Rereading my post, I implied that a
VorbisComment inside a FLAC stream could
be larger than a FLAC metadata block.  As the
former must fit inside the latter (when inside a
FLAC stream), the limit for both is the smaller
of the two.

This still looks good.

A VorbisComment can store upto 2^64 bytes
(16 exabytes).  A FLAC metadata block is
limited to 2^24 bytes (16 megabytes).
Therefore, a VorbisComment can be orders of
magnitude bigger than a FLAC metadata block.

https://wiki.xiph.org/Metadata

The advice to use a VorbisComment still looks
good.

Martin

Hi Martjn, and everyone,

Apologies if I have missed the reply, but I think I have not got any comment so 
far on this. That means our new ID request is accepted? What should I do next 
to proceed??  Apparently this is my first time here, so appreciate any advice 
assistance.

Best regards,

Taku

Hi Martijn,

Sorry for the late reply again,
The application we are preparing this time is not exactly similar to Replaygain.

Replaygain as we understand is something which normalize the loudness at 
content provider side, but our application takes different approach. It is 
designed to normalize the loudness at player side, according to the metadata 
embedded within the content, which could be relatively big in its size, so it 
will be unfit for Vorbis comment. Besides that, its concept, format are 
incompatible with Replaygain, and we are putting effort to add additional 
features to that in the future, which makes metadata size even bigger.
The Player compatible with will only be the one we are developing, for now.

Best regards,

Taku

Hi,

I'm sorry, but that link doesn't seem to include anything specific about the 
metadata itself. The reason I'm asking is because, for player compatibility, it 
is probably much easier to use a vorbiscomment to store metadata. Replaygain 
normalisation uses Vorbiscomment too. Most FLAC players already read 
vorbiscomment, so for implementing plugins, this is probably much easier.

Kind regards, Martijn van Beurden

Hi,

Could you please describe your application? While it is possible to use FLAC 
Application metadata blocks, it isn't common practice.

Kind regards, Martijn van Beurden
