Follow-up Comment #4, bug #49927 (project octave):
3 remarks:
1. I thought, I had installed the 64-Bit version.
At least there are many references to i686-w64-mingw32 . Or does this mean
something else ? Octave does not tell me whether it is 32 or 64 Bits. How can
I check this ?
2. I am not trying to read a 700 MB WAV-file.
I am just reading 4k sample blocks (16k bytes) always into the same data
array, processing them and writing to a new file.
I don't see any need for allocation of several hundert MByte of memory. I
hope, audioread does not do such a nonsense, when I am trying to read 16 kByte
at file position 16.xxx.xxx.
On the other hand it was possible to read that block after a restart.
3. (Almost) the same code runs without any problems on an old Windows XP (32
Bit) Laptop with MATLAB 6.1 from 2001.
( and by the way much faster although it is just a 2GHz Pentium, while the PC
running Octave is a Quadcore i5-3570 at almost 4 GHz.)
So to repeat once more, the data size read is a mere
size = 4096 * 4 = 16 kByte !
