About the Sound Effects Library

This sound effect library delivers a comprehensive collection of designed alarm sounds covering all types of alarm: small and large, high tech and vintage sounding, distorted and clean, complex and simple, fast and slow, continuous sirens, harsh buzzers and subtle beeps.

We designed all alarm sounds in this collection from scratch. This enabled us to have precise control over all variants, modulations and the types of sounds we wanted to include, not limited by the availability of physical devices and their constraints. As a side effect all sounds are 100% isolated from any ambience and mostly void of any room acoustics, giving the sound designer the flexibility to dial in the acoustics as needed.


The core of the library consists of 100+ long, un-looped sounds around 1 minute each in duration. “Beeps” and “buzzers” have a noticeable pause between each sound (e.g. digital alarm clock) and “sirens” change pitch continously (e.g. air raid sirens). Most sounds in this collection were created using analog and tube audio equipment so there are small imperfections and fluctuations over time, giving the sounds more realism and character.


To provide more detailed control over the type of alarm sound and enable you to create your own variations we created a construction kit, consisting of 100+ short, individual, loopable alarm sounds. As shown in the audio example below simply copy and paste (or loop) the construction kit elements to create a continuous alarm sound of the required length and rate.

The construction kit adds the following advantages:

• Control over the interval between individual beeps.
• Unlimited length.
• For game designers: Easy implementation as a loop, small memory footprint.
• Mix and match different construction kit elements to dial in exactly the sound you need.
