Hello, All. I wrote an encoder-decoder based on example from OGG-Vorbis SDK. This encoder can encode a large amount of small WAV-files with equal parameters into one sound archive. Then I decode this sound archive back into large amount of small WAV-files. Theese files are different from source files, but each of them can be normally played by Windows. And now I can't correctly encode these decoded files into sound archive again. The behavior of encoder is the following: 1) it normally encodes first 10-20 files and after that the time of encoding for each file starts to grow The vorbis_analysis_blockout() function starts to return 0 (in normal mode it returns 1). The time of executing vorbis_analysis_buffer() function starts to grow (in normal mode this time is very small). It seems like the encoder processes vorbis_analysis_blockout() function only when the end-of-stream flag is set to 1 (at the end of the last file). 2) According to (1) the encoder hungs up when I'm trying to encode about 9000 files. 2) When I listen the resulting sound archive the first file is playing with artefacts. Does anybody know how can it be repaired? Thank you. Aleksey
