Hi!
Maybe you already know fpMP3Enc, my multicore MP3 encoder... This time, I'd like to introduce my multicore FLAC encoder. You can download the binaries here. The package contains Win32 binaries for XP, Vista and 7, and Win64 binaries for Vista and 7. The FLAC encoder is part of my "fpStream" project. The command-line to convert a WAV file to FLAC is as follows: CODE FPSTREAM.EXE readfile in -f <wav-filename> + wavin wav -s in + fpflacenc enc -s wav [-<compression level>] + writefile out -s enc -f <flac-filename> The benchmarks so far: I used the same test suite as in fpMP3Enc (Intel Q9450, 61 WAV files, about 5 hours playing time). The compression level was 5. The files were encoded one after the other, not in parallel. - flac 1.2.1: 3 min 26 secs - fpFLAC x64: 1 min 13 secs So, the speedup was 2.8x. This is quite good if you consider that this version does not contain any SSE optimizations. What's missing: - SSE optimizations - Metadata support (tags, seek points etc.) - free of bugs And some limitations: - Win32 version: The total WAV file size sum must not exceed 400MiB(? - not sure). - Win64 version: The total WAV file size sum must not exceed 400GiB. - Input: WAV 16-bit stereo, 44.1kHz Comments and feedback are welcome!

I cannot wait for this to be ready for production so to speak!
Any chance @ GPU support? |

QUOTE (NuSkooler @ Dec 23 2009, 18:16)  I cannot wait for this to be ready for production so to speak! Well, the truth is, I don't know if fpFLAC has a future. The feedback is very, very poor. QUOTE Any chance @ GPU support? I will add GPU support into my framework and if the fpFLAC project will be continued it will also support GPUs. |
