If you’re not already familiar with sample rate and bit depth, they’re related to the digital to analog conversion process. When digital audio information is outputted by an audio source and sent into a digital to analog converter, or DAC, the DAC takes snapshots, called samples, of the information in order to convert the audio from its digital form and compile an analog waveform. The frequency at which the DAC takes these samples is known as the sample rate. ![]() Analog audio has various amplitude values in a single waveform.īit depth determines how many possible amplitude values can be recorded each time the audio is sampled.Ī CD’s sample rate is 44.1 KHz, which means there are 44,100 samples taken per second.īit depth is a bit more difficult to understand. 16-bit, 24-bit, and 32-bit are the most common bit depths.Īs the bit depth increases, more amplitude values can be recorded. Targets platform audiophiles adding 24bit qobuz full#Ī 16-bit bit depth can record 65,536 amplitude values.Īs bit depth and sample rate go up, this creates a more complete, accurate, and smooth reproduction of audio, reconstructing the analog waveform more precisely as the original digital information.īy definition, audio is considered to be hi-fi if it is lossless and capable of producing the full frequency range from recordings that were mastered from music sources that are better than CD quality. Hi-fi audio doesn’t have one specific standard as far as what is considered to be hi-fi, just as long as it’s over the standard for CDs. Hi-fi audio commonly has a sample rate of anywhere from 96 kHz to 192 kHz at 24-bit depth, and even higher in some cases. Like anything in life, there are pros and cons to hi-fi audio.
