Endless WAV is a free software designed to create sustain loops in WAV files, supporting 8, 16, and 24-bit formats. It offers features such as loop mixing, automatic looping, real-time crossfade, as well as fade and cut functions, allowing users to easily mark loop areas within the waveform using simple keyboard shortcuts. This intuitive approach streamlines the process of preparing audio loops for further use.

The program is tailored to handle large multi-sampling projects with numerous individual samples, enabling efficient workflow through extensive key combination shortcuts for accessing most functions. Additionally, Endless WAV assists in sample organization by allowing batch renaming of entire folders of WAV files, embedding root key information into file names and headers with customizable patterns, making it easier to prepare samples for import into samplers.

Available for macOS (from OS X Yosemite 10.10 through Sonoma for Intel and ARM) and Windows (versions 7 through 11), Endless WAV supports a wide range of systems. Users can also find tutorials demonstrating its functionality, including sampling techniques, with subtitles available in multiple languages to facilitate learning across different regions.
