HARK Document Version 2.1.0. (Revision: 7522) : Sound recording test of the 16ADUSB in HARK

8.3.3 Sound recording test of the 16ADUSB in HARK

Prior to sound recording, confirm the devices to be used (Table 8.5) are operable.

Table 8.5: List of device to be used

Device name	Description
TD-BD-16ADUSB	A/D, D/A conversion device
PC	PC to operate TD-BD-16ADUSB chastity

For the sound recording test for HARK, change only the property of each module with the network file test.n the same as that shown in Figure 8.2. Table 8.6 shows the settings for each property.

$>$ ./test.n

By entering the above, speech of the analog input 1 of 16ADUSB is recorded for three seconds. The speech of the PCM 16-bit quantization and 16 kHz sampling are saved in the little endian RAW format.
