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
What is Tape Speed Correction? Tape Speed Correction is a process used in audio restoration to adjust the playback speed of analog recordings to match the original recording speed. Analog tape recordings can experience speed variations over time due to factors such as equipment wear, temperature changes, or improper storage. These speed variations can result … Read more
What is de-crackling? De-crackling is a process used in audio restoration to remove crackling noises from audio recordings. Crackling noises are often caused by imperfections in the recording medium, such as vinyl records or magnetic tapes, or by damage to the recording over time. These noises can be distracting and can degrade the overall quality … Read more
What is Audio Enhancement? Audio enhancement refers to the process of improving the quality of audio recordings by reducing noise, enhancing clarity, and improving overall sound quality. This can involve a variety of techniques and tools to enhance audio recordings for a variety of purposes, such as music production, film and television post-production, forensic investigations, … Read more
What is Audio Interpolation? Audio interpolation is a digital signal processing technique used to estimate missing or corrupted audio data points by analyzing the surrounding data points. This process involves filling in the gaps in a signal to create a smooth and continuous audio waveform. By using mathematical algorithms, audio interpolation can reconstruct missing audio … Read more
