Recording management
Explore all the features for recording management in the Otii 3 Desktop App.
Start recording
Before starting a new recording, make sure to:
Have an Otii hardware connected and added to the Otii 3 Desktop App.
Select the channel(s) to be measured.
If some of the points mentioned above are missing, the notification center notifies the user that these must be done to start the recording.
To start recording, click the record button at the top left of the Otii 3 Desktop App. Once clicked, it will change to red, informing the recording is active.
If multiple recordings are required, just one after another, click the record button while it is active, and a new recording will start automatically.
Stop recording
To stop recording, click the stop button located right next to the record button.
It is not required to stop the recording to start a new one. Simply start a new recording by clicking the record button while it is active, as described in the previous step.
Recordings menu
Under the RECORDINGS section, found on the left sidebar of the Otii 3 Desktop App, each of the recordings saved is listed separately. By right-clicking on a recording, a menu is displayed, enabling multiple options to further customize or explore the recording, among them:
Rename recording
Right-click on the recording, select the “Rename” option, and assign the new name.
Alternatively, double-click on the recording's name to rename it.
Hide/Show recording
Right-click on the recording and select the "Hide" option. Once hidden, the recording is still shown in the saved recordings but will be hidden from the graphs. To display the graph recording again, right-click on the recording and select the “Show” option.
Alternatively, click on the colored box beside the recording name. Once clicked, the box becomes uncolored, indicating that the graph is hidden. By clicking again, it will be recolored, indicating that the graph is being shown.
Focus/Unfocus recording
This option allows the focus of the graph visualization on a single recording, while the other recordings are grayed out in the background instead of the color assigned to the recordings.
To focus on a specific recording, right-click on the recording and select the "Focus" option. To unfocus it, follow the same instructions but this time, click on the “unfocus” option.
Once the focus option has been enabled on a recording, it can be switched between the different recordings by simply clicking on the desired recording to be focused on.
Delete recording
Right-click on the recording desired to be deleted and select the "Delete" option.
Alternatively, click on the recording desired to be deleted and press the delete key.
Crop recording
By default, the crop option is disabled, as a graph segment must be selected to enable cropping.
On the graph visualization section, select the graph segment to keep by clicking on the starting point, and holding the click until the desired end point for the graph to be cropped. After selecting the graph segment, right-click on the recording desired and select the "Crop" option.
Change color
To change the default color assigned to the recording graph, right-click on the recording and select the "Change color..." option. Once selected, a window with multiple colors to choose open. Choose the desired color, which will automatically apply to the graph. Click the "Close" button to close the window.
Downsample recording
In case of requiring a lower sample rate when analyzing the recordings, it can be modified it by right-clicking on the desired recording and selecting the “Downsample recording...” option. Once selected, a window will open listing all the channels enabled for recording, where one or several at a time can be selected. Define the new sample rate, and to set it, just click the “Downsample” button.
Downsampling removes data points from the measurement and replaces them with average values, so unless you undo the downsample, you cannot increase the sample rate after it.
The sampling rate resolution while recording differs according to the version of Otii hardware in use. For Otii Arc Pro, the sample rate is up to 4ksps and is not adjustable. For Otii Ace Pro, it is adjustable up to 50ksps Note that the sample rate differs depending on the channel,
The sample rate differs depending on the channel. Check the following docs for further info:
Export to CSV
To export recordings as CSV, right-click on the desired recording and click the “Export to CSV...” option. Assign the desired name for the recording, and click “Save.”
