Audacity vs SpectraLayers Pro

Audacity is a free, open-source audio editor for Windows, macOS, and Linux desktop computers. It supports multitrack editing, noise reduction, video synchronization, and cloud collaboration. Common audio formats include MP3, M4A, AIFF, FLAC, and WAV, and it handles 16-bit, 24-bit, and 32-bit audio with high-quality resampling and dithering. A Spectrogram view helps visualize and analyze audio clips. Third-party plugins are supported, including VST3, Nyquist, LV2, and Audio Unit formats. Its source code can be viewed or modified under the GNU GPL, and no subscription is required. Audacity has no mobile version for iOS or Android, despite those platforms appearing in some listings. The software is developed by a small remote team supported by the community. Help is available through a manual, forum, and developer Discord.

SpectraLayers Pro is a spectral audio editor that presents sound as visual objects for editing, repair, restoration, and sound design. Pro 13 adds Unmix Sound Effects to separate short sounds from continuous backgrounds such as wind, crowds, traffic, and nature. Ambience Heal fills gaps using ambience from the source layer, while Reconstruct resynthesizes selected spectral data. Voice DeClick removes mouth noises, and Voice DeCrosstalk isolates unwanted voices from a target voice. The software supports batch processing and can run standalone or as an external editor. Listed integrations include Ableton Live, Final Cut Pro, Logic Pro, Reaper, DaVinci Resolve, FL Studio, ACID Pro, Vegas Pro, KONTAKT, REAKTOR, HALion, and Tracktion Waveform; edited audio can be returned to the calling app. Pro 13 supports specified recent macOS releases on Intel and Apple silicon, and Windows 10 or 11 64-bit from version 21H2; Windows 11 on Arm requires 24H2 or later. A free trial is available, but no free plan or price is listed.
