...nal. It' clear that current settings, re-creating windows, cpu-dependent functions, etc could be kept around. I was not quickly able to extract all the necessary initialization from "init_stream_internal_" into a new "FLAC__stream_encoder_restart" function.

Hello again, After some time, I succeeded in splitting "flush" and "restart" functions. A quick measurement gives me ~25% speed improvement, which is quite a lot. Of course this optimization is specific for this use case (many short signals). Is this interesting for the project? I would gladly contribute it... If yes, how should I share it? As a patch against current git?

...ere is no existing way to avoid having the encoder create the Vorbis comment metadata, but there might be a way to delete that particular metadata before the file is saved. A closer look at how metaflac creates a file without Vorbis comments should help.
