Ultrasonic Death Whistle LE (UDW-LE) is a free light edition of MNTRA's UDW and UDW-X instruments, with a small selection of their sounds. It runs in MNTRA's MNDALA 2 engine.

It was performed by MNTRA founder, composer and multi-instrumentalist Brian D'Oliveira, from his collection of pre-Columbian Aztec death whistles, some handcrafted in the studio. The vendor says these sounds were used in several AAA video game soundtracks.

Each sample map is a different death whistle, named for its character: Ehecatl (Wind), Ixehua (Ghost), Yuualtotome (Night Bird), Cuaxicalli (Skull), Huentlalia (Altar) and Ozomatl (Monkey). 10 presets, up to 13 round robins.

Recorded at 32-bit 384 kHz, played back at 24-bit 96 kHz. 2 GB installed, 5 GB required for setup.
