 The Whisper model is intrinsically designed to work on audio samples of up to 30s in duration. However, by using a chunking 
 algorithm, it can be used to transcribe audio samples of up to arbitrary length. This is possible through Transformers

 ## Fine-Tuning
 
 The pre-trained Whisper model demonstrates a strong ability to generalise to different datasets and domains. However,
