audiodevinfo

Get audio devices information.

Syntax

• devices = audiodevinfo()
• devices = audiodevinfo('default')
• devices = audiodevinfo(io)
• name = audiodevinfo(io, id)
• 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.
• channels - an integer value: number of audio channel.

Output argument

• devices - struct array
• name - a string: name of the audio device specified by io and id.
• id - an integer value.
• support - a logical: true if values supported or false.

Description

audiodevinfo returns a structure with available audio input and output devices.

devices = audiodevinfo('default') returns a structure with default used audio input and output devices.

Example

info = audiodevinfo()
OUTPUT_DEVICE = 0;
INPUT_DEVICE = 1;
for k = [1:audiodevinfo(OUTPUT_DEVICE)]
  info.output(k)
end
for k = [1:audiodevinfo(INPUT_DEVICE)]
  info.output(k)
end
