-#X text 12 24 SAMPLE RATE;
-#X text 29 46 [adc~] and [dac~] always operate at the sample rate that
-is specified in PD's command line. By default \, the sample rate is
-44100 hz. But PD operates any sample rate supported by standard audio
-hardware. 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 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. 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 text 21 15 -NODAC and -NOADC;
-#X text 26 37 There may be cases when you do not want PD to send or
-receive audio signal with your soundcard. You can manually disable
-the [dac~] and [adc~] objects separately using the "-nodac" and "-noadc"
-switch \, or disable both using the "-nosound" switch.;

-#X text 30 47 PURPOSE:;
-#X text 104 47 [adc~] and [dac~] provide real-time audio input and
-output for PD \, respectively \, whether analog or digital.;
-#X text 152 541 - Dave Sabine \, May 5 \, 2003;
-#X text 104 83 Both of these objects accept arguments (numbers) which
-indicate which audio channels are to be used by PD. By default \, these
-objects are stereo and communicate on audio channels 1 and 2 (left
-and right respectively) but by using arguments \, other channel numbers
-can be specified. These objects can communicate with hundreds of audio
-channels \, but you are likely limited by your audio hardware to 2
-\, 4 \, 6 \, 8 \, 12 \, 16 \, 32 \, 64 \, etc.;

-\, but channel numbers that out of range will be dropped by [dac~]
-or appears as zero by [adc~].;
