There hasn’t been as much development of ADC microchips as with the DAC chips over the past 20 years so most of the modern technology is focused on getting a better signal to the chips With that said upgrading a converter with an external clock can can have a positive impact on the performance of the converter if the external clock is better and the connection between hardware units is good. Having a really nice internal clock is important for tracking as analog-to-digital clocking cannot be improved by jitter rejection like with digital-to-analog conversion. better clocking can also have a clarity to particularly the low frequencies in my experience. If you do tracking (recording) and have a great room+mic+preamp then you might want to invest in one of these ADCsĬlocking is really important to analog-to-digital conversion creating a better image to my ears in conversion shootouts. However the best converters can do things like create a more defined sense of space, or make someone who isn’t a critical listener notice the difference between preamps. If one is say, looking to master or sweeten an already-recorded digital signal then investing in a really good ADC (and DAC – digital-to-analog converter) could be more practical. The law of decreasing returns in audio gear. Just about all modern converters have extremely low noise floors and are generally suitable for most people’s needs. The room is more important than the microphone, which is more important than the preamp, which is more important than the converter. While the best analog-to-digital converter (or “ADC”) is different for everyone here is a list of the most worthy contenders (and thus brands) on the market today.īut first some advice: if you are planning to track your converter is probably not the weakest link in your recording setup. This entry was posted in More About…, Technical Library by Sean. The low-level signal is not required for non-converter devices. We recommend using the Signal-to-Noise measurement configured for dynamic range when testing other devices. For dynamic range measurements of other devices… The low-level tone (again, notched out before measurement) defeats this muting mechanism.Īt –60 dBFS, the tone is so low that any distortion products created are below the noise floor. In some DACs, the output of the device is switched off when there is no signal, providing an unrealistically quiet measurement.The low-level tone is removed by a notch filter before measurement. ![]() In the method here, a low-level tone is applied to the converter to avoid production of idle channel noise.
