    • Techniques are presented for dynamically controlling an audio crossfade from a first audio track to a second audio track. The first audio track may be decoded and buffered to a first buffer. A user may select a second audio track at some point during playback of the first audio track. The second audio track may be decoded, and a processor may access the decoded second audio track and the buffered first audio track and mix the two audio tracks. The mixed audio track may be inserted in the same first buffer near or at the read pointer of the first buffer, such that latency between the user selection and the crossfade into the selected audio track may be minimized. The insertion of the mixed audio track may depend on various factors, including the type of audio file and/or the decoder type used to decode the second audio track.
    • 提供了用于动态地控制从第一音频轨道到第二音频轨道的音频交叉渐变的技术。 第一音频轨道可以被解码并缓冲到第一缓冲器。 用户可以在第一音轨的播放期间的某一点选择第二音轨。 第二音频轨道可以被解码,并且处理器可以访问经解码的第二音频轨道和缓冲的第一音频轨道并混合两个音频轨道。 混合音频轨道可以被插入在第一缓冲器的读指针附近或其附近的相同的第一缓冲器中,使得用户选择和与所选音轨之间的交叉渐变的等待时间可以被最小化。 混合音轨的插入可以取决于各种因素,包括音频文件的类型和/或用于解码第二音轨的解码器类型。

    • A key sprocket drive system for a conveyor belt having a drive drum having an outer surface. The outer surface of the drive drum is adapted to engage a securement means. A contoured collar has an inner surface and an outer surface. The contoured collar is adapted to receive the securement means and adapted to engage the outer surface of the drive drum at predetermined positions therefore providing defined gaps between the inner surface of the contoured collar and the outer surface of the drive drum. The key sprocket drive system further comprises a sprocket member having a generally annular configuration with externally facing teeth-like protrusions at spaced intervals. The sprocket member is adapted to receive the securement means whereby the securement means engage the sprocket member and the contoured collar to secure the sprocket member and the contoured collar to the drive drum. The teeth-like protrusions engage the conveyor belt so as to drive the conveyor belt.
    • 一种用于传送带的关键链轮驱动系统,具有具有外表面的驱动滚筒。 驱动滚筒的外表面适于接合固定装置。 轮廓轴环具有内表面和外表面。 轮廓轴环适于接收固定装置并且适于将驱动滚筒的外表面接合在预定位置,从而在轮廓轴环的内表面和驱动滚筒的外表面之间提供限定的间隙。 关键链轮驱动系统还包括具有大致环形构造的链轮构件,其间隔开间隔地具有外表面的齿状突起。 链轮构件适于接收固定装置,由此固定装置接合链轮构件和成形的套环,以将链轮构件和轮廓的套环固定到驱动鼓。 齿状突起与传送带接合以驱动传送带。
