• Audio Recording. This function captures sound from different input sources. Users can record from a microphone, a line-in input, or a sound card. Recording is done in digital format with configurable parameters such as sampling rate and bit resolution.
• Waveform Editing. This function provides direct visual manipulation of the audio track. Basic operations include cutting, copying, pasting, and deleting sections of the waveform. Precise editing is facilitated by zooming in on the waveform view down to the sample level.
• Applying Sound Effects. This module modifies the acoustic characteristics of the audio. Available effects include echo, reverberation, flanger, chorus, and pitch shift. Each effect has adjustable parameters to control its intensity and timing behavior.
• Audio Filtering and Enhancement. This function uses DSP tools to correct and improve sound quality. It includes low-pass, high-pass, and band-pass filters. It also offers capabilities for noise reduction and click removal.
• Mixing Tracks. This feature allows combining multiple audio files into a single composition. Tracks are superimposed or joined in sequence. The volume levels of each track are controlled independently to achieve the correct balance.
• Format Conversion. The program transforms audio files between different standards. It supports formats like WAV, MP3, WMA, OGG, AAC, and FLAC. Conversion includes modifying parameters such as bit rate and sampling frequency.
• Audio Extraction from Video. This tool separates the sound track from a video file. It works with common multimedia containers like AVI, MP4, WMV, and MKV. The extracted audio is saved as an independent file for further processing.
• Ringtone Creation. This function generates custom ringtones for mobile devices. Users select a fragment of a song or audio and export it in a phone-compatible format. The duration, start point, and end point are configurable.
• Spectral Analysis. This module shows a visual representation of the frequencies that make up the audio signal. The spectrogram allows identifying specific frequency components and their evolution over time. This view is used for detailed technical analysis.
• Sound Parameter Adjustment. This feature modifies fundamental audio properties. It includes volume control, normalization, balance adjustment between left and right channels, and changing playback speed without altering pitch.
• Multitrack Editing. This allows working with several audio tracks simultaneously. Each track is manipulated independently on the timeline. This function is fundamental for producing complex projects with layered sound.
• Saving and Exporting. The process stores the edited project on the hard drive. It offers options to save work in progress in a native format or export the final result in a standard audio format with customizable compression settings.

AVS Audio Editor was created by Ascensio System SIA., a company based in the United Kingdom. Initial development of the program began in 2004. The first public version was released in late 2004. The software is written primarily in the C++ and Delphi programming languages.
