MicroKey/Audio Port and Sound Recorder


The information in this article applies to:

  • Microsoft Windows versions 3.1, 3.11


MicroKey/Audio Port is an external sound adapter manufactured by Video Associates Labs that allows you to record and play high-quality digital audio (wave and vocal files) through a parallel port.

Sound Recorder can be used to play and record wave (.WAV) files through MicroKey/AudioPort.


Sound Recorder can play all standard Wave files formats, as well as the MicroKey/AudioPort ADPCM 4-bit compressed format. However, it does not provide a means for selecting which format to record.

By default, the Sound Recorder records audio files at 22kHz, 16 bits when used with the MicroKey/AudioPort. If recording audio using different formats is desired, do the following:

  1. Copy the set of record template files from the MicroKey/AudioPort Windows Disk 1 to a subdirectory on the hard drive. These files are all in the form


    where "ss" indicates the sample rate and "bb" indicates the sample size. To copy these files to the Windows directory, type:

    copy a:\rec*.wav c:\windows

  2. Start Sound Recorder and choose Option from the File menu. Select the directory where the record template files are stored and select the template file that matches the sample rate and size.
  3. Record the desired audio.
  4. From the File menu, choose Save As to store the audio segment to a file. The audio will be saved in the same format as that of the loaded record template file.

Files recorded using the compressed (*M4.WAV) format are compatible only with MicroKey/AudioPort. It may be unlikely that other audio products will play these files.

The template files are write-protected to prevent accidental erasure. To remove the files from the hard drive, change the read-only attributes associated with each file.

For further information, contact Video Associates Labs (VAL).
