[PD] maximum of Oscillators

[David Sabine]

Hello,

It appears that oscillators can perform frequencies to 999999 hz and then
above 1000000 hz - but the accuracy of the wave forms at that frequency are
questionable as PD converts the numbers to 1.0000+e6 etc.  Certainly, the
resolution of waves above 999999 hz will be diminished?

This is obviously far beyond the human ear's audio range.

Also, depending on your sample rate, your audio hardware might be incapable
of producing frequencies above a certain range.  For example, the highest
frequency that a 44.100 khz sample rate can achieve is 22.05 khz.
Frequencies higher than that are either snipped entirely by your audio
hardware or appear as very low frequency artefacts.

Hardware that is capable of sampling audio at 192 khz have a maximum
frequency output of 96000 hz.

Regards,
Dave Sabine

hello List

1. question
is there someone who tried the maximum of oscillators pd can perform ?

2. question:
if i open a patch with an oscil i get this text.

#N canvas 16 64 314 182 10;
#X obj 66 54 osc~;
#X obj 109 54 osc~;
#X obj 66 86 *~ 0.1;
#X obj 66 121 dac~;
#X floatatom 66 19 5 0 0 0 - - -;
#X obj 109 33 + 5;
#X connect 0 0 2 0;
#X connect 1 0 2 0;
#X connect 2 0 3 0;
#X connect 2 0 3 1;
#X connect 4 0 0 0;
#X connect 4 0 5 1;
#X connect 5 0 1 0;

is there any systematic in the numbering of the boxes ?

Greetns
TOM
