Note that in most desktop systems this is actually managed by PipeWire or PulseAudio, to check this, you can execute arecord -L | grep -A1 ^default. On Linux, the device is selected via ALSA, typical choices include:
#Audiodevice examples processing pro#
Spectrum_inversion.py -I "MacBook Pro Microphone" Since most such device names contain spaces, make sure to put quotes around the name argument, for example: The listings under "Name" contain the exact device names currently available if a new audio source is attached to the computer then a new name will appear - for example "Line In" for some Macs. To see or change the current device, go into the System Preferences, click on "Sound", and then the "Input" tab.
Once the application has permission, leaving the 'Device Name' blank will connect to the current default audio input device. For example, if you are launching GNU Radio Companion from the iTerm command line, go to System Preferences -> Security & Privacy -> Privacy -> Microphone and check the box for "iTerm2". On OSX, Audio Sink will return only zeros unless the GNU Radio binary is launched from an application that has been granted permission to use the microphone. Leave the device name blank to choose the default audio device. For typical applications, this should be set to 48kHz. Note: not all sampling rates will be supported by your hardware. To set the Audio sampling rate, click the drop-down menu to see popular rates.
