Hi Klas,
It could be, that the problem was the large file size caused by your
extremely long recording session. Generally, there is a limitation
in the maximum file size that can be saved onto disk. This is a
limitation of both the sound file format and the file system (FAT)
of your harddisk. For example, common .wav files are limited to a
maximum file size of 2 GB. But six hours of uncompressed stereo,
sampled at 44.1 kHz would require 3.5 GB. Perhaps, your software was
not prepared to handle that overrun condition properly. The FAT32
file system allows maximum file sizes of 4 GB. Instead, the NTFS
file system, which is available under Windows 2000 and XP does not
have any file size limitations (except the harddisk size of course).
One way around this problem would be to configure the recording
software in such a way, that new files are created (and saved)
automatically at fixed time intervals (e.g. each hour a new one).
Specific software would do that without any gaps between the
successive files. However, I'm afraid, that WaveLab, CoolEdit and
SoundForge do not support that mode of operation.
Another solution would be to use a software that supports a sound-
activated recording mode. A threshold comparison would then control
the recording process. This would be appropriate if you want to
record occasional sounds only. The advantage of this method would
be, that the file sizes were much smaller (and locating the
interesting events would be much easier).
I have a very specific recording software, that supports both of
these methods. However, it has been designed primarily for
scientific monitoring purposes and has many other options as a real-
time spectrogram display and more advanced triggering options. It is
therefore not extremely cheap.
