Soundwoofer - Free Impulse Response Library

Not everyone has access to expensive amplifier speakers and impulse responses are the "spirit" of those physical devices in a digital format.

We belive that the ability to produce a great sound should be available to everyone.

So we built a library where we, as a community can collect them all.

Custom samples are here

2020-04-07

You can now upload your own sample


This update allows you to upload your own sample that you use to preview impulses with. Keep in mind that the sample you choose must be recorded in a special way.
Heres a guide on how to do that

To upload a sample head to your profile page, after you have done that you can select your own sample in the 'Select genre'-dropdown list.

We are aware that there might be some performance issues here and we are currently working on that

Enjoy!

Become a contributor - earn a pack

2020-02-08

Two library packs are available for bulk download.


We have received feedback about how useful it would be if the library was available for download as packs and we agree. So, therefore we have made two packs available. In order for you to get access to them we need something in return.

Pack one - Contains 350+ Impulses and can be found in your profile after you have logged in.

Pack two - Contains 1185 impulses and can be found in your profile after you have uploaded an Impulse of your own to the library.

A minor, less obvious update is that you now can use your email to login and not just your username.

Standalone impulses

2020-02-02

Standalone impulses are here!
We figured that uploading impulse responses to our library was a hassle for all of you.
So while we are working on a new way to create those sweet IR's we decided to add another section to the library:

Standalone impulse responses

These buggers do not require a connection to anything. The more you know the impulse you are adding the easier it will be for others to find it.
Simply select the file, give it a name and a nice description and you're set.
 
To celebrate the launch of this new section we have added about 1200 of them!
Check them out!

User account launch

2019-07-14

We have just opened up for user registrations,!
To create a user account use the 'Login' button in the upper right corner.

As a logged in user you can upload your own impulse responses to our library.

If you have any questions - feel free to send us a message at Facebook or email

Note that this is a very early access and we are releasing new features as soon as they are ready

Checkout the video by Carl on how to register and upload you impulses below!

How it works

The impulse response is the sound of the amplifier speaker. Every speaker has a particular sound quality which will drastically alter the result of any recording – no one speaker sounds alike! By capturing the frequencies of the impulse response on an amplifier speaker, and then transforming it into a simple .wav-file, you're able to replicate the exact sound of that speaker digitally. These -files are then made readily available on this site for you to dig into and start creating your next masterpiece.
