What is Analog Summing? Analog summing is a process in audio engineering where multiple audio signals are combined or summed together using analog circuitry. This is typically done in a mixing console or summing amplifier to create a final stereo mix of a recording. Analog summing is often used in conjunction with digital recording systems … 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 RMS (Root Mean Square)? RMS, or Root Mean Square, is a mathematical term used to describe the average value of a set of numbers. In the context of audio, RMS is often used to measure the average power of a signal. It is a more accurate representation of the signal’s amplitude compared to … Read more
What is a Spectrum Analyzer? A spectrum analyzer is a device used to measure the magnitude of an input signal versus frequency within the full frequency range of the instrument. It is commonly used in the field of audio engineering, telecommunications, and electronics to analyze the frequency spectrum of signals. Spectrum analyzers are essential tools … Read more
What is Saturation? Saturation in audio refers to the phenomenon where a signal reaches its maximum level and can no longer increase in amplitude. This can result in a warm, rich sound that adds depth and character to audio recordings. Saturation can occur naturally in analog equipment such as tape machines, tube amplifiers, and analog … Read more
What is LUFS (Loudness Units Full Scale)? LUFS, or Loudness Units Full Scale, is a measurement unit used to quantify the perceived loudness of audio signals. It is a standardized measurement that takes into account human perception of loudness, making it a more accurate representation of how loud a piece of audio actually sounds to … Read more
What is Vocal Riding? Vocal riding is a technique used in audio mixing to ensure that the volume level of a vocal track remains consistent throughout a song. This process involves manually adjusting the volume of the vocal track to even out any inconsistencies in the singer’s performance. By “riding” the faders or using automation, … Read more
What is a High-Pass Filter? A high-pass filter is an audio processing tool used in audio mixing and mastering to attenuate or eliminate low-frequency signals below a certain cutoff frequency. It allows higher frequencies to pass through unaffected while reducing or removing unwanted low-frequency content from the audio signal. High-pass filters are commonly used to … Read more
What is a Lissajous Figure? A Lissajous Figure, named after French mathematician Jules Antoine Lissajous, is a complex shape that is formed by the intersection of two sine waves at right angles to each other. When these two sine waves have different frequencies, amplitudes, or phases, the resulting Lissajous Figure can take on a variety … Read more
What is Reverb? Reverb, short for reverberation, is a sound effect that occurs when sound waves reflect off surfaces in an enclosed space and blend together to create a complex sound. It is the persistence of sound after the sound source has stopped, caused by multiple reflections of the sound waves. Reverb is a natural … Read more
