Streamlining Mobility Development Reviews: Sound One Ver.17 Released

Sound One, a member of the Ono Sokki Group (Headquarters: Yokohama, Kanagawa; President: Isao Kasai), has released the web application "Sound One Ver.17."

In this update, OBD2 data recorded via the smartphone app "Sound One Recorder" can now be viewed alongside audio, video, and driving trajectories within the web app. Users can check irregular noises or anomalies during driving against the same timeline as engine RPM, throttle opening, and other vehicle data, allowing for smoother phenomenon identification and cause isolation.

Sound One has previously provided an environment where sound, video, and GPS logs recorded on smartphones could be uploaded to the cloud and shared/analyzed via a web browser. With Sound One Recorder Ver.6, the app became compatible with Bluetooth-connected OBD2 adapters, enabling the recording of vehicle data during driving. Ver.17 leverages this recorded data within the web app, further strengthening the workflow from "recording on-site" to "sharing/analyzing in the cloud."

For driving evaluation and noise investigation, it is crucial to confirm "what was happening in the vehicle at the moment the sound changed." For instance, identifying the cause of humming during acceleration, noise during deceleration, creaking while turning, or road noise due to surface changes can be difficult based on sound alone. With Sound One Ver.17, confirming OBD2 data alongside video, sound, and GPS traces provides a concrete understanding of the vehicle's condition at the time of the event.

This enables various stakeholders involved in mobility development and evaluation—such as automotive, parts, and aftermarket manufacturers—to review NVH evaluation, quality checks, and cause analysis while viewing sound, video, and vehicle data as a single information set. It eliminates the burden of managing video, audio, and vehicle data separately and manually matching them later, thereby streamlining the process from review to sharing and countermeasures.

Enhanced CSV output and seamless external analysis deployment
Sound One Ver.17 extends the existing CSV output function. In addition to GPS and acceleration data, vehicle information from OBD2 can now be exported as a CSV file.

After reviewing the data in the web app, users can easily deploy CSV files to internal analysis tools, spreadsheet software, or external evaluation environments. It serves as a bridge between on-site cloud review and more detailed, professional analysis.

Furthermore, a feature has been added to extract audio from data recorded with Sound One Recorder and download it as a WAV file. If calibration values are set during recording, the app can output 32-bit float WAV files with absolute sound pressure (Pa) reflected, facilitating detailed analysis using external acoustic analysis software.

Expanded display area with new sidebar layout
The entire screen layout of the web application has been overhauled. Ver.17 features a sidebar layout, rethinking the header configuration, which allows for more effective use of screen space on widescreen displays and laptops.

This makes it easier to browse file lists in 'Drive' and view waveforms or time-series data in the 'Editor.' It ensures a more comfortable experience when reviewing long-duration driving data or comparing multiple pieces of information.
