Inputs/Outputs

  • cpath.png path —

    path specifies the absolute path to the wave file.

    If the path is empty or invalid, the VI returns an error. The default is <Not A Path>.

  • cnclst.png sound format —

    sound format sets the sample rate, the number of channels, and the bits per sample for the wave file. The values for each of these controls is dependent on your sound card.

  • cdbl.png sample rate (S/s) —

    sample rate (S/s) sets the sampling rate for the wave file. Common rates are 44,100 S/s, 22,050 S/s, and 11,025 S/s. The default is 22050 S/s.

  • ci32.png number of channels —

    number of channels specifies the number of channels. This input can accept as many channels as the sound card supports. For most sound cards 1 is Mono and 2 is Stereo.

  • ci32.png bits per sample —

    bits per sample specifies the quality of each sample in bits. Common resolutions are 16 bits and 8 bits. The default is 16 bits.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • ibsrn.png sound file refnum —

    sound file refnum returns a reference to the sound file. You can pass sound file refnum to other Sound Files VIs.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
