Hey Gang,

I shot some video with an external mic and did not know I was recording in mono...  It is done now, how can I improve it?  I know the key is proper capture in the first place...

I have isolated the audio from the video and saved it as its own file.  In Sound Editor, I open the file and it looks like the Left has all of the sound.  No, it will not be true stereo, but how can I copy the Left channel and paste it on the right channel?

Thanks for the help.

Pretty easy.  There are a lot of mono cameras out there so they took care of us !

Okay, Thanks.  I did not even realize that was there.  I click on the mono to stereo button, but nothing seems to happen.  It is almost like the program sees a right track, but there is nothing on it.  


So, after playing with it, here is what I did...    I went to the Mix Editor and cut the left track and pasted it on the right track.  It seems to work for now.  


My mic person was doing who knows what and there is a lot of "rubbing" noise from him holding the mic.  Anyone know of a good way to trim the mic noise as much as possible?

Help....

When you clicked on that command, did a pop up window open and give you some options?  Play with the slider.  You should hear a difference with the by-pass checked or unchecked.   I'm sorry bbut I don't have any mono files to play with to give you more information.

I found a mono audio file and I apologize for the wrong information.  Try the "stereo enhancer" effect with and without the mono to stereo.

I'm getting forgetful in my old age.  

Jess, where were you earlier.  I'm sure you would have given the right advice !

Steve: Just got back from Washington DC from chaperoning a school choir/orchestra group to a music festival competition. The choir/orchestra won top honors in all categories they participated in.

I never noticed that Sound Effect option till now.

kirkifer: Another way to copy a channel from left to right (or vice-versa):

1) Extract the audio from the video
2) Open the extracted audio in Sound Editor
3) To apply one audio channel to both channels, in your case choose "Left on both" for channel control in the Input section of the Clip Properties dialog box.
4) Save the modified audio by using Export Track/Clip and save as wav file
5) Open the video file in Videowave
6) Mute the native audio of the video
7) Bring in the modified video (from step 4) and put to music track
8) Preview the video to ensure video and audio are in sync
9) You can use Output As to create a new video in mpeg format (or any other format presented in the option)

actually you can NOT make an Actual Stereo Recording from a MONO track.  You can do something like what COMMAND RECORDS did in the late 50s and even though it isn't really STEREO it still sounds SUPER, depending on your talent the your patience.


Mono means that BOTH the Right and the Left tracks are combined on ONE source or that they were NEVER seperated to begin with IE a ONE mic on a camera etc.

  So once you have the MONO track on the PC, you will need to get a duplicate  Left and right track, if you already are there fine, if not get a RCA Y-Adapter and when you record from the camera to the PC plug the ONE camera OUTPUT into the Y and then the Y into the Left and right RCA inputs on the PC. NOW you have a left and right track showing, they are identical to each other but so far you have two tracks. You can also follow the above instructions from the the other poster if you can duplicate the the track to the other, great. Once done is where I will try and help you to have some fun.  You will not notice anything about them in playback because two stereo speakers playing identical tracks will sound like two stereo speakers playing a mono track. same results.

  Using SOUND EDITOR you can load the WAV file and you will see the ability to use an EQ and you can use this EQ differently for each track but must be saved in between.

  So first if you want the Lead Vocals to be more pronunced on the LEFT track, then select ONLY the LEFT track and adjust until the LEAD vocals are at the clariity you want and lower the levels at the higer and lower freqs. NOW save it as TEST1 and load test1 back into SOUND EDITOR, now adjust the Right track until the lead vocals are weaker in levels and the other freqs are increased. save again as test 2. Now with either track you can add amplification or bass boost, but DO NOT do it to both tracks, pick one and and not the other and now save again.

Now play back the finished product and you should hear a slight change and some depth. Some EQs will allow you you reverse polarity and add different effects such as echo etc. So have fun and experiment, but remember ONE thing, you will not hear any difference in the left or the right speaker unless you have a difference in the source.

If you have the patience you can really make a MONO track sound super and have a STEREO EFFECT in playback. You can filter, clean it, amplify it, boost the bass but always be careful that you do not boost to the point thta end up with the unrepairable CLIPPING. So work with it at lower levels first, when you have EQ'd and added the effects you wanted, then SAVE it and with another copy of the file, play with the bass boost and the Amplification. You can edit a single word out as well, but will need to increase the zoom on the sound wave to see the click or the pop or whatever that you want to edit out. It is really a lot of fun once you get the feel for it and the results are great.

I'm sure that if Kirkifer ever comes back, he would be happy to read what you posted.  The editing program in Sound Editor is not designed to be a full service audio editing program.  Sound Soap (included with EMC 9 Deluxe),  Dart and GoldWave are much better choices if a lot of editing must be done.
