Keeping the WAV file mono


I’m using Audacity 2.1.0, on Windows 7. My microphone is the ATR2100-USB. I am trying to record WAV, mono, sample rate 44.1 kHz, 16 bits in Audacity and upload to I am recording on mono, but when I go to export the file (I was saving to My Music folder in Windows 7) I get a box informing me that the file will automatically be mixed back to a stereo format. That must be the default setting, but I don’t know how to change it so that the file stays in mono when I upload it to voicebunny. If the uploaded file is not WAV, mono, sample rate 44.1 kHz, 16 bits, voicebunny automatically rejects it and my audition is not received. Can you advise me how to use my system to keep the file from automatically mixing to stereo so I can then deliver it in the mono format that voicebunny needs?


Make sure all your tracks are panned centrally (the L…R slider should show “Pan: Center” when you click on on the slider handle).


If it’s just a recording of your voice only, (e.g. no backing music on another track ), then selecting " 1 channel (mono)" in Audacity preferences may give you what you are looking for …

You can change the “Quality” to 16-bit in Audacity preferences, from the default setting of 32-bit.

On any tracks you’ve already recorded which are “dual mono” , ( i.e. looks like stereo, but are two identical mono tracks), use “split stereo to mono” , which separates them into two mono tracks, then delete one of those tracks by clicking on the “x” on the top left corner. Then save as 16-bit WAV format …
