Using the MP3 compression option
The MP3 compression option lets you export sounds with MP3 compression. Use MP3 when you are exporting longer stream sounds such as music sound tracks.
If you are exporting a file that was imported in MP3 format, you can export the file using the same settings the file had on import.
- In the Sound Properties dialog box, select MP3 from the Compression menu.
- Select Use Imported MP3 Quality (the default setting). Deselect this option to select other MP3 compression settings, as defined in the procedure below.
- In the Sound Properties dialog box, select MP3 from the Compression menu.
- Deselect Use Imported MP3 Quality (the default setting).
- For Bit Rate, select an option to determine the bits per second in the exported sound file. Flash supports 8 Kbps through 160 Kbps CBR (constant bit rate). When you are exporting music, set the bit rate to 16 Kbps or higher for the best results.
- For Preprocessing, select Convert Stereo to Mono to convert mixed stereo sounds to mono (monaural). (Mono sounds are unaffected by this option.)
Note: The Preprocessing option is available only if you select a bit rate of 20 Kbps or higher.
- For Quality, select an option to determine the compression speed and sound quality:
Fast yields faster compression but lower sound quality.
Medium yields somewhat slower compression but higher sound quality.
Best yields the slowest compression and the highest sound quality.
