From the project
Recreate the sound of mechanical spinning HDDs on retro PCs that use a solid state drive
Inspired by seeing the HDD Clicker project and wanting to more faithfully recreate the sound of old mechanical hard drives spinning up and accessing data. Because the hard drive sounds come from samples, it's possible to replace them with any hard drive recording you'd like or something completely different!
- Sample based recreation of mechanical hard disk drives operating sounds - Spin up when PC is turned on - Idle hum whilst standing by - Access clicks and crackcles - Spin down when PC is turned off - SD card to hold multiple HDD sample packs, to recreate the sound of different…
