Inputs/Outputs

  • cbsrn.png sound file refnum —

    sound file refnum is the reference to the sound file.

    You generate sound file refnum with the Sound File Open VI.

  • 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 out —

    sound file refnum out is the reference to the sound file originally passed in the sound file refnum parameter.

  • iu32.png total number of samples/ch —

    total number of samples/ch returns the total number of samples per channel in the wave file.

  • inclst.png sound format —

    sound format returns the sample rate, the number of channels, and the number of bits per sample in the wave file.

  • idbl.png sample rate (S/s) —

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

  • ii32.png number of channels —

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

  • ii32.png bits per sample —

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

  • ierrcodeclst.png error out —

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