What is a Helmholtz Resonator? A Helmholtz resonator is a type of acoustic resonator named after the German physicist Hermann von Helmholtz. It is a simple device consisting of a cavity with an opening that allows air to enter and exit. When sound waves pass through the opening, they cause the air inside the cavity … Read more
What is Green Glue? Green Glue is a viscoelastic damping compound that is used in acoustic treatments to reduce sound transmission between walls, ceilings, and floors. It is a non-toxic, water-based material that is applied as a layer between two layers of drywall, plywood, or other building materials. Green Glue is designed to convert sound … Read more
What is a Delay Unit? A delay unit is an audio processing device that is used to create echoes or repetitions of a sound signal. It is commonly used in audio production to add depth and dimension to a sound by creating a sense of space and distance. Delay units are often used in recording … Read more
What is Refraction? Refraction is the bending of a wave as it passes from one medium to another. This phenomenon occurs when the wave changes speed due to the change in the medium’s density. In the context of audio technology, refraction refers to the bending of sound waves as they travel through different mediums or … Read more
What is Warping in audio software? Warping in audio software refers to the process of manipulating the timing and pitch of audio recordings. This technique is commonly used in music production to align beats, adjust tempo, and correct timing errors in recorded tracks. By warping audio, producers can ensure that all elements of a song … Read more
What is a Reflection Panel? A reflection panel is a type of acoustic treatment used to control sound reflections in a room. These panels are designed to absorb and diffuse sound waves, reducing echoes and reverberations. Reflection panels are commonly used in recording studios, home theaters, conference rooms, and other spaces where sound quality is … Read more
What is a Blumlein Pair? A Blumlein Pair is a stereo recording technique that involves using two bidirectional microphones placed at a 90-degree angle from each other. This technique was developed by Alan Blumlein, a British engineer and inventor, in the 1930s. The Blumlein Pair technique is known for its ability to capture a natural … Read more
What is an Acoustic Model? An acoustic model is a statistical representation of the relationship between audio signals and the linguistic units they represent, such as phonemes, words, or sentences. In the context of speech recognition technology, acoustic models are used to map acoustic features extracted from audio signals to the corresponding linguistic units. This … Read more
What is Metadata? Metadata is data that provides information about other data. In the context of podcasting, metadata refers to the information that describes a podcast episode. This can include details such as the title, description, author, date published, duration, and keywords related to the content of the episode. Metadata plays a crucial role in … Read more
What is a Correlation Meter? A correlation meter is a tool used in audio recording and mixing to measure the phase relationship between two audio signals. It provides a visual representation of how closely aligned two signals are in terms of phase, which can help audio engineers ensure that their recordings are in phase and … Read more
