KVR Audio

Some of the sound samples I have (mostly drum samples) are WAV files which have been encoded with OGG vorbis. They are not standard *.ogg files, but WAVs with OGG compression (in explorer, right-click, Properties, Summary Tab, Audio Format).

This kinda sucks, as the Drum Machine VST I use doesn't load internally compressed WAV files.

I tried using Windows Sound Recorder to convert them to standard PCM encoding, but it just created 0kb empty files.

A Google search for "Ogg", "Wav", "compress", "decompress", "PCM" is about as much use as searching for a needle in a haystack.

I guess I'm looking for either:

A) A freeware batch convertor which will simply remove the OGG encoding.

or

B) A website with information about the file structure of compressed WAVs so I can write a simple WAV decompressor in C++.

Any help appreciated.

An audio file editor that can read .OGG and write pure PCM WAVs is what you need.

Just did a test, and Audacity does it for free! (both ways even...)

As unsatisfying as it might sound at first, i had the exact same problem as ceenda (.wav file with ogg compression (who does that even??)) and i just got me Audacity Portable from some IT-Magazine source. After no installation it could open the ".wav"... Problem solved. Not so nice for hundreds of files or from time to time popping up ".wav" disguised .OGG files, but at least it is a free, solution. Thanks C00kie!

Wavosaur will open .ogg files *and* can perform batch processing. Free too.

Good to know. FFmpegYAG for example has problems with it.

As k0llege said, audacity will do it.

Once audio is file-compressed like that, the information lost is not going to be brought back like magic by anything. It's lost, meaning it's gone. So if you mean literal ogg-vorbis, this is a lossy codec. There is no real reconstruction paradigm for this.
If it's a container for FLAC, not the same issue.
