Audio Restoration and Forensics Glossary

What is Plagiarism Detection? Plagiarism detection refers to the process of identifying and flagging instances of plagiarism in written or digital content. Plagiarism occurs when someone uses another person’s ideas, words, or work without proper attribution. This unethical practice undermines the integrity of academic and professional work, as it misrepresents the original author’s contributions and … Read more

I. What is Tape Print-through? Tape print-through is a phenomenon that occurs in magnetic tape recordings where the magnetic signals from one layer of tape are transferred to an adjacent layer, causing a faint echo or ghosting effect on the audio. This can happen when tapes are stored for long periods of time or when … Read more

What is Pop Removal? Pop removal is a process used in audio restoration to eliminate unwanted popping sounds that occur in audio recordings. Pops are sudden, sharp noises that can be caused by a variety of factors, such as microphone placement, vocal technique, or equipment malfunctions. These pops can be distracting to listeners and can … Read more

What is Attack/Decay Analysis? Attack/Decay Analysis is a method used in audio signal processing to analyze the transient characteristics of a sound signal. It involves examining the initial attack and subsequent decay of a sound wave to understand its timbral qualities and temporal behavior. By studying how a sound signal evolves over time, audio engineers … Read more

What is Background Noise Reduction? Background noise reduction is the process of minimizing unwanted sounds that can interfere with the clarity of audio recordings. These unwanted sounds, often referred to as noise, can include ambient noise from the environment, electrical interference, microphone hiss, or any other unwanted sound that detracts from the desired audio signal. … Read more

What is Voice Enhancement? Voice enhancement is a process used to improve the quality and clarity of audio recordings, specifically focusing on enhancing the voice or speech within the recording. This can involve removing background noise, adjusting volume levels, and enhancing the overall sound quality of the voice to make it more intelligible and easier … Read more

1. What is an audio codec artifact? An audio codec artifact refers to any unwanted distortion or degradation in sound quality that occurs during the compression and decompression process of audio data using a codec. Codecs are used to reduce the size of audio files for storage or transmission purposes, but this compression can sometimes … Read more

What is Signal Analysis? Signal analysis is the process of extracting meaningful information from signals, which can be in the form of audio, video, or any other type of data. In the context of audio, signal analysis involves analyzing the characteristics of sound waves to understand and manipulate them. This can include identifying and isolating … Read more

What is Signal Reconstruction? Signal reconstruction is the process of recovering a continuous-time signal from a series of discrete samples. In the field of audio processing, signal reconstruction is used to restore audio signals that have been degraded or distorted. By reconstructing the original signal, audio engineers can improve the quality and fidelity of the … Read more

What is Time-domain Processing? Time-domain processing refers to the manipulation of audio signals in the time domain, where the amplitude of the signal is plotted against time. This type of processing involves analyzing and modifying the waveform of the audio signal directly, without converting it into the frequency domain. Time-domain processing is commonly used in … Read more
