The audio import script will automatically -select gr.audio_osx if it is available (though it will try to import -ALSA first, then OSS, then OSX, and finally WINDOWS audio modules, in -that order). If that import command doesn't work, try reinstalling -gnuradio-core from scratch followed by gr-audio-osx. - -2) Instantiation arguments for either source or sink are: - -* sample_rate : integer : default == 44100 - OSX converts the integer sample rate to a double internally; it - would be nice to have this input as a double natively, but that - doesn't work with other audio devices. - -* device_name : string : default == "2" - For OSX, the device name should be an integer string. This value is - the maximum number of channels to allocate (for input or output). - In the "source" case (input), the actual number of channels will be - whatever is available on that current system input device. In the - "sink" case (output), OSX will convert the provided channels into - whatever format is required by the current system output device. - For example, "3" would try to setup for 3 input or output channels. - NOTE that this is a very different use than that for other audio - modules (though they can interpret the number of channels from this - argument). - -* do_block : boolean : default == true - If the data transfer buffer between OSX internals and GNURadio gets - full, either block (true) or overwrite (false) depending on this - variable. - -The following are currently non-standard arguments: - -* channel_config : integer : default == -1 - An enum (internally) describing the channel configuration. Not - currently used, but rather reserved for future expansion. - -* max_sample_count : integer : default == -1 - The maximum number of samples to buffer between OSX internals and - GNURadio. The value -1 is mapped to 1 second's worth of data. - -3) When the buffer is full and do_block is false and new data comes -in, the oldest data will be overwritten. The source will print out -"iX" each time this happens; the sink will print out "oX". - -4) In the "src" directory is a python script "test_audio_loop" which -connects the default audio input device to the default audio output -device. This script is very useful in testing that audio is correctly -installed and both the source and sink are functional. This script is -not run by "make check". |
