11 free resources to pad your sound effect library

A blue moon with a stylized EQ

When your first starting as a sound designer, it can be incredibly expensive to build your sound effects library.  While there are a multitude of free sound effects libraries and catalogs online, many like Freesound don’t curate their content and often have SFX resources that are poorly recorded or now up to professional quality.

What do you mean “professional quality?”

A number of free sound effects are recorded at a 44.1 kHz sample rate or higher than 16-bit audio bit depth.  This means that the samples may sound great to the ear, but you’ll find them lacking when it comes to the quality when trying to manipulate the sounds, especially if, like me, you use a lot of pitch shifting and stretching.  

Instead, look for SFX collections that are recorded at a 96 kHz or 192 kHz sample rate, and for maximum stretch and pitch flexibility, your audio bit depth should be 24-bit or higher.

2. Free To Use Sounds

Free to Use Sounds is a huge boon to sound designers with their free and paid sound libraries. If you’ve got the money to spare, their $23 all-in-one bundles is a steal, with 1.6 TB of SFX for your collection.

Curated, but lower quality

These collections offer curated, lower quality (48/24 or less) sound effects recorded by professional field recordists.  Many of the sites offer premium HD versions at a price.

A great resource with free SFX in MP3 format.  WHile not ideal for major sound design, they have an extensive library of sounds to use.
