new lines in the Database instead of just being limited to the lines already there in the drop down list. Is this possible with the combo box available in Flex 4. If it is I haven't being successful in getting it to work.
Thanks for you help in advance

I have a macmini on order, I wonder if I can pair the wireless apple keyboard and magic touchpad without using any other input devices, especially, since everything is brand new and not yet paired.

You may just want to save yourself any possible issues
by just hooking up a wired keyboard and mouse on first
start up. Any USB keyboard and mouse should work.
There have been many that have had problems on first boot

Problem about House Number of Vender Transfer by using LSMW+Batch-Input

Hi,
anyone has met the same problem?
by using LSMW+Batch-Input method to transfer vender data the field House Number cannot be added.
Object: 0040 Vendor Master
Method 0002 Shared
Program Name RFBIKR00
Program Type B Batch Input
Thanks in advance!

in Vedndor master LSMW batch input method there is no field for House Number , we have only one filed
(STRAS)for street and house numner in LSMW.
first create the vendors after that update through XK02
for this you can write program small LSMW recording method
using below fileds
LIFNR                          C(010)    Vendor
BUKRS                          C(004)    Company Code
STREET                         C(060)    STREET
HOUSE_NUM1                     C(010)    HOUSE_NUM1
