iphoneピアノアプリだが、遊びの注意点として期待

Question

Im作ピアノの試験アプリでは、すべてのキーボードが響くその後のがんに使用ガレージバンドが、今ではもうほとんどの問題点:

の注記は5秒間長(最小時にガレージバンド)ので、ご注意できないはずはないので、いまで待たなければならない実際のご注意約1秒の音、そして静寂の約4秒 のものであり注意を再生することはできませんし、 Im用AVFoundation.の枠組み,

• しAudioToolbox.枠組みが、この問題は私4.1ipod touch（のだ。) がシミュレーター様

• 私も確認OpenAL、ObjectALもう少しくだけゲノ??

こちらのコード

 #import "pianoViewController.h"

 @implementation pianoViewController

そしてもらえると助かりますように利用できまAVFoundation遊び、複数のノート早いのでは？（ほぼ重なるようにAudioToolbox) やったらいいですか？

感謝です。

Answer 1

の代わりにシュー-ホーニングでしょうがな問題であることなくご使用になることもオーディオ編集ソフトウェアがついていない最小限のトラックの長さにしました。

その一つの例では、Macに対応や無料、Audacity: http://audacity.sourceforge.net/

また、OpenALにぴったり遊んでく短音、潜在的に重なる.できる思いますので32の再生を一度に適用されています。
