BitsPerSample (Data Acquisition Toolbox)

Specify the number of bits the sound card uses to represent each sample

Description

BitsPerSample can be 8, 16, or any value between 17 and 32. The specified number of bits determines the number of unique values a sample can take on. For example, if BitsPerSample is 8, the sound card represents each sample with 8 bits. This means that each sample is represented by a number between 0 and 255. If BitsPerSample is 16, the sound card represents each sample with 16 bits. This means that each sample is represented by a number between 0 and 65,535.

For older Sound Blaster cards configured for full duplex operation, you might not be able to set BitsPerSample to 16 bits for both the analog input and analog output subsystems. Instead, you need to set one subsystem for 8 bits, and the other subsystem for 16 bits.

Note To use the high-resolution (greater than 16 bit) capabilities for some sound cards, you might need to configure BitsPerSample to either 24 or 32 even if your device does not use that number of bits.
