devinfo = audiodevinfo
devs = audiodevinfo(IO)
name = audiodevinfo(IO, ID)
ID = audiodevinfo(IO, name)
DriverVersion = audiodevinfo(IO, ID, 'DriverVersion')
ID = audiodevinfo(IO, rate, bits, chans)
doesSupport = audiodevinfo(IO, ID, rate, bits, chans)
devinfo = audiodevinfo returns a structure, devinfo, containing two fields, input and output. Each field is an array of structures, with each structure containing information about one of the audio input or output devices on the system. The individual device structure fields are:
Name — A string indicating the name of the device.
DriverVersion — A string indicating the version of the installed device driver.
ID — The ID of the device.
devs = audiodevinfo(IO) returns the number of input or output audio devices on the system. Use an IO value of 1 to indicate input, and an IO value of 0 to indicate output.
name = audiodevinfo(IO, ID) returns the name of the input or output audio device identified by device ID.
ID = audiodevinfo(IO, name) returns the device ID of the input or output audio device identified by the given name (partial matching, case sensitive). If no audio device is found with the given name, -1 is returned.
DriverVersion = audiodevinfo(IO, ID, 'DriverVersion') returns a string indicating the driver version of the specified audio input or output device.
ID = audiodevinfo(IO, rate, bits, chans) returns the device ID of the first input or output device that supports the sample rate, number of bits, and number of channels specified by the values of rate, bits, and chans, respectively. If no supporting device is found, -1 is returned.
doesSupport = audiodevinfo(IO, ID, rate, bits, chans) returns 1 or 0 for whether or not the input or output audio device specified by ID can support the given sample rate, number of bits, and number of channels.
