Dialog Reference
Missing Plug-ins dialog
This dialog appears if you open a project that references plug-ins that are
not installed on your machine. If you save the project after you have
opened it with missing plug-ins, all references to missing plug-ins are
lost. To retain the missing plug-ins in your project, exit SONAR without
saving, reinstall the missing plug-ins and then re-open the project.
MP3 Export Options dialog
The following is a description of the options in the MP3 Export Options
dialog:
Bit Rate
Choose a bit rate from the drop-down list. A higher bit rate creates larger,
higher quality files. The Bit Rate allows you to select the trade-off between
the size and the sound quality of the compressed file. Compressing to
higher bit rates will provide better sound quality, but will also create larger
files.
Bit rate is specified in bits per second. As a rule of thumb, bit rates of
120,000 bits per second or higher offer near CD quality sound. Lower bit
rates can be used, with a corresponding decrease in quality. If you are
preparing your project for distribution on the web, lower bit rates will create
smaller files, and therefore faster downloading time.
The maximum bit rate that you can select depends on the sampling rate of
the project. The encoder supports bit rates up to 320000 bit per second,
providing extremely high quality compression. Selection of 320000 bits per
second or lower requires that your project was created using at least a 32
kHz sampling rate. If your project was created using a lower sampling rate,
your selection of bit rates will also be limited.
Stereo Mode
Select one of the following from the drop-down list:
• Joint Stereo—In Joint Stereo mode, the encoder optimizes the stereo
encoding by comparing the two stereo channels. If similar information
is found in the left and right channels, the encoder uses the similar
information to minimize the data it stores in the MP3 file. While this
encoding technique may result in better compression, it may result in a
loss of stereo quality. An additional option when using Joint Stereo
compression is the selection of Intensity Stereo. Selection of Intensity
Stereo instructs the encoder to further optimize the encoding by
