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

Manufacturers ruin the fun and logic of music-making for young kids. Why make unplayable instruments?

Turtle shaped xylophone for babies

Turtle shaped xylophone for babies

I think in general, I am a positive guyโ€ฆHowever, 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!

BrandMR - Brandfilm This is "BrandMR - Brandfilm" by MOST on Vimeo, the home for high quality videos and the people who love them.

Worked on some heavy sound design for this one! Love how layered it is: in your face / subtle atmospheric. ๐Ÿ’ฅ๐Ÿƒโ˜„๏ธ๐Ÿœ๏ธ

The new Speech-to-Text feature from Pro Tools will be a game-changer for me!

Systemprefs Mac for App Shortcuts: Notes -Strikethrough

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 โ€” turns out itโ€™s ridiculously simple (see screenshot). Anyone else been there?

Matthijs Koster - Rift Riff (Original Game Soundtrack) Listen to Rift Riff (Original Game Soundtrack) by Matthijs Koster.

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. Itโ€™s playful, cheerful and headstrong. Just like Otto himself โค๏ธ

Total disk-space 70,43 GB โ€ข 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 ๏ฃฟMusic today: Apparently, you canโ€™t use the abbreviation โ€˜OSTโ€™ in your album title. I guess this is a stylistic choice they made? Went for Original Game Soundtrack instead. What do you think?
