statistics about WAVE sinus cycle durations...

Post by jedie »

I have added a analyze function in PyDC, to display zeror crossing timings in wave files (See: viewtopic.php?f=8&t=4231&p=8980#p8980 )

Here i will post some statistics about wave files from http://archive.worldofdragon.org/archiv ... ragon/wav/

DRAGONDATA_DRAGONSELECTION4.WAV

Code: Select all

Python dragon 32 converter 0.1.0.dev
-------------------------------------------------------------------------------

source file.......: DRAGONDATA_DRAGONSELECTION4.WAV
open wave file 'DRAGONDATA_DRAGONSELECTION4.WAV'...
Framerate: 44100
Number of audio frames: 9797790
channels: 1
samplewidth: 1 (8Bit wave file)
the max volume value is: 255
Ignore sample lower than 5.0% = 12

100.0% wav pos:3.7 min (frame no.: 9797790) - eta: 0.0 ms (rate: 32671Frames/sec)        

Found this zeror crossing timings in the wave file:

 1002Hz (   22 Samples) exist: 173446 *****************************************
 1050Hz (   21 Samples) exist: 173446 *****************************************
 2005Hz (   11 Samples) exist: 212689 **************************************************

Notes:
 - Hz values are converted to full sinus cycle duration.
 - Sample cound is from half sinus cycle.
Seems that this is a very clean WAVE.

For compare:

HelloWorld1 origin.wav have i digitized from my Dragon 32:

Code: Select all

source file.......: test_files/HelloWorld1 origin.wav
open wave file 'test_files/HelloWorld1 origin.wav'...
Framerate: 44100
Number of audio frames: 109923
channels: 1
samplewidth: 2 (16Bit wave file)
the max volume value is: 32768
Ignore sample lower than 5.0% = 1638

100.0% wav pos:2.5 sec (frame no.: 109923) - eta: 0.0 ms (rate: 34408Frames/sec)
