Audio - mono and stereo

Hi, I captured the sound for my video using a single boom mic plugged in which recorded to one channel. On import, there are two audio channels and linked as stereo. One of these has no audio (no waveform), the other has the audio.
In the current setting, when I playback, the audio comes from only one speaker - this is the one to which the channel with the audio is directed.
So do I set the pan to 0 and have the audio sent to both speakers OR delete the empty audio track, duplicate the other one and then link as stereo?
Whats the best way to do this?
thanks

So do I set the pan to 0 and have the audio sent to both speakers OR delete the empty audio track
Both. Convert the clip to two mono channels (Option l [lowercase L]), then delete the empty channel. Next change the pan on the remaining clip to 0 (center).

2 mono and stereo

I have clips imported that say 2 mono and stereo. What is the difference? Why did some come in 2 mono and others stereo when they were all shot on same cam same settings? Interesting the 2 mono wave forms are to distinc channels which tells they too are stereo.
Thanks!

When you captured, are you certain you had the audio capture settings the same for all clips? You can set it for Stereo, Ch 1 + Ch 2, Ch 1, Ch 2 or a Mono Mix.
And just because the waveforms look different on a pair of mono tracks, it doesn't automatically mean they're stereo. It could be just two distinct mono tracks from two sources, even if they were recorded at the same time.
You can easily change two mono tracks into a stereo pair by highlighting the clip in the Timeline, then go to Modify>Stereo Pair (Option l).

Random switching between mono and stereo sound on t400s

i just found out one problem on my t400s, it randomly alters between mono and stereo sounds. any idea why that happens? i'm using win7 enterprise x64, with all the latest drivers installed (i.e. no beta drivers).
T400s - 2815RW1 + Win7 Ultimate
Don't pm me for help! That's what the forum is for. Also, Google's nicer than me. Ask him.

This issue seems to be similar to the "T410 Extremely Annoying Audio Issues" thread, have you tried potential solutions there? (Can't summarize it because I haven't read the thread.)

Change between mono- and stereo-sound

My question is if there is any way to change between mono and stereo sound on the ipod nano 3th generation...?
Thanks for help!

Are you not getting stereo? What are you listening with - maybe there's a plug problem...
Does it sound like stereo from iTunes?

Difference Between Mono And Stereo ?

I want to know whats the difference between mono and stereo when you create a new track ? I'm new here ..

Mono is for recording monophonic sources (one microphone). Stereo is for recording stereophonic sources (two microphones).

IMac Mono and Stereo

I am transfering my vinyl to my iMac via USB lead using EZ Audio Converter by Mixmeister. However when it records it records in Mono and not Stereo, can anyone help please?

Mine not only records in mono, there is alot of static. I tried it on my daughters PC and it recorded fine. If anyone knows how to get rid of the static and record in sterio from the EZ Audio Converter please let me know. I even tried recording directly into Garage Band and get the same static and mono.

Mono and stereo audio output

I had to do a recovery on my HP Pavilion A6603w. I set up my HP supplied RealTek HD Audio manager for a four speaker system, as before and did the Realtek tests which went fine. It sounds great just as before the recovery when I am playing stereo music. The odd thing is, when I am listening to something over the web which isn't stereo, or anything generated by the computer in mono, it now only comes out of the front speakers (located in the monitor) whereas before the recovery, even mono came out of all four speakers. Is this really how the machine is supposed to work or is there a way to make mono audio come out of all four speakers?

The key here is telling "Windows" that you are have a 5.1 speaker setup. If you are getting 5.1 sound from your DVD software player or games, etc... but Windows sounds are only coming from the front two speakers, then you have to Windows that you want to use 5.1. For the encorporated Realtek driver, you should be able to select the Speakers icon in Sound Properties and then click the configuration button to get to a Speaker setup screen.
To get the Configure button to be active, the speakers icon has to be selected (in blue) - not just set to default.
What you are talking about is the Realtek HD Sound Manager software. You should leave all the speaker selections checked on the left. But these settings are treated as separate and enable sound throughput at a lower (?) level. The Vista configuration setting simply tells Windows to send Windows Audio through 5.1 channels instead of stereo (default).

