Split Poly Wav Audio Files in DaVinci Resolve | Multitrack Tutorial

How to split a poly WAV file into individual mono files in DaVinci Resolve. A poly WAV file is what recorders capable of more than two channels (like a Sound Devices MixPre or many cinema cameras) produce, bundling a separate track per microphone/input into one file. Dropping such a file into a Resolve timeline automatically splits it into separate tracks per channel — in this example, a 4-channel file where channels 1 and 2 turn out to be a duplicate stereo mix of two microphones (left = mic 1, right = mic 2), while channels 3 and 4 are the individual mic sources needed for separate editing/processing.

To remove the unwanted stereo-mix tracks: right-click a track and uncheck “Link Clips” so tracks can be selected and deleted individually, then select the unneeded stereo tracks and press delete; right-click and choose “Delete Empty Tracks” to clean up the resulting gaps.

If staying entirely within Resolve, you can just apply effects per track directly. To export the separated tracks as standalone files for use in another app: select the desired tracks, right-click and choose “Export Audio Files,” set Folder Name to Clip Name, enable “Auto-Rename Each Duplicate,” choose Broadcast Wave (BWAV) format (widely compatible), match the project’s sample rate at 24-bit interleaved, choose “Export Individual Clips” so each track becomes its own file, select “Entire Timeline” but limit the export to “Selected Tracks” only, and skip normalization unless needed. The resulting exported files matched the original individual tracks exactly when re-imported to verify. That’s how to split and export a poly WAV file in DaVinci Resolve Fairlight.
