I'm working on a simple musical instrument tuner in Ruby (2.0.0) using GTK. When it comes to audio playback though, I don't know where to start looking for a suitable gem. Any recommendations? My idea was to package audio files of the 12 notes of the chromatic scale, but I can't seem to find audio samples of these.

I should also say that I'd much prefer if it was cross-platform!

不确定它可以帮助你，但我遇到的唯一一个是这个 它基于libsndfile

您可能还想在 SouceForge 上使用 GTK 查看这个简单的音频播放器。
