An MP3 sound effect in your project, made from a text description.
About
Writes an MP3 sound effect into your project from a description of the source, material, space and how the sound starts and fades. Effects run from 0.5 to 30 seconds (10 by default). It can make a seamless loop for ambience, and it can cut the silence off the start so a hit or a whoosh lands on the beat.
By default the effect is loudness-normalised (-16 LUFS). Normalising and trimming need FFmpeg, and if either fails the untouched audio is kept.
Each effect is a paid model call, billed by the length you ask for. In Syvon a typical 10-second effect costs about $0.04.
