Transcoding without meta-data

[MINORISUKE]

Thank you for your reply.
I suppose this is valid both for the internal transcoder as well as the external one such as ffmpeg.

In case
"flac:wav" (or "flac:wav;")
is specified, and this flac file contains meta-data and an externally converted WAV file (for example, converted from flac to WAV with foobar2000 keeping the meta-data) also exists, is the following correct?
(1) The transcoded WAV from flac is without meta-data
(2) The externally converted WAV containing meta-data is streamed out with meta-data.

If yes, is there any method of deleting meta-data contained in the WAV file (conceptually "wav:wav" or "wav:wav;") at the moment of transcoding?
