In an equilateral triangle, placed around ear level and tilted slightly inward. A distance of 8-12 feet is preferred.

48kHz and 24 bit

A circuit called an analog to digital converter (ADC) creates a numerical representation of an audio signal’s amplitude and frequency.

The numerical representation of an audio signal is read by a circuit called a digital to analog converter (DAC), which allows the original analog signal to be recreated.

The time component of digital audio conversion. An incoming analog signal is sampled or “snapshotted” a certain amount of times per second, and each sample is assigned a binary number.

Pulse Code Modulation. It is a type of circuitry based on switches turning on/off to write binary code when converting audio to digital.

When the output of digital audio conversion doesn’t match the original analog wave input due to missing frequencies. This happens when the sample rate used was too low to capture all the frequencies within an audio signal.

The sampling rate must be at least 2x the frequency range of the signal.

The level/ dynamic range aspect of digital audio conversion. It uses binary code to record the amplitude of an incoming audio signal.

Most significant bits (1 bits) and Least significant bits (0 bits) Low signal levels encode as LSBs and high volumes signals encode as MSBs.

The quantity of binary digits used to represent an audio signal.

Each bit doubles the previous amount of levels. 1 bit = 2 levels 2 bit = 4 levels, 3 bit = 8 levels, 4 bit = 16 levels etc.

6dB

Instability between the encode and decode stages of digital audio recording.

Three. One or two clipped samples can light up on a digital meter, but our ears won’t perceive it as distortion.

Audio Engineering Society/European Broadcast Union. An XLR cable that carries two channels of stereo digital audio. NOT the same as an xlr mic cable.

Sony/ Philips Digital Audio Interface. A single pin RCA connector used to carry up to two channels of digital audio. Commonly found on consumer level equipment such as DVD players.

A consumer grade fiberoptic cable that carries 2 channels of digital audio. Some semi-pro audio gear uses these to carry up to 8 channels of audio.

Tascam Digital Interface. A multi channel of digital audio in and out (16 channels totals.)

Multiple Audio Digital interface Fiber Optic transmission of 28, 56, or 64 channels of digital audio, with sample rates of up to 96kHz and up to 24 bit depth.

Digital Audio Network through Ethernet. Used to carry large amounts of digital audio channels over a large distance.

The header, which store information such as the sample rate and bit depth, and the audio data, which is the raw binary code

A compression- decompression device used to reduce the file size of digital audio. There is Lossy and Lossless

Compression in which all the original date can be recovered when the file is decompressed.

Compression in which pieces of the original data are permanently removed from the file to reduce its size.

The number of bits processed per minute/ second.

- 18 dBFS

The reinforcement and unnatural lingering of certain tones within a room after the sounds stops, based on it’s size, shape, and material.
