Echo removal is the process of removing echo and reverberation artifacts from audio signals. The reverberation is typically modeled as the convolution of a (sometimes time-varying) impulse response with a hypothetical clean input signal, where both the clean input signal (which is to be recovered) and the impulse response are unknown.
Negative indicate the echo is stronger than the original signal, which if left unchecked would cause audio feedback. The performance of an echo canceller is measured in echo return loss enhancement (ERLE), [3] [9] which is the amount of additional signal loss applied by the echo canceller. Most echo cancellers are able to apply 18 to 35 dB ERLE.
In 2003, US-based Mackie, a division of LOUD Technologies specializing in studio recording and live sound products, took over the distribution of Tracktion. It was sold in standalone, boxed retail versions and bundled with Mackie, Tapco, and Echo Audio computer-audio interfaces and digital-capable mixing boards.
Sound editing functions: cut, copy, paste, delete, insert, silence, auto-trim and more; Audio effects: amplify, normalize, equalize, envelope, reverb, echo, reverse and many more with VST plugin compatibility; Batch processing allows users to apply effects and/or convert thousands of files as a single function

Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo-like effect, whereby the original audio is heard followed by the delayed audio. The delayed signal may be played back multiple ...

WaveSurfer is an audio editor widely used for studies of acoustic phonetics. It is a simple but fairly powerful program for interactive display of sound pressure waveforms, spectral sections, spectrograms, pitch tracks and transcriptions. It can read and write a number of transcription file formats used in industrial speech research including ...
