Until and unless you don’t know, what Digital and Analogue transcription services are? It’s pointless to directly jump on their elementary differences.
Digital transcription is primarily done on the advanced equipments with the sheer assistance of latest software whereas an analogue service is a conventional method of recording. In the analogue process, traditional and old equipments are employed while recording. Now, when you know what they are, the basic difference between them is quite understood. This not just applies to voice recordings (for transcription) but to all sorts of recordings.
In the analogue machine (tape cassette record) the sound gets recorded when the wave forms. On the other hand, the latest digital machines take the signal samples and record the sound by storing them as bits. In digital recording, these bits get stored in the similar manner in which data gets stored in the computer. In comparison to analogue system, the digital systems have got higher-signal-to-noise ratio. Here, the term noise refers to any sort of disturbing sound but in analogue it refers to “tape hiss”. So it’s crystal clear that the quality of digital recording is far-far better than the analogue recording.
In case you make a master copy of the analogue recordings, the sound quality automatically deteriorates because originally, the sound quality is poor. But in digital recordings you won’t end up facing such troubles, doesn’t matter how many copies you create, the sound quality will remain the same.
So people, now its upto you which recording technique to prefer? Do decide reckoning your requisite requirements.
Things we keep in mind before recording an interview for transcription. Check for microphones, headphones, cables, batteries, tapes etc.
