1.3.2 Supported Data Formats on DM3 Boards

The CSP software supports the following encoding algorithms, sampling rates and sampling sizes for streaming on CSP channels using ec_stream( ) or ec_reciottdata( ) functions (WAVE or VOX file format with some exceptions):

• Mu-law PCM, 8 kHz sampling rate, 8-bit resolution (64 kbps)
• A-law PCM, 8 kHz sampling rate, 8-bit resolution (64 kbps)
• Linear PCM, 8 kHz sampling rate, 16-bit resolution little Endian and big Endian format
  (128 kbps) (VOX file format only)

Note: If you stream a file using an unsupported data format, CSP features are not available.

The CSP software supports the following encoding algorithms, sampling rates and sampling sizes for playing files during a CSP streaming session (WAVE or VOX file format):

• Mu-law PCM, 6 and 8 kHz sampling rate, 8-bit resolution (48 and 64 kbps)
• A-law PCM, 6 and 8 kHz sampling rate, 8-bit resolution (48 and 64 kbps)

Notes:

1. If you play a file using an unsupported data format while CSP streaming is occurring, CSP features are not available.

2. While CSP streaming is occurring on a channel, recording on this same voice channel is not supported.
