2024.4.0 (08/27/2024)
What’s New
Major Updates
Removed the SSF/Device Plugin requirement from Live Capture mode and File Import for a more efficient, easier to understand workflow and a lower barrier to entry for getting started with the Data Studio
After selecting Next the user can start collecting data right away. The Data Studio will automatically pull the proper configuration properties (Sample Rate/Sensor Names) from the device firmware when it connects to the device. Previously, the Data Studio required the user to select or create an SSF file/Device Plugin to load these properties.
The ‘Device Plugin’ can still be selected from the Select Connection Protocol screen. Device Plugin is the old method of connecting to devices from capture mode and can still be used for any projects that were previously set up to use it, or for connecting to any of the custom/MQTT-SN specific devices that require custom connection settings.
The ‘Import Files’ workflow has also been overhauled to include a similar paradigm. When you import external files into the Data Studio you only need to enter the ‘Sample Rate’ used in the files. Previous to this update the user was required to select or create a Device Plugin
Updated the Data Studio to auto-create a metadata property for Sample Rate. The sample rate property is automatically saved when the user does live data collection or imports external files.
The Project Explorer has been updated to remove ‘Sensor Configuration’ options in files and replaced with the new Sample Rate metadata option. Previous to this release in order to update Sample Rate on a file the user was required to create a Device Plugin and select the sample rate. The user can now edit the sample rate directly by clicking Metadata → Edit.
The Project Explorer ‘Time’ column has been updated to use the Sample Rate metadata in the calculation instead of the Device Plugin sample rate. Any projects that previously had a Device Plugin will automatically be converted to create the Sample Rate metadata from the Device Plugin.
Minor updates
Added ‘Import From Python’ option to the File → Import Model main menu options
Added validation for preventing sensor trim start/end location to be length 1
Bug Fixes
Fixed issue where video ‘server status’ could sometimes get out of sync and not download videos automatically
Minor stability improvements
2024.3.0 (07/16/2024)
What’s New
Added ‘Text to Speech and AI Voice Generator’ feature. This combines ElevenLabs voice generator API with the Data Studio labeling capabilities to generate speech audio datasets based on text prompts. (Note: Requires an ElevenLabs account to use)
Text to Speech and AI Voice Generator can be found in the left navigation bar
Generated files can be automatically labeled with segments for Prompt, Gender, Accent, Age, Description, Use Case, or Custom Text
Generated files can be named/generated with metadata options saved to the Project Explorer
The Data Studio will auto-generate metadata and labels based on your file settings
2024.2.1 (07/01/2024)

What’s New
Segment Explorer Improvements - Updated the segment explorer control to make it more efficient/easy to view your labeled data and update your label data in project datasets
Multi-Segment View - The segment explorer control now shows all segments in your file instead of just the selected segment in the graph. This gives much more insight to what events are happening in the file and enables much faster labeling methods. You can use the keyboard shortcuts (Ctrl + Click) and (Shift + Click) to select, edit, and delete multiple segment labels at a time
Added New Columns - New columns have been added to the segment explorer control (Length, Time, Status, Uploaded, Last Modified, UUID). Note: Hide/show columns by right-clicking on the segment headers
Length
Total number of samples in segment
Time
Total segment time length (Hours / Minutes / Seconds) based on file sample rate
Status
Server sync status (Synced with server / Saved offline / Has pending changes to be saved)
Uploaded
Date/time segment was uploaded to the server
Last Modified
Date/time segment was last modified on the server
UUID
Server unique identifier for the segment
Column Sort Feature – Added the ability to sort segment data by clicking on the column header. This is useful for finding outliers in segment data
Segment Filters – Added the ability to filter segments in the segment explorer by event. This can be used by clicking (+ Filters) at the top of the segment explorer
Multi-Segment Selection - Added the ability to select multiple segments in the graph view by either holding (Ctrl + Click) or (Shift + Click) while selected segments. Selecting segments in the graph will highlight the associated segment labels in the segment control view
Status Column - The segment status column has been updated to tell more information about your segment server status. It has three states (Green - Synced with server, Gray - Saved offline, Edit Icon - Has pending changes to be saved)
Copy - Added the ability to copy a list of selected segments into another session. (Right + Click)
Copy UUID - Added the ability to copy a list of selected Segment UUIDs to your clipboard. (Right + Click) Segment UUIDs are unique identifiers used by the server and can be used as parameters for functions in the SensiML Python SDK
Segments Outside of Trim Area - If you have trimmed the ends of a file and there are segments outside of the trim area they will now show as gray in the segment explorer
Keyboard Shortcuts – New keyboard shortcuts have been added to make labeling data easier. Some old keyboard shortcuts have been updated. You can find the full list of DCL keyboard shortcuts under the menu option Help → Keyboard Shortcuts

Added sample rates 210hz, 400hz, and 600hz to QuickFeather data collection options.

This means setting a sample rate of 400Hz can result in captured sensor data varying from board to board within a range of 360Hz – 440hz. This sensor limitation should be understood and factored in your models for applications where sample timing sensitivity is critical.
