Each session captures a user mic, an assistant mic and four channels from a Zoom field recorder. The four-channel portion is where most of the work lives: each channel needs individual leveling, noise reduction and timing alignment so the mix stays even across the stereo field. You’ll work from a rubric, hand off to QA, and flag recording issues (camera movement during dialogue, sync problems) back to the production team.</div> <div>&nbsp;</div> <div>This is a hands-on editing role. We’re looking for people who can work channel by channel in a DAW, not people who rely on one-click AI cleanup tools.</div> <h2>What you’ll do</h2> <ul> <li>Master roughly one file per 3 hours: clean, denoise, level and align six tracks per session</li> <li>Apply and adjust processing per channel; correct timing offsets between channels</li> <li>Deliver files in the required format and loudness spec through our platform</li> <li>Follow the QA rubric and incorporate feedback from reviewers</li> <li>Note recurring audio problems so the studio team can fix them at the source</li> </ul> <h2>What we’re looking for</h2> <ul> <li>Proficiency in a professional DAW (Reaper, Pro Tools, Adobe Audition, Logic or similar)</li> <li>Experience with multitrack dialogue editing and field recorder audio</li> <li>Strong noise reduction skills (iZotope RX or comparable)</li> <li>Ability to hear and correct timing and phase issues between channels</li> <li>Consistency and speed; you can hit a quality bar repeatedly across dozens of files</li> <li>Availability for full-time hours for at least the next two weeks</li> </ul> <h2>Nice to have</h2> <ul> <li>Background in podcast, film or broadcast post-production</li> <li>Experience working to a rubric or client spec at volume</li> <li>Familiarity with Zoom H-series or F-series recorders</li> </ul>
