Hi @hajimehoshi , I am trying to use your mp3 library here https://github.com/gen2brain/malgo/blob/master/examples/playback/playback.go , it works on Linux but on macOS ( I am trying in vmware, don't have real hardware :( ) it sounds like 2x or 3x slower. Do you think something can work differently on macOS? It can be anything really, I am working on https://github.com/dr-soft/mini_al bindings for Go, but I can play wav on macOS with same example, and mp3 works on Linux, but on macOS there is an issue. I thought at first that there is an issue with OpenAL backend, but if I force OpenAL on Linux instead of alsa, again mp3 sounds ok.
go-mp3 should work on macOS. Decoding is completely device-independent. I guess there is a problem how to specify sampling rate. Is the sample rate of MP3 same as the sample rate that are specified at your backend?
btw. https://github.com/dr-soft/mini_al looks great and is in active development, perhaps your oto player can benefit from that library, my bindings are low level, I didn't figure out how I can implement reader/writer. Single header library, public domain, with plan to support CoreAudio and iOS :)
Thanks but I'm not sure what kind of benefit oto would get. oto is in pure Go on Windows, so C library is not available there.
