I recorded audio on a zoom h4n and all sound was recorded on the left channel, the right channel is silent.

I am using AUDITION CS6 and am trying to get the sound on both the left and right channels. It won't allow me to convert to stereo because the file already is in stereo. I can convert to mono, but I get diluted sound (it combines all of the left channel, which has sound, and all of the right channel with has no sound, and the result is watered down mix). If I try converting to 5.1 surround,then I get sound for the left channel but no sound anywhere else. There's gotta be an easier way to tackle this.

Any Suggestions?

Jim

Effects > Amplitude and Compression > Channel Mixer. On the Left tab, keep as-is, on the Right tab mix 100% Left and 0% right. Apply the effect and it will clone the left channel.

Alternate: Right click file in bin, extract to mono and delete the empty mono file.

Thank you, that worked perfectly. I even customized a setting so that I can get the right mix every time by clicking just one button.

Is there any way to perform this process on multiple audio clips at once?

I might have 20 or more audio clips for every scene of my movie and doing this process one clip at a time can be a bit cumbersome.

Record a "favorite" and save it. This is like a photoshop action where it records applied effects and their settings.

Go to Edit > Batch Process, drag files in and you can batch apply a preset and keep the files as-is in your project to be used or saved as needed, or you can export them as a second set of processed files.

Remember, you can export your audio to separated mono tracks easily. Then use the file for the left on both sides. To convert to stereo with distance modulation, you can do it with some busses and the right delays. Most of our directional sense comes from the timing of reflections. But there is also timing in between frequency distribution. Think about a stage during a concert. Drums are at the back to allow the front audience some of the feel of their sound (low frequencies have a long wavelength and need that distance before we actually hear them rather than feel them). To create the distance of room or widening of the sound, the first step is a bus that catches the sound in mono, gets a slight low rise and extreme high fall, to bring in the lows. Delay this by close to 38ms (no more than 50) until your playback feels just a little too punchy, almost vibrating. Now apply a high pass to the right and left normal tracks (removing the punchiness). Your mix will feel a little less powerful at first, just boost your lows slightly (3db max) and swap phase to cut out the common frequencies (the distance between lows and highs will grow, enhancing the dynamics a bit). Now add another mono bus and feed a track into it. Do a high pass and delay it by 30-50ms. Do this up to 3 times, varying the delay by adding 15 10 5 to the ms on the delay and dropping by 6db 10db 15db respectively. This is an analogue style reverb that actually helps enhance the recognition of the frequency spread. You can then get a better understanding of any noise level, and cut that out too. By adding delays, you're really just faking a bounce of the highs. If you want some low reverb, add a delay at about 100ms on another bus and drop it by 5-12 db (6 is usually a good bet for a short back to front with few people in the room, but drop by more with longer rooms). Pan all mono tracks to center. Now apply a delay to the right side track of about 40-45ms. This will offset the left from the right. Now apply a slight panning of the early lows delay bus one side or the other, which will offset it even more, allowing a more dynamic feel to the sound. IF there is a visual, you won't be able to tell the difference between real sound and this mix. If no visual, it will be weighted slightly right, but amp'd slightly left if you pointed the reverb that way. Point all of the tracks listed above to a stereo bus, and amp each side until they are within 3db, which is an almost mono distribution (a central balance).

Also, In light of recent problems found with audition, consider the following:
Make a Batch file in windows that will
1. take a dropped file as input(your session file will do)
2. get the parent folder (the whole structure is important)--this is the folder where your session is, along with the folder containing your audio files that you record.
3. periodically non-destructively (as in not deleting files that are no longer in the first folder) Mirror the contents of the parent folder to another location anywhere on any drive (every 2-5 minutes works) and make sure you set this folder, or you can simply use the parent folder of the original file and add a Backup folder inside,
4. then just continually make backups using a forever loop (Condition is always true like While 1==1). You can close it when you close audition by simply closing the Command prompt window. You won't lose everything even if you crash, after all, audition cannot delete what it knows nothing about.

On mac open automator:
start by making an application--call it BackupStart. create 2 Path variables: SessionFile, ParentFolder. These will be what you use to grab your files. Create more Path variables with names similar to BackupFolder#, where # is the number of which backup folder. You can now Set Variable Value (in actions library) for the path Session file as your first action (this will catch the path of the file you drop on the app). Next, run a shell script in Bash (an action in utilities or system), and set STDIN to Arguments. Clear everything in the shell, and type: dirname "$1" Exactly as shown (don't replace dirname, it's a command that grabs the name of the parent folder of the file you just dropped in. Add another Set Variable action for ParentFolder. Now use an ASK for finder items action, and look in it's options to "Ignore this items input" and check the box. Add a Set Variable for BackupFolder1. Repeat for each BackupFolder variable you have (ask for folder, set variable). Now add a GET VARIABLE action, go to options and select "Ignore input" again, make sure you are GETting the ParentFolder variable. Now another GET Variable for Backupfolder1, but DONT ignore input (you want the two to pass into one another and continue on). Repeat this last op for each BackupFolder variable, leaving the ignore input unchecked to group them all together. Now add a RUN WORKFLOW action and turn off "Wait for workflow to finish". Save this file, leave it open, and go to file Duplicate. Rename the duplicate BackupLoop1. File >Convert this doc to a Workflow. Delete the variable SessionFile from this document and all but the very last of the actions(Run Workflow). The other variables are still necessary. Everything we add should be above the RUN WorkFlow action. Use a Get Variable on your ParentFolder, and as before, do not check ignore input. You need this to run straight through from the first document. Add the GET Variable for your backups. Add a Shell Script in Bash, with STDIN set to Arguments. Clear the script box, and type:
rsync -vau "$1/" "$2/" (enter)
rsync -vau "$2/" "$3/" (enter)
The first line copies your parent folder's contents, the second copies the first backup to the second. You can continue this until you have handled every backup in the script. Apply a PAUSE action for a few seconds. Now add a Loop Action, and set it to run 50 or more times (applies a wait time until finish) and set it to use the same input. This will continually backup all your data as you record, and when you hit stop, you should get a copy of your audio almost immediately after, done by your system, and making the RAW file data into a finished file set. Now add the GET VARIABLE set again for all your variables, ignoring the input of the first one, but keeping it for the others. Point them into the last action of RUN WorkFlow. Again, Duplicate the document, call it BackupLoop2. Change the Run Workflow in this file so it points to where you saved BackupLoop1. Change the RUN WorkFlow in BackupLoop1 to point to BackupLoop2. Change the Run Workflow in BackupStart to point to BackupLoop1 and place BackupStart in your DOCK. When you get ready to record, drop the session file onto your dock icon, pick your backup folder(s), and then let it go. Hit record, and when you hit stop, wait a few seconds for it to end the raw file tags. Now check your backup folder. You should have a perfect WAV capture there.

IF audition crashes, you can drag the files in your backup folder to the original place and continue.
