What features would you like to see in opus-tools? Options

[NullC]

I'm looking for suggested features to get into opus-tools prior to the libopus 1.1 release.

Before I get 1001 suggestions for it: One frequently requested feature which was recently added is flac input in opusenc. I'm contemplating changing opusdec to use the new opusfile library— which would give it seeking and integrated http(s) streaming support. Also already on my todo list are default comment packet padding so updating metadata doesn't require rewriting the files and adding a replaygain tool.

Some people would really like it if opusenc/opusdec supported taking multiple input files e.g. opusenc *.flac but the implicit output file naming is pretty ununixy, and would break the interface and I got flamed all to heck last time I changed the opusenc interface.... so I'm not sure if/how I want to accommodate that usage.

What other things have you found missing?

There are a few things that I'd like to see. In opusenc, an option to force SILK or CELT. Goldwave already does this, and when I encode a 24kbps with SILK in Goldwave, it sounds much better than the opusenc file. This changes when you get down to 16kbps.

Going along with the voice/music detection in the 1.1-alpha, I don't know if it would be feasible, but it would be nice to dynamically scale the bitrate between detected music and voice portions of a clip with user specified bitrates for each, where the user might choose to set a bitrate of, say, 24kbps for voice, and a higher bitrate of 128 kbps for music.

And in opusinfo, a printout or graph of the bitrate vs time in the file, or maybe just a printout of the bitrate each frame, or the average bitrate at a user specified interval, so you could get a listing of the average bitrate every second, or whatever the user might specify. This might be useful for analyzing how your audio is being encoded.
