Thanks for the responses Mike. Some comments below.
That said, just keep in mind that this tool only works to convert audio timecode (timecode that has been recorded to an audio track) into metadata timecode that a DAW can read. It will not sync your files automatically; you will still need to plug the files into a DAW like Pro Tools, Reaper, Nuendo to sync the files.
Keep in mind too that timecode is not the same as sync. Timecode (even when recorded as an audio track), just lines up the start of each file. Everything else is still dependent on the recorder's internal clock. This isn't an issue if your takes are only a minute or two long, but over the time of a show (an hour or more), it is likely that the internal clocks in two or more different recorders will drift apart. That will mean that although your files start off in sync, they gradually get out of sync as the show goes on.
I do understand about device drift and timecode, thanks for taking the time to provide that.
However, please take note that the function of the Tentacle devices is for device SYNC, not simply timecode input. For this reason, I don't think your response acknowledges the function of the Tentacle Sync devices/software combination, which is to automatically (via the software application) compensate for device drift and actually sync the sources up in post.
YouTube video's demonstrate how the software automatically compensates for device drift to align all of the input sources so that they're synced regardless of the fact that each device is operating from its own internal clock. (In other words, the Tentacle software indexes off of the Tentacle units for alignment, not the device clocks.)
OK, so the typical application has multiple video cameras (with multiple Tentacle Sync devices) and a single audio source (also with its own Tentacle Sync unit). In post, all of the aud/vid sources are input into Tentacle Sync Studio for automatic syncing.
However, my question is a twist on this same theme...could I use this same technique, using multiple Sync units and TSStudio software to sync multiple AUDIO sources. In my case, there's no video source. (For instance, one recorder located in the audience and the other at the SBD.)
Most of my work is working with timecode capable cameras, so I've actually never had a chance to use the Tentacle Sync software. However, Tentacle Sync does now have a PC-compatible version. It says it supports WAVE files as both input and output formats, so it should work fine to sync up multiple audio files.

Actually, the software you provided a link to is not the PC-analogy of the Tentacle Sync Studio described above. It's called the Tentacle Timecode Tool and is basically just a rudimentary PC-based WAVE file converter that converts waves into broadcast waves. I'm not sure why, but so far Tentacle hasn't offered a PC-based version of their Sync tool. This software doesn't do me much good, at least in terms of file syncing.
So yeah, I'm still trying to determine there is a PC-based analogy of the Tentacle Sync Studio out there yet.
