Topic: Swapping channels?

[BradM]

I recorded a show tonight, and realized about three minutes into the first set that I had the left mic plugged into the right channel and vice versa; I let it run that way for the set, and switched them for the 2nd and 3rd sets. Is there an easy way to take the WAV file (that'll come off my Nomad JB3) from the first set and swap the channels? There was no PA, and the mics were about 12' from the band (acoustic drums, two horns, and keys through an amp), so I got some really good stereo separation/placement that I'd like to come through correctly on the CDs.

Can Audacity do this easily? If not, is there some other piece of software that will?

Any info would be appreciated. Thanks!

Aloha,
Brad

it's very simple in wavelab.  select all...then edit > swap channels.  audacity must have a similar function.  good luck!

In Audacity:

• import / open the stereo WAV file
• using the upside down black triangle dropdown next to the filename, select Split Stereo Track
  
• in the Left track, select Right Track from the same dropdown
  
• in the Right track, select Left Track from the same dropdown
  
• from the main menu select Export As WAV
  
  

This assumes you have your Preferences and Project settings defined properly for outputting the same bit-depth / sample rate as the original file.  For example, if you have a 16-bit / 44.1 kHz recording, ensure the following are set:

• Preferences | Quality | Default Sample Format = 16-bit
  
• Preferences | Quality | High-quality Dither = None
  
• Preferences | File Format | Uncompressed File Format = WAV (Microsoft 16-bit PCM)
  
• Project Rate (bottom left corner of window) = 44100
  
  

Note:  if the original file is 24-bit, setting Preferences | Quality | Default Sample Format = 24-bit is insufficient - you need to define the Sample Format within the project itself by selecting from the dropdown: Set Sample Format = 24-bit.  For example, if the original file is 24-bit / 48 kHz, set the following:

• Preferences | Quality | Default Sample Format = 24-bit
  
• Preferences | Quality | High-quality Dither = None
  
• Preferences | File Format | Uncompressed File Format = Other | Header = WAV (Microsoft) and Encoding = Signed 24-bit PCM
  
• Project Rate (bottom left corner of window) = 48000
• using the upside down black triangle dropdown next to the filename, select Set Sample Format = 24-bit

Thanks, guys,that's just what I was looking for. I need to clear some space on the hard drive, and will give it a try this weekend.
