uncompress/decompress compressed wave files?
Reply with quote

Hi Ev1 - just started using MadTracker and am in awe of its capabilities! I found a sample site I like but the wave files are apparently compressed and MadTracker refuses to open them. I've searched all over but can't figure out if I can actually convert them to a form that MadTracker accepts. Anyone know how to do this? Thanks in advance.

I figured it out- open Sound Recorder (sndrec32.exe) open the wave file, got to Properties, hit Convert Now. By default the PCM format is shown which works. In Attributes I selected 22 kHz, 16 bit, Stereo. Hit OK and save over the old file and then it works in MadTracker.

why would you want 22khz and not 44,1 (cd quality)? you shoulg get better sounding samples using 44 unless it is 22Khz samples you have already.

Another problem of resampling samples is that the method used can alter the quality. Pro wave editors such as Soundforge and Wavelab have high-q tools for this purpose, and I don't think the algorhythms used in Soundrecorder are top notch.

The problem is indeed most probably that the waves have an odd or a too high sample frequency. If you transform the wave, then go to 16bit / stereo / 44kHz. Even if your source is 22, then it's still useful to upgrade the samples, because it gives better results if you apply effects that add new sound.

as Inge said conversions and conversions may differ in result. for a prolly slightly better outcome, try out http://audacity.sourceforge.net/, it's a free and pretty neat audio editor.

If you get an error message that says "compressed files are not supported" when you try to open the sample, then the wav file probably is in ADPCM format (a compressed wav format). In that case the problem has nothing to do with the sample rate or bit depth. Converting it to a PCM wav file like you did works fine in that case. However, the sample quality will decrease for various reasons as several people have pointed out (if it's audible I don't know).

Thank you all for the in-depth solutions and info! I hope this topic helps other new users that encounter the same problem. Got all my samples working and sounding great.
