Appendix C: Export Audio Streams
The 'Export Audio Streams' command exports audio streams from a trace
file into two different file formats: RAW and WAVE.
The WAVE file format is Windows' native file format for storing digital
audio data. WAVE has become one of the most widely supported digital
audio file formats.
WAVE files use a standard structure called Resource Interchange File
Format (RIFF) that groups the files contents (sample format, digital audio
samples, etc.) into separate chunks, each containing it's own header and data
bytes. The chunk header specifies the type and size of the chunk data bytes.
1.3 File Structure
There are three chunks used for CATC WAVE file generated by the CATC
Bluetooth analyzer applications:
RIFF Chunk Type
Wave file headers follow the standard RIFF file format structure. The
format of interest here is "WAVE," which requires two sub-chunks" "fmt"
and "data."
Format Chunk - "fmt "
Describes the format of the sound info in data sub-chunk.
Data Chunk - "data"
The "data" sub-chunk Indicates the size of the sound information and
contains the raw sound data.
