By allocating the SDL2 audio buffer in default native format (usually 44100hz), and upsampling the audio data in emulator, most of this problem was eliminated. Even though it worked on Mac Pro, for example on M1 Macs it caused the audio in other applications to start cracking and breaking up. Originally the audio buffer with 22255 Hz sample rate was passed directly to SDL2, which caused some problems as some systems were not able to handle that format very well.

There has however been some bits of progress, which are summarized in this post:Įven though Sound Manager support is still under development (with relatively good progress), the audio support for “Classic” type audio (that is, the emulation of audio hardware of Mac 128K through Plus/SE/Classic series machines) has been improved a bit. For the past half year progress has been a bit more slower than usually, mostly due to Toni being busy with the daily work, playing around on Twitch, and experimenting with his retro raycaster 3D engine prototype, while Pekka has been busy with work and private stuff.
