    • In a music video game, a player's performance is digitally sampled while the player performs a musical composition. The player's performance is compared with a reference performance of the musical composition provided by the music video game. Performance feedback is presented to the player based on the results of the comparison. In some embodiments, sample times associated with digital samples of the player's live vocal performance are compared against timestamps of data records embedded or otherwise accompanying the reference performance audio track. Pitch and rhythm information is retrieved from the data record having a timestamp that most closely matches the sample time of interest. The pitch and rhythm data is used to compute pitch and rhythm errors, which are used to generate performance evaluation data. The performance evaluation data is used to present performance feedback to the player while the player is performing the musical composition.
    • 在音乐视频游戏中,玩家的演奏被数字采样,而玩家执行音乐作品。 玩家的表现与由音乐视频游戏提供的音乐作品的参考表演进行比较。 根据比较结果向玩家提供性能反馈。 在一些实施例中,将与玩家的实时声乐表演的数字样本相关联的采样时间与嵌入的或附带的参考演奏音轨的数据记录的时间戳进行比较。 从具有与感兴趣的采样时间最接近的时间戳的数据记录中检索音调和节奏信息。 音调和节奏数据用于计算音高和节奏错误,用于产生性能评估数据。 性能评估数据用于在播放器执行音乐作品时向玩家呈现性能反馈。
