Audacity is a free and open-source digital audio editor and recording application software, available for Windows, macOS, Linux, and other Unix-like operating systems. [4] [5] As of December 6, 2022, Audacity is the most popular download at FossHub, [8] with over 114.2 million downloads since March 2015.
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
An example of this is a low-cut or rumble filter, which is used to remove infrasonic energy from a program that may consume undue amplifier power and cause excessive diaphragm excursions in (or even damage to) loudspeakers. A low-pass filter only modifies the audio signal by removing high
In a traditional recording studio additional rackmount processing gear is physically plugged into the audio signal path to add reverb, compression, etc. However, a DAW can also route in software or use audio plug-ins (for example, a VST plugin) to process the sound on a track.
Slowed and reverb (stylized as "slowed + reverb") is a technique of remixing and a subgenre, derived from chopped and screwed hip-hop [12] and vaporwave, [13] which involves slowing down and adding reverb to a previously existing song, often created by using digital audio editors such as Audacity.
Overdubbing (also known as layering) [1] is a technique used in audio recording in which audio tracks that have been pre-recorded are then played back and monitored, while simultaneously recording new, doubled, or augmented tracks onto one or more available tracks of a digital audio workstation (DAW) or tape recorder.

Solid-state flanging devices fall into two categories: analog and digital. The Eventide Instant Flanger from 1975 is an early example of a studio device that was able to successfully simulate tape flanging using bucket-brigades to create the audio delay. [13] The flanging effect in most newer digital flangers relies on DSP technology. Flanging ...
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.
