A: Hi Krebsz,

Thank you for your interest in CrystalSound. We have not specifically tested our product with drone noise, but we are confident that it can filter out any unwanted sounds from your outdoor audio recordings. I just did a quick test with a CrystalSound speaker and a YouTube video of a drone flight, and the noise reduction was perfect. You can try it yourself by downloading our free trial version from our website.

We hope you enjoy using CrystalSound for your drone courses. Please let us know if you have any questions or feedback.

BRs,
CrystalSound Team
