A great new open source tool which allows for SRT creation and editing is available from Nikse.   SRTeditor also includes WHISPER from OpenAI which we suggest is much better than our SPHINX AAT embedded tool.

Download SRTeditor from Nikse.  Place your WAV or MP4 video into a directory.  Open SRTeditor and select "audio to text" from the video top level menu. Click the batch mode button. Add your WAV files (Drag them if using windows) and press the "generate" button. This will generate srt files for each WAV.

Add metadata with the MCT 7.0.5 from ResCarta then use the DCT 7.0.5 WITH THE AAT CHECKBOX UNCHECKED.  

Easy, clean audio files with full search capabilites.
