Sound Waves and Frequency
Sound waves are vibrations that travel through the air, and they’re measured in frequency (Hz) and amplitude (decibels). The human ear can detect frequencies between 20 Hz and 20,000 Hz, and most audio recording equipment is designed to capture this range.
Audio Signals and Bit Depth
Audio signals are the electrical representations of sound waves, and they’re measured in bit depth (16-bit, 24-bit, etc.). Bit depth determines the dynamic range and resolution of the audio signal. A higher bit depth generally results in a more detailed and nuanced sound.
Sampling Rate and Resolution
The sampling rate determines how often the audio signal is captured, measured in samples per second (44.1 kHz, 48 kHz, etc.). A higher sampling rate generally results in a more accurate representation of the sound wave. Resolution refers to the number of bits used to represent each sample, with higher resolutions resulting in more detailed sound.
