USING SOUNDBOOTH CS4 75 Saving audio and video files Windows Media Video (.wmv) The Windows version of Soundbooth supports Windows Media Video, Microsoft's format for compressed, streaming video. Typically, WMV files are viewed in Windows Media Player, but other applications and plug-ins also support this format. Though the formats above are primarily used for video output, you can specify audio-only output in the Export Settings dialog box. See also "Options for video and AAC formats" on page 76 Options for standard audio formats ASND options In the Adobe Sound Documents section of the Preferences dialog box, the following settings apply to newly created files. (To change these settings for an existing ASND file, open it, and choose File > Adobe Sound Document Settings.) Multitrack Time Display For new multitrack files, determines the time range initially visible in the Editor panel. Embedded Mixdown Determines the audio quality of ASND files in other Adobe applications. Either select Flash Compatible, or select Custom and specify a sample rate and bit depth appropriate for your video projects. (See "Understanding sample rate" on page 8 and "Understanding bit depth" on page 9.)

This dialog box provides a compact group of settings that you can quickly optimize. General options File Type Indicates the file format. Range Specifies whether to save the entire file or the currently selected range. Add To Files Panel Adds the saved file to the Files panel. Audio options Compressor Specifies the audio codec, if any. The codecs available depend on the platform and file format. In Mac OS, only the Uncompressed option is available. In Windows, WAV format provides these additional options: • IMA ADPCM Compresses 16-bit audio to 4-bit. This compression scheme can be a good alternative to MPEG-1; it provides fairly fast decoding and degrades audio quality only slightly. • Microsoft ADPCM Compresses 16-bit audio to 4-bit using a slower method than IMA ADPCM, but quality can be superior, depending upon audio content. • CCITT A-Law Compresses 16-bit audio to 8-bit, but produces dynamic range equivalent to13 bits (78 dB). This compression scheme is the standard for European telephone systems. Updated 15 July 2009
