 # Audiologger ZuidWest FM
 
-This repository contains a bash script designed to record audio streams on an hourly basis and log relevant metadata about the current broadcast. The script also ensures that audio old recordings are periodically cleaned up.
+This repository contains a bash script designed to record audio streams hourly and log relevant metadata about the current broadcast. It also ensures the periodic cleanup of old recordings.
 
 ## Features
 
-- **Continuous Recording**: Automatically records the audio stream from ZuidWest FM every hour.
-- **Metadata Logging**: Fetches and logs the current program name from the broadcast data API, providing context for each recording.
-- **Log File**: Maintains a detailed log file for tracking the script’s activities and any potential errors.
-- **Automatic Cleanup**: Removes audio files older than 31 days to free up space.
-- **Debug Mode**: Troubleshooting by providing additional output when enabled.

 ## Configuration
 
-Modify the script to specify the recording directory (`RECDIR`), log file path (`LOGFILE`), and other parameters:
-- `STREAMURL`: URL of the audio stream.
-- `RECDIR`: Directory where audio recordings are stored.
-- `LOGFILE`: File path for logging script operations.
-- `METADATA_URL`: API endpoint for fetching broadcast metadata.
-- `KEEP`: Number of days to retain audio recordings.

+- `KEEP`: The number of days to retain audio recordings.
 - `PARSE_METADATA`: Enables or disables metadata parsing from the Streekomroep WordPress theme.
 
 ## Usage
 
 Schedule the script to run every hour using cron:
 1. Open your crontab:
-   ```
+   ```bash
    crontab -e
    ```
 2. Add the following line to run the script at the start of every hour:
-   ```
+   ```bash
    0 * * * * /path/to/your/zwfm-audiologger/audiologger.sh
    ```
 
 ## Debugging
 
-To enable debug mode, set `DEBUG=1` in the script. This will output debug information to the console and help identify any issues during execution.