Please post rather than send me a Message. It's good for the community and I might not be able to get back quickly. - Thank you.

NEED HELP!! outputs mono and stereo

Im new to Logic but not pro audio. I have a Motu 896hd and It has 22 outputs. Logic will not show a selection for individual outputs in mono. Just Stereo Pairs 1-2 3-4 etc to 21- 22. I need to see all the Channels to route properly to outboard gear Please help. Looked in Manual Doesnt say much about output assignments

[..] for individual outputs in mono. Just
Stereo Pairs 1-2 3-4 etc to 21- 22. I need
to
see all the Channels to route properly [..]
AFAIK you can't do that for the output, only for the
input (try switching a channel in the environment to
mono).
But if you're just working with outboard gear, you
might want to have a look at the I/O plugin under
"Logic -> Helper". Using this plugin is more
Logic-like than wasting the input or output tab for
insert routing.

Thanks Guy A real life saver....
I use an external mixer 32 channel and need to route audio indiviually was a real downer when I got nothing but Stereo tracks.

I did a "Bounce - replace all tracks" and now all my mono audio tracks are stereo... What's the safest way to get them mono?

I don't think I unchecked the "Include volume and pan automation" checkbox before the "Bounce - replace all tracks" conversion. I hadn't added any volume or pan automations I figured: you can't include something I haven't added, although I did probably have the pan controls set in the mixer. Anyway, now I want to convert my six (previously mono) tracks from stereo back to mono, preserving as much as possible the original mono sound quality before it was converted to stereo, so that I can start mixing. Every MP3 I've exported is ignoring the pan settings I have in the mixer, I suspect due to the fact that the audio for each track is now stereo (I changed the tracks back to "mono" in the mixer but the audio remains in stereo). Unfortunately I don't have any unused audio files in the audio bin and I killed the undo history as well.

Thats what I came up with:
As you can see I got a stereo file on track 1 to start with,
Now go to the corresponding channel strip and switch to mono,
Perform a BIP to a new track
and the result will be in mono.

Audio - mono/stereo

Pretty new to FinalCut.
I have imported and created a Media map with clips in it.
Clips "item property" says its stereo.
Same thing after pulling a clip into the wiever. Still stereo.
From there on to the timeline or canvas it
changes to mono?
And I've read the manual
and I really can't seem
to find the solutions to this.
Tried to seach in prefs. but there seem
not to be the possibility of either mono
or stereo when you define how many
audio tracks the project should consist
of.
Hope someone of you guys can help.
Best regards
Torben, Denmark

Sounds like one audio track ?
Any track in FCE will be mono in effect, to have stereo you require a Stereo Pair, two separate tracks working as one.
You will notice small green inward facing triangles in a stereo pair edited to the timeline.
Use Modify>Stereo Pair to create a stereo pair or make them separate.
If you require one track to be heard on both speakers: open the audio into the Viewer and move the Pan control slider to centre it or type 0 into the Pan field.

FCPX ignores audio mono/stereo

Here's a new problem! (sigh)
Working on a show with several multi cam clips, all are specified dual mono (parent clips, multi cam clips in the bin, clips on the timeline, etc all dual mono) but my final export ("Master File" preset) is obviously stereo. On the timeline FCPX occasionally plays back in stereo (I can see it in the meters) but the problem seems to be corrected when I "expand audio components" and then collapse them... But the fix doesn't stay fixed for long.
Any Idea what could be going on??

When i export a audio mono channel it turns into stereo

hello
something went wrong somewhere along the way, now every time i export an audio channel it forms as a stereo channel.
by the way, how can i split a stereo channel on logic 9 into two seperate mono's?

