What is Forensic Transcription? Forensic transcription is the process of converting audio recordings into written text for use in legal proceedings, investigations, or other forensic purposes. This specialized form of transcription requires a high level of accuracy and attention to detail, as the transcribed text may be used as evidence in court cases or other … Read more
What is LPC (Linear Predictive Coding)? Linear Predictive Coding (LPC) is a method used in audio signal processing to represent the spectral envelope of a digital signal. It is commonly used in speech and audio compression, as well as in audio restoration and forensics. LPC analyzes the audio signal by modeling it as the output … Read more
What is Transient Detection? Transient detection is a process used in audio signal processing to identify and isolate short-duration, high-intensity sound events within an audio recording. Transients are characterized by their sudden onset and rapid decay, making them stand out from the rest of the audio signal. These transient events can include drum hits, cymbal … Read more
What is Audio Authentication? Audio authentication is the process of verifying the authenticity and integrity of audio recordings. It involves analyzing various aspects of the audio, such as the waveform, frequency spectrum, and metadata, to determine if the recording has been tampered with or altered in any way. Audio authentication is commonly used in forensic … Read more
What is Audio Masking? Audio masking refers to the phenomenon where the presence of one sound makes another sound less audible or even completely inaudible. This occurs when two sounds overlap in frequency and intensity, causing the human ear to perceive only the louder or more dominant sound while masking the quieter or less dominant … Read more
What is Audio Source Separation? Audio source separation is a process in which individual sound sources in a mixed audio signal are separated and isolated from each other. This technique allows for the extraction of specific sound sources, such as vocals, instruments, or background noise, from a complex audio recording. By separating these sources, audio … Read more
What is Audio Fingerprinting? Audio fingerprinting is a technology used to identify and analyze audio content based on its unique characteristics. It involves creating a digital fingerprint of an audio file by extracting key features such as frequency, amplitude, and duration. This fingerprint can then be compared to a database of known audio fingerprints to … Read more
What is Principal Component Analysis (PCA)? Principal Component Analysis (PCA) is a statistical technique used to simplify complex data sets by reducing the number of variables while preserving the most important information. It is a dimensionality reduction method that transforms the original variables into a new set of uncorrelated variables called principal components. These components … Read more
What is Speech Enhancement? Speech enhancement is a process used to improve the quality and intelligibility of speech signals that have been corrupted by noise or other distortions. It involves the application of various techniques to enhance the clarity and overall quality of speech, making it easier to understand and interpret. How does Speech Enhancement … Read more
What is Cepstrum Analysis? Cepstrum analysis is a signal processing technique used to analyze the frequency content of a signal by examining its spectrum in the quefrency domain. The term “cepstrum” is derived from the word “spectrum” spelled backward, highlighting the reverse process of analyzing the spectrum of a signal. By taking the inverse Fourier … Read more
