Tool New!: Eternity Audio

Route the audio into the Granular Engine node. Turn up the "Spray" parameter to randomize where the grains are pulled from.

Convert your desired music (typically from .wav or .mp3 ) into a compatible format like .hca , ensuring the sample rate matches the original file (often 44100 Hz or 48000 Hz ).

The integrated bitcrusher and three filter types (low-pass, high-pass, and a vintage SEM option) within the feedback path let you shape the tone of your repeats progressively. As echoes build upon themselves, they can degrade into lo-fi textures or maintain pristine clarity depending on your settings. This "texture machine" approach to delay turns the feedback loop into a granular synthesis playground.

The tool functions as a bridge between standard audio formats and complex game archives: eternity audio tool

A stand-out feature of this library is its , which allows composers to make choirs sing "fake words" and even real texts much more easily than other comparable tools. The engine also uses a look-ahead feature that automatically times syllables, helping to prevent the muddy, unnatural phrasing that can plague these types of virtual instruments. This level of realism and playability makes it a powerful tool for creating authentic, human-sounding choral performances.

Traditional delays simply repeat what they receive, but Delay Eternity actively transforms the audio within its feedback circuit. The bitcrusher introduces digital degradation that intensifies with each repeat, while three filter choices (low-pass, high-pass, and the vintage SEM design) let you progressively strip away frequencies as echoes continue. This means your delays can start bright and clear, then gradually morph into gritty, filtered textures as they decay—perfect for dub production and experimental sound design.
