This script combines multiple audio files into a single MP3 file. It is specifically designed to process .wav files in a given directory, sorting them based on timestamps in their filenames and optionally filtering by talkgroup IDs and a specific time range.

• Timestamp Sorting: Orders audio files based on the timestamp embedded in their filenames.
• Talkgroup Filtering: Optionally filters files by talkgroup IDs.
• Time Range Filtering: Optionally filters files within a specified start and end time.
• Format Conversion: Converts .wav files to .mp3 and combines them into a single MP3 file.

• Python 3
• pydub library
• ffmpeg
• pytz library

Before running the script, ensure you have Python 3 installed on your system. You can install the required Python libraries using pip:

pip install pydub pytz
