Digital Recording vs. Analog Recording for Transcription

High quality and efficient digital recording equipment has made digital recording superior to analog recording for transcription.

Analog audio tapes were the only source to record sounds for many years. In this new era, the ease of recording, storage and data transfer has made digital recording the preferred option for transcription in all industries. Digitally recorded data will not deteriorate over time. Digital recorders have also simplified the transcription job to a great extent. Even in courts where confidential matters are discussed, court reporters use digital recorders to transcribe the reports.

According to a September 2013 report from the National Center for State Courts, a number of states and territories have implemented digital recording in their general jurisdiction courts. New Jersey uses digital recording in approximately 90% of its court sessions, Massachusetts in 40% and Minnesota in 25%.

While digital formats include CDs, DVDs and Mp3, analog formats include cassette tape and wire recorders. Quality records can make your transcription affordable and error-free. It’s crucial to understand the pros and cons of both the recording types before settling for one.

What is the real Difference?

Quality: With poor audio quality, the transcriptionist’s effort will be more, adding to the cost of your transcription. While analog technologies record wave forms, digital technologies have the unique capability of converting physical properties of sound to a sequence of numbers and storing them as bits of data, similar to a computer storing information. Digital recordings do not involve recorder induced noises such as the tape hiss, and so are of better quality. Quality of the audio is comparatively poor with analog recorder when compared to digital, resulting in poor quality transcripts.

Easy manipulation: With a digital recorder, you can remove the unnecessary parts that need not be transcribed. With the recorder’s time stamp that displays time to the second as 00:00:00, it is easier to ask the transcriptionist to transcribe the records from the noted time may be from “5 minutes 20 seconds to 30 minutes 10 seconds.” This makes the transcription job easy as well. This is not the case with the analog media. Though minute counters are available, the level of accuracy is poor with tape players.

Re-listening to the audio files:  Another major advantage you have with a digital recorder is that you can identify the exact time an inaudible word occurred. By noting the time the transcriber can listen again to the particular word alone, rather than listening to the entire record, and spending hours on it. With an analog tape, it’s not possible to note the time of the inaudible word, though the transcriber can note the word and listen to it by flicking back and forth to find the word, which can be time consuming.

Rerecording: Rerecording or duplicating the original in analog recorders can impact the quality of the sound, resulting in transcription errors. Digital gadgets are compatible with computer USB ports, resulting in easier audio transfer to a computer. The copies produced using these gadgets have the same quality as the original recording.

File types: While a transcriber can work with any type of analog cassettes or video they may not be able to transcribe work with all digital file types. In digital, files are basically compressed by a codec. With this the file gets very small and can be easily uploaded or downloaded. Transcription software should have access to the codec used to compress the file. Audio files without compressing can be really big. Different file formats include .WAV, .WMA, .DSS and .CDA. While using digital recordings, make sure the transcriptionist can work with your file type.

File transfer: Rather than posting the audio cassettes to the transcriptionist, it is much easier and affordable to transfer the digitally recorded files onto your computer and send them to the transcriptionist via email, FTP or any file sharing sites. Recording can also be done directly onto a computer hard-drive using various types of software and an external microphone.

Reliable transcription outsourcing services help their clients meet their varied needs with accurate transcripts at a competitive cost. With excellent quality records, transcription accuracy increases. Comparing the two types of recordings, digital recording is more advantageous than analog recordings.
