Hi Bob,
I've just read through your post and a couple of thoughts sprang to mind. They were ...
ONEChulaivet1966 and Sundance offer some excellent advice that would resolve the issue and is worth considering.
TWOMy take on the issue is that if the banjo records ok in Audacity and not ok in BIAB, then it's not really a mic problem because the audio would be tinny wherever it's recorded since both BIAB and Audacity use the same soundcard process to record.
This got me wondering about mono and stereo. A microphone is mono and if Audacity is recording in mono, it will be heard on both speakers when played back. If, however, BIAB is recording in stereo (BIAB's default) then only one speaker will be heard with the banjo on playback. This could sound "tinny".
To check my theory, try setting BIAB to record in mono and have a listen. To do this, refer to the image below and the instructions that follow it.
- Click on Audio (#1) then select Record Audio (#2).
- Now select Audio Options (#3) from the window that pops up.
- From the next window that pops up, set the Audio track type for THIS song to MONO (#4)
Now record and have a listen to the playback.
Regards,
Noel
