Thanks for all the helpful suggestions guys, really excited to experiment. Reaper looks pretty sweet and I think I'll check that out just to try something new. For the Reaper users, are you using that tool for everything or just the mix process? Meaning will you add fades, convert to 16bit and dither, track out the recording, etc with that tool as well?
I use Reaper for most of the actual "editing" and mixing. Otherwise, my workflow for concert recording now is:
1. Foobar 2000 for seamlessly joining multiple files of a long recording into one long file. (This step is only for long concerts where file sizes are over 2GB).
2. Izotope RX:
- Declick module for knocking back applause levels
- Global gain adjustment (if needed)
- Denoise (if needed)
- Render new file
3. Reaper:
- Drop markers, track splits, fades
- Mix multichannel projects
- Render tracks from project region selections (FLAC; same resolution as original recording).
4. Reaper or Foobar:
- Render MP3s for sharing / posting. If I'm still in Reaper I'll do this from the project the same way as the FLAC files. If that's not convenient, I import all of the FLACs into Foobar and convert in bulk there (which is SO much faster).
On the rare occasions I'm making CDs, I'll take my 24-bit FLACs back into RX and dither / downsample / decimate there. Lately I use Foobar with the Sox resampler to do this instead, I can't hear any difference in quality. Usually I only keep the 24-bit FLAC files around, along with the original files.
