• id = audiodevinfo(io, name)

• id = audiodevinfo(io, rate, bits, channels)

• support = audiodevinfo(io, id, rate, bits, channels)

📥 Input argument

• io - input (1) or output (0) device

• id - an integer value.

• name - a string: name of the audio device to search.

• rate - a double scalar: sample rate.

• bits - an integer value: bits per sample.