Hi,
1st: There's a little circle below the channelstrip's level meter indication mono or stereo. If it's a single circle, it's mono. If it's a double circle, it's stereo. You'll also see the level meter single or double. Look for the single or double level meter!!
2nd: Be sure you've created a mono audio track. If the track yo try to export is stereo (look at the level meters if they are doubled or not!), the resulting audio file will be stereo. That's because the export function puts the audio data through the circuitry of the track's channelstrip. If you put any Audio file, be it stereo or mono, into a mono track, the resulting export file will be mono. If you put any Audio file, mono or stereo, into a stereo track, the export's result will be stereo.
Experiment - there seem so be a little inconsistency when or when not logic switches a track from mono to stereo and back!
3rd: If you want to avoid the channelstrip alltogether, use the sample editor or the bin to convert the stereo file into split files (one for L, one for R)

HT4589 How do I change the audio to dual mono from stereo when using Share to DVD in Final Cut 10.1?

How do I switch the audio to Dual Mono from Stereo when using Share in Final Cut Pro 10.1? Even though the audio is all in dual mono in the timeline, it lists it as stereo in the share box.

Hi rationale1,
Welcome to the Support Communities!
The share to DVD settings in Final Cut Pro X use the Dolby Digital settings which are stereo for DVDs. So this can’t be done directly in Final Cut Pro X.
The link below will explain the Dolby Digital parameters and options in Compressor 4. You may need to research a different DVD authoring software to achieve your desired result.
Dolby Digital - Compressor 4 User Manual
http://help.apple.com/compressor/mac/4.1/#cpsrb71736a2
Dolby Digital
The built-in Dolby Digital settings (in the Create Blu-ray and Create DVD destinations, as well as the built-in AC-3 and EC-3 audio settings) use the Dolby Digital transcoding format. This format encodes Dolby Digital (AC-3) and Dolby Digital Plus (EC-3) audio files that contain multiple audio channels, including 5.1 surround sound. You can also create custom settings that use the Dolby Digital transcoding format.
Note: All files intended for video and audio DVD authoring must have a 48 kHz sample rate as required by the DVD specification.
DVD Video: Choose this option if you’re encoding for use in a DVD video authoring application.
DVD Audio: Choose this option if you’re encoding for use in a DVD audio authoring application.
Tip: For stereo encoding, rates of 192 kbps and 224 kbps are typical and will produce good results. For Dolby Digital 5.1 encoding, a rate of 384 kbps is recommended. For 5.1 Dolby Digital Plus encoding, a rate of 192 kbps is recommended.
Cheers,
Judy

Mono to stereo or combine audio

I have an iMovie that is an electronic white board. I recorded an audio file from my Nikon (so I would think it would be stereo) and added that to the whiteboard video. I've been told the audio is mono, but I don't know how to verify that or how to correct it. 1. How can I tell if the audio track is mono or stereo? 2. If it is mono can I convert it to stereo or play it as mono on both tracks to simulate stereo? Thanks.

Hi
In iMovie You can not do any of it.
But You can
• From Event's - iPhoto Videos take it and drop it into a new Project
• From Project You export it as QuickTime and as Audio only (.aiff)
• This file You can open in an Audio/Sound-Editor as Audacity (free on Internet) or GarageBand ( might work ? )
And here in e.g. Audacity You can see if the Right and Left track are identical = MONO or have slight differences. I do this by invert one track and add it to the other - if it is silent - then the tracks are in Mono if not then You've got a Stereo Sound from start.
Mono to Stereo = Impossibly
Mono out via Left and Right speaker - Just copy the audio in one track and paste it into the other - BUT still when You listen all will come from center. Simulated Stereo - I've never seen any working application that can produce this.
When done in Audacity - then Save (still as .aiff) and import this to Your Movie project.
Far from so easy as in FinalCut Pro. Where You just pan audio to the other canal.
Yours Bengt W

Mono audio tracks to stereo

I cannot get my mono clips to become stereo. I tried highlighting both audio tracks (one, is imported music/ two, is imported b roll audio) and doing option -L and it does not work. Cannot even get the stereo pair in the modify pull down to highlight.

I've noticed that since I've upgraded from FCP 4.5 to FCP 5, I can no longer change the audio track config of an offline clip in the browser. I used to be able to ctrl-click in the Audio column, and it would bring up a submenu where I could change from A1+A2 to Stereo.
Now there is no such option. Am I doing something wrong?
