The opusenc tool automatically adds metadata - even if you don't specify any. For example, these tags are created by default on my files: ENCODER=opusenc from opus-tools 0.2 ENCODER_OPTIONS=--bitrate 6 --comp 10 --framesize 60 --padding 0 I've tried using `--discard-comments` but that has no effect. I've tried using `--comment ENCODER=` but that adds a duplicate tag. My limited knowledge of C suggests that the following lines in opusenc.c are where the magic happens: https://github.com/xiph/opus-tools/blob/master/src/opusenc.c#L480 https://github.com/xiph/opus-tools/blob/master/src/opusenc.c#L800 So, would it be possible to add a `--no-metada` option to completely suppress any metadata from being written? I realise this is a niche requirement! I'm trying to create tiny audio files where every byte saved is important. I can use Mutagen to remove the metadata, but I'd like a way not to add it in the first place. Thanks Terence -------------- next part -------------- An HTML attachment was scrubbed...
