Current issues and concerns

Again, as with digital video data, digital audio files may be large when created/stored in uncompressed formats and informed decisions need to be made when deciding when and how lower quality files are created. Another issue that is again similar to digital video is that the range of digital audio files consist of a mix of container formats and codecs which again emphasise the importance of detailed technical metadata in successfully identifying and working with audio files. Metadata also plays a key role with audio files in documenting the file’s creation process and contents (e.g. names and dates of interviews, locations, etc.) as these elements may not be as apparent as in similar video files.
