The Audio Conversion Wizard allows you to convert 8kHz 16-bit PCM_SIGNED
audio format to 8kHz 8-bit u-law audio format and 8kHz 8-bit audio format
to 8kHz 16-bit PCM_SIGNED wave audio format. It allows you to convert multiple
files simultaneously and to select the file extension for your converted files.
The converted files are created and stored in a Converted Files folder
in the same project as the source file.
You can start the wizard from either the pop-up menu of an audio file in
the Navigator view, or from the Run menu.
To convert an audio file, do the following:
- Start the wizard by doing one of the following:
- Click Run > Audio Conversion.
- Right-click an audio file in the Navigator view and select Audio
Conversion.
- In the Welcome window, click Next to continue.
- Select the files you want to convert from the list of files shown.
- Files with the .au extension can be either 8Khz 16-bit PCM or 8Khz 8-bit
mu-law headered files.
- Files with the .ulw or .vox extension are expected to be 8Khz 8-bit mu-law
headerless files.
- Files with the .wav extension are expected to be 8Khz 16-bit PCM.
Note: Filter the files to choose from by file type. For example, you
can filter by the following supported file types: .wav, .au, .vox, and .ulw
- Select Next.
- In the Select Conversion Method window, select the method of conversion,
to u-law or to wave, and click Next. If necessary,
click Back to go back and review your file choices.
- If convert to u-law is selected, the output is 8kHz 8-bit mu-law files.
- If convert to wave is selected, the output is 8kHz 16-bit PCM files.
- In the Select File Extension window, select the file extension for the
converted file and click Next.
- If convert to u-law is selected, .vox and .ulw files are headerless and
.au files are headered.
- If convert to wav is selected, .wav files are headered.
- In the Summary of Files window, click Next to convert
your selected files.
- The Conversion Complete window displays a summary of the conversion results.

Note: If you selected an audio file that is not in the expected format, 8kHz,
16-bit PCM_SIGNED or 8kHz 8-bit headerless audio format, conversion does not
occur and an error message is displayed.
