This article covers the following issues:
Keep your Swivl app and FW up to date
Software and firmware versions must be up to date for the seamless robot-mobile device interaction. You can check the most recent changes in our Product Updates
If you notice any audio issues, e.g. static or lack of audio, make sure to check for updates in the first place. See detailed steps here Updating Firmware & Software
Poor audio due to wearing microphone improperly
1. Thread the loop of string at the end of the lanyard through the hole on the corner of the marker (closest to the 3.5 mm jack).
2. Once the loop is fully threaded through, pass the neck or wrist strap through the center of the loop.
3. Pull on the strap to tighten the loop and secure the lanyard to the Marker.
Using your secondary markers
Make sure your secondary markers are only ON when recording specific person and group of people.
Secondary markers DONTs
- do not put it into your pocket
- do not put it behind the book shelf
- do not put your secondary marker too close to other markers
- do not use your secondary marker more than 3 feet from the speaker or group of speakers.
Secondary markers DOs:
- turn on only when it needs to pick up audio from a particular speaker
If you expect to have a long lecture or presentation with a Q&A in the second part, it's best to turn the secondary markers ON specifically during the Q&A. This will ensure the cleanest overall audio in your project as secondary markers will automatically increase sensitivity and pick up all the noise unless nobody speaks into it.
- turn off your secondary markers if you are actively using only the Primary marker
If you have your secondary markers on with no particular speaker, they will be picking up unwelcome background noise. This is expected behaviour so better keep the secondary marker ON when actually using them
- if for any reason you must use secondary markers with no active speaker within 3 feet make sure to adjust your secondary marker gain to the make it maximum.
We cannot guarantee a perfect audio in this case but this should reduce the background noise to the minimum
- generally treat your secondary markers as microphones and ensure they are in the best position for picking up audio.

Ensure your Markers are Paired
When you are recording your video with multiple markers (whether on a C Series or a Gen 2 robot), always check to make sure that all markers are paired to the base. A fully paired Primary Marker will have two solid green LEDs, and a paired Secondary Marker will have a single solid green LED.
Check the capture screen. When markers are turned on (and paired), they'll appear lit up in your marker menu on screen:
Make sure your Primary marker you are wearing is paired as Primary
The best way to check this is simply turn off all the secondary markers and keep only Primary on. After that check the Capture screen - you Primary marker will always be displayed first
Multi-Marker playback in the mobile Swivl app, not on a PC
If you have recorded a video with a C Series with multiple markers and then preview it in the Swivl app, you will only hear the audio from the Primary Marker. This is because the multi-audio track capability is a feature specific to Swivl’s video player on cloud.swivl.com, and is not supported on your mobile device's video player. Once you upload your video to your Swivl Teams account, you will be able to hear all marker audio tracks, and can select to mute or play specific tracks.

Downloading from Swivl
If you choose to export from Swivl and download your video file that was captured with multiple C Series markers, your video file will contain all tracks of audio merged together.
Downloading via iTunes
If you download your video straight from your iOS device to your computer via iTunes, your video file will only contain the primary marker audio track. If you want to have all audio tracks on the video file, you will first need to upload to Swivl from the Swivl app, and then export your video.
