PortAudio(DirectSound)で音が途切れる。 (2006-06-23 17:04 by Anonymous #23241)

出力方法をPortAudio(DirectSound)にした状態で
負荷が高いMIDIを再生すると音が途切れる。
Windows audio driverでは問題ありません。
仕様でしたらすいません。

この問題は認識してます。
PortAudioドライバーでは、再生の遅れを少なくする設定を選んであるため高負荷で途切れてしまいます。
再生の遅れを大きくすれば防げるはずなんですがそうするとリアルタイム性を損なうことになるため今の設定になってます。
ユーザーが再生の遅れを設定できるようにすればいいのですがTiMidity++のプログラムの構造上それはむずかしいです。

DirectSoundは設計上の都合で、高負荷なストリームを入力すると
バッファのエンドからスタートに移動するときに、大きな遅延が
必ず発生します。
