What is the status of the oggpcm project?
I'm investigation solutions to the following problem: losslessly encode
double-precision mutli-channel timeseries data in a format that is
compatible with free (libre) internet streaming technologies and that
permits diverse metadata to be encoded with the stream. flac isn't
suitable because it only supports integer data, lossy encodings are not
suitable because they're lossy. .wav files support lossless double
precision data but I don't know if there are ways to stream data in that
format over the internet, and anyway they don't provide a mechanism for
encoding the diversity of metadata I'm looking to store. The data stream
is collected as part of a scientific experiement and we'll want to be able
to encode information about the instruments that collected it and
additional information not normally associated with audio data like what
units it has.
oggpcm appears to be perfect: my understanding that it should be able to
provide lossless double-precision storage and (I assume) can be
multiplexed into an ogg container stream along with other oggpcm streams
and metadata streams and send over the internet.
But I can't find any code associated with the project. Is there any?
When might someone expect to see a liboggpcm? Thanks,
