Digital and analog transcription

Analog transcription  and Digital audio transcription – a evaluation
Day by day, the Transcription service is growing into leaps and bounds. Its presence is required by each and every sector – business, education, media, law etc, and all need Digital transcription in one way or the other. All these segments need the transcription service for the audio and video recording of the various business meetings, seminar, interviews, lecture sessions conducted for their further analyses and development.
The audio and video recordings are done in both analog and digital formats.
The analog recording is done by converting the physical recording of sound into wave forms. The recording is done in analogous to the difference in air pressure. A transducer converts the air pressure into electrical signals. The electrical signals are then recorded by a recording device like a record cuter or magnetic tape. The digital recording is done by transforming the physical properties of the sound into a number sequence. This is stored and interpreted back for reproduction. The sound is converted into analog signal by a microphone and digitized by means of analog to digital converter
Though the digital transcription service is widely used, some customers may solicit service for analog transcription of their age old historical meetings, important interview etc. They need the transcripts, so that it may serve as an imperative tool to assess their performance. All these old recordings mostly would be in analog formats in the form of gramophone disc, wire recorders, cassette tapes, etc. The instrument used for dictation is the Dictaphones. Later the digital format came in the form of MP3 WAV, CD, and DVD. The digital voice recorders replaced the Dictaphones. There is no time constraint for the digital voice recorder; you can record as long as your wish. The tapes in contrast can hold only 60 or 90 minutes of recordings.
