By converting them into their digital counterparts, you can play them over and over again without fear of degradation. Over time, cassette tapes will demagnetize and LP records will begin to crack. Unfortunately, most analog media won’t last forever. Why Should You Convert Your Analog Media to Digital? Fortunately, this guide will break the process down into simple, easy to follow steps. Whatever the media, though, you’ll want to convert it into a digital format to better enjoy it. Indeed, you likely still have some old cassettes and cherished VHS tapes. However, even though digital media has come to dominate, it doesn’t mean that analog media has vanished completely.

From wristwatches to phones and even larger items like cars, everything has become digitized. Now, digital media reigns supreme wherever you look. Simply by listening and monitoring your HD Radio programming as you would your analog station will help keep your station sounding its best.Since the start of the 21st century, analog media’s time in the spotlight has come to an abrupt end. The radio listener will not tolerate a station that jumps back and forth in time or one in which he needs to constantly adjust the volume control. ** Time and level alignment is one of the most, if not the most important technical parameter when implementing HD Radio technology. The TX Gain should then be increased or decreased as needed to match the perceived analog audio loudness by monitoring a suitable HD Radio receiver.

The digital audio processor output should be adjusted to full scale to achieve the best dynamic range to the input of the Exciter/Exporter.The audio level alignment of the station should be checked at least once per week and adjusted as needed.The multicast channels should also be adjusted so that the apparent loudness difference between HD1, HD2, and HD3, (and HD4, if applicable) is not noticeable.The levels of the two streams should be within 1 dB of each other. However, in their absence they can be matched “by ear”. Audio level alignment is perceptual and should be adjusted using one of the monitors mentioned above.Multicast channels require no time alignment as they are independent of the analog and HD1 audio.There is also at least one HD Radio monitor manufacturer that is managing the analog audio in real time and adjusting the delay as needed. A few of the manufacturers are in the process of working on this solution. The ideal method of keeping the time alignment in tolerance is to have a split-mode receiver fed back into the exporter to automatically adjust the delay between the 2 streams.This audio can then be recorded and the time difference between the 2 channels observed on a simple audio editor.

If such a device is not available, then manual calibration should be done and periodic monitoring is suggested. This can achieved with the use of an automatic feedback receiver, which is highly recommended.
