<span class="sd"> Main processing audio loop callback handler.</span>
<span class="sd"> The Server object handles all communications with Portaudio and</span>
<span class="sd"> Portmidi. It keeps track of all audio streams created as well as</span>
<span class="sd"> connections between them.</span>
<span class="sd"> An instance of the Server must be booted before defining any</span>
<span class="sd"> signal processing chain.</span>
<span class="sd"> :Args:</span>
<span class="sd"> sr: int, optional</span>
<span class="sd"> Sampling rate used by Portaudio and the Server to compute samples.</span>
<span class="sd"> Defaults to 44100.</span>
<span class="sd"> nchnls: int, optional</span>
<span class="sd"> Number of output channels. The number of input channels will be the</span>
<span class="sd"> same if `ichnls` argument is not defined. Defaults to 2.</span>
<span class="sd"> buffersize: int, optional</span>
<span class="sd"> Number of samples that Portaudio will request from the callback loop.</span>
<span class="sd"> Defaults to 256.</span>
<span class="sd"> This value has an impact on CPU use (a small buffer size is harder</span>
<span class="sd"> to compute) and on the latency of the system.</span>
<span class="sd"> Latency is `buffer size / sampling rate` in seconds.</span>
<span class="sd"> duplex: int {0, 1}, optional</span>
<span class="sd"> Input - output mode. 0 is output only and 1 is both ways.</span>
<span class="sd"> Defaults to 1.</span>
<span class="sd"> audio: string {'portaudio', 'pa', 'jack', 'coreaudio', 'offline', 'offline_nb', 'embedded', 'manual'}, optional</span>
<span class="sd"> Audio backend to use. 'pa' is equivalent to 'portaudio'. Default is 'portaudio'.</span>
<span class="sd"> 'offline' save the audio output in a soundfile as fast as possible in blocking mode,</span>
<span class="sd"> ie. the main program doesn't respond until the end of the computation.</span>
<span class="sd"> 'offline_nb' save the audio output in a soundfile as fast as possible in non-blocking</span>
<span class="sd"> mode,</span>
<span class="sd"> ie. the computation is executed in a separated thread, allowing the program to</span>
<span class="sd"> respond while the computation goes on.</span>
<span class="sd"> It is the responsibility of the user to make sure that the program doesn't exit before</span>
<span class="sd"> the computation is done.</span>
<span class="sd"> 'embedded' should be used when pyo is embedded inside an host environment via its C api.</span>
<span class="sd"> If 'jack' is selected but jackd is not already started when the program is executed, pyo</span>
<span class="sd"> will ask jack to start in the background. Note that pyo never ask jack to close. It is</span>
<span class="sd"> the user's responsability to manage the audio configuration of its system.</span>
<span class="sd"> If 'manual' is selected, the server waits for a call to its `process` method to compute</span>
<span class="sd"> a single buffer size of audio samples. Successive calls to `process` can simulate a</span>
<span class="sd"> real computation (probably only useful in the context of internal testing).</span>
<span class="sd"> User can set an environment variable named PYO_SERVER_AUDIO to set this value globally.</span>
<span class="sd"> jackname: string, optional</span>
<span class="sd"> Name of jack client. Defaults to 'pyo'</span>
<span class="sd"> ichnls: int, optional</span>
<span class="sd"> Number of input channels if different of output channels. If None (default), ichnls = nchnls.</span>
<span class="sd"> winhost: string, optional</span>
<span class="sd"> Under Windows, pyo's Server will try to use the default devices of the given host.</span>
<span class="sd"> This behaviour can be changed with the SetXXXDevice methods. Defaults to "directsound".</span>
<span class="sd"> User can set an environment variable named PYO_SERVER_WINHOST to set this value globally.</span>
<span class="sd"> midi: string {'portmidi', 'pm', 'jack'}, optional</span>
<span class="sd"> Midi backend to use. 'pm' is equivalent to 'portmidi'. Default is 'portmidi'.</span>
<span class="sd"> If 'jack' is selected but jackd is not already started when the program is executed, pyo</span>
<span class="sd"> will ask jack to start in the background. Note that pyo never ask jack to close. It is</span>
<span class="sd"> the user's responsability to manage the audio/midi configuration of its system.</span>
<span class="sd"> User can set an environment variable named PYO_SERVER_MIDI to set this value globally.</span>
<span class="sd"> verbosity: int, optional</span>
<span class="sd"> Set the server's verbosity.</span>
<span class="sd"> .. note::</span>
<span class="sd"> The following methods must be called **before** booting the server</span>
<span class="sd"> - setInOutDevice(x): Set both input and output devices. See `pa_list_devices()`.</span>
<span class="sd"> - setInputDevice(x): Set the audio input device number. See `pa_list_devices()`.</span>
<span class="sd"> - setOutputDevice(x): Set the audio output device number. See `pa_list_devices()`.</span>
<span class="sd"> - setInputOffset(x): Set the first physical input channel.</span>
<span class="sd"> - setOutputOffset(x): Set the first physical output channel.</span>
<span class="sd"> - setInOutOffset(x): Set the first physical input and output channels.</span>
<span class="sd"> - setMidiInputDevice(x): Set the MIDI input device number. See `pm_list_devices()`.</span>
<span class="sd"> - setMidiOutputDevice(x): Set the MIDI output device number. See `pm_list_devices()`.</span>
<span class="sd"> - setSamplingRate(x): Set the sampling rate used by the server.</span>
<span class="sd"> - setBufferSize(x): Set the buffer size used by the server.</span>
<span class="sd"> - setNchnls(x): Set the number of output (and input if `ichnls` = None) channels used by the server.</span>
<span class="sd"> - setIchnls(x): Set the number of input channels (if different of output channels) used by the server.</span>
<span class="sd"> - setDuplex(x): Set the duplex mode used by the server.</span>
<span class="sd"> - setVerbosity(x): Set the server's verbosity.</span>
<span class="sd"> - reinit(sr, nchnls, buffersize, duplex, audio, jackname): Reinit the server's settings.</span>
<span class="sd"> - deactivateMidi(): Deactivate Midi callback.</span>
<span class="sd"> - setIsJackTransportSlave(x): Set if pyo's server is slave to jack transport or not.</span>
<span class="sd"> - allowMicrosoftMidiDevices(): Allows the Microsoft Midi Mapper or GS Wavetable Synth devices.</span>
