Osmo Pocket 3 audio settings (and fixing sound problems)

The Osmo Pocket 3 has three built-in microphones, one on each non-screen side. Its audio settings are in Pro mode: swipe left from the right edge of the screen, tap PRO, and you can set Channel (stereo or mono), Wind Noise Reduction, Directional Audio and, with an external mic, Gain. For voice, a DJI Mic 2 or Mic Mini transmitter linked straight to the camera over Bluetooth sounds much better than the built-in mics.

Pocket 3 audio sources — Audio options from DJI's Osmo Pocket 3 manual and FAQ. Wind reduction and directional audio only apply to the built-in mics, not external microphones.

Built-in mic settings

Setting	Options	When to use
Channel	Stereo or Mono	Stereo for ambience, mono for a single voice
Wind Noise Reduction	On or Off	On outdoors; built-in mics only
Directional Audio	Front, Front and Back, All	Front for the subject, Front and Back for vlogging, All for ambience
Gain	Adjustable with external mics	Built-in gain is automatic

Notes from DJI:

Directional Audio is set to All when Pro mode is off.
Audio Zoom is on by default: built-in mic volume adjusts as you zoom.
You can't set gain on the built-in mics. It's only adjustable with an external microphone.
These audio settings apply in Video, Low-Light, Slow Motion and Hyperlapse modes.

Using DJI Mic 2 or Mic Mini

The Pocket 3 links to up to two transmitters at once, without the receiver. Swipe down, tap Settings, choose Wireless Mic, then TX1 or TX2, and put the transmitter in Bluetooth linking mode. Full steps are in DJI Mic 2 not connecting to Pocket 3.

Once linked, open Wireless Microphone in settings:

Monitor Volume: sets headphone level if you plug in wired digital headphones.
Low Cut: filters sound below 150 Hz, like traffic rumble and handling noise.
32-Bit Float Recording: the transmitter records its own backup in 32-bit float.
Audio-to-video Sync: the transmitter records a 24-bit mono WAV while the camera records, split every 30 minutes.

If stereo is on and only one transmitter is connected, the Pocket 3 copies that mic to both channels. Use the Mic 2's noise cancelling (press its power button once) for busy places.

Other external mics

DJI Mic (first generation): plug its receiver into the Pocket 3's USB-C port with the adapter.
Third-party USB-C digital mics that support 48 kHz/16-bit.
Built-in Mic Audio Backup: records the built-in mics to a separate WAV while an external mic is in use, useful for ambience. It isn't available in Low-Light at 4K 30/25 fps or 4K/120 slow motion in D-Log M or HLG.

Fixing common sound problems

No sound on playback. Slow-motion videos don't include audio; DJI saves it as a separate file in the same folder. Also check you're not playing on a device that can't decode the file.

How to turn off camera beeps. Swipe down, Settings, Sounds, and lower the volume.

Audio out of sync. If you recorded on the transmitter, line the WAV up with the camera audio in your editor by waveform. Update the Pocket 3 and transmitter firmware; DJI has improved Mic 2 performance in several updates.

Muffled or quiet audio. Don't cover the mics with your fingers or a case. If the transmitter LED pulses red, it's muted. Read DJI Mic sounds muffled.

Wind noise. Turn on Wind Noise Reduction for the built-in mics, or add the Mic 2's windscreen.
