...sting 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.

libFLAC optimizations request
Hello all I am using libFLAC in a corner application, compressing *a lot* of small signals. First is a general question: in our application we have signals in range 5-10 MHz, potentially 40MHz! Is there any potential problem with that?? The mac sample rate is limited in flac, but it doesn't really seem to be a problem. The output is stored as blob in a sqlite database, it *never *needs to be

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?
