24bit FLAC

[bloop]

I did a conversion of a 24bit-wav to FLAC.
Then I encoded it back to wav and compared the original wav with the result.
Both sound the same, but the waveform looks different when comparing in wavelab.

While converting the FLAC-encoder (from soundforge, latest version) said "WARNING: legacy WAVE file has format type 1 but bits-per-sample=24".

I searched the web, but didn't found any real clue.

Did the same with a 16bit-wav, there was no difference.

Where did the 24-bit WAV come from?
It looks like the difference is probably between the original WAV specifications, and the new WAV format Extensible type.
Certain apps do not seem to know what the EX type is all about, and have trouble interpreting the headers.

the original wav was recorded with wavelab

some sources on the web says, that flac is not ready to handle 24bit wav properly. Soundforge doesn't even mention 24 bit on their site.

The latest FLAC version 1.2.1 has an option --keep-foreign-metadata, maybe that helps? 24 bit should be possible.

I dunno soundforge just seems buggy with it's flac support. I would use something like foobar or flacfrontend to decompress flac. Another thing to look out for when decompressing - replaygain processing. This was happening to a friend of mine who couldn't figure out why he was getting altered wavforms.

When encoding I did use the latest flac 1.2.1. and did no replay gain (wave should stay original)
