Files saved under Vista truncated
Files saved under Vista truncated
Files I save in Vista lose their last .1 seconds. The format doesn't seem to matter.
I've noticed that in the program the files are destined for, the wave data can be seen to extend past the end of the file:
The blue line is where playback stops. Goldwave and WMP11 play the file the same way, so it's definitely not the programs that are at fault.
This is on Vista Home Premium with Goldwave 5.20.

Theory,
You may need to wait for an answer from Chris (GoldWave) on this one. Chris hasn't posted to the forum for about a week or so, and there are a couple of un-removed spams.... So, maybe he's busy with something, or otherwise unavailable at the moment.
Or, you may want to send your question directly to GoldWave via the Tech Support Web-Form.
This is probably a Vista-related problem, and most of use here are not running Vista yet. (I'm still quite happy with Win 2K.)
Doug.

I assume you've tried a WAV format. People do report problems with MP3s. The problem with MP3s is usually the opposite... Silence being added to the begining of the file. And, the MP3 problems are not limited to Vista.The format doesn't seem to matter.

Are there any sampling rate/bitrate conversions happening before you save your files? Are you altering the time or pitch? It might help if we knew of any processing you might be doing before you save.Yeah, I have to be precise as I'm dealing with spoken sentences.
Also, what "flavor" of wav (which is a container format, meaning the wav could be encoded a number of different ways, requiring different codecs) are you saving as? 16-bit integer, 32-bit floating, ACM, mp3, etc.?

If you are saving the file in Wave, PCM 16 bit format, it is unlikely that the file itself is truncated. It is most likely a problem with the sound driver ending playback slightly before it should. Many Vista sound drivers still have glitches to work out. It reminds me of a problem with early sound drivers on Windows 2000 where the first 0.1 second or so wouldn't get played. The drivers would skip it or play a small bit of audio from a previously played sound (usually causing a click at the very beginning).
Does it play entirely if you have playback looping enabled in GoldWave?

There is no way to avoid the ACM problem in GoldWave (except adding silence to the end of the file before converting).
Do you have to use the Wave format? If not, you can save in MP3 format or one of the other compressed formats. That would give much better quality than MSADPCM, with even smaller file sizes.
If quality is important, FLAC or Lossless WMA would be about twice the size of the MSADPCM file, but there would be no loss of quality. The file would be identical to the 16 bit version, without any leading/trailing silences or missing endings.

It has to do with the way the audio compression manager works when decoding the last block of compressed MSADPCM audio. It has been like that for a long time.
If you can avoid using MSADPCM and use different compression attributes, that's what I would recommend. See if the MPEG layer 3 attributes are available under the Wave type. If so, that will give better quality and smaller file sizes (but it adds short silences to the ends of the file).
