Rift Riff's audio guy @matthijskoster.com just HALVED Rift Riff's binary size! we were already using Vorbis compression (file ext: .ogg) but found that setting the export quality to the lowest number possible barely made a difference in audio quality, yet reducing file size by 75-90%! #gamedev

overview of binary size of Rift Riff, more than halved from 1.8GB in total to 855MB

I think in general, I am a positive guy…However, there are a few things I REALLY hate, like: out-of-tune baby instruments. This cute little turtle, for example, has a totally off-key upper section, but the hardest part: the lowest note sounds the highest. Although, I do like the eye being a bell!

Worked on some heavy sound design for this one! Love how layered it is: in your face / subtle atmospheric. 💥🍃☄️🏜️

The new Speech-to-Text feature from Pro Tools will be a game-changer for me! “Did we record this?” won’t be a long, painful, time-consuming question anymore. And that’s not the only thing that’s good about this update.👌

As an Apple Notes power user, the one thing that always bugged me was the lack of a keyboard shortcut for Strikethrough. After running into it for the thousandth time, I finally looked it up — turns out it’s ridiculously simple (see screenshot). Anyone else been there?

Our son Otto is almost 6 months old! I thought it would be fun to celebrate it by naming a song after him. I made this piece of music in 3 hours, in a creative burst. It’s playful, cheerful and headstrong. Just like Otto himself ❤️ Listen: play.mw.fm/rift-riff-or...

Total disk-space 70,43 GB • music & sounddesign for Rift Riff Just calculated all folders together. I guess I could work a little more economically, but it doesn't feel like all that much for a year of work.

Learned something about Music today: Apparently, you can’t use the abbreviation ‘OST’ in your album title. I guess this is a stylistic choice they made? Went for Original Game Soundtrack instead. What do you think?

Rift Riff is OUT NOW! I took a leap and let go of most of my freelance work to focus on this game. I never expected it to take a year and a half—but here we are! :D It’s been creatively exhilarating working with the team, and I’m so proud of the little game we’ve built. #godot #pixelart #indiedev

Almost a year in and building this game has been AWESOME! Building a game with this team* has taught me a lot: gamers are dedicated, people building games even more. And the best part: unlike other projects I work on, with games, you DO get (unfiltered) feedback from the audience. Go play, have fun!

This is our #godot audio busses setup atm. I like to keep all bus-levels at zero and adjust the ceiling level of the HardLimiters instead. The Compressors have sidechains from other busses so, for instance, Interface sounds push back other sounds. What is your take on this?
