Digital audio, such as that on a CD, generally uses Linear Pulse Code Modulation (LPCM,
often referred to simply as PCM) to represent audio signals. LPCM works by taking
snapshots of the analog audio signal and assigning each a numerical value.
The resolution of an LPCM recording is determined by the sample rate (how many times
per second samples are taken) and the bit depth (how many bits are used to represent
each sample). Higher sample rates can capture higher frequencies, and higher bit depths
can accurately represent a greater dynamic range.
The standard for CDs is 16-bit 44.1kHz resolution, meaning that the analog signal is
sampled 44,100 times per second and each sample is given a value between -32,768 and
32,767. This resolution is often referred to as 44/16.
The Nyquist sampling theorem states that to accurately represent a signal one must use
a sampling rate double that of the highest frequency being represented. The highest
frequency audible to humans is around 20kHz; therefore a sampling rate of over 40kHz is
required to accurately capture the audible range of frequencies. Compact discs’ 44.1kHz
rate is adequate for this need.
Even so, many experts feel that using higher resolution PCM files during production
provides better-quality audio and a superior listening experience in the end product. For
this reason, 96/24 resolution is quickly becoming a standard format in the industry, and
it’s also common to see higher resolution files, such as 192/24
