What is a direct signal in recording? A direct signal in recording refers to the original audio signal that is captured without any added effects or processing. It is the raw sound that is recorded directly from the source without any alterations. Direct signals are often used as a starting point in the recording process … Read more
What is Hertz (Hz)? Hertz (Hz) is the unit of measurement used to quantify frequency in cycles per second. It is named after the German physicist Heinrich Hertz, who was the first to conclusively prove the existence of electromagnetic waves. In the context of sound and audio technology, Hertz refers to the number of vibrations … Read more
What is FM (Frequency Modulation)? FM, or Frequency Modulation, is a method of encoding information on a carrier wave by varying the frequency of the wave. This modulation technique is commonly used in radio broadcasting to transmit audio signals over the airwaves. FM is known for its ability to provide high-quality sound and resistance to … Read more
What is Blu-ray Audio? Blu-ray Audio is a high-definition audio format that offers superior sound quality compared to traditional audio formats such as CD or MP3. It is designed to provide listeners with a more immersive and detailed listening experience, allowing them to hear every nuance and subtlety in the music. How does Blu-ray Audio … Read more
What is a Ground Loop? A ground loop is an unwanted electrical current that occurs when there are multiple paths to ground in an electrical system. This can create a loop of current flowing through the ground wire, causing interference and noise in audio systems. Ground loops are a common issue in live sound setups, … Read more
What is a Free Field? A free field refers to an acoustic environment where sound waves can travel freely without any reflections or obstructions. In a free field, sound waves propagate in a straight line from the sound source to the listener without being altered by any surfaces or objects in the environment. This type … Read more
What is True Peak Metering? True Peak Metering is a method used in audio processing to measure the absolute peak level of an audio signal. It provides a more accurate representation of the peak levels in a signal compared to traditional peak metering, which may not accurately capture peaks that occur due to inter-sample peaks. … Read more
What is an Audio Bus? An audio bus, also known as a signal bus or simply a bus, is a virtual pathway that allows multiple audio signals to be routed and processed simultaneously within a digital audio workstation (DAW) or mixing console. Think of an audio bus as a highway for audio signals to travel … Read more
What is Crest Factor? Crest Factor is a term used in audio engineering to describe the ratio between the peak level and the RMS (Root Mean Square) level of a signal. In simpler terms, it is the difference between the loudest and quietest parts of a sound wave. A high crest factor indicates a signal … Read more
What is an Acoustic Tile Ceiling? An acoustic tile ceiling, also known as a drop ceiling or suspended ceiling, is a secondary ceiling installed below the main structural ceiling of a room. These ceilings are typically made up of a grid system of metal tracks suspended from the main ceiling, with acoustic tiles placed within … Read more
