What is Tape Restoration? Tape restoration is the process of repairing and enhancing audio recordings that have deteriorated over time or have been damaged in some way. This can include removing noise, improving clarity, and restoring the overall quality of the recording. Tape restoration is commonly used in the preservation of historical audio recordings, such … Read more
What is Pitch Detection? Pitch detection is the process of determining the pitch or frequency of a sound signal. In music and audio processing, pitch refers to the perceived frequency of a sound, which is closely related to the fundamental frequency of the sound wave. Pitch detection is essential in various applications, such as music … Read more
I. What is Phase Noise Reduction? Phase noise reduction is a process used in audio engineering to minimize unwanted fluctuations in the phase of a signal. Phase noise refers to the random fluctuations in the phase of a signal, which can degrade the quality of audio signals. By reducing phase noise, engineers can improve the … Read more
I. What is Frequency-domain Processing? Frequency-domain processing is a method used in signal processing to analyze and manipulate signals in the frequency domain, as opposed to the time domain. In the frequency domain, signals are represented as a combination of sine and cosine waves of different frequencies, amplitudes, and phases. This allows for a more … Read more
What is Archival Audio? Archival audio refers to the preservation and storage of audio recordings for future reference or historical purposes. These recordings can include music, speeches, interviews, sound effects, and any other type of audio content that holds cultural, historical, or informational value. Archival audio is typically stored in specialized facilities or archives to … Read more
What is Phase Correction? Phase correction is a process used in audio restoration to align the phase of audio signals. In simple terms, phase refers to the timing relationship between different frequencies in an audio signal. When the phase of a signal is not aligned correctly, it can result in phase cancellation or phase distortion, … Read more
I. What is Wavelet Transform? Wavelet transform is a mathematical tool used for analyzing and processing signals. It decomposes a signal into different frequency components called wavelets, which are then analyzed individually. This allows for a more detailed and efficient analysis of the signal compared to traditional Fourier transform methods. Wavelet transform is particularly useful … Read more
What is Broadband Noise? Broadband noise refers to unwanted noise that covers a wide range of frequencies in an audio signal. This type of noise can be caused by various factors such as electronic interference, environmental factors, or equipment malfunctions. Broadband noise can manifest as a constant hiss, hum, or static in the background of … Read more
What is Forensic Audio Software? Forensic audio software is a specialized tool used in the field of audio forensics to analyze, enhance, and authenticate audio recordings for use in legal proceedings. This software is designed to extract and clarify audio information from recordings that may be distorted, damaged, or of poor quality. Forensic audio software … Read more
What is Spectral Repair? Spectral Repair is a technique used in audio restoration to repair and enhance audio recordings by targeting specific frequencies in the spectral domain. This process involves identifying and isolating problematic areas in the audio signal, such as clicks, pops, hums, hisses, and other unwanted noise, and then applying various tools and … Read more
