BOOM Library has released Death Whistle, a free collection of 179 royalty free sounds.

This FREE Sound Effects pack contains sounds from the Aztec death whistles. When raised to the lips and blown, they produce a shrieking sound so human that it can paralyze the listener in their tracks.

We found the death whistles exceedingly interesting for sound design so we decided to do high quality recordings of the instrument and give it away for FREE.

The 670MB pack includes 33 WAV files at 96kHz/24bit audio quality.
