What people are saying about Sound Byte:

We have an Internet Radio Station and have been on the air for over two years. We air a "Live Call In Program" on Wednesday nights and yesterday was the first night we used Sound Byte and it worked without a hitch... SUPER Product! - Wes

Thanks to Black Cat Systems, the best part of the cart idea is back again and in a digital audio format that makes it a must for anyone in theater, radio or recording. It's awesome! All the sounds you need, right at your fingertips. - Joey Stuckey, award-winning guitarist, songwriter, singer, composer, producer, radio personality, teacher, and sound engineer.

LOVE the app, worth EVERY penny and would have easily paid more for it. Kills any other live radio app we've used. Even the bloated several hundred dollar apps... Love it love it love it. Thanks again! - JMack

This program is quicker and more user friendly than any hardware based unit out there. I use this program EVERYDAY while mixing network television and could not work without it. Thank you for a great product. - Randy P.

I like this Sound Byte thing a lot! It's pretty nice stuff. I can play any files no matter where they are, even if they are on a different hard drive. Nice! - Fred C.

After using your software for our hockey games the parents stuck running the music are very pleased on how easy this program made our job simpler. - Guy W.

I love Sound Byte, I use it on my radio show every morning and everyone is blown away at how I can whip the pants off anyone using one of those hardware based units. - Scott P.

I just wanted to say, WOW, Sound Byte is truly an awesome program. I love the simplicity, instant response, and the compatabilty with every sound file I can think of. I never buy software, but I bought this within minutes of trying it out. - Jeffrey H.

I sure love SoundByte. I run the music for some of our local minor hockey teams and it works famously. I have had several people ask me about it and they are really impressed when I tell them about the free trial and the very reasonable registration cost. Thanks for making such an excellent product. - Trevor G.

I love the product. I host a morning news/talk show in Lansing Michigan. I've always used a lot of audio, but my studio producer had to insert the audio which is a coordination issue (especially with drop-ins, quick sound bytes etc.). Now I have total control over audio. - Walter S.

Your program has made running sound cues in our little non-profit theatre very easy. For the money, there is nothing out there that compares. Thank you for keeping it affordable! - Mark C.

SoundByte Enhances Radio/Podcast production - Craig Crossman

Note for Catalina/Big Sur users: if you check the automatic graphics switching box in the Energy Saver system preferences, there can be a delay before carts starting playing. So we recommend you keep this box unchecked.
