Hello JCappa2:
Here is some detailed background info of using Audio with Combustion verison 1----
(Note: this also applies to Combustion Version 2, but with some minor additions and details. See your Combustion V2 User guide for more info.)
As you may already know, Combustion supports two standard Audio File Types: WAV (for uncompressed Microsoft audio) and AIFF (for uncompressed Macintosh audio). Combustion also supports audio files that are embedded in Video for Windows (AVI) or QuickTime movies (MOV). When the audio file is loaded, the audio is copied to the workspace and cached to RAM. As for the Supported Sampling Rates, Combustion supports most audio sampling rates and bit depths: You can use 8- or 16-bit audio, and sampling rates from 1 KHz up to 48 KHz. Note: 44.1 KHz is considered "standard," as this rate corresponds to CD sampling rates. 48 KHz is frequently used with editing systems, as it is the standard with SDI (Serial Digital Interface Video) and is also the standard for DAT recording.
When you load an audio file into your workspace, it is automatically cached to RAM. However, synchronized playback of both audio and video from the RAM cache is dependent on your system
