222 CHAPTER 12 Options Menu - Edit View • Peaks Cache: This value determines the number of samples per block to be used when storing peak files. Larger values will reduce the RAM requirement for large files at the expense of slightly slower drawing at some zoom levels. If RAM is an issue on your system, and you're working with very large files (several hundred megabytes or more in size), you should consider increasing the Peaks Cache to 1024 or even 1536 or 2048. • Save Peak Cache Files: If this option is enabled, all .wav files will have peak files saved with them (in the same folder) with the extension .pk following the original audio filename. Uncheck this box if you don't want Adobe Audition to save peak files on your hard drive. • Rebuild Wave Display Now: Press this button to have Adobe Audition rescan the current file for sample amplitudes and redraw the waveform. Data Tab The controls in this area of the Settings dialog have to do with the way Adobe Audition handles audio data. The Data Tab of the Settings Dialog Auto-convert all data to 32-bit upon opening If this item is checked, all 8-bit and 16-bit data is automatically converted to 32-bit when a file is loaded, and all subsequent operations will keep the data in the 32-bit realm. Interpret 32-bit PCM .wav files as 16.8 float (compatibility with old Cool Edit format) Checking this option causes this version of Adobe Audition to be compatible with previous versions when it comes to handling 32-bit PCM .wav files. [[how should we handle reference above to Cool Edit?-GS]]
