File Format Plug-ins
GoldWave supports external file format plug-ins for opening and saving files. These plug-ins are created by other developers by using the GoldWave Plug-in Development Kit to handle file types that GoldWave does not support directly.
GoldWave checks for new plug-ins only during startup, so if a new plug-in is installed, you must restart GoldWave for it to be detected.
Use Options | File Formats to enable and disable plug-ins or to change the order in which they are used.
When you open a file in GoldWave, these steps are followed:
- If the file type is a CD audio (CDA) track, you are advised to use the CD Reader tool and no further processing occurs.
- For all other file types, the file is passed to each file format plug-in module until one is able to handle the file. The order is configured under the File Plug-in Precedence tab of the File Format Options window.
- If none of the plug-ins support the file format, then the Undetectable Types list under the File Format Options window is used to determine if type and attributes have been associated with the file type. If so, the file is open automatically using those attributes.
- If there are no associations, then the File Format window is displayed so that the attributes can be specified manually. Chances are that compressed files cannot be open and decoded properly unless a new plug-in is installed for that file type.
MP3 Settings
- Custom button in the Default Save Format tab of Options | File Formats with the MP3 file type selected.
- Custom button in the Convert tab of Batch Processing with the MP3 file type selected.
- Custom button in the Select Audio Attributes window with the MP3 file type selected.
Use these settings to set MP3 related attributes directly.
| MP3 Settings | |
|---|---|
| Setting | Description |
| VBR quality | Uses a variable bitrate (VBR) when encoding the file. Use Bitrate range to set the minimum and maximum bitrates specified. The range of available bitrates depends on the sampling rate. Selecting a lower or higher sampling rate lists lower and higher ranges of available bitrates.
Set it to Off to use a constant birate. |
| Channels | Sets the number of channels in the file and how stereo encoding is handled. Use Mono to create a single channel file. The other options create a stereo file. Use Stereo to create a typical stereo file. Use Joint Stereo to get better compression when the left and right channels contain similar audio. Use Dual Channnel when the left and right channels contain completely different audio. |
| MPEG bits | Sets bits in the MPEG header. Include CRC tells the encoder to include CRC data after the header. Copyright means the audio is copyrighted. Original means the audio is new or original material. |
