5. Downloading the Edited CSV File

After making changes, you can download the modified file in different formats:

1. Click "Download as Jib Polars" to save the file as jib_polars.csv.

2. Click "Download as Genoa Polars" to save the file as genoa_polars.csv.

3. Click "Download as Spin Polars" to save the file as spin_polars.csv.
   
   

Each button saves the current table data into a CSV file named according to the selected sail configuration.

Quick Start Guide – Voice to CSV Data Recorder

The Voice to CSV Data Recorder simplifies collecting polar data by automatically formatting and saving your spoken values into a CSV file, ready for upload to Speed Polars apps—no templates needed. The app features a real-time data preview chart and an editable table for quick corrections.

How to Use

1. Open Vsk5 in windowed mode or on a second monitor for easy access.

2. Start a race and monitor TWS (True Wind Speed), TWA (True Wind Angle), and BS (Boat Speed) from your instrument panel.

3. Click “Start Dictation” and clearly say the values in order: TWS, TWA, BS.

4. After the third value, the app records the data, updates the live preview, and adds it to the CSV table.

5. If needed, edit values directly in the table; all changes will update in the preview and final CSV file.
   
   

Best Practice: Create a race with no wind shifts, and minimal wave height for steadier, more accurate polar readings and easier data collection.

Complete User Guide – Voice to CSV Data Recorder

Introduction

The Voice to CSV Data Recorder is a tool designed to streamline the collection of polar data from Virtual Skipper 5 (Vsk5). With built-in voice recognition, the app eliminates the need for manual data entry, allowing you to focus on sailing while automatically generating a correctly formatted CSV file.

Key Features

• No Templates Needed – The app automatically formats data into a CSV file, ready for use with Speed Polars apps.

• Live Data Preview – A real-time chart updates as data is collected, showing trends instantly.

• Editable Table – Easily correct mistakes within the app before saving the final CSV.

• Simple Operation – Just dictate values, and the app does the rest.
  
  

Step-by-Step Instructions

1. Setup

• Open Vsk5 in windowed mode or on a second monitor so you can access both the game and the recorder.

• Ensure you have a race environment with steady wind conditions for the most accurate data.
  
  

2. Start Recording

• Monitor your instrument panel for TWS (True Wind Speed), TWA (True Wind Angle), and BS (Boat Speed).

• Click “Start Dictation” and clearly say the three values in order:
  
  

  • TWS (e.g., “12.5”)

  • TWA (e.g., “135”)

  • BS (e.g., “8.2”)
    
    

• After speaking the third value, the app will automatically record the data and display it in the CSV preview and table.
  
  

3. Reviewing & Editing Data

• The table allows you to review and edit any incorrectly recognized values.

• Changes made in the table are automatically reflected in the CSV preview and the downloadable file.
  
  

4. Saving & Using the CSV File

• Once you’ve collected all necessary data, simply download the CSV file.

• The file is formatted and ready for direct upload into Speed Polars apps.
  
  

Best Practices for Accurate Data Collection

• Use Steady Conditions – Set up a race with no wind shifts and minimal waves for better TWS readings.

• Speak Clearly – Ensure background noise is minimal for accurate dictation.

• Verify Before Saving – Use the editable table to fix any errors before downloading the CSV.
  
  

With this simple process, you can efficiently collect and format polar data without needing spreadsheets or manual entry.
