Sample rates cannot be changed at run-time in PD \, but must -be stated in the command line when PD is instantiated. As well \, two -or more instances of PD running simoultaneously can each be using different -sample rates! Having said that \, PD can easily upsample or downsample -by using the [block~] object. Here are some example of the common sample -rates:; -#X text 85 232 c:/pd/bin/pd.exe -r 11025; -#X text 85 262 c:/pd/bin/pd.exe -r 22050; -#X text 86 329 c:/pd/bin/pd.exe -r 88200; -#X text 85 217 c:/pd/bin/pd.exe -r 8000; -#X text 85 247 c:/pd/bin/pd.exe -r 16000; -#X text 86 278 c:/pd/bin/pd.exe -r 32000; -#X text 86 294 c:/pd/bin/pd.exe -r 44100 CD Quality; -#X text 86 311 c:/pd/bin/pd.exe -r 48000 DAT Quality; -#X text 87 366 c:/pd/bin/pd.exe -r 192000 DVD-Audio Quality; -#X text 86 347 c:/pd/bin/pd.exe -r 96000 DVD-Video/Audio Quality; -#X restore 40 75 pd sample_rate; -#N canvas 131 31 564 558 multi-channel_audio 0; -#X text 16 13 MULTI-CHANNEL AUDIO; -#X text 32 40 All sound cards are capable of at least two channels -of audio. 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.
