Kvlt was developed with 64bit in mind. Because we don't have to support legacy 32bit architectures we can offer features like unlimited recording time and support for files that are larger than 4GB.

Kvlt supports the most common file formats like .wav, .aiff, .m4a, .aac and m4r. But we're constantly working to include support for more formats like .ogg and .snd.

We didn't just want to make yet another audio recorder for the Mac - we wanted to make it beautiful and easy to use. And we think we did a great job on that. Kvlt can be used by anyone who knows that a red circle means "record".

About Kvlt

Why did we make Kvlt?

For our work we often need small sound snippets. Sadly there are no simple and usable audio recorders for the Mac. You had to use full blown "digital audio workstation"-software - which is overkill. It takes time to learn these complicated products. It takes time to start up that software. And the editing itself takes time too.

So we made Kvlt. It's simple to use yet powerful enough to produce high quality sounds. And it's blazing fast. Kvlt is the audio recorder that should have been included with OS X but sadly was omitted.

The design behind Kvlt

There are some audio recorders out there for the Mac. But they are no fun to look at. They might work but working with them doesn't feel right. So we spent a considerable amount of time on Kvlt's user interface. It had not only to be highly usable - it also had to look awesome. And we think our designer Simon did a great job!

The technology behind Kvlt

Some might think writing a sound recorder would be trivial. And if you do it the lazy way and use high level APIs then it is trivial. But doing it the lazy way would mean trade-offs. And we don't like trade-offs. Other than that our design required fancy functionality like a real time scaling waveform and real time spectral analysis. No way you could do that with high level APIs. So our programmer Leon wrote a highly sophisticated audio engine to power Kvlt. The engine is so advanced that it could power a "digital audio workstation" program on its own.

The future of Kvlt

Kvlts advanced audio engine means that we have many options to extend Kvlt. We plan a lot of awesome features (like support for AU audio plugins) for coming versions. So stay tuned ...
