Hi All. I’m fairly new to Audacity. I’m running Audacity 3.5.1 under Windows 10.
I have successfully exported a project to a WAV file specifying Export Range = “Entire Project” and “Multiple Files”. The Project is mono and has signal only in 1 channel–the other channel is silent. Therefore when I export, I want to use the “Custom Mapping” option in order to copy the mono signal to the second channel.
However, when I select Export Range = “Multiple Files”, the “Custom Mapping” option is disabled (greyed out).
a. why is this?
b. is there any way to get around this problem? I want to use custom mapping when I export to multiple files.
First, make your recording a mono recording using the “Tracks → Mix → Mix tracks to mono” (or similar wording in English). This would eliminate unnecessary tracks.
I have never dealt with “Custom mapping”, so I can’t give advice here.
Probably a bug - the multiple file export can split on tracks, and in that mode it’d override any mapping you’d have in the custom mapping. It’s therefore disabled. However, when splitting based on labels, it probably can remain enabled.
b. is there any way to get around this problem?
Before exporting, split the channel to mono:
and delete the track only containing silence. Then, in the exporter, simply export as stereo. Though note that there’s no quality benefit duplicating a mono track into stereo.
I’m not sure what it means to “split the channel to mono”.
Does this mean Audacity sums both channels and places the sum in both channels? If so, I don’t want to do this.
Instead, is there a way to copy one channel to the other? If so, this would work for me because the two channels would be identical and I can export the project as stereo.
–Though note that there’s no quality benefit duplicating a mono track into stereo.
I understand, but when I export to a CD and play the CD, I want the sound to come out of both channels, so I need to have the same mono signal in both channels.
A question about Audacity terminology: does “track” refer to:
a) a selection of the audio (for example, from 15 seconds to 3 minutes and 2 seconds) -or-
b) a channel (for example, left and right in a stereo recording, or the 16 separate tracks of a 16-track tape recorder)
