Quick Tip: How to Make a Heartbeat Sound in Absynth


Have you ever wanted to make your own heartbeat sound to accompany your tracks or to add drama? Here's a quick tip how to make it in five easy steps using Absynth.

Note: The audio examples for this quick tip are quite low, and you may not be able to hear them well through laptop speakers. For best results, listen to them through monitor speakers or decent headphones.

Step 1

Open Absynth and create a new sound. In a Patch window, there is only OSC A active with its default parameters. Enable OSC B and change the Trans value to 12. Set the output volume of this Oscillator to -8dB. Finally Enable OSC C and set Trans to -12 and the volume to -1.5dB. You'll get a fuller sound in two octaves. This heartbeat sound works best in a low range around C1.

Step 2

In an LFO window, enable LFO 1 and change Sec to Beat, if you want your heartbeat sound to follow the track tempo. Set the value accordingly. In this example I used the default value 1 and set the track tempo to 60 BPM. Now set the Filter Freq to 100. Finally, turn on the Retrigger button at the bottom, because you'll need to put a MIDI CC message in the right place of your track to link your heartbeat sound with the beat properly.


Step 3

To make LFO 1 work, go back to the Patch window and add LPF 4 Pole Filter in a Master section. Increase dB to 1.
