编辑文件内容
CELT is a very low delay audio codec designed for high-quality communications. Its potential uses include video-conferencing and network music performance. This is a maintained branch of the 0.5.1 prerelease of CELT. THIS 0.5.1-X PRERELEASE IS NOT COMPATABLE WITH ANY PREVIOUS OR SUBSEQUENT NUMBERED RELEASE. 0.5.0 aand before as well as 0.5.2 and later use a different API, a different ABI and a different bitstream format. Only other prereleases on this 0.5.1 branch are code, binary or stream compatable with this version. To compile: % ./configure % make To test the encoder: % testcelt <rate> <channels> <frame size> <bytes per packet> input.sw output.sw ...where input.sw is a 16-bit (machine endian) audio file sampled at 44.1 kHz or 48 kHz. The output file is already decompressed. the <rate> parameter is the number of bytes per packet to use. Alternatively, there are now Ogg-based tools in tools/. Use the --help option for details. These are quite similar to the speexenc/speexdec tools. Note that these tools should be used for _testing_purposes_only_; the bitstream format used by CELT-0.5.1 has already been altered in subsequent releases. Files produced by celtenc051 will not be supported by later releases of celt. They will work only with releasein this 0.5.1 branch, and will not be supported in the larger Ogg frameworks.
