Vienna Choir offers an extensive 27 GB collection capturing the full range of the human voice through soprano, alto, tenor, and bass ensembles. This vocal library features over 31,400 samples recorded at 44.1 kHz/24-bit quality, delivering rich and authentic choir sounds suitable for diverse musical productions. The library provides a wide variety of vocal articulations including staccato, sustained notes, crescendos, diminuendos, trills, glissandos, and unique effects such as clusters and breathing noises, enabling expressive and dynamic performances.

The voices in this collection were meticulously selected from Austria's leading choirs and recorded exclusively at the Silent Stage, ensuring exceptional tone, intonation, and consistency. The project demanded careful attention to the physical and technical aspects of vocal performance to capture the nuances of human singing accurately. This dedication results in a choir library that offers not only high-quality sound but also remarkable realism, suitable for composers and producers seeking authentic choral textures.

Vienna Choir comes in two versions: a Standard Library featuring multiple vocal articulations on the vowel 'a' and an Extended Library that adds articulations on the vowel 'u'. Both versions are compatible with AU, VST, and AAX Native/RTAS formats, supporting use as both plug-in and stand-alone software. This extensive vocal toolkit offers a comprehensive solution for creating intricate choral arrangements, cinematic scores, and other professional music projects requiring detailed vocal expressions.
