Codec RECORD Audio Input Command Example:
C:\ Command Prompt
- ’ X
hdkcom.exe –port COM4 460800 –uart or –ppt –r 39 -record 20 rec.bit
where
-port COM4 is the PC’s COM port that the HDK communicates on as indicated by Windows
Device Manger
460800 is the baud rate of the PC connection
-ppt sets the HDK to use the PPT Interface of the AMBE-3000™ Vocoder chip
or
-uart sets the HDK to use the UART Interface of the AMBE-3000™ Vocoder chip
If neither –ppt or –uart is specified the PPT interface is used by default.
-r 39 is the rate index of the bit rate the file was originally encoded at. See Table 23 Standard
Rate Table for AMBE-3000. If it is desired to use rate words to set the rate – the format must be six
words in hex separated by a space as shown in the following example:
-r 0x0448 0x0766 0x0000 0x0000 0x0000 0x6848
-record 20 encodes the audio input for 20 seconds and saves it to a file
rec.bit is the name of the file to be encoded from the audio input
