Momentum
What it is
Momentum is a free loop and sample plugin and application for editing loops and shaping sound. It works with leading DAWs and can also run as a standalone app on Mac and PC. The web edition lets users browse, audition, and download from the Big Fish Audio catalog, with filters for instrument, genre, key, tempo, and other attributes. Users can apply 18 effects to individual loop sections, including pitch, stutter, delay, and reverse. Each slice receives a MIDI note automatically, so users can rearrange and play the sections. The free app accepts WAV and AIFF files. Momentum Pro adds MP3 support, importing and organizing personal audio, and individual loop purchases. Pro subscribers receive monthly or annual points for adding samples, kits, or full products to their account; the price is not shown. Listed minimum requirements are Windows 10 or later (64-bit) or macOS 12 Monterey or later, 8 GB RAM, 1440×900 resolution, and an internet connection. Big Fish Audio says legitimate purchases grant unlimited rights to use its license-free sounds in musical compositions without additional license fees.
