PD supports these two channels by default and uses your system's +generic audio drivers to communicate with your hardware. However \, +for faster input/output and for more than two channels of audio \, +PD incorporates the use of "PortAudio" which uses ASIO drivers to communicate +with your hardware. So \, to instruct PD to use more than two channels +of audio \, your command line should read like below:; +#X text 93 182 c:/pd/bin/pd.exe -pa -inchannels 8 -outchannels 8; +#X text 32 211 The "-pa" switch means "PortAudio". This switch is new +as of PD version 0.37 TEST 4 and replaces the old "-asio" switch.; +#X text 32 271 The "-inchannels" and "-outchannels" switches can be +summarized by using "-channels 8" because currently PortAudio requires +that the number of incoming and outgoing channels must be equal. This +may change in the PD's future...; +#X text 32 361 To further optimize PD's usage of your audio hardware +\, you can explore the following:; +#X text 42 402 - audiobuf; +#X text 43 420 - blocksize; +#X text 42 436 - audioindev; +#X text 42 454 - audiooutdev; +#X text 38 480 With the right hardware \, PD can manage audio input +and output with lower than 10 milliseconds of latency.; +#X restore 104 514 pd More_Info; +#N canvas 85 2 395 244 Related_Objects 0; +#X text 25 8 Native PD Objects; +#X text 25 92 Externals and other object libraries; +#X obj 45 46 dac~; +#X obj 98 46 switch~; +#X obj 171 46 block~; +#X restore 104 488 pd Related_Objects; +#X text 16 107 ARGUMENTS:; +#X text 32 188 OUTLETS:; +#X text 23 344 EXAMPLES:; +#X text 20 487 SEE ALSO:; +#X obj 33 20 adc~; +#X text 30 53 PURPOSE:; +#X text 108 18 - AUDIO INPUT: ANALOG/DIGITAL CONVERTER SIGNAL; +#X text 152 541 - Dave Sabine \, May 6 \, 2003; +#X text 104 53 [adc~] is an acronym meaning "Analog/Digital Converter +Signal" and is PD's interface to access the audio information arriving +at your soundcard(s).; +#X text 106 106 The object defaults to 2 incoming audio channels (usually +a left and right stereo pair).
