A method for creating a metadata enriched digital media file comprises (i) providing digital media tie (step Al) containing digital audio data, the digital audio data comprising digital speech audio content (ii) analysing the digital speech audio content (step A2) using a speech-to-text processing engine to identify key text-data in the digital speech audio content, (iii) storing the identified key text-data as metadata (step A3), and (iv) attaching the metadata to the digital media file (step A4). The digital audio data may additionally comprise digital non-speech audio content, and the method may thus further comprise separating the digital speech audio content and the digital non-speech audio content (step A5, Figure 2) prior to analysing the digital speech audio content. The method may additionally comprise analysing the digital non-speech audio content using a non-speech audio processing engine and generating text information descriptive of the analysed digital non-speech audio content (step A6, Figure 2), and may further comprise storing the generated text information as part of the metadata (step A7, Figure 2) before attaching the metadata to the digital media file (step A4, Figure 2).
