What is Harmonic Distortion? Harmonic distortion is a type of distortion that occurs in audio signals when additional frequencies are added to the original signal. These additional frequencies are multiples of the original frequency, known as harmonics. Harmonic distortion can occur in various audio equipment, such as amplifiers, speakers, and recording devices, and can have … Read more
What is Speaker Identification? Speaker identification is the process of determining the identity of a speaker based on their voice characteristics. This can involve analyzing various aspects of the speaker’s voice, such as pitch, tone, accent, and speech patterns. Speaker identification is commonly used in forensic investigations, security systems, and voice authentication technologies. How is … Read more
What is de-noising? De-noising is a process used in audio restoration to remove unwanted noise from audio recordings. Noise can be introduced into recordings through various sources such as background interference, microphone hiss, electrical hum, or tape hiss. De-noising aims to enhance the quality of audio recordings by reducing or eliminating these unwanted sounds, resulting … Read more
What is Distortion Removal? Distortion removal is the process of eliminating unwanted distortions or anomalies from audio signals. Distortion can occur during the recording, transmission, or playback of audio, resulting in a degraded sound quality. By removing distortion, audio engineers can restore the original clarity and fidelity of the audio signal. How does Distortion Impact … Read more
What is the Short-Time Fourier Transform (STFT)? The Short-Time Fourier Transform (STFT) is a technique used in signal processing and time-frequency analysis to analyze non-stationary signals. It is a method of representing a signal in the time-frequency domain by computing the Fourier transform of short, overlapping segments of the signal. This allows for the analysis … Read more
What is Clipping Restoration? Clipping restoration is the process of repairing audio files that have been distorted due to clipping. Clipping occurs when the amplitude of an audio signal exceeds the maximum level that can be accurately represented by the recording or playback system. This results in a distortion of the waveform, leading to a … Read more
I. What is Evidence Handling? Evidence handling refers to the process of collecting, storing, preserving, and presenting evidence in a manner that maintains its integrity and reliability for use in legal proceedings. Proper evidence handling is crucial in ensuring that evidence is admissible in court and can be used to establish the facts of a … Read more
What is Audio Timestamping? Audio timestamping is the process of adding a time reference to an audio file to indicate when a particular event occurred. This time reference is crucial for various applications, such as audio restoration, forensic analysis, and quality improvement of audio evidence. By timestamping audio files, users can accurately track and analyze … Read more
What is Fast Fourier Transform (FFT)? Fast Fourier Transform (FFT) is a mathematical algorithm used to analyze and process signals in various fields such as audio processing, image processing, and telecommunications. It is a fast and efficient way to convert a time-domain signal into its frequency-domain representation. The FFT algorithm was first introduced by Cooley … Read more
What is Dereverberation? Dereverberation is a signal processing technique used to reduce or remove the effects of reverberation in audio recordings. Reverberation, also known as reverb, is the persistence of sound in a particular space after the original sound has stopped. This can occur naturally in environments such as concert halls or caves, or artificially … Read more
