Hi,
Anyone have experience with audio waveform drawing?
Currently what i've done:
I have a 512 pixels wide picture.
i divide the PCM data to 512 blocks, and from each block i count the
average (i also tested maximum)
However, this doesn't draw correct waveform display, when compared to
pro sound editors.
Any ideas?
Regards,
Aleksi Strandberg
Aleksi:
As sound intesity measures are non-linear you may need a non-linear
average. A good place to start might be an RMS average.
Good luck.
